Use of the Facial Artery Based Buccinator Musculo-Mucosal Island Flap for Reconstruction the Upper Vestibule: A Case Report

This article presents a documented case of upper vestibular reconstruction using a musculomucosal buccinator flap focused on the facial artery. This is an 80-year-old patient who presented with an ulceration in the labio-naso-jugal region. The biopsy revealed that it was a sclerodermiform basal cell carcinoma. Surgical excision was performed, leaving an extensive multi-tissue loss of substance (mucosa, muscularis and cutaneous). This required first the reconstruction of the vestibular defect by FAMM flap then reconstruction by a frontal flap. The procedure allowed a satisfactory functional and aesthetic reconstruction, without major complications at the donor site or the reconstructed area. The objective of the study is to describe the harvesting technique and to demonstrate the efficacy, versatility and ease of use of the FAMM flap in reconstructions requiring good mucosal compatibility, while limiting complications.
