Preoperative topical intranasal fluorescein in diagnosis of cerebrospinal fluid rhinorrhea

Cerebrospinal fluid rhinorrhea: diagnosis and management.

Advances in imaging and endoscopic techniques have improved the ability to diagnose, localize, and treat in a less morbid fashion CSF leaks of the anterior skull base. An appreciation for the mechanism of leak and of the relationship between CSF production and absorption must be kept in mind when individualizing a repair. Increased CSF pressure caused by overproduction or underabsorption may re...

Spontaneous cerebrospinal fluid rhinorrhea

INTRODUCTION Spontaneous cerebrospinal fluid leakage is usually caused by developmental abnormalities and is rare, accounting for approximately 5% of the cases of cerebrospinal fluid (CSF) leakage. To the best of our knowledge, clival dysplasia-caused CSF rhinorrhea has never been reported in the neurosurgical field. CONCLUSION Spontaneous cerebrospinal fluid rhinorrhea is often treated by su...

The use of low- dose intrathecal fluorescein in endoscopic repair of cerebrospinal fluid rhinorrhea.

BACKGROUND Intrathecal injection of fluorescein is a useful adjuvant method for localization of fistulas in endoscopic endonasal repair of cerebrospinal fluid (CSF) leakage. Although being neurotoxic in commercial doses, a low dose of diluted fluorescein seems to be safe on the basis the existing data in the literature. OBJECTIVES The purpose of this study was to investigate the role of a low...

An inexpensive blue filter for fluorescein-assisted repair of cerebrospinal fluid rhinorrhea.

INTRODUCTION The endoscopic approach to the repair of cerebrospinal fluid (CSF) rhinorrhea represents a considerable advance over open approaches. Advantages of the endoscopic approach include a high success rate, rapid recovery and discharge, preservation of olfaction, avoidance of frontal lobe retraction, and avoidance of a craniotomy scar. Intraoperatively, repair cannot be attempted until t...
