A patient with platybasia of the skull and temporomandibular joint ankylosis is presented. Relief of brain stem compression by the impingement of the odontoid through a soft, hypoplastic clivus was done by first doing a mandibular condylectomy to open the mouth. A transoral-transpharyngeal route was then employed to excise the odontoid process.
