Nomenclature and structure
The buccal fat pad is composed of several parts, although exactly how many parts seems to be a point of disagreement and no single consistent nomenclature of these parts has been observed. It was described as being divided into three lobes, the anterior, intermediate, and posterior, “according to the structure of the lobar envelopes, the formation of ligaments, and the source of the nutritional vessels”.[1] Also, there are four extensions from the body of the buccal fat pad: the sublevator, the melolabial, the buccal, and the pterygoid. The nomenclature of these extensions derives from their location and proximal muscles.[4]
The anterior lobe of the buccal fat surrounds the
Function
Some people describe the buccal fat pad’s primary function in relation to chewing and suckling, especially in infants. This theory derives some support from the loss of volume to the intermediate lobe, which would be most directly involved in chewing and sucking, from infancy to adulthood.
Another proposed function is as gliding pads that facilitate the action of the muscles of mastication.[1]
The buccal fat pad may also function as a cushion to protect sensitive facial muscles from injury due to muscle action or exterior force.[1]
Clinical uses
The buccal fat pad is commonly used in facial recontouring. Several authors discuss the importance of the buccal fat pad in attaining good results from a facelift.[2][5][6][7]
Buccal flaps (not always including the buccal fat pad) are used in reconstruction of the periorbital area after injury.
Removal of the buccal fat pad is also sometimes used to reduce cheek prominence, although this procedure may carry with it a significant risk of damage to the buccal branch of the facial nerve and the parotid ducts.[12]
