Conservative Management of the Isolated Mandibular Coronoid Process Fracture

Abstract

Fractures of the coronoid process are uncommon and can easily be missed. Coronoid fracture may manifest as simple, linear line with minimal displacement. If the periosteum is traumatized, the degree of displacement may increase. Restricted mouth opening and mandibular movement, malocclusion, and swelling below the zygomatic arch may be evident. The decision of treatment plan should be based on the fracture pattern, time of the fracture, the presence or absence of concomitant fractures, and clinical symptoms. Coronoid fractures are generally managed conservatively, a few cases require surgical intervention. A rare case of fracture of the coronoid process caused by trauma of the temporalis muscle is described.
