Surgical outcomes in the treatment of temporal bone cerebrospinal fluid leak: A systematic review

Temporal bone cerebrospinal fluid (CSF) leakage may have acquired or spontaneous origin. Acquired temporal bony defects typically comprise traumatic injuries, iatrogenic causes, chronic otitis media with or without cholesteatoma, irradiation, neoplastic invasion of the skull base [1]. Concerning the etiology of spontaneous temporal CSF leaks some authors suggest that small bony defects of the middle fossa tegmen originating from imperfect embryologic development may progressively expand with constant CSF pressure [2].
