A review of the gross anatomy, functions, pathology, and clinical uses of the buccal fat pad.

The buccal fat pad is a trigone-shaped adipose tissue located in the cheek that assumes numerous functional and aesthetic clinical uses. It has been studied extensively within the past four decades, and its use in repairing common and debilitating oral defects is the motive for continued research on this topic. It is vital to understand the etiology of any oral defect or of a lesion of the buccal fat pad, for a misdiagnosis can prevent effective treatment of the underlying problem. In this review, we describe the embryology and anatomy of the buccal fat and its association with clinical condition and clinical procedures.
