Abstrakt:	Objective: To study the clinical manifestations and surgical treatment of temporal bone cerebrospinal fluid leakage. Methods: The clinical data of twenty seven cases with temporal bone cerebrospinal fluid leakage were analyzed retrospectively. Different surgical procedures were adopted according to the location of the leak and the hearing status of the affected ear.If the leakage location was clear before surgery, direct repair was performed via mastoid path or middle cranial fossa path with or without mastoid abdominal fat packing.For patients with unclear leak, large lesion or intractable CEREBROspinal fluid leakage of temporal bone, subtotal petrosal resection and abdominal fat packing were performed.Subtotal temporal bone resection and abdominal fat packing were performed for patients with cochlear involvement. Results: In this study, cases of temporal bone CSF leakage including 13 cases of inner ear malformation; 5 cases secondary to head trauma or previous surgery,5 cases of idiopathic intracranial hypertension or meningocele, 2 cases of langerhans histiocytosis in the temporal bone and 2 cases of inner ear inflammation. High resolution CT （HRCT） of temporal bone showed bone defect of inner auditory canal with vestibular communication in 13 patients with inner ear malformation.The temporal bone HRCT of the remaining 14 patients showed bone defects in the middle cranial fossa or posterior cranial fossa, while MRI of the temporal bone showed meningeal continuity interruption with cerebrospinal fluid inflow into the temporal bone or meningoencephalocele in 12 patients. The 26 patients were followed up from 6 months to 6 years. 1 patient lost follow-up.Meningitis recurred in only 1 patient with inner ear malformation, and subtotal resection of rock bone plus abdominal fat packing was performed.Postoperative hearing was preserved or improved in 7 patients.None of the patients had serious complications, and only 1 patient developed HB Grade Ⅱ facial paralysis after vestibular obliteration, and the facial paralysis recovered within one week. Conclusion: Temporal bone cerebrospinal fluid leakage is relatively rare. Surgical intervention should be taken as early as possible when conservative treatment is failure. Preoperative HRCT and MRI examination are necessary for the localization of the leakage, and individualized surgical approaches can be adopted according to the location of the leakage and the features of the lesion.
