Objective: To investigate the etiology, clinical manifestations, diagnosis and surgical treatment of persistent cerebrospinal fluid otorrhea. Methods: The clinical data of 26 consecutive patients with cerebrospinal fluid otorhinoma from June 1987 to December 2000 were analyzed. There were 16 males and 10 females. 18 cases of adult children in 8 cases. Results: Fourteen cases of spontaneous cerebrospinal fluid leakage in 26 cases were caused by mastoid and lateral skull base surgery. 15 cases with recurrent meningitis. Twenty-five of 26 cases were successfully surgically repaired in one operation in our hospital, and one case of cerebrospinal fluid rhinorrhea after operation of acoustic neuroma was successfully surgically repaired. Conclusion: Surgery is the main treatment method. During the operation, attention should be paid to the repair of the skull base, especially for the treatment of important parts of the internal auditory canal, tympanic cavity, eustachian tube and mastoid to prevent postoperative cerebrospinal fluid otorrhea.
