Posttraumatic extracapsular temporomandibular bony ankylosis between the coronoid process and base of the skull. Report of a case.
Extracapsular temporomandibular bony ankylosis between the coronoid process and the base of the skull but not involving the zygomatic arch is very uncommon. We have presented such a case, which developed secondary to heterotopic bone formation following trauma. Treatment consisted of ostectomy between the sigmoid notch and the base of the skull.
