A Case of Transnasal Endoscopic Repair of Iatrogenic Bilateral Cerebrospinal Fluid (CSF) Rhinorrhea

Cerebrospinal fluid (CSF) rhinorrhea results from a breakdown of dura that is supported structures of the skull base. CSF rhinorrhea usually occurs after head trauma or follows surgery for various inflammatory or tumorous disease at the anterior cranial base. Surgical repair is recommended for patents with CSF leaks that do not respond to conservative management. It was managed previously through the intracranial approach. However, it has been reported high morbidity and mortality. The nasal endoscope can be used to improve visualization of the leakage site and to facilitate free graft of flap placement. This method ensures a high rate of dural defect healing with minimal morbidity. The authors have experienced a case of iatrogenic bilateral CSF rhinorrhea from ethmoidal roof area, in which repaired successfully with muscle fascia, fibrin glue under nasal endoscopy. Therefore, we present this case with review of the literatures. (J Clinical Otolaryngol 2001;12:110-113)
