Rhinoscopic Clinic

Minimally invasive endoscopic closure is considered the treatment of choice for most CSF leaks. It is associated with a high success rate and low morbidity rate.

A 35-year-old woman presented to our ENT clinic with a 1-month history of a clear, watery, left nasal discharge on bending forward (figure 1) and an associated intermittent headache. She had no recent history of head trauma or skull base surgery. Other than the rhinorrhea, findings on physical examination were unremarkable. Flexible endoscopy revealed drainage of the clear fluid from the orifice of the left sphenoid sinus, even without the Valsalva maneuver (figure 2).
