title: Combined Middle Cranial Fossa and Trans-Mastoid Approach for the Management of Post-Mastoidectomy CSF Otorrhoea.
abstract: Cerebrospinal fluid (CSF) otorrhoea is an uncommon condition arising from defects in the tegmen and middle cranial fossa. 33 year gentleman presented with post-mastoidectomy CSF otorrhoea of 5 year duration. Imaging finding were suggestive of fracture in the tegmen region. A combined middle cranial fossa/transmastoid was used to repair the defect. Defect was identified in the tegmen plate and it was closed with pedicled pericranial graft, laterally based pedicled temporalis muscle graft reinforced by bone dust and supported with intact mucosal flap. The leak stopped completely following surgery. The patient is doing well at follow up. Repair of these defects need careful analysis of imaging findings to understand pathological anatomy, and a well planned surgical approach to achieve meticulous repair.
