Mandible reconstruction with microvascular surgery.

Microvascular surgery has become the preferred method for mandible reconstruction. Whenever possible, immediate reconstruction at the time of segmental mandible resection will provide the best aesthetic and functional result. Four donor sites (fibula, iliac crest, radial forearm, and scapula) have become the primary sources of vascularized bone and soft tissue for the reconstruction. The fibula has multiple advantages, including bone length and thickness, donor site location permitting flap harvest simultaneously with tumor resection, and minimal donor site morbidity. The fibula donor site should be the first choice for most defects, particularly those with anterior or large bony defects requiring multiple osteotomies. Use of an alternative donor site is best reserved for cases with large soft tissue and minimal bone requirements. Dental rehabilitation through the use of prostheses and osseointegrated dental implants is an important part of the reconstructive process to optimize aesthetics and function.
