Cerebrospinal fluid leakage after turbinate submucosal diathermy: an unusual complication.

Submucosal diathermy of the inferior turbinate (SMDIT) is a generally safe procedure to control inferior turbinate hypertrophy. We present a case of a cerebrospinal fluid (CSF) leak at the craniocervical junction after SMDIT done in another institution. A 27-year-old man presented 3 weeks after undergoing SMDIT with signs and symptoms of meningitis and postnasal rhinorrhea. Nasal endoscopy and imaging revealed a nasopharyngeal CSF fistula at the craniocervical junction. Transnasal endoscopic repair and reconstruction was performed with no recurrence on repeat imaging and clinical follow up. We describe the first reported case in the literature of an iatrogenic CSF fistula caused by SMDIT, an unusual and potentially fatal complication, and its surgical management.
