Management of Limited Mouth Opening After Open Reduction and Fixation of Mandibular Coronoid Fractures.

Abstract

Mandibular coronoid process fractures are relatively rare and generally treated conservatively. This paper reports a case of limited mouth opening and pain after open reduction and fixation of the mandibular coronoid fracture. After the loose titanium screws, plates, and absorbed coronoid fracture fragments were removed, the patient's mouth opening was restored immediately. The authors believe that open reduction and fixation for coronoid process fractures can cause postoperative limited mouth opening and pain. Conservative treatment of coronoid process fractures is more beneficial for patients.
