Abstract:
A patient with spontaneous bilateral fracture of the mandibular coronoid process is presented. The definite cause is unknown, but possible contributing factors include osteoporosis, bruxism and changed kinetics of the temporalis muscle after bilateral sagittal split osteotomy (BSSO) resulting in an avulsion fracture. The patient was treated surgically with bilateral coronoidectomy.
