Small incision nonendoscopic browlift.

PURPOSE: To determine the efficacy of a nonendoscopic brow/forehead lift. METHODS: Case series of 12 patients. Small scalp and upper eyelid blepharoplasty incisions were used to elevate the brows/forehead and perform protractor myectomy. RESULTS: All patients achieved an aesthetically pleasing eyebrow and forehead lift with reduction of vertical and horizontal glabellar creases. Complications included one patient who experienced prolonged ecchymosis after corrugator muscle resection and one patient who had asymmetric lid folds after surgery. The length of follow-up ranged from 9 to 35 months. CONCLUSIONS: The small incision nonendoscopic browlift technique provides a useful alternative to the endoscopic approach.

Early diagnosis of retroperitoneal necrotizing fasciitis.

OBJECTIVE: To report survival of retroperitoneal necrotizing fasciitis in an inmunocompromised patient and to demonstrate early clinical signs that may help in the prompt diagnosis and treatment of this severe infection. DESIGN: Case report and literature review. SETTING: An adult, 18-bed intensive care unit within a university hospital. PATIENT: A 38-yr-old man who had undergone an uncomplicated closed hemorrhoidectomy was readmitted to the hospital on postoperative day 5 for erythema around the hemorrhoidectomy and a dirty brown discharge from the wound. INTERVENTIONS: Early diagnosis of retroperitoneal necrotizing fasciitis, wide and repeated debridement, broad-spectrum antibiotics, and eventual abdominal wall reconstruction. MEASUREMENTS AND MAIN RESULTS: This patient manifested periumbilical and bilateral flank erythema, reminiscent of the pattern of ecchymosis seen in cases of retroperitoneal hemorrhage. The findings demonstrate a variation of Cullen's and Grey Turner's sign, most often found in patients with hemorrhagic pancreatitis. An abdominal radiograph revealed a ground glass appearance with radiolucency outlining the bladder, consistent with retroperitoneal air. The chest radiograph showed mediastinal air extending into the neck. Sharp debridement of the retroperitoneal fat, the right anterior rectus sheath, and the right anterior thigh fascia was required to gain control of the infection. Operative cultures grew a mixed flora with Eschericha coli, beta-hemolytic streptococcus, and Bacteroides fragilis predominating. The hospital course was complicated by hemodynamic instability, renal failure, pneumonia, and a pelvic abscess. The patient ultimately survived and underwent abdominal wall reconstruction with mesh. CONCLUSION: Retroperitoneal necrotizing fasciitis is an uncommon soft tissue infection that is often fatal. Early diagnosis in this case was facilitated by the unique clinical findings of a modified Cullen's and Grey Turner's sign. A review of the limited available literature suggests that survival of retroperitoneal fasciitis is possible with prompt debridement and antibiotic therapy.

Acute traumatic abdominal hernia: case reports.

Traumatic abdominal hernia is a rare injury with most reports documenting only one or two such cases. We describe five cases that were recognized during a 22-year period at a single trauma center. Physical examination often revealed abdominal wall tenderness and ecchymosis, but confirmation of hernia required additional testing in four of five patients. Two patients sustained muscle avulsion from the iliac crest which was likely a result of obesity and high riding seatbelts. In three of the patients a computed tomographic scan of the abdomen was instrumental in making the diagnosis. Surgical repair of the hernia was accomplished in three patients. The other two patients were managed nonsurgically. This report documents that an individualized approach to these patients is appropriate. Diagnosis may be difficult and immediate surgery does not prevent late sequelae. Management guidelines based upon a review of the English language literature on traumatic abdominal wall hernias are presented.

Effects of blast exposure on exercise performance in sheep.

BACKGROUND: The effects of blast on maximal exercise performance were investigated in sheep that were trained to perform maximal exercise. METHODS AND RESULTS: Sheep were fully instrumented for determination of pulmonary and systemic hemodynamics. Blast exposure was administered by using a compressed air driven shock tube that was positioned to primarily produce cardiopulmonary injury. Four levels of exposure were used that were known to produce sublethal injury ranging from little or no grossly observable cardiopulmonary injury (level 1) to confluent ecchymosis of the heart, lung, or both (level 4). We evaluated maximal exercise performance 1 hour after exposure to level 1, level 2, and level 3 and 24 hours after level 3 and level 4. VO2max was not significantly decreased 1 hour after exposure to level 1 but was decreased after exposure to level 2 (29.9%) and level 3 (49.3%). Significant improvement in exercise performance was observed in 24 hours, as VO2max was not significantly decreased 24 hour after level 3. VO2max was decreased 24 hour after level 4 injury (30.8%). CONCLUSION: Cardiovascular data collected during exercise suggested that acute cardiopulmonary injury is responsible for the exercise performance decrement observed 1 hour after exposure and that significant recovery of function is observed 24 hours after blast injury.

Postoperative airway findings after maxillomandibular advancement for obstructive sleep apnea syndrome.

OBJECTIVE: To evaluate the upper airway characteristics in the early postoperative period after maxilomandibular advancement for obstructive sleep apnea syndrome. METHODS: Nasopharyngolaryngoscopy was performed before and 48 hours after surgery on 70 consecutive patients who underwent maxillomandibular advancement for obstructive sleep apnea syndrome. The preoperative and the postoperative evaluations were performed by the same examiner for consistency. RESULTS: Mild to moderate lateral pharyngeal wall edema was identified in 70 consecutive patients. Fourteen patients (20%) had edema as well as ecchymosis involving the pyriform sinus and aryepiglottic fold. Four of these patients (6%) were also noted to have hypopharyngeal hematoma involving the pyriform sinus, aryepiglottic fold, arytenoid, and false vocal cord that partially obstructed the airway. These four patients were closely monitored for 1 to 2 additional days for possible expanding hematoma leading to airway compromise. None of these patients were found to have airway difficulty, and the minimum oxygen saturation was more than 90% throughout the hospitalization. All four patients were discharged uneventfully, and the hematoma resolved completely within 10 days. CONCLUSION: Although postoperative edema was expected after maxillomandibular advancement, hypopharyngeal hematoma was unexpected. Although none of our patients had evidence of airway difficulty, the possibility of an expanding hypopharyngeal hematoma should be considered in patients complaining of breathing difficulty after maxillomandibular advancement surgery.

Telemedicine: teleproctored endoscopic sinus surgery.

OBJECTIVE/HYPOTHESIS: Teleproctored surgery projects a surgeon's expertise to remote locations. The objective of the present study was to evaluate the safety and feasibility of this technique as compared with the current standard of care. STUDY DESIGN: Prospective. METHODS: A study was conducted in a residency training program comparing conventionally proctored endoscopic sinus surgery cases with teleproctored cases, with the faculty surgeon supervising through audiovisual teleconferencing (VTC) in a control room 15 seconds from the operating room. RESULTS: Forty-two control patients (83 sides) and 45 teleproctored patients (83 sides) were evaluated. There were no internal differences between groups regarding extent of polypoid disease, revision status, procedures per case, degree of difficulty, general or local anesthesia, or microdebrider use. There were no cases of visual disturbance, orbital ecchymosis or hematoma, or cerebrospinal fluid leak. Orbital fat herniation and blood loss were equal between groups. Three teleproctored cases required faculty intervention: two for surgical difficulty, one for VTC problems. Teleproctored cases took 3.87 minutes longer per side (28.54 vs. 24.67 min, P <.024), a 16% increase. This was thought to be a result of nuances of VTC proctoring. Residents had a positive learning experience, with nearly full control of the operating suite combined with remote supervision through telepresence. Faculty thought such supervision was safe but had concerns regarding personal skills maintenance. CONCLUSIONS: Teleproctored endoscopic sinus surgery can be safely performed on selected cases with an acceptable increase in time. Teleproctored surgery with remote sites may continue to be safely investigated. Incorporating remote supervision through telepresence into the curriculum of surgical residency training requires further study.

Le Fort fractures without mobility.

The Le Fort fracture without maxillary mobility constitutes 9 percent of maxillary fractures observed over a 3-year period. A high Le Fort (level II or III) injury exists as a one- or two-piece incomplete fracture. The degree of fracture is insufficient to permit mobility of the maxillary alveolus. Frequently, an obvious unilateral zygomatic fracture is present. Physical findings consist of bilateral eyelid ecchymosis and malocclusion. The occlusal disturbance may consist of either crossbite, open bite, maxillary rotation, or lack of proper dental intercuspation. On CT scan, fractures are best demonstrated in the posterior and medial maxillary walls at the Le Fort I level; they are most obvious unilaterally with contralateral fractures that may be subtle. Bilateral maxillary sinus fluid is consistently present on CT. Treatment usually consists of observation and traction elastics but may require mobilization of the fragments followed by open reduction and rigid fixation.

Endoscopic sural nerve harvest in the pediatric patient.

A technique of endoscopic sural nerve harvest was devised to minimize the donor-site scarring in pediatric patients requiring peripheral nerve-grafting procedures. The harvests were performed under tourniquet control using two 2-cm incisions for access at the lateral malleolus and the midcalf. Endoscopic visualization and blunt dissection of the nerve were achieved with a 4-mm Hopkins telescope with 30-degree angled lens (Karl Storz GmbH, Tuttlingen, Germany) stabilized in an Emory retractor and attached to a video camera. The medial sural nerve was divided in the popliteal fossa proximally under endoscopic visualization. The lateral sural nerve was identified and harvested when present. Between June of 1994 and March of 1995, 18 patients underwent 27 sural nerve harvests using the endoscopic technique. Mean patient age was 3.3 years (range 4 to 197 months). Indications for surgery included obstetrical brachial plexus palsy (12), facial palsy (5), and ulnar nerve neuroma (1). Nerve-graft length harvested ranged from 13 to 41 cm. Mean tourniquet time per limb was 92 minutes. No nerve graft injury was noted on examination under the operating microscope. Postoperative pain, swelling, and ecchymosis were minimal. Donorsite scarring has been aesthetically satisfactory to date.

Botulinum toxin A for the treatment of facial hyperkinetic wrinkle lines in Koreans.

There are a number of different causes for facial wrinkle lines, such as aging, gravity, and chronic pulling of mimetic muscles on the face. Among these, pulling by mimetic muscles on the skin not only involves facial expression but also has a great role in forming facial wrinkle lines as a result of repetitive action, such as dynamic or hyperkinetic wrinkle lines. Botulinum toxin A is currently being used for eliminating facial hyperkinetic wrinkles by causing paralysis of the underlying mimetic muscles. Because there are some histologic differences between Asians and Caucasians, such as thick dermis and more abundant collagen fiber, etc., the chronic pulling by mimetic muscles on the skin is expected to affect facial wrinkles differently. Therefore, the purpose of this study was to determine the efficacy of botulinum toxin A injection in eliminating facial hyperkinetic wrinkle lines among Korean patients. This study included 38 patients and 59 injection sessions from January of 1996 to April of 1997. We used Botox containing 100 U. Toxin was diluted with 4 ml of sterile normal saline and yielded 2.5 U for each 0.1 cc. A dose of 5 to 10 U was used in each muscle. Ages ranged from 26 to 56 years. There were 33 women and 5 men included in this study. Thirty-two of the patients were followed from 3 months up to 12 months after injections. The number of injection sessions that were performed on each patient was as follows: one session, 23 patients; two sessions, 10 patients; three sessions, 4 patients; four sessions, 1 patient. The number of injections per target site among these 38 patients was as follows: lateral canthal area, 33; glabellar area, 9; forehead, 9; nasal dorsum, 5. The most common duration of effective response was about 4 months, but in eight patients the period was over 5 months. After the response, complete recovery took about 1 or 2 months. Two patients felt unsatisfied, 5 patients felt slightly improved, and 25 patients retained only a slight line and were satisfied with the results. None of the patients experienced complete removal of wrinkle lines. Adverse effects included altered facial looks or appearances, mild local swelling, and ecchymosis at the injection sites. No systemic side effects were noted. Based on these results, the injection of botulinum toxin A seems to be an effective method of eliminating wrinkle lines on the upper third of the face in Korean patients, and it was a simple and effective nonsurgical procedure.

The lateral osteotomy in rhinoplasty: clinical and radiographic rationale for osteotome selection.

A preferred osteotome for endonasal osteotomy would facilitate reliable, complete osteotomies with minimal soft-tissue trauma. In this report, a radiographic evaluation of the bony lateral nasal wall thickness along the track of a high-low-high osteotomy was undertaken to guide the determination of appropriate osteotome size. Bone window axial computed tomographic scans were evaluated in 56 patients with a mean age of 48 years (range, 19 to 86 years). The average thickness along the site of lateral osteotomy was determined to be 2.47 mm (standard deviation, 0.47) in male patients and 2.29 mm (standard deviation, 0.40) in female patients. On the basis of these data, clinical evaluation of prototype 3- and 2.5-mm low-profile guarded osteotomes was undertaken in comparison with a "standard" 4-mm low-profile guarded osteotome to assess both their reliability and the degree of intranasal trauma, as reflected by intranasal mucosal tears. Although 2- and 3-mm unguarded osteotomes are time-tested, they may be reliable only in the hands of the most experienced surgeons. Therefore, a low-profile guard was included in the osteotome design to allow the surgeon to engage the bone securely and minimize the risk of slippage. Forty patients underwent rhinoplasty, for a total of 80 lateral osteotomies; the mean age of the patients was 38 (range, 16 to 75). In all cases, lateral osteotomies were accomplished with one pass. The 4-mm osteotome causes intranasal mucosal tears in 95 percent of osteotomies, the 3-mm osteotome in 34 percent, and the 2.5-mm in 4 percent. Early postoperative edema and ecchymosis were comparable among the groups. One patient, who underwent osteotomies with a 4-mm osteotome, had excessive postoperative narrowing, possibly due to his wearing of eyeglasses earlier than directed. This report suggests that proper selection of osteotome and attention to proper surgical technique results in a reliable, minimally traumatic lateral osteotomy through the endonasal approach. The 2.5-mm osteotome was reliable and the least traumatic to soft tissue of the osteotomes evaluated.

Reduction of lower palpebral bulge by plicating attenuated orbital septa: a technical modification in cosmetic blepharoplasty.

Bulging of the lower eyelid is regarded as a sign of aging. "Herniation" of the periorbital fat pads is traditionally regarded as the factor responsible for the change. Excision of fat pads, therefore, has been the mainstay of treatment in reducing the palpebral bulge in cosmetic blepharoplasty. The surgical excision of"excess" and "herniated" fat pads, however, causes problems such as lid ecchymosis, chemosis, lid contour irregularity, ectropion, and retrobulbar hematoma formation. The author proposes that the loss of fat pad support caused by the attenuation of the orbital septa, not herniation of the excess fat pads, is the major factor responsible for the bulge. The author further proposes that the functional integrity of the orbital septum can be restored by plicating the attenuated orbital septa with 5-0 absorbable sutures. This technique of invaginating the protruded fat pad was performed in 138 individuals (276 lower eyelids). The operation was technically simple, and the approach was "tissue friendly." The results obtained, with the exception of a mild degree of puffiness encountered soon after the surgery, were satisfactory. Morbidity was minimal.

A current 10-year retrospective survey of 199 surgically treated orbital floor fractures in a nonurban tertiary care center.

This study characterizes the surgically treated patient population suffering from orbital floor fractures by use of current data from a large series consisting of 199 cases taken from a nonurban setting. Data were gathered through a retrospective chart review of patients surgically treated for orbital floor fractures at the University of Michigan Health System, collected over a 10-year period. Data regarding patient demographics, signs and symptoms of presentation, cause of injury, nature of injury, associated facial fractures, ocular injury, and associated nonfacial skeleton trauma were collected. In total, there were 199 cases of orbital floor fractures among 189 patients. Male patients outnumbered female patients by a 2:1 ratio and were found to engage in a wider range of behaviors that resulted in orbital floor fractures. Motor vehicle accidents were the leading cause of orbital floor fractures, followed by physical assault and sports-related mechanisms. The ratio of impure to pure orbital floor fracture was 3:1. The most common signs and symptoms associated with orbital floor fractures, in descending order, were periorbital ecchymosis, diplopia, subconjunctival hemorrhage, and enophthalmos. Associated facial fractures were found in 77.2 percent of patients, the most prevalent of which was the zygoma-malar fracture. Serious ocular injury occurred in 19.6 percent of patients, with globe rupture being the most prevalent, accounting for 40.5 percent of those injuries. There was a 38.1 percent occurrence of associated nonfacial skeletal trauma; skull fracture and intracranial injury were the most prevalent manifestations. Associated cervical-spine fractures were rare (0.5 percent). Statistical examination, using odds ratios and chi-squared analysis, demonstrated significant associations that have not previously been reported. Impure and pure orbital floor fractures revealed striking differences in several demographic aspects, including mechanism of injury, signs and symptoms of presentation, spectrum of associated trauma, and the severity of concomitant trauma.

Personal experiences and algorithm of endoscopically assisted subperiosteal face lift in orientals for 5 years.

Orientals are anatomically distinct from Caucasians and are characterized by a thick dermis, a Mongoloid slant of the palpebral fissure, a relatively prominent zygoma and mandible angle, and a relatively flat nose. Given these characteristics, it was believed that the subperiosteal face lift was not suitable for Orientals. However, at our institution, endoscopically assisted subperiosteal face lifts were performed from May of 1994 to October of 1998 on 236 patients; variable pitfalls, as well as satisfying results, were reported. Patient ages ranged from 29 to 66 years (mean age, 55.2 years), and follow-up ranged from 6 to 44 months (mean follow-up, 23 months). All forehead and brow lifts were performed using an endoscopic guide, and routine corrugator resections and procerus myotomies were performed. Three slanted cortical tunnels were made at the corresponding locations on the outer table of the calvarium, and 1-0 nylon or screw suspension and fixation were performed after a 1-cm to 2-cm lift. Midface lifts were performed through lower blepharoplasty incisions and vertical temporal incisions instead of through conventional preauricular and postauricular incisions. Dissections were made subperiosteally and over the deep layers of deep temporal fascia. Malar fat pads were suspended with 1-0 nylon and affixed to deep temporal fascia. Most patients have been satisfied with their postoperative results, but unfavorable results and complications have been reported. Complications were classified as early or late complications or unfavorable results on the basis of the 3-week postoperative evaluation. There were 28 early complications (11.9 percent), consisting of ecchymosis with edema (persisting for up to 4 weeks), paresthesia, lagophthalmos, accentuated Mongoloid slant, small dimpling on the scalp, and scalp fold formation on the fixation site. There were 13 late complications/unfavorable results (5.5 percent), consisting of insufficient lift, exaggeration of sunken upper eyelids, intermittent headaches, itching sensations, and paresthesia on the scalp. The unfavorable results occurred in the patients who had previously undergone blepharoplasty and in those who had a history of foreign body injections into the face, fatty and thick faces, sunken upper eyelids, Mongoloid slants, and asymmetric facial expressions. Through understanding the anatomic characteristics of the Oriental face (i.e., thick dermis, Mongoloid slant of palpebral fissure, prominent zygoma and mandible angle, and flat nose), satisfying results were achieved by appropriate application of the modified procedures.

Blindness as a complication of Le Fort I osteotomy for maxillary distraction.

High Le Fort I osteotomy and maxillary distraction has become an accepted method for the treatment of maxillary retrusion in children and teenagers with cleft lip and palate or craniofacial anomalies. This procedure effectively corrects the dentofacial deformity in these patients. No major surgical morbidity has been reported. During the past 4 years, 94 cleft patients with maxillary hypoplasia received Le Fort I osteotomy and distraction osteogenesis at the authors' center. Two of them developed blindness after this operation. The first case was a girl with bilateral cleft lip and palate with median facial dysplasia. She received high Le Fort I osteotomy at age 12 years 4 months to correct maxillary retrusion. Right eye swelling and ecchymosis was found after surgery. The patient complained of vision loss in that eye 2 days later. Computed tomography showed subarachnoid hemorrhage and skull base hematoma. There were no atypical fractures in the orbit, pterygoid plates, sphenoid bone, and skull base. Angiogram revealed left ophthalmic and basilar artery aneurysm. The second case was a 12-year-old boy with left cleft lip and palate. He received Le Fort I osteotomy to correct maxillary retrusion. During surgery, abnormal pupil dilatation was found after the osteotomy and down-fracture of maxilla. Emergent computed tomography found no hemorrhage or atypical fractures. Examination revealed complete left optic neuropathy and partial right abducens nerve palsy with mydriasis. Magnetic resonance imaging, magnetic resonance angiography, and repeated computed tomography revealed no sign of orbital injury, vascular problem, or abnormal fractures. The cause of blindness was unknown. In both cases, a steroid was used. Maxillary distraction was continued. Recovery of meaningful visual sense did not occur after 3 and 2 years' follow-up, respectively. A review of the literature revealed five other patients who suffered from visual loss after Le Fort I osteotomy. Inadvertent skull base fractures were identified in two cases, but a cause for the blindness was not known in the others. Induced hypotension and indirect trauma may be responsible for the optic nerve injury. In none of the cases was meaningful visual sense recovered, although high-dose steroids were given. In conclusion, a total of seven cases developed blindness after Le Fort I osteotomy. Once blindness develops, the prognosis is poor. High Le Fort I osteotomy should be performed with extreme care, and perhaps the informed consent should include visual loss as a complication of the procedure.

Rattlesnake bite complications in 19 children.

The Western diamondback rattlesnake, Crotalus atrox, is responsible for the majority of snakebites in Sonora, Mexico. We report 19 cases of children who were attacked by these snakes. Most of the rattlesnake attacks occurred in rural areas during the summer. The children's ages ranged from one to 15 years. The lower extremities, especially the legs, were most often bitten. The signs and symptoms presented by these patients included: pain, edema, limitation of motion, ecchymosis, bleeding and necrosis in the area of the bite, epistaxis, hematuria, and vomiting. Hospital treatment included: parenteral electrolyte solutions, antivenom serum, antibiotics, tetanus toxoid, blood transfusions, hydrocortisone, heparin, and peritoneal dialysis. In one case a fasciotomy was necessary. The observed complications on envenomations included: hemolysis, local necrosis, coagulation disorders, paresthesia, somnolence, and acute renal failure. One death occurred from disseminated intravascular coagulation.
