Delayed Cerebrospinal Fluid Rhinorrhea Twenty Years After Septoplasty

A 56-year-old man underwent a septoplasty 20 years ago; however, one month prior to hospitalization he got a bad cold and cough, followed by a watery rhinorrhea. Computed tomography (CT) scan showed a defect in the right planum sphenoidale. After admission, with the typical clinic symptoms, the history of septoplasty and imageology evidence, the patient was diagnosed as delayed CSF rhinorrhea, and accepted a CSF rhinorrhea neoplasty with neuronavigation assistance under general anesthesia using an endoscopic approach. Intraperatively, we found an old bony defect 3×8mm in size at the planum sphenoidale. After 9 months of follow-up, there was no evidence of rhinorrhea.
