Reconstruction of Extensive Oromandibular Defect With Simultaneous Dual Free Flap Transfer

초록

Complex oromandibular defects are usually too extensive or complex to be reconstructed with a single free flap. In this situation, dual free flaps can provide an adequate amount of tissues and a three-dimensional structure for large composite defects. In our institution, a total of 6 patients underwent immediate dual free-flap reconstruction between December 2013 and February 2020. In all patients, oromandibular defects were reconstructed with a combination of a fibula free flap and a vertical rectus abdominis myocutaneous, anterolateral thigh, or radial forearm free flap. All 6 patients showed tolerable flap status without any major complications, and could transit a diet from a dysphagia diet to a general diet on the final visit. Dual free flaps can be considered an optimal reconstructive option with favorable functional and aesthetic outcomes for complex oromandibular defects involving the bone, oral lining, external skin, or soft tissue.
