BACKGROUND: Perforator flaps allow the transfer of the patient's own skin and fat in a reliable manner with minimal donor-site morbidity. The deep inferior epigastric artery (DIEP) and superficial inferior epigastric artery (SIEA) flaps transfer the same tissue from the abdomen to the chest for breast reconstruction as the TRAM flap without sacrificing the rectus muscle or fascia. Gluteal artery perforator (GAP) flaps allow transfer of tissue from the buttock, also with minimal donor-site morbidity. INDICATIONS: Most women requiring tissue transfer to the chest for breast reconstruction or other reasons are candidates for perforator flaps. Absolute contraindications to perforator flap breast reconstruction include history of previous liposuction of the donor site or active smoking (within 1 month prior to surgery). ANATOMY AND TECHNIQUE: The DIEP flap is supplied by intramuscular perforators from the deep inferior epigastric artery and vein. The SIEA flap is based on the SIEA and vein, which arise from the common femoral artery and saphenous bulb. GAP flaps are based on perforators from either the superior or inferior gluteal artery. During flap harvest, these perforators are meticulously dissected free from the surrounding muscle which is spread in the direction of the muscle fibers and preserved intact. The pedicle is anastomosed to recipient vessels in the chest and the donor site is closed without the use of mesh or other materials. CONCLUSIONS: Perforator flaps allow the safe and reliable transfer of abdominal tissue for breast reconstruction

BACKGROUND: Despite the advances in cleft palate closure over the past 20 years, postoperative fistulas are still a significant problem. Fistula rates average 10 to 23 percent, and it has been suggested that wide clefts have a higher rate of fistula formation. METHODS: In an attempt to improve closure rates, the authors placed decellularized dermal graft within the closure of 31 consecutive palatal cleft closures using the Furlow technique, with one attending surgeon. A retrospective review of this series of patients was analyzed for cleft width, Veau type, and rate of healing. RESULTS: Average cleft width was 12.2 mm (range, 8 to 15 mm). There were one Veau type I, five Veau type II, 20 Veau type III, and six Veau type IV patients. The average age at time of palate repair was 11.75 months (range, 8 to 28 months). One patient (Veau type IV, 15-mm width) developed fistula (3.2 percent fistula rate overall). There was no evidence of rejection, scarring, or impaired palatal motion by examination. CONCLUSIONS: A low fistula rate was obtained in Furlow technique palatal cleft repairs using decellularized dermis when compared with historical controls. Decellularized dermis may provide an additional barrier to wound breakdown in the postoperative period and may improve fistula rate

We present a 26-year-old patient with juvenile-onset arthritis, Alagille's syndrome, micrognathia, and progressive sleep apnea. Despite the presence of significant temporomandibular joint pathology, mandibular distraction was indicated to correct life-threatening sleep apnea. Before distraction, the patient had only 10 mm of maximal interincisal opening and bilateral temporomandibular joint symptomatology. After distraction, the patient's sleep apnea resolved. There was slight improvement in her maximal incisal opening (12 mm) with neither exacerbation nor improvement of her temporomandibular joint symptomatology

BACKGROUND: Shoulder stabilization is of utmost importance in upper extremity reanimation following paralysis from devastating brachial plexus injuries. The purpose of this report is to present the authors' experience with suprascapular nerve reconstruction in 118 cases of adult brachial plexus lesions. Outcomes were analyzed in relation to various factors, including patient age, denervation time, donor nerve used, and functional restoration achieved in the supraspinatus versus the infraspinatus muscles. METHODS: The medical records of 118 adult patients operated on by a single surgeon between 1978 and 2002 who had suprascapular nerve reconstruction were reviewed; 102 patients had adequate follow-up. Direct neurotization of the suprascapular nerve was carried out in 78 patients, while in 40 patients, interposition nerve grafts were used. In 80 patients, the distal spinal accessory was used as the motor donor nerve for suprascapular nerve neurotization, while in 10 patients, other extraplexus motor donors were used. In 28 patients, intraplexus motor donors were used to reinnervate the suprascapular nerve. RESULTS: Results were good or excellent in 79 percent of the patients for the supraspinatus muscle and in 55 percent for the infraspinatus. There was a statistically significant difference between direct spinal accessory to suprascapular nerve neurotization and accessory to suprascapular via a nerve graft. Early surgery and less than 6 months of denervation time yielded significantly better results than late surgery and more than 6 months of delay in the treatment. CONCLUSIONS: Suprascapular nerve neurotization is a high priority in upper limb reanimation for restoration of glenohumeral joint stability, shoulder abduction, and external rotation. Concomitant neurotization of the axillary nerve yields improved outcomes in shoulder abduction function. The best results are seen when direct neurotization of the suprascapular nerve is performed within 6 months from the injury

PURPOSE: The aim of this study was to review and describe techniques for the reconstruction of large, complex perioral defects after resection of oral squamous cell carcinoma with emphasis on cosmetic and functional outcome. PATIENTS AND METHODS: A review of techniques and selected case presentations using different flap designs for the reconstruction of large perioral defects following resection of squamous cell carcinoma was performed. The Bernard and Karapandzic flaps were used for large lower lip defects. A Zisser flap technique was used to reconstruct a large commissure defect. RESULTS: All reconstructed patients had acceptable functional results and healed without complication. The large lower lip defects were easily closed with the Bernard and Karapandzic flaps. The commissure defect was reconstructed using the Zisser technique. While cosmesis was acceptable in all cases, the commissure was the most difficult region to reconstruct with a favorable appearance. There were no flap failures. The Karapandzic flap led to greater rounding of the commissure area and the composite resection resulted in a lack of lower lip support that was improved with prosthesis. Function was noted to be excellent in the Bernard and Karapandzic flaps, with the patients able to purse lips and blow up balloon-type devices. CONCLUSION: The Bernard, Karapandzic, and Zisser flaps provide a predictable method to reconstruct large perioral defects following resection for oral cancer. Subsequent fabrication of a prosthesis can aid in lip support for the resected area

The purpose of this paper was to examine the geographic distribution of New York City adults aged 65 and older by race/ethnicity and poverty status. Also analyzed was seniors' access to dental care as defined by the location of dental providers and their proximity to the subway system lines in Manhattan and the Bronx. ArcGIS software was used to create a geographic information system (GIS) incorporating relevant data from a variety of sources. Individual and overlay maps were then produced to examine the aims of this analysis. Data showed that Black race, Hispanic ethnicity, and poverty status tend to co-occur spatially among seniors in Northern Manhattan and the South Bronx. Further, a spatial/transportation barrier may inhibit access to dental care for seniors who reside in these areas. By presenting multiple layers of local information juxtaposed, GIS can help provide directions for planning oral health service delivery for seniors

To examine the association between body mass index (BMI) percentile and asthma in children 2-11 years of age, we performed a cross-sectional analysis of 853 Black and Hispanic children from a community-based sample of 2- to 11-year olds with measured heights and weights screened for asthma by the Harlem Children's Zone Asthma Initiative. Current asthma was defined as parent/guardian-reported diagnosis of asthma and asthma-related symptoms or emergency care in the previous 12 months. Among girls, asthma prevalence increased approximately linearly with increasing body mass index (BMI) percentile, from a low of 12.0% among underweight girls (BMI </=5th percentile) to a high of 33.3% among girls at risk for overweight (BMI 85th-94th percentile). Among boys, asthma prevalence was associated in a U-shaped curve with the extremes of BMI percentile, that is, 36.4% among underweight boys, 19.1% among normal weight boys (BMI 6th-84th percentile), and 34.8% among overweight boys (>95th percentile). After adjusting for age, race/ethnicity, and household smoking, among girls, having asthma was associated with being at risk for overweight (odds ratio [OR], 2.6; 95% confidence interval [CI], 1.4-5.0) and being overweight (OR, 2.1; 95% CI, 1.2-3.8) compared to normal weight; among boys, having asthma was associated both with overweight (OR, 2.4; 95% CI, 1.4-4.3) and with underweight (OR, 2.9; 95% CI, 1.1-7.7). Large, prospective studies that include very young children are needed to further explore the observed association between underweight and asthma among boys. Early interventions that concomitantly address asthma and weight gain are needed among pre-school and school-aged children
