Neuroendoscopic Transnasal Repair of Cerebrospinal Fluid Rhinorrhea.

Cerebrospinal fluid (CSF) rhinorrhea is a common condition managed by most otolaryngologists with the help of nasal endoscopy (sinoscopy). In the last 2 years, we have used a neuroendoscope with a working sheath to treat nine patients with CSF rhinorrhea. One patient developed a recurrence 1 month after treatment but then responded to conservative treatment. We conclude that the treatment of CSF rhinorrhea by a neuroendoscope with a working sheath is safe, effective, and easy and obviates the need for a separate sinoscope.
