Traumatic herniation of the buccal fat pad: a report of two cases and a review of the literature.

Two cases of injury resulting in traumatic herniation of the buccal fat pad into the oral cavity are described. A review of the literature reveals that almost all reported cases of traumatic herniation of the buccal fat pad occurred in young children. The majority of cases resulted from penetration of the buccal mucosa and buccinator muscle by a foreign object in the mouth. Treatment generally consisted of excision of the mass followed by primary closure.
