Pelvic and Perineal Reconstruction.

[LEARNING OBJECTIVES] After studying this article, the participant should be able to: 1. Classify types of bony pelvic resections. 2. Outline reconstructive options for pelvic and perineal defects. 3. Identify advantages and drawbacks of various reconstructive techniques. 4. Recognize the functional benefits of bony and soft-tissue reconstruction.

[SUMMARY] Defects of the pelvis and perineum arise from tumors, trauma, infection, congenital differences, and gender incongruence. Pelvic resections can result in bony instability and soft-tissue deficiency. The goals of reconstruction are maintenance of spinopelvic continuity, elimination of dead space, resurfacing of cutaneous defects, and prevention of hernias. Perineal reconstruction has important functional considerations. Abdominoperineal resection and pelvic exenteration defects benefit from flap reconstruction to decrease pelvic wound complications. Vulvovaginal reconstruction is performed with flaps from the perineum, thigh, or abdomen. Scrotal and superficial penile defects are most commonly reconstructed with scrotal flaps and skin grafts. Total penile reconstruction most commonly uses a radial forearm free flap.
