Trans-Mastoid Management of Temporal Bone Tegmen Defects, Encephaloceles and CSF Leaks

Trans-Mastoid Management of Temporal Bone Tegmen Defects, Encephaloceles and CSF Leaks

A review of records revealed fifteen post-surgical patients who underwent tegmen defect repair from 2009-2012. We reviewed patients’ surgical logs, pre- and postoperative charts, imaging, and billing records. At six to nine months postoperatively, all patients underwent MRI with appropriate sequencing to evaluate the repair site and evidence of residual tegmen defect, encephalocele, or CSF leaks.
