Objective: To describe surgical procedures, previous failed pregnancies, methods for overcoming pregnancy failure and, most importantly, birth of a healthy infant, in uterus transplantation from deceased donor. Background: Majority transplants have involved live donors, but several advantages make donor practicable option, principally by eliminating risks to the Methods: Uterus was performed September 2011 Turkey. After 5 miscarriages, perfusion computed tomography revealed an obstructed...

Face transplantation is a viable reconstructive approach for severe craniofacial defects. Despite the evolution witnessed in field, ethical aspects, clinical and psychosocial implications, public perception, economic sustainability remain subject of debate unanswered questions. Furthermore, poor data reporting sharing, absence standardized metrics outcome evaluation, lack consensus definitions success failure have hampered development "transplantation culture" on global scale. We completed...

The purpose of this study was to report the motor functional outcomes and sensory recovery patients who had undergone total or subtotal glossectomy for oral squamous cell carcinomas reconstructed with chimeric anterolateral thigh (ALT) flaps.Six patients, 4 men 2 women, a mean age 49.5 years (range, 36-73 years) were included in study. All treated ALT, including vastus lateralis muscle its nerve skin paddle innervating nerve. administered tests involving recovery, intelligibility,...

The ideal reconstructive method for the palatal defect should provide durable, stable coverage, and a natural contour, while simultaneously minimizing morbidity of both donor sites. Although small usual defects can be repaired easily using local adjacent tissues, successful closure large, complex is still challenging problem. Numerous free tissue options have to date been described large defects. radial forearm flap constitutes good option goals, sacrifice major artery hand skin graft with...
