Reverse blood flow as an option in mandibular reconstruction using a two-segment fibula free flap.

Microsurgical reconstruction is currently considered a method of choice for the repair of soft tissue or bony defects in head and neck surgery. This technical note presents the use of a reverse flow technique in mandibular reconstruction with two segments of fibula free flap in a patient with bilateral pseudoarthrosis. In the standard procedure, both segments of the fibula are supplied by one donor vascular pedicle with normal antegrade blood flow. The approach presented here employs reverse flow in the distal segment of the fibula using a venous graft to create two vascular independent free fibula segments. Reverse flow in mandibular reconstruction represents an alternative option to support the success of microsurgical procedures in indicated cases.
