Multiple Port Frontal Sinusotomy - its Role in CSF Rhinorrhoea

Abstract

Abstract Surgical management of CSF rhinorrhoea usually includes neurosurgical craniotomies or endonasal endoscopic procedures. Choice of surgical venture depends on the site of defect or expertise of available surgical skill. This study attempts to highlight the use of nasal endoscopes by multiple port frontal sinusotomies in select situations. Eight patients with spontaneous CSF rhinorrhoea underwent surgical management using nasal endoscopes between Mar 2011 to Mar 2012 in Dept ofENTand Head&Neck surgery,CommandHospital, Kolkata. Identification of site of defect was done with MRI or CT scans. Six cases of defects in ethmoidal roof and skull base were approached endonasaly. In two cases where defect lied in the posterior table of frontal bone, endoscopes were used through multiple frontal sinusotomies. Monthly postoperative reviews were done for six months. The repairs were successful in all cases irrespective of the approach used. In select situations, major neurosurgical operations can be avoided and frontal bone defect can be successfully repaired using minimally invasive endoscopic repair through multiple frontal sinusotomies.
