Rowson (1992) attributed poor muscle tone and chronic food inspissation as contributory factors without any defect in buccinators muscle for formation of buccal diverticulum in a very old man.
A novel technique for cheek mucosa defect reconstruction using a pedicled buccal fat pad and buccinators myomucosal island flap.
As hypothesized by Seltzer S, the cutaneous sinus tract occurs when mandibular teeth apices of posterior teeth are anatomically inferior to the origin of buccinators muscle and if the apices are superior to buccinator origin, a buccal sulcus fistula/ more rarely, a lingual perforation might occur, more commonly seen in young individuals (9).
In a naturally occurring dimple, there is a small defect in the muscles of the cheek (typically the buccinators muscle); when a person smiles or makes other facial expressions, the skin overlying this defect is stuck down to the underlying connective tissue and is pulled inward to create a dimple.
There are eight moveable structures that affect the shape of the resonator: the pharyngeal constrictors (the muscles that form the back of the throat), the soft palate (velum) that is suspended between the throat and the nasal passages, the jaw (mandible) along with the muscles that move it, the tongue, the lips, the buccinators (the muscles that form the inside of the cheeks), the larynx along with the muscles that move it, and the balance of the head at the atlanto occipital (A/O) joint.
Indeed, opinion is emerging that posterior-acting forces of the buccinators during bottle-feeding, pacifier-use and digit-sucking oppose forward acting forces of sucking during breast-feeding (9).
