"Sealing the Gap" : CSF Leakage Demystified-A Comprehensive Analysis of our Experience in CSF Rhinorrhea Management

CSF (Cerebro Spinal Fluid) rhinorrhoea occurs when the fluid leaks from subarachnoid space into the nasal cavity. The study aims to find out the prevalence and demographic distribution of CSF leak and to describe the site of the CSF leak along with the management. We did a prospective study on 180 patients admitted with head injury in neurosurgery department, along with the patients who came to ENT department with unilateral nasal discharge during the time period from March 2017 to March 2021. A total of 36 cases of CSF leak were obtained during the time period. The etiology in 18 cases was head injury & the other 18 cases were either due to infectious or nontraumatic causes. In our study, 26(72.22%) patients were aged less than 50 years. Incidence was more among males compared to females. The most common etiology was head injury - 18(50%) patients followed by the spontaneous leak- 16 (44.44%) patients with the most common site as the cribriform plate. Endoscopic repair using a hadad flap was done in most of the patients. Trauma due to head injury is the most common etiology in CSF rhinorrhea with more number of patients aged less than 50 years. Most of the leaks can be repaired successfully with the use of endoscope with excellent illumination & localizing the exact site of the leak.
