Cerebrospinal fluid leak associated with proplast implant removal from the temporomandibular joint.

Severe bone erosion within the temporomandibular joint reconstructed with polytetrafluoroethylene implants is a well-recognized phenomenon. Although erosion into the middle cranial fossa has been reported, we know of no report of dural disruption with cerebrospinal fluid leakage. We report a case of cerebrospinal fluid leak noted at the time of PTFE implant removal and its subsequent management. Perforation of the contralateral glenoid fossa and its reconstruction is also reported.
