Abstract |
Introduction |
Chondroblastoma is a rare tumor that can involve the temporal bone. Because it is a benign tumor, functional surgery must be proposed. We report a case of a patient with a massive chondroblastoma operated on with preservation of the facial nerve, and description of the surgical technique.
Case presentation |
A 37-year-old man presented with a 9-month history of a growing left pre-auricular mass and hearing loss. Neuroimaging showed an osteolytic mass invading the temporal bone and temporomandibular joint. Excision was performed via a transpetrosal and transcochlear approach with posterior transposition of the facial nerve. EMG monitoring was effective in preventing facial palsy. Four years later, no sign of recurrence was observed.
Discussion |
Chondroblastoma is a locally aggressive tumor, especially when located in the petrous bone and temporomandibular joint. The suggested treatment is a complete excision.
