Pre-expanded ultra-thin supraclavicular flaps for (full-) face reconstruction with reduced donor-site morbidity and without the need for microsurgery.

BACKGROUND: The expanded supraclavicular island flap, as described in 1997 by the senior author (Pallua), is a useful tool for total facial reconstruction, providing satisfactory results without microsurgical prefabrication. The authors report the use of this technique in 12 patients requiring large flaps who presented with extensive facial scarring that had been previously reconstructed using disfiguring, pigmented skin grafts. METHODS: On the basis of their anatomical dissection studies and knowledge of the constant anatomy of the supraclavicular artery and two draining veins, the authors carefully inserted tissue expanders under the supraclavicular island flaps. After the flaps were expanded, all scars were removed and the covering flaps were transferred into place. Sixteen pre-expanded supraclavicular island flaps were used in 11 patients. RESULTS: There were no complications. CONCLUSIONS: The authors present a method of facial reconstruction that has the advantages of creating a large amount of thin tissue of both good color and texture, without the disadvantages of donor-site morbidity, lengthy operative time, and high cost. In their opinion, this is the method of choice for total facial reconstruction.

Expansion of the socket and orbit for congenital clinical anophthalmia.

BACKGROUND: Congenital clinical anophthalmia requires fitting an artificial eye, achieving a pleasing aspect of the palpebral apparatus, and stimulating growth of the orbit, as well as of the entire midface. METHODS: Out of 25 patients with clinical anophthalmia, 22 were treated according to a new protocol (first described by Wiese et al. in 1999) and followed for up to 6 years. In 10 patients, anophthalmia was bilateral, in nine patients, it was on the right side only and in three it was on the left side only. Treatment consisted of implantation of an osmotic expander to first stimulate growth of the conjunctival sac and eyelids followed by serial implantation of osmotic expanders to stimulate growth of the orbit (and thus of the midface). The material used was a copolymer of methylmethacrylate and N-vinylpyrrolidone. RESULTS: Fitting of an artificial eye was without any problem within the first year of life for the most part. Growth of the orbit was stimulated by more than 65 percent of a healthy one. Aesthetically, the results were very largely pleasing. Complications were encountered, especially when the wrong expander sizes had been implanted. CONCLUSION: Using osmotic expanders of this type, through a staged therapy of minor operations, promises to achieve all goals before the child enters school.

Unilateral postoperative chest wall radiotherapy in bilateral tissue expander/implant reconstruction patients: a prospective outcomes analysis.

BACKGROUND: Implant reconstruction has a major role to play in breast reconstruction, as some patients neither wish nor are suitable for autogenous reconstruction. The suitability of implant reconstruction in patients who may receive postoperative, adjuvant radiation therapy has not, however, been fully clarified. The purpose of this study was to evaluate complications, capsular contracture, aesthetic outcomes, and patient satisfaction in patients who have undergone bilateral tissue expander/implant reconstruction and unilateral, post exchange, adjuvant radiotherapy. In this study population, the effect of radiation can best be appreciated because the nonirradiated breast acts as a control. METHODS: A review of all bilateral tissue expander/implant reconstructions at a single cancer center was undertaken. Twelve patients who underwent bilateral expander/implant reconstruction and unilateral postexchange radiotherapy were eligible for participation. A prospective evaluation of complications, cosmesis, and patient satisfaction was performed. The evaluation of cosmesis and patient satisfaction was executed for 10 of the 12 patients, as two were dead at the time of follow-up. RESULTS: Mean follow-up was 23.5 months (range, 12 to 58.5 years). In 40 percent of patients, there was no discernible difference in capsular contracture between the irradiated and nonirradiated breasts. In 50 percent of patients, the irradiated breast demonstrated increased contracture by a single modified Baker grade. In 10 percent of patients, contracture of the irradiated breast was two modified Baker grades greater than that of the nonirradiated side (grade III versus grade I). CONCLUSION: For the majority of patients, the degree of capsular contracture was higher on the irradiated side, yet overall symmetry, aesthetic results, and patient satisfaction remained high. These data support the conclusion that immediate, bilateral breast reconstruction using tissue expansion and implants is an acceptable option for the subset of patients who may undergo unilateral, postexchange radiotherapy.

A single surgeon's 12-year experience with tissue expander/implant breast reconstruction: part I. A prospective analysis of early complications.

BACKGROUND: Multiple prior reports are conflicted regarding the true incidence of complications following implant-based breast reconstruction. A review of a single surgeon's extensive experience with tissue expander/implant reconstruction provides the opportunity to critically evaluate outcomes in a uniformly treated patient population. The objective of this study was to analyze the development of early complications in patients following two-stage implant breast reconstruction. METHODS: A review of all tissue expander/implant reconstructions performed by a single surgeon over the 12-year period from July of 1992 to June of 2004 was performed. A prospectively maintained database was analyzed with respect to reconstructive and early complication data on 1522 reconstructions in 1221 patients. Early complications were defined as those occurring 12 months or less from initiation of reconstruction. RESULTS: The overall rate of early complications was 5.8 percent; the rate of premature expander removal was 2.7 percent. The most common complication was infection (2.5 percent). The incidence of complications after tissue expander insertion (8.5 percent) was significantly higher than that after the exchange procedure (2.7 percent). The rate of complications was significantly higher in patients with a history of preoperative chest wall irradiation. There was no difference in the incidence of complications in patients who were expanded during chemotherapy and those who were not. CONCLUSIONS: Tissue expander/implant reconstruction is a safe, reliable method of reconstruction with minimal early complications. Early complications are more common after expander insertion. Chemotherapy administered during tissue expansion does not increase the rate of complications. The rate of complications, although higher in previously irradiated patients, remains low.

Management of gestational gigantomastia.

BACKGROUND: Gigantomastia of pregnancy is a rare, severely debilitating condition characterized by massive enlargement of breasts and resulting in tissue necrosis, ulceration, infection, and, occasionally, hemorrhage. Typically, resolution of breast hypertrophy to near prepregnancy size occurs in the postpartum period. Treatment is controversial. METHODS: The authors present a patient with gestational gigantomastia for whom nonoperative management failed and who subsequently required bilateral mastectomies. In addition, the authors performed a comprehensive review of reported cases and generated a treatment algorithm. RESULTS: The patient tolerated the mastectomies well and went on to deliver a healthy child. Postpartum delayed breast reconstruction with tissue expansion and implant placement yielded good results. The literature review demonstrates that medical management has successfully avoided surgery during gestation in 39 percent of cases since 1968. However, 35 percent of patients eventually underwent breast reduction (12 percent) or mastectomy (88 percent) during pregnancy. Spontaneous or elective termination of the pregnancy accounted for 30 percent of outcomes. Patients who underwent breast reduction and then became pregnant had a 100 percent (four of four patients) chance of recurrence. Two women had mastectomy and subsequent pregnancies. One woman developed multiple small areas of recurrence that were surgically excised. The other woman had two additional pregnancies with no recurrence of symptoms. CONCLUSIONS: Medical therapies to manage gestational gigantomastia are inconsistent in outcome. Since some patients respond, these therapies are worth trying. However, if the patient and/or fetus are experiencing significant morbidity, then surgical intervention is warranted. Breast reduction or mastectomy with delayed reconstruction is the preferred procedure. If the mother is considering future pregnancies, mastectomy offers the lowest risk of recurrence.

A single surgeon's 12-year experience with tissue expander/implant breast reconstruction: part II. An analysis of long-term complications, aesthetic outcomes, and patient satisfaction.

BACKGROUND: Few reports have critically evaluated long-term outcomes following two-stage implant reconstruction. The objective of this study was to evaluate long-term aesthetic results, late complications, and patient satisfaction following tissue expander/implant breast reconstruction. A single surgeon's extensive experience with implant-based reconstruction provides an opportunity to evaluate these results in a uniformly treated patient population. METHODS: A total of 1522 tissue expander/implant reconstructions were initiated in 1221 patients from July of 1992 to June of 2004. Data on a cohort of 315 patients (410 reconstructions) with a minimum of 1 year of follow-up were entered into a prospectively maintained outcomes database. Overall aesthetic grade, capsular contracture grade, patient satisfaction, and late complications were prospectively evaluated, and outcome data were recorded on an ongoing basis. RESULTS: Mean follow-up was 36.7 months. Eighty-eight percent of patients had a good to excellent aesthetic result. Laterality of reconstruction (bilateral versus unilateral) and radiation history were significant predictors of overall cosmesis. Aesthetic results were not related to preoperative breast size, implant volume, or body mass index. Pathologic capsular contractures (grade III/IV) developed in 10.4 percent of patients. Four percent of all permanent implants were exchanged for a second prosthesis. Ninety-five percent of patients were satisfied with their reconstruction. CONCLUSIONS: Tissue expander/implant reconstruction yields good to excellent long-term aesthetic results in the majority of patients, and overall patient satisfaction remains high. Bilateral reconstructions have higher overall aesthetic grades. Reconstruction may be performed in patients with larger-volume breasts with satisfactory cosmesis. Successful outcomes are possible in patients who receive chest wall irradiation.

Determinants of aesthetic satisfaction following TRAM and implant breast reconstruction.

INTRODUCTION: Several studies have evaluated patient satisfaction following breast reconstruction with the transverse rectus abdominis myocutaneous (TRAM) flap and tissue expander/implant. However, the specific aesthetic determinants of patient satisfaction have not been determined. METHODS: Patients who had undergone tissue expander/implant or TRAM flap reconstruction were retrospectively polled on their age, type and timing of reconstruction, mastectomy type, laterality of reconstruction, adjuvant therapy, and symmetrizing and nipple-areolar procedures. Aesthetic satisfaction based on breast shape, symmetry of breast shape, breast size, symmetry of breast size, breast scarring, and breast sensation was assessed using a 5-point scale. RESULTS: Two hundred eleven patients with 105 TRAM flaps and 160 expander/implants responded. Unilateral TRAM recipients rated their breast shape, symmetry of breast shape, and symmetry of breast volume significantly higher than did implant patients. When bilateral reconstruction patients were evaluated, no significant differences were seen. The presence of nipple-areolar reconstruction positively influenced every parameter except breast sensation. Immediate reconstruction, skin-sparing mastectomy, and age >60 years at the time of reconstruction were also associated with higher scores, while postoperative radiation therapy resulted in lower satisfaction. Free flap reconstruction produced higher satisfaction in breast shape and breast scarring when compared with pedicle flap reconstruction. CONCLUSIONS: Aesthetic satisfaction after breast reconstruction is highly influenced by the presence of nipple-areolar reconstruction and less so by age, timing of reconstruction, adjuvant therapy, or free flap procedures. The type of reconstructive procedure is a significant variable only in unilateral reconstruction.

Mammary reconstruction using tissue expander and partial detachment of the pectoralis major muscle to expand the lower breast quadrants.

The techniques commonly used in breast reconstruction with tissue expanders do not provide a good definition of the lower breast quadrant. With the authors technique a better profile of the breast is achieved. Partial detachment of the pectoral muscle is performed, suturing it to the lower skin flap and thereby avoiding cranial migration of the expander. In addition a rounded shape of the lower quadrants is achieved and the expander remains in a subcutaneous position.

Retrospective case review of capsular contracture after two-stage breast reconstruction: is colonization of the tissue expander pocket associated with subsequent implant capsular contracture?

Periprosthetic capsular contracture is a common problem associated with implant-based breast reconstruction. The purpose of this study was to determine if bacterial colonization of the tissue expander contributes to contracture of the permanent implant. Medical records were reviewed for 86 patients (124 tissue expanders) between 1997 and 2001 in 1 institution. Three specimens taken from the expander were cultured. The overall incidence of colonization was 42.7%; 49.4% (38.8-60.0) of immediate and 28.2% (14.1-42.3) of delayed expanders had at least 1 positive culture site (P = 0.043). The most common organisms were Propionibacterium acnes (57.6%), Staphylococcus epidermidis (31.0%), and Peptostreptococcus (5.8%). Statistical analysis revealed no significant difference between colonization of the expander and capsular contracture of the permanent prosthesis (P = 0.59). 45.8% (25.9-65.8) of breasts irradiated preoperatively developed contracture versus 14% (7.2-20.8) with no irradiation (P = 0.0013). These results suggest that colonization of the expander occurs frequently, irradiation predisposes to contracture, and colonization did not contribute to secondary implant contracture in this study population.

Subincisional muscular coverage of expander implants in immediate breast reconstruction with pectoralis flaps.

Immediate breast reconstruction with expander implants is a safe, simple procedure that allows for a rapid physical and emotional postmastectomy recovery. When complications occur, the patient may be left with a prolonged reconstructive course. Such complications may result from thin mastectomy flaps and resulting marginal skin flap necrosis and implant exposure. Muscle coverage of the implant under the skin incision prevents such marginal necrosis of skin flap from becoming a factor in implant loss. This paper demonstrates a simple method for providing subincisional muscle coverage of expander implants with pectoralis muscle flaps. In this technique, a pocket is developed under the pectoralis muscle. The sternal origin of the pectoralis is released from the midsternal position to its inferior origin. The pectoralis muscle is then rotated inferior-laterally and sutured to the dermis of the underside of the inferior mastectomy skin flap, thereby providing subincisional muscle coverage of the expander implant. During a 5-year period, 42 patients between the ages of 36 and 61 underwent breast reconstruction utilizing this technique. In these patients, there were 4 instances of marginal necrosis. In each of these cases, the implants did not become exposed, and all patients completed the expansion process without significant delay and underwent subsequent implant exchange without incident. Five-year follow-up has shown good esthetic results in all patients.
