Anatomical correlation among Bichat’s fat pad with the facial nerve terminal branches

Abstract

Introduction: The buccal fat extraction surgery has been sought by people who aim to reduce facial volume. The buccal fat pad has a complex anatomical correlation among the facial structures. The facial nerve paralysis is one of Bichat’s fat extraction complications which might be temporary or permanent, due to the proximity of those anatomical structures. Methodology: The present article aims to emphasize the anatomical correlation between the buccal fat pad and a few terminal branches of the facial nerve through the human cadaveric dissection. The dissection was performed on three human cadaveric hemifacial to expose the buccal fat pad body and the facial nerve extracranial branches. Results: The zygomatic and buccal terminal branches anatomy of the facial nerve has shown variables in each dissected hemifacial part. However, it has always presented closely related to Bichat’s fat pad. Conclusions: The professional that performs the buccal fat removal surgery must have to have the full knowledge not only about the surgical technique but the anatomical variability of the region, as well.
