Chimeric flaps pedicled with the lateral circumflex femoral artery for individualised reconstruction of through-and-through oral and maxillofacial defects.

Reconstruction of through-and-through oral and maxillofacial defects has always been difficult. We have evaluated the feasibility and reconstructive efficacy of chimeric flaps pedicled with the lateral circumflex femoral artery in the reconstruction of 41 through-and-through oral and maxillofacial defects after resections for cancer. There were 29 chimeric anterolateral thigh and anterolateral thigh flaps and 12 chimeric anterolateral thigh and anteromedial thigh flaps, the sizes of which ranged from 5×8 to 9×11 cm. The chimeric flaps provided separate flaps to reconstruct the intraoral mucosa and extraoral skin defects, and 40/41 of them survived. The appearance and function were satisfactory in all patients after the reconstruction. Chimeric flaps pedicled with the lateral circumflex femoral artery are a good choice for the reconstruction of through-and-through oral and maxillofacial defects.
