Endonasal endoscopic repair of ethmoid roof cerebrospinal fluid fistula by suturing the dura

摘要

Introduction Over the past 20years, improvement in surgical techniques as well advances in surgical instruments for sinus surgery has led to surgical closure of cerebrospinal fluid (CSF) leak using endoscopic approach. Minimally invasive and having lower post op morbidity, compared to traditional intracranial techniques, repairing CSF leak endoscopically has evolved to become the standard practice for management of CSF leak.
