Nasal saline irrigation: a clinical update.

Area of Science:

• Otolaryngology
• Rhinology
• Medical Devices

Background:

• Nasal saline irrigation (NSI) is a widely used, low-risk adjunctive treatment for chronic rhinosinusitis (CRS).
• NSI is believed to improve CRS by thinning mucus, enhancing mucociliary clearance, reducing edema, and decreasing nasal antigen load.
• Despite universal use, significant variability exists in NSI delivery methods, composition, and hygiene, with limited evidence on optimal practices and emerging safety concerns regarding primary amebic meningoencephalitis.

Purpose of the Study:

• To provide a clinical update on the use of NSI for CRS treatment.
• To summarize current recommendations, efficacy data, delivery devices, solution composition, and hygiene practices for NSI.

Main Methods:

• Review of current evidence and consensus statements regarding NSI for CRS.
• Analysis of data on NSI efficacy, delivery devices, solution composition, and hygiene protocols.

Main Results:

• Current evidence and recommendations for NSI delivery methods, composition, and hygiene are presented.
• Consensus statements and Cochrane Reviews support NSI for CRS, primarily based on lower-level evidence.

Conclusions:

• NSI is recommended for chronic rhinosinusitis (CRS) based on existing evidence.
• Optimal methods for NSI delivery and solution composition cannot be definitively determined from current literature.
• Further research is needed to establish best practices and address safety concerns associated with NSI.
