Endoscopic management of cerebrospinal fluid rhinorrhea from anterior skull base defects
Authors
Abstract:
Abstract Background: Over the past 20 years, the minimally invasive endoscopic approach has gained widespread acceptance. The study was performed to evaluate the diagnostic method and the success rate of endoscopically diagnosed and treated CSF rhinorrhea, and also investigations such as leakage site and etiologic factor. Methods: This retrospective CSF leakage management review of patients experiencing CSF rhinorrhea made from 1999-2006 included data regarding leakage etiology, preoperative assessment, intraoperative techniques and postoperative followup. Result: Sixty-five patients were managed endoscopically. CSF rhinorrhea etiology was traumatic in 30 cases, iatrogenic in 23 and spontaneous in 12. We used nasal endoscopy and high resolution computed tomography (HRCT) in all 65 cases while CT metrizamide cisternography was used in 5 specifically and magnetic resonance imaging for 5 others. Intrathecal fluorescein was used for intraoperative assessment without complications, and only one case of meningismus was noted. Conclusion: Several imaging methods were effective in diagnosing CSF leakage sites. Endoscopic management and autografts were successful in repairing anterior skull defects in 90.76% of the cases.

The surgical management of cerebrospinal fluid (CSF) rhinorrhea has changed after the introduction of functional endoscopic sinus surgery.The following three cases illustrate the repair of CSF leaks with the use of rigid endoscope. Two patients had the diagnosis and the site confirmed after intrathecal fluoresceine saline injection. The obliteration of the CSF was achieved with fat free, mucope...

Objectives: Sinonasal schwannomas account for less than 4% of head and neck schwannomas, with the primary treatment modality being surgical excision via external approaches. The aim of this report is to present a rare case of recurrent schwannoma of the ethmoid cavity involving the anterior skull base which was successfully managed with endoscopic resection. Study Design: Case report and review...

Resection of the anterior clinoid process results in the creation of the clinoid space, an important surgical step in the exposure and clipping of clinoidal and supraclinoidal internal carotid artery aneurysms. Cerebrospinal fluid rhinorrhea is an undesired and potentially serious complication. Conservative measures may be unsuccesful, and there is no consensus on the most appropriate surgical ...
