Abstract

BACKGROUND: Lateral temporal bone encephaloceles incidence is increasing with obesity rates. Middle fossa (MF) craniotomy, transmastoid (TM), or combined MF + TM access can be used for repair.

METHODS: Retrospective review of MF or MF + TM repair with an intradural graft. Sex, age, and body mass index (BMI) were collected. Pre/postoperative audiometric results were included. Postoperative complications were reported.

RESULTS: A total of 49 patients (50 repairs) were included. In addition, 74% were women (

CONCLUSION: Intradural repair of encephalocele and CSF leak is a safe and effective surgical approach. Intradural reinforcement along the entire MF floor is beneficial for multiple areas of dehiscence and thin dura. Complication rates including recurrent/persistent CSF leak and aphasia related to temporal lobe retraction were similar to previously published reports and not associated with older patient age. Hearing was stable or improved in 94% with no difference noted between MF and MF + TM repair.
