Background: Intrathecal fluorescein is commonly used to localize cerebrospinal fluid leaks. This technique is invasive and associated with several potential adverse effects. The purpose of this video presentation is to demonstrate an alternative technique, the intranasal use of dilute topical fluorescein, to localize a cerebrospinal fluid leak intraoperatively. Methods: A 45-year-old male with a history of benign intracranial hypertension and 2 months of right-sided rhinorrhea underwent surgical repair of a cerebrospinal fluid leak. Topical fluorescein was applied intraoperatively to localize the defect. Results: At 1- and 3-month follow-ups the patient was without cerebrospinal fluid rhinorrhea and the middle turbinate flap was intact. Conclusion: Topical application of dilute intranasal fluorescein is a feasible and efficient tool for localizing cerebrospinal fluid leaks.
