Safety of titanium mesh for orbital reconstruction.

During the past several decades, the standard of care for orbital reconstruction after trauma has been autogenous bone grafts. Complications of bone grafts, including donor site morbidities such as scar alopecia and graft resorption with delayed enophthalmos, have inspired an interest in the use of alloplastic substitutes such as titanium. Titanium's role in orbital reconstruction was limited originally to small orbital defects, and as an adjunct to bone grafts. More recently, clinical studies have documented the sole use of titanium mesh to reconstruct large orbital defects. This study sought to document further the safety and efficacy of titanium mesh in reconstructing large orbital defects after facial trauma, with more extensive follow-up compared with previous studies. In the current study, 55 patients with 67 orbital fractures underwent orbital reconstruction with titanium mesh over a 5-year period. Associated fractures were reduced anatomically and fixed rigidly. For the analysis, 44 patients with 56 orbital fractures had adequate follow-up (mean, 44 months). An abscess developed in one patient who received high-dose steroids for 72 hours before reconstruction. She was treated with broad-spectrum intravenous antibiotics and bedside incision and drainage, and did not require removal of the titanium mesh. No patient in the current series required removal of the titanium mesh. A single case of uncorrected enophthalmos was treated with bone grafting rather than mesh revision. Large orbital defects can be reconstructed using titanium mesh with good functional results and minimal risk for infection. This study covered the authors' first 5 years using titanium. They have now used titanium mesh in orbital reconstructions for more than 10 years, without any additional cases of infection.

Ex vivo renal artery reconstruction.

Ex vivo renal artery reconstruction and autotransplantation is a relatively recent addition to the surgical armamentarium for renal vascular hypertension. Ten consecutive patients were considered for this surgical therapy and form the basis of this communication. The patients were treated by a combination of methods including bilateral ex vivo reconstruction, unilateral in situ and contralateral ex vivo reconstruction, and unilateral ex vivo reconstruction and contralateral nephrectomy. Replacement of the diseased segment of the renal artery in all ex vivo reconstruction consisted of arterial autografts including hypogastric artery, splenic artery, common iliac, and external iliac artery. In the ex vivo reconstruction, the ureter was either left intact or was transected and reconstructed by standard ureterovesicle implantation. After surgery all patients became normotensive without antihypertensive medication. Although this is a relatively small series, the uniform good results in these patients with extensive disease suggest that ex vivo renal artery reconstruction is a safe and effective method of treatment. Thus, it should be more widely applicable, expecially in those patients with renal vascular disease who were previously thought to be inoperable or eligible for nephrectomy only.

Hepatic vein reconstruction for resection of hepatic tumors.

SUMMARY BACKGROUND DATA: Involvement of the hepatic veins requiring reconstruction has traditionally been considered a contraindication to resection for advanced tumors of the liver because the surgical risks are high and the long-term prognosis poor. Recent advances in liver surgery gleaned from split and live donor liver transplantation that necessitate hepatic vein reconstruction can be applied to hepatic resection in some cases. METHODS: Sixteen patients who underwent hepatic resection requiring hepatic vein reconstruction from 1996-2001 were reviewed. The mean age was 43 years (range 2-61). Nine patients were resected for hepatocellular carcinoma (HCC), five patients for colorectal metastases, and one patient each for hepatoblastoma and cholangiocarcinoma. In six patients with HCC and cirrhosis, the right hepatic vein was reconstructed to provide venous outflow to liver segments not adequately drained by a remaining major hepatic vein. Four of these six patients required the use of Gore-Tex (W. L. Gore & Associates, Inc., Newark, DE) interposition grafts. In the 10 other cases the entire venous outflow from the remnant liver was reconstructed or reimplanted into the inferior vena cava primarily (n = 8) or using segments of the portal vein from the resected side of the liver as a graft (n = 2). Ex-vivo procedures with the use of veno-venous bypass were required in two cases and in-situ cold perfusion of the liver was used in one case. RESULTS: There were two perioperative deaths (12%). One patient died of liver failure 3 weeks after right trisegmentectomy with reconstruction of the left hepatic vein and one patient died at 3 months after resection due to sepsis from a segment of small bowel that perforated into a diaphragmatic hernia. Four patients had evidence of postoperative liver failure that resolved with supportive management and one patient required temporary dialysis. All vascular reconstructions were patent at last followup. With median followup of 23 months, 3 patients have died of recurrent malignancy at 14, 18 and 30 months, while an additional patient went on to die of progressive liver failure at 22 months. Actuarial 1 and 3 year survival was 88% and 50% respectively. CONCLUSION: Hepatic vein involvement by hepatic malignancy does not necessarily preclude resection. Liver resection with reconstruction of the hepatic veins can be performed in selected cases. The increased risk associated with the procedure appears to be balanced by the possible benefits, particularly when the lack of alternative curative approaches is considered.

Autogenous reconstruction of the temporomandibular joint.

Recently, the temporomandibular joint has been reconstructed with a variety of alloplastic materials; however, functional results are often limited, and long-term stability of the reconstruction is questionable. In contrast, costochondral rib grafting with rigid internal fixation and a temporoparietal fascia flap allows complete functional reconstruction of the temporomandibular joint with autogenous tissue. Thirteen joint reconstructions in 11 patients were followed for up to 7 years and stability of the reconstruction was confirmed. The anterior incisal opening improved from a mean of 14 to 31 mm. Normal occlusal relationships were either reestablished or preserved. Joint pain was ameliorated. The preferred reconstruction of the temporomandibular joint is by autogenous tissue for disc and joint replacement. The treatment provides primary therapy in total joint reconstruction where tumor, trauma, or failed prosthetic joint replacement necessitate complete reconstruction.

Vascular iliac crest with inner table of the ilium as an option in maxillary reconstruction.

Reconstruction of large maxillary defects has been a long-standing challenge to the reconstructive surgeon. Total maxillary reconstruction is desirable but often not possible; ideally, this would provide all the anatomical structural support, function, and esthetics missing because of the defect. A case is presented in which all the criteria for total maxillary reconstruction have been fulfilled. The patient is a 60-year-old man who had wide excision of his maxilla for ameloblastoma, followed by temporal bone flap reconstruction, which failed. He presented to our institution for further evaluation and possible treatment options; these were discussed with the patient and the multidisciplinary team that deals with congenital and acquired deformities in the head and neck area. An iliac crest free flap that included the inner table of the ilium based on the deep circumflex iliac artery was used for the reconstruction. The procedure is described, including restoration of a nasal lining. Osseointegrated implants were used for dental rehabilitation. Ameloblastoma is briefly discussed. The goals of maxillary rehabilitation and obstacles to obtaining those goals are presented. Options available for maxillary reconstruction are discussed, along with some of their advantages and disadvantages, as is the reason why the iliac crest free flap with the inner table of the ilium was chosen. An iliac crest free flap with microvascular anastomosis to facial vessels was used to reconstruct a large maxillary defect. Osseointegrated implants were used to facilitate dental rehabilitation. Our patient has excellent restoration of oronasal function with a satisfactory esthetic result.

Anterior cruciate ligament reconstruction with patellar autograft tendon.

There are many techniques, graft choices, and outcome studies evaluating anterior cruciate ligament reconstruction. The current authors specifically look at reconstruction with the patellar tendon from a scientific perspective. Miniopen, endoscopic, and two-incision operative techniques in addition to hamstring versus patellar tendon autograft reconstructions are compared via randomized prospective studies. A review of all studies evaluating arthroscopically-assisted anterior cruciate ligament reconstruction with patellar tendon was conducted. The authors found arthroscopically-assisted anterior cruciate ligament reconstruction to have a high short-term stability rate, extremely high patient satisfaction level, and a low postoperative complication rate. When the endoscopic technique was compared with the two-incision technique, there were no major differences. The difference between patellar tendon and hamstring autograft reconstruction can be described best as subtle, except for the consistent finding of an increased activity level in the patellar tendon group. When the principles of anterior cruciate reconstruction are followed, one can expect consistent results with patellar tendon autograft reconstruction.

Validation of three-dimensional reconstructions of knee anatomy: CT vs MR imaging.

This is the first investigation to validate the accuracy of spatial measurements based on computer-generated three-dimensional (3D) reconstructions of CT and magnetic resonance (MR) scans. Standard 3D reconstructions of one fresh frozen cadaveric knee specimen with implanted stereotactic reference markers were created. These reconstructions were based on the data from CT and MR scans performed before and after the resection of extraosseous soft tissues. The distances between the stereotactic reference markers in the 3D reconstructions were compared with the same measurements of the specimen using a Bridgeport milling machine as a precision 3D digitizer. The accuracy of intermarker distance measurements averaged 99% for CT-based reconstructions compared with 97.5% for MR-based reconstructions. Planar slices at a predetermined level and orientation through the femoral condyles were created by sequential milling of the specimen and were compared with reconstructed oblique planar CT and MR slices at the same level and orientation. The accuracy of condylar dimensional measurements was 94% for CT and 93% for MR compared with measurements of the milled slices. Three-dimensional reconstructions based on CT and MR scan data were of equally high quality and were unaffected by the status of the soft tissues.

Reconstructive strategies for radioulnar dissociation: a biomechanical study.

Radial head fracture combined with disruption of the soft-tissue restraints to proximal radial migration is defined as radioulnar dissociation. This injury often involves irreparable radial head fracture. When excised, management has emphasized the use of silicone implants to prevent proximal migration. However, concerns regarding silicone use led to the search for reconstructive alternatives. The purpose of this study was to compare reconstructive methods for radioulnar dissociation. Biomechanical testing to measure radial displacements under physiologic loads was performed on fresh-frozen cadavers after radial head resection. The central interosseous membrane (IOM) was disrupted to simulate radioulnar dissociation. This was followed by an orderly reconstructive sequence including radial head replacement with both silicone and titanium implants as well as a newly described flexible IOM reconstruction. Calculated stiffness values were used for comparison. Silicone implants provided no statistical improvement in forearm stiffness compared with the disrupted membrane state. Significant improvements were achieved with titanium implants and flexible IOM reconstruction, which restored stiffness to 89% and 94% of normal, respectively. No statistical differences were identified between these successful methods. Titanium implants combined with flexible reconstruction increased stiffness to 145% of normal. Further doubt is cast on the role of silicone implants in the management of radioulnar dissociation. Titanium implants and flexible IOM reconstruction appear to be wiser reconstructive choices.

Arthroscopic reconstruction of the posterior cruciate ligament with quadruple hamstring tendon graft: a double fixation method.

BACKGROUND: Surgical reconstruction is indicated for posterior cruciate ligament (PCL) reconstruction for a grade III or IV injury, combined ligament or meniscus injuries, and chronic symptomatic posterior instability. Considerable controversy continues over the choice of graft tissues. Hamstring tendon has been popular in recent years. The purpose of this study is to prospectively assess the outcomes of PCL reconstruction using quadruple hamstring tendon autograft with a double-fixation technique at minimal 2-year follow-up. METHODS: Only patients who received PCL reconstruction without combined associated posterolateral injury reconstruction were included in the series. A hamstring tendon graft is composed of a quadruple-stranded semitendinosus tendon and gracilis tendon 10 cm in length. An arthroscopic technique using a two-incision method and a double-fixation technique were used. Clinical assessments were performed for 30 patients, of which 27 were available for final outcome analysis. Clinical review of patients included the Lysholm knee scores, International Knee Documentation Committee (IKDC) scores, thigh muscle assessment, and radiographic evaluation. RESULTS: On the Lysholm knee rating, 89% of the patients demonstrated good or excellent results in the final assessment. In the IKDC rating analyses, 56% of the patients revealed 3- to 5-mm ligament laxity. Four patients (15%) had grade II laxity. For the IKDC final rating, 26% were normal and 55% were nearly normal. Seventy-eight percent of the patients had less than a 10-mm difference in thigh girth between their reconstructed and opposite limbs. CONCLUSION: Arthroscopic PCL reconstruction with quadruple hamstring tendon autograft appears to produce acceptable results at a minimal 2-year follow-up. The four-stranded hamstring tendon graft is adequate in graft size and associated with minimal harvesting morbidity. The double-fixation method for the graft could provide a rigid fixation. We believe that this technique could afford good ligament function after reconstruction and could be a reasonably acceptable choice for PCL injury.

Resource utilization and patient morbidity in head and neck reconstruction.

Many papers have addressed the technical aspects of free tissue transfer in head and neck cancer patients. However, there has not been a critical assessment of the impact of free tissue transfer on resource utilization and patient morbidity compared with pedicle flap reconstructions. Two cohorts of patients derived from 245 consecutive reconstructions were tightly matched by age, site, stage, and histology, yielding 44 patient pairs differing in method of reconstruction. Patients undergoing free flap reconstruction spent more time in the operating room than those reconstructed with pedicled flaps (993 min vs. 777 min, P < 0.0001). The group with free flap reconstruction spent fewer days in the surgical intensive care unit and hospital (2 days vs. 2.5 days; 18.5 days vs. 22.6 days). This difference is attributed to the paucity of postoperative complications in the group with free flap reconstruction (fistula formation 4.5% vs. 21%, P < 0.04). These data indicate that the continued use of sophisticated reconstructive techniques in head and neck cancer patients is economically sound as assessed by patient morbidity and resource utilization.

Revision ossicular reconstruction with the titanium Kurz prosthesis.

OBJECTIVE/HYPOTHESIS: One European multicenter study has reported favorable outcomes after ossicular reconstruction with the titanium Kurz prosthesis. At the time of this study, however, no study has analyzed its outcomes when used for reconstruction after prior failure with another implant (revision reconstruction). The study reports our experience with the titanium Kurz prosthesis for revision ossicular reconstruction. STUDY DESIGN: A retrospective review was made of all revision ossicular reconstructions at our institution from October 1998 to September 2001. METHODS: Seventeen cases were reviewed. Patients were divided into two groups: patients who underwent revision ossicular reconstruction with the Kurz prosthesis and patients who underwent revision ossicular reconstruction with another prosthesis (the "other" group). Audiograms were reviewed and air-bone gaps were calculated for each patient. RESULTS: The average postoperative air-bone gap after Kurz revision was 15.6 dB, a statistically significant improvement over the average postoperative air-bone gap from the "other" revision group (P =.022). CONCLUSION: The titanium Kurz prosthesis has been an effective implant at our institution for revision ossicular reconstruction. Future research should focus on a prospective, randomized trial comparing the Kurz prosthesis with other prostheses currently in use.

Clinical validation of fully 3-D versus 2.5-D RAMLA reconstruction on the Philips-ADAC CPET PET scanner.

INTRODUCTION: Fully three-dimensional (3-D) reconstruction algorithms have the potential to better utilize PET data acquired in true 3-D acquisition modes, as compared to 2-D approaches involving data reduction through rebinning procedures followed by a 2-D or 2.5-D reconstruction. Our previous studies, involving simulated and real phantom data from PET scanners working purely in 3-D acquisition mode, showed that the fully 3-D reconstruction approaches bring appreciable improvement on physical measures and visual image quality as well. Reconstruction procedures utilized in those studies were based upon the row action maximum likelihood algorithm (RAMLA) implemented on our clinical scanners. The purpose of this study was to investigate if the fully 3-D RAMLA reconstruction software brings an appreciable improvement in clinical image quality and reader confidence. MATERIALS AND METHODS: Ninety patient scans acquired on the Philips CPET scanner at our institution were reconstructed using 2.5-D RAMLA and 3-D RAMLA with differing reconstruction parameters. These scans were blindly presented to four experienced PET scan readers who graded various aspects of image quality. RESULTS: Our study concluded that 3-D RAMLA on the CPET scanner reduces artifacts and image noise and improves clinical confidence in interpreting PET images. CONCLUSION: This study led to the routine use of 3-D RAMLA reconstruction on the CPET scanner at our institution.

A comparison of factors affecting aesthetic outcomes of TRAM flap breast reconstructions.

The aesthetic results of TRAM flap breast reconstructions were assessed in 237 consecutive breast cancer patients. Nine independent judges, none of whom were plastic surgeons or members of the reconstructive team, assigned an aesthetic score to each patient after viewing postoperative photographs. We found that bilateral reconstructions were aesthetically superior to unilateral reconstructions (p = 0.0013), that immediate reconstructions were aesthetically superior to delayed reconstructions (p = 0.0001), and that previous irradiation of the chest wall reduced the mean aesthetic score (p = 0.0010). We also found that the mean aesthetic score assigned to patients who had reconstructions with free TRAM flaps was superior to that assigned to those who had reconstructions with conventional TRAM flaps, but when tested by multiple regression analysis, this trend was not statistically significant (p = 0.2972).

Cost and outcome of osteocutaneous free-tissue transfer versus pedicled soft-tissue reconstruction for composite mandibular defects.

Thirty-nine patients underwent reconstruction of composite mandibular defects following resection for squamous cell carcinoma. Thirty-four underwent immediate reconstruction, while 5 were reconstructed secondarily. Twenty-one received soft-tissue reconstruction only with a pectoralis major myocutaneous flap, 14 underwent osteocutaneous free-tissue transfer, and 4 received a reconstruction plate with free-tissue transfer for soft-tissue coverage. The mandibular defects in the pectoralis major myocutaneous flap group tended to be posterolateral, while free-tissue transfer defects were more severe, usually involving the anterior mandible. Length of surgery and duration of intensive care unit care were significantly longer for free-tissue transfer patients, while flap complications were more common in the pectoralis major myocutaneous flap patients. Facial appearance scores were higher for the free-tissue transfer group by both patient and physician assessment. Social function, speech, and oral function did not differ significantly. Patients reconstructed secondarily with free-tissue transfer reported significant improvement in appearance, oral continence, and social function, with little change in speech intelligibility, deglutition, or diet tolerance. The cost of the main hospitalization was significantly higher in the free-tissue transfer group than in the pectoralis major myocutaneous flap group, although when the costs of subsequent hospitalizations are included, the difference in total cost narrows. Despite more adverse defects, free-tissue transfer provided more predictable aesthetic results and expeditious return to normal social function than did pectoralis major myocutaneous flap reconstruction. The fiscal impact of these complex reconstructions is, however, significant. Cost-containment issues are presented and recommendations are made.

Comparison of resource costs of free and conventional TRAM flap breast reconstruction.

Resource costs, which are the costs to the hospital of providing a service, were measured for 154 patients who underwent mastectomy and immediate breast reconstruction with TRAM flaps. Unilateral and bilateral reconstructions were evaluated separately. The resource costs required to perform mastectomy and reconstruction with free TRAM flaps were then compared with those required when conventional TRAM flaps were used. The mean total resource cost in the free TRAM group was slightly higher than in the conventional TRAM group, but the difference was small (4.1 percent) and not statistically significant (p = 0.290). The mean resource cost of performing bilateral mastectomy and reconstruction was higher than that of unilateral mastectomy and reconstruction, but the difference was only 5.0 percent (p = 0.046). This study shows that the cost to an institution of providing breast reconstruction with free TRAM flaps is not significantly higher than that of performing reconstruction with conventional TRAM flaps. Also, our findings show that the resource costs of performing bilateral mastectomy and reconstruction are not much higher than those of treating only one breast.

A comparison of morbidity from bilateral, unipedicled and unilateral, unipedicled TRAM flap breast reconstructions.

A large series of women who had undergone bilateral, pedicled TRAM flap reconstructions were compared with women who had had unilateral, unipedicled TRAM flap procedures to determine whether a bilateral TRAM flap breast reconstruction had significant additional morbidity. The records of all women who underwent either a bilateral or unilateral pedicled TRAM flap breast reconstruction through the Emory Clinic from 1987 to 1994 (n = 257) were retrospectively analyzed with respect to general, breast (fat necrosis, flap loss, and cellulitis), and abdominal (hernia, skin loss, and cellulitis) complications. By using logistic regression, risk factors for these complications were determined. The incidence of fat necrosis and partial flap loss was not significantly different among bilateral patients compared with patients with unilateral TRAM reconstructions (10.0 percent versus 12.6 percent, p = 0.64 and 3.8 percent versus 5.5 percent, p = 0.74, respectively). The rate of hernia formation in the bilateral TRAM flap patients (5.4 percent) was similar to that of unilateral patients (3.9 percent, p = 0.80). Significant factors for any complication in both patient populations included obesity, smoking, and prior irradiation. The type of breast reconstruction was not a significant factor for any breast or donor-site complication. A bilateral TRAM reconstruction showed a weak association with general complications. Review of the Emory Clinic experience with unilateral and bilateral pedicled TRAM flap reconstructions from 1987 to 1994 was able to detect no significant additional rate of complications for bilateral pedicled TRAM flap breast reconstructions compared with unilateral unipedicled TRAM flap procedures.

Sensation recovery on innervated radial forearm flap for hemiglossectomy reconstruction by using different recipient nerves.

The objectives of this study were (1) to determine the extent of sensory recovery on hemitongues reconstructed with innervated radial forearm flaps and (2) to assess the influence of various clinical and surgical factors over the return of sensation, including the use of different recipient nerves for neurorrhaphy. Twenty-eight patients with tongue cancer who underwent hemiglossectomy and primary reconstruction with innervated radial forearm flaps over a 3-year period were studied. Mean postoperative follow-up was 18.2 months (range 6 to 32 months). Sensory recovery was assessed in a blind manner by two examiners that used (1) static two-point discrimination, (2) light touch sensation, (3) pain perception, and (4) hot and cold temperature perception. Different surfaces were assessed with each method on the reconstructed hemitongue and on the intact contralateral hemitongue (used as control). The following factors and their relationship with flap sensory recovery were analyzed: age, smoking history, size of the reconstructed defect, administration of postoperative radiation therapy, recipient nerve, and neurorrhaphy technique. Comparative statistical analysis (p < 0.05) between both hemitongues was performed using paired t test followed by Bonferroni correction for static two-point discrimination and light touch sensation. Fisher exact test analysis was used for pinprick and hot and cold temperature perception. The control side was ignored in analyzing the effects of the risk factors. The tip, dorsal aspect, ventral surface, and floor of mouth on the reconstructed hemitongue had comparable static two-point discrimination when compared with the intact hemitongue. Light touch sensation was also similar in the tip and dorsal aspect of both hemitongues; however, a statistically significant difference (p < 0.05) was observed on the ventral surface and floor of mouth of the reconstructed hemitongues. Likewise, pain perception was significantly decreased in the floor of the mouth, compared with other surfaces. No clearly dependent association was established between return of flap sensation and age, tobacco use, and size of the reconstructed defect. Light touch sensation, pain, and temperature perception were significantly decreased when the patients had received postoperative radiation therapy. In addition, all four sensory tests were significantly diminished (p < 0.05) when the recipient nerve used for neurorrhaphy was a nerve other than the lingual or the inferior alveolar nerve, and also when an end-to-side nerve repair was used. Sensation recovery of the innervated radial forearm flap after hemitongue reconstruction approaches normal compared with the contralateral intact hemitongue. Lower return of sensation may be anticipated in patients who receive postoperative radiotherapy. Good recovery of sensation is predictable when either the lingual or inferior alveolar nerve is used for neurorrhaphy, in contrast to using other recipient nerves.

Oromandibular reconstruction with the radial-forearm osteocutaneous flap: experience with 60 consecutive cases.

One of the more difficult problems in reconstructive surgery of the head and neck is replacement of bone and soft tissue lost because of injury, osteomyelitis, or malignancy. The radial-forearm osteocutaneous flap is an accepted choice for oromandibular reconstruction. This study was undertaken to review one center's experience with 60 consecutive cases of oromandibular reconstruction with the radial-forearm osteocutaneous flap. Records of the 38 men and 22 women (mean age, 60 years; range, 26 to 86 years) were reviewed for tumor location, defect and bone length, flap failure rate, recipient- and donor-site complications, length of surgery, and hospital stay. Cancer resection was the reason for 97 percent of reconstructions; 33 percent of flaps were used to reconstruct a lateral defect of the mandible, 40 percent a lateral-central defect, and 27 percent a lateral-central-lateral defect. Mean skin flap size was 55 cm2 (range, 15 to 117 cm2) and mean bone length, 9.4 cm (range, 5 to 14 cm). The microvascular success rate was 98.3 percent. Complications included fracture of the donor radius (15 percent), nonunion of the mandible (5 percent), and hematoma (8.3 percent). These results are comparable to results reported in the literature with other radial forearm flaps. The free radial osteocutaneous flap is a safe and reliable choice for mandibular reconstruction. It offers sufficient bone to reconstruct large defects and can provide adequate pedicle length for vessel anastomosis to the contralateral side of the neck. The above attributes make the radial forearm osteocutaneous flap one of the "first line" flap choices for oromandibular reconstruction.
