The buccal fat is an important anatomic structure intimately related to the masticatory muscles, facial nerve, and parotid duct. While anatomically complex, an understanding of its boundaries will allow the surgeon to safely manipulate this structure in reconstructive and aesthetic procedures. Technically, the buccal fat pad is easily accessed and moblized. It does not cause any noticeable defect in the cheek or mouth, and it can be performed in a very short time and without causing complication for the patient. The pedicled BFP graft is more resistant to infection than other kinds of free graft and will result in very success. The buccal fat pad has a satisfactory vascular supply. This property of graft and other properties will allow for the closure of defects that cannot be repaired by conventional procedures. The buccal fat pad exposed through an intraoral and buccal incision, has several clinical applications.
