Buttock Reconstruction in Sarcoma Surgery: An Esthetic Sigmoidplasty Closure for Large Circular Defects Using Double Opposing Skin Flaps

摘要

Background:Large defects arising from extirpation surgery of buttock sarcomas requiring adjuvant radiotherapy are best closed with flap surgery. The traditional solutions are derived from an approach to pressure sores, which were designed for the ischial, sacral, or trochanteric areas, and have now been adapted for true buttock defects. This invariably destroys the esthetics of the buttock. We describe a novel technique of sigmoidplasty, which preserves most of the esthetic features.
