En Bloc Resection of the Temporal Bone and Temporomandibular Joint for Advanced Temporal Bone Carcinoma

摘要

Advanced skin malignancies involving the temporal bone can involve the temporomandibular joint and glenoid fossa. Many of these tumors can be removed with a lateral temporal bone resection; however, extensive involvement of the glenoid fossa should include an en bloc resection of the temporal bone, glenoid fossa, and condyle. We describe a novel surgical approach that is an extension of a temporal bone resection that includes the glenoid fossa and condyle in an en bloc resection with the temporal bone. This procedure has been performed in 7 patients with advanced carcinoma of the temporal bone involving the glenoid fossa. There were no short-term complications as a result of the surgical approach. The addition of a middle fossa craniotomy and inclusion of the glenoid fossa and condyle as part of an en bloc resection of the temporal bone can be performed safely.
