Abstract

Cerebrospinal fluid (CSF) leak is one of the most common postoperative complications following endonasal surgery. The rate varies with defect location, tumor type, reconstruction technique, surgeon experience, and patient factors. CSF leak rates range from 1.5 to 5% for pituitary adenomas to 10 to 16% for craniopharyngiomas and meningiomas. The severity of intraoperative CSF leak also correlates with the risk of postoperative leak. While this relationship is intuitive, classifying the severity can be challenging.
