Superficial Musculoaponeurotic System Elevation and Fat Graft Reconstruction After Superficial Parotidectomy

Objective/Hypothesis: Elevation of the superficial musculoaponeurotic system (SMAS) with or without fat graft interposition during superficial parotidectomy prevents a concave facial deformity and Freys syndrome.

The Evolving Etiology of Bilateral Vocal Fold Immobility

In the past, bilateral vocal fold immobility (BVFI) occurred most commonly after thyroidectomy. However, no large series documenting the etiology of adult BVFI has been published within the past fifteen years. This study reviews the etiologic patterns of BVFI at our institutions. We compare BVFI from before and after 1980. We also review combined studies of unilateral vocal fold immobility (UVFI) to compare and unilateral versus bilateral etiologic trends. In comparison with previously published series, fewer cases of BVFI present today as a complication of thyroid surgery and more as the result of malignancies and nonsurgical trauma. Unfortunately, BVFI caused by malignancy is not usually an initial sign of local disease, but an ominous sign of recurrence or metastases. In comparing UVFI and BVFI we found that thyroidectomy causes a higher percentage of BVFI than of UVFI. Over one-third of UVFI cases were caused by neoplasm which further underscores the potential seriousness of immobile vocal folds and the need for careful investigation.

Meta-analysis of Surgical Techniques for Preventing Parotidectomy Sequelae

OBJECTIVE To conduct a meta-analysis of the literature on surgical methods for the prevention of Frey syndrome and concave facial deformity after parotidectomy. METHODS A PubMed search through February 2008 identified more than 60 English-language studies involving surgical techniques for prevention of these parameters. Analyzed works included 15 retrospective or prospective controlled studies reporting quantitative data for all included participants for 1 or more of the measured parameters in patients who had undergone parotidectomy. Report quality was assessed by the strength of taxonomy recommendation (SORT) score. Data were directly extracted from reports and dichotomized into positive and negative outcomes. The statistical significance was then calculated. RESULTS The mean SORT score for all studies was 2.34, and the mean SORT score for all the analyzed studies was 1.88. Meta-analysis for multiple techniques to prevent symptomatic Frey syndrome, positive starch-iodine test results, and contour deformity favored intervention with a cumulative odds ratio (OR) of 3.88 (95% confidence interval [CI], 2.81-5.34); OR, 3.66 (95% CI; 2.32-5.77); and OR, 5.25 (95% CI, 3.57-7.72), respectively. CONCLUSION Meta-analysis of operative techniques to prevent symptomatic Frey syndrome, positive starch-iodine test results, and facial asymmetry suggests that such methods are likely to reduce the incidence of these complications after parotidectomy.

Assessment of Microvascular Anastomosis Training in Otolaryngology Residencies: Survey of United States Program Directors

16 (62%) of the labs were sponsored by otolaryngology departments with 6 (23%) supported by general surgery and the remainder from other sources. Albeit somewhat smaller than human vessels (0.5-1.0 mm vs. 1.95-2.95mm average inner diameters), rat femoral vessels are most commonly employed in training techniques. Thus, while providing the optimum tactile replication, rat vessels prove to be a formidable and challenging training model.

Avoiding secondary skin graft donor site morbidity in the fibula free flap harvest.

OBJECTIVE To compare donor site morbidity in patients who have undergone fibula free flap reconstruction in which the skin graft was taken from the expected cutaneous paddle of the fibula with the known complications of the popular technique of obtaining a split-thickness skin graft (STSG) from a secondary donor site. DESIGN Cohort study. SETTING The tertiary care centers at Loma Linda University Medical Center and University of California, Los Angeles, Medical Center. PATIENTS From September 1, 2006, to March 30, 2007, 30 patients underwent fibula free flap harvest by 2 surgeons at separate tertiary care centers. Twenty-one of those procedures took place at the University of California, Los Angeles, and 9 at Loma Linda University. Patients included 15 men (50%) and 15 women (50%), with a mean age of 58 (range, 19-88) years. All 30 patients underwent fibula free flap harvest with a split-thickness skin graft (graft thickness, 0.04 cm), obtained from osteocutaneous paddle using a 5.1-cm-wide dermatome, as well as oral cavity and oropharyngeal reconstruction with the de-epithelialized skin paddle. MAIN OUTCOME MEASURES Measures of donor site morbidity, including graft failure and wound breakdown, and measures of recipient site morbidity, including flap failure, hardware complications, intraoral complications, and the need for additional surgery. RESULTS Of the 30 patients who underwent this procedure, 4 had partial skin graft failures, for a complete skin graft survival of 87%. There were no complete skin graft losses. Regarding the fibula osteocutaneous free flap, there were no complete flap losses, 1 skin paddle necrosis that required debridement, 2 postoperative orocutaneous fistulas, 1 case of infected/extruded hardware, and 1 adhesion formation that required additional surgery for lysis of adhesion and placement of the split-thickness skin graft. CONCLUSIONS The outlined novel technique has similar rates of free flap survival and skin graft take compared with previously described methods. Harvesting the skin graft over the expected osteocutaneous paddle results in decreased lower extremity morbidity by providing equivalent graft tissue for donor site closure and eliminating the morbidity of a secondary donor site. As long as there will not be 2 large opposing grafted surfaces, this technique should be considered when harvesting fibula free flaps for reconstruction of oromandibular resection defects, especially in cancers of the alveolar ridge and floor of the mouth.

Using image guidance tracking during balloon catheter dilation of sinus ostia

inusitis is one of the most common health problemsfacing Americans today. Sinus disease can usually bemanaged medically; however, when it is unresponsive tomedical therapy, surgical intervention may be warranted.Sinus surgery has evolved from destructive, open surgicalprocedures to minimally invasive, mucosal-sparing opera-tions. In the appropriate individual, catheter-based devicesmay be used to open sinus ostia and restore normal functionand drainage while preserving normal mucosal tissue. Al-though there are studies reporting safety and feasibility ofthe technique,

Subcutaneous vs Intramuscular Botulinum Toxin Split-Face Randomized Study

IMPORTANCE Much has been published regarding rejuvenation of the upper face with botulinum toxin A injection; however, the optimal target tissue layer has not been specifically examined. OBJECTIVE To seek a difference between subcutaneous (SC) and intramuscular (IM) administration. DESIGN, SETTING, AND PARTICIPANTS Prospective, randomized study at a tertiary care university facial plastic surgery practice. Nineteen patients who underwent botulinum toxin A treatment to the forehead were randomized so that each patient received IM injection on one side of the face and SC injection on the contralateral side. INTERVENTION Patients were assessed on the basis of eyebrow elevation before treatment, and at 2 weeks, 2 months, and 4 months following injection. Patients also completed a subjective questionnaire examining discomfort during injection, bruising, and tenderness, as well as their perception of their appearance after treatment. MAIN OUTCOME AND MEASURE Eyebrow height measurements between SC and IM techniques. RESULTS There was no difference in eyebrow height measurements between SC and IM techniques (0.00 [95% CI, -0.02 to 0.02]). Patients did report greater discomfort when receiving IM injections compared with SC injections (-0.76 [95% CI, -1.53 to 0.0005]). Patient satisfaction scores did not demonstrate a statistically significant difference between IM and SC techniques when measured on the first and second posttreatment visits; however, there was a trend toward significance on the final follow-up visit. CONCLUSIONS AND RELEVANCE Subcutaneous injection of botulinum toxin A is equally effective in achieving paralysis of the underlying frontalis muscle as IM botulinum toxin A administration. In addition, the SC route may result in less pain to patients receiving botulinum toxin A injection for rejuvenation of the upper face.

Management of Bite Wounds in the Head and Neck

An estimated 50% of people in the United States will incur an animal or human bite wound at least once in their lifetimes. Although the majority of these individuals do not seek medical attention, bite wounds to the head and neck are a common reason for emergency department visits. Facial bites are complex injuries due to the functional and cosmetic nature of the area, as well as the unique polymicrobial infection potential that exists. We present a review of the epidemiology and microbiology of bite injuries to the head and neck and provide evidence-based recommendations regarding surgical wound closure and antibiotic therapy.

Aesthetic Considerations in Mandibular Reconstruction

As free tissue transfer methods have improved, vascular bone grafting has become state of the art for reconstruction of mandibular defects. Prior studies have focused on flap survival and functional outcomes. The reconstructive surgeon should also strive to attain lofty aesthetic goals for this group of patients. The best results are achieved when patient factors, flap selection, treatment planning, and surgical techniques are all considered and properly selected.
