Low-dose intrathecal fluorescein and etiology-based graft choice in endoscopic endonasal closure of CSF leaks

Low-dose ITF is a safe and useful adjunct to endoscopic endonasal repair of CSF leaks with minimal complications and successful localization of the leak in approximately 80%. An etiology-based approach to graft choice and duration of lumbar drain placement in CSF leak repair may optimize closure rates.
