Background:
Management strategies employed for cases of cerebrospinal fluid (CSF) rhinorrhea vary widely because of limited evidence-based guidance.
Methods:
A systematic review of the literature was performed using PubMed, EMBASE, and Cochrane databases from January 1990 through September 2014 to examine 5 endoscopic repair techniques and 8 perioperative management strategies for CSF rhinorrhea. Benefit-harm assessments, value judgments, and recommendations were made based on the available evidence. Study exclusion criteria were language other than English, pre-1990 studies, case reports, and nonrhinologic leak. All authors agreed on recommendations through an iterative process.
Results:
We reviewed 67 studies examining 13 practices pertinent to the management of CSF rhinorrhea, reaching a highest aggregate grade of evidence of B. The literature does not support the routine use of prophylactic antibiotics or lumbar drainage. Various endoscopic repair materials show similar success rates; however, larger defects may benefit from vascularized grafts. There were no relevant studies to address postoperative activity restrictions.
Conclusion:
Despite relatively low levels of evidence, recommendations for the management of CSF rhinorrhea can be made based on the current literature. Higher-level studies are needed to better determine optimal clinical management approaches.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
