symphysis menti fracture

Although traditionally the mandible and base of skull are thought to form a complete bony ring, interrupted only by the TMJs.This should mean that the mandible should fracture in two places (akin to the bony pelvis) making single fractures uncommon, but this in fact not the case, with ~40% of fractures being unifocal. 2015 May. Fractures of the symphysis/parasymphysis are inherently unstable. Burm JS, Hansen JE. The symphysis menti grows below into a triangular elevation named mental protuberance.
