A staged approach to oromandibular reconstruction using the iliac crest free flap in the setting of bilateral failed fibula free flaps.

[BACKGROUND] While a single-stage free-flap reconstruction is the preferred approach for oromandibular defects, a multistaged approach may be necessary in rare cases. These patients can still be effectively restored with functional and aesthetic improvements.

[METHODS] We report two cases with a history of bilateral failed fibula free flaps. We detail the multistaged reconstruction to repair these complex defects and discuss the considerations when planning such procedures.

[RESULTS] Both patients successfully underwent a staged reconstruction with an iliac crest osteocutaneous flap following either a rectus abdominis or pectoralis major myocutaneous flap.

[CONCLUSION] Oromandibular reconstruction is an expected outcome in the contemporary management of oral cavity cancer and osteoradionecrosis. However, complications do occur and can be devastating. In cases of bilateral failed fibula free flaps, a staged approach is a favorable option. Moreover, the iliac crest provides an important reconstructive option with the documented potential for implant born dental rehabilitation.
