Fibular and iliac crest osteomuscular free flap reconstruction of the oral cavity.

A method for reconstruction of oral cavity soft tissues using segmentally or axially supplied free muscle flaps harvested as a unit with their bone components is presented. Both fibular/soleus and iliac crest/internal oblique free flaps are documented, and the pros and cons of each donor site are presented. Twenty-one patients, 17 with cancer or osteoradionecrosis and 4 with benign or congenital conditions of the mandible, have undergone this operation. Ten bone grafts were simultaneously embedded with osseointegrated implants. All free flaps except one survived and resulted in a smoothly mucosalized oral lining. Six patients have had their implants successfully uncovered, all of whom are wearing prostheses. Four other patients are using tissue-borne prostheses. Transfer of free, nonbulky muscle flaps for mucosalized oral soft-tissue reconstruction is feasible in selected patients using first the fibular and, second, the iliac donor site; this soft-tissue technique also contributes to prosthetic dental rehabilitation.
