DIAGNOSIS AND OPERATIVE REPAIR STRATEGY OF AN UNDERLYING TEGMEN DEFECT PRESENTING WITH SPONTANEOUS OTOGENIC PNEUMOCEPHALUS AFTER VALSALVA MANEUVER

Diagnosis and operative repair strategy of an underlying tegmen defect presenting with spontaneous otogenic pneumocephalus after Valsalva maneuver

Background: The tegmen tympani and mastoideum are insidious locations of bony dehiscence.Large defects may result in encephalocele, cerebrospinal fluid leak, recurrent meningitis, and intracranial abscess.A rare complication is spontaneous otogenic pneumocephalus (SOP).Herein, we describe the clinical course and operative repair strategy of a case
