How we do it: endoscopic trans-nasal repair of CSF rhinorrhoea

Endoscopic repair of CSF rhinorrhoea was first described in the early 1980s. Since then the endoscopic approach has overtaken the intracranial route as the procedure of choice due to superior visualisation of the operative field, reduced operating time & lower complication rates. Various autogenous, allogenic and synthetic patching materials have been used to augment repair. We describe a step wise technique of patching the skull base defect using a combination of septal mucoperichondrial flap and tensor fascia lata graft.
