Extracranial repair of cerebrospinal fluid otorhinorrhea

Forty-eight patients with cerebrospinal fluid leaks comprise this retrospective study. There were 39 traumatic and 9 spontaneous leaks. Nine patients were initially managed with bed rest and spinal drainage, but 3 patients in this group ultimately required surgical intervention for repair of their persistent leaks. Thirty-nine patients had surgery as initial therapy, with 33 extracranial repairs, 2 intracranial repairs, and 4 combined approaches. The extracranial approach was used in 36 of 42 patients, with an initial success rate of 86%.
