A combined infratemporal and posterior fossa approach for the removal of giant glomus tumors and chondrosarcomas

Giant glomus jugulare tumors with a large posterior fossa extension are considered either inoperable or at least requiring of a two-stage operation. Likewise, the surgical approach and treatment for chondrosarcomas of the temporal bone are controversial. We describe a combined approach in which, with the aid of microsurgical and laser techniques, such tumors can be removed in one stage. The surgical approach involves a lateral infratemporal approach combined with a posterior fossa craniectomy. This technique was used in seven cases: five glomus jugulare tumors and two chondrosarcomas. There were no deaths, and surgical morbidity consisted of weakness in the facial nerve in four of these patients and gastrointestinal hemorrhage and respiratory distress syndrome in one patient.
