title: Complex lower face reconstruction using a combined technique of Estlander flap and subscapular artery system free flaps.
abstract: When advanced mandibular carcinoma is resected, the defect may include lip and oral commissure. Free flap insertion is commonly used to reconstruct the lip defect. Although improvements in the oral reconstructive method via free flap use have been reported, functional and aesthetic results of the oral sphincter remain limited. This case report describes two individuals presenting with massive lower face defects, including a lower lip defect and a mandibular bone defect. Reconstruction was accomplished using the Estlander flap and free subscapular system of flaps. In both cases, the free subscapular artery system flap was elevated from the mandibular bone defect and other mucosal defect. The lower lip and oral commissure defect was reconstructed via Estlander flap. Free flaps survived 100% and both cases healed without complication. Patients regained good oral sphincter function with no reports of drooling. Thus, in cases involving massive lower face resection, including that of the lower lip and mandibular bone, this method of reconstruction when combined with lip-switch flap and subscapular artery system flap can prove to be useful.
