Demographic characteristics, CSF leak location, surgical procedure, etiology, smell test results were retrospectively reviewed. Results. A total of 27 patients were included. The mean age was 43.52 years. The etiology was spontaneous in 13 (48.1%) and traumatic in 14 (51.9%) patients. The skull base defect was at cribriform plate in 15 (55.6%) patients, frontal sinus posterior wall in 4 (14.8%), sphenoid sinus posterior wall in 4 (14.8%), around the anterior ethmoid artery in 2 (7.4%), ethmoid roof in 1 (3.7%), and sphenoid sinus posterolateral wall in 1 (3.7%) patient. After the comparison of preoperative and postoperative values in identification, discrimination and threshold categories, we detected a statistically difference only in threshold category (p=0.014). Conclusion. Our results demonstrated that endoscopic repair of CSF leak is safe in terms of olfactory functions.
