Endoscopic repair of spontaneous cerebro-spinal fluid rhinorrhoea: a report of 3 cases

Three cases of spontaneous Cerebrospinal Fluid (CSF) rhinorrhea were managed at the National University Hospital, Kuala Lumpur. Case 1 had bilateral leak secondary to empty sella syndrome and the rest two cases had unilateral leak. Four transnasal endoscopic approaches were performed on these three cases since March 1999. The role of intrathecal Sodium Fluorescein is highlighted in localising the CSF fistula. Case 3 required postoperative lumbar drain as an adjunct. No recurrent leak was noted on post operative follow up in Case 2 and 3 ranging from nine to thirty two months. A recurrent left leak at six months was noted in Case 1 which could likely be due to her sudden bout of cough attacks and patient refused further surgical intervention.
