The Middle Cranial Fossa Approach in Managing Lesions of the Temporomandibular Joint

Abstract

The temporomandibular joint (TMS) lies at the skull base. Its bony roof forins part of the floor of the middle cranial fossa. It is bounded by the infratemporal fossa, external auditory canal, middle ear, and eustachian tube. When wide resection of tumors arising within the TMJ is necessary, skull base approaches permit complete resection with oncologically sound margins. Precise pathologic diagnosis can be difficult and extra care should be taken to ensure diagnostic accuracy. Outcomes are improved if attention and effort is directed to rehabilitation of the TMJ. Five such cases are presented and the literature is reviewed.
