Free vascularized lateral femoral cutaneous nerve graft with anterolateral thigh flap for reconstruction of facial nerve defects.

Wide resection of a malignant tumor in the parotid gland often results in loss of a long segment of facial nerve, as well as a soft-tissue defect. With conventional nerve grafts, functional recovery of the facial nerve is poor in cases with risk factors that might inhibit nerve regeneration, such as a history of irradiation and a recipient bed scarred from previous operations. For such cases, a vascularized nerve graft is reported to be more effective than a nonvascularized nerve graft. This paper describes the first successful use of a free vascularized lateral femoral cutaneous nerve graft combined with an anterolateral thigh flap to repair the facial nerve and a soft-tissue defect. This method is technically simple, has minimal donor-site morbidity, and typically results in successful nerve recovery.
