[Nasal irrigation: opportunities and disadvantages]

Area of Science:

• Otolaryngology
• Respiratory Medicine
• Mucosal Immunology

Background:

• Nasal irrigation is a widely adopted medical practice for upper respiratory conditions.
• The precise mechanisms of saline solutions acting on nasal mucosa are not fully elucidated.
• Understanding nasal mucus homeostasis is crucial for respiratory tract health.

Purpose of the Study:

• To analyze current data on the frequency, methods, and efficiency of systematic nasal irrigation.
• To investigate the specific effects of salt solutions on the nasal mucous membrane.
• To review the role of nasal irrigation in managing upper respiratory tract diseases.

Main Methods:

• Systematic review and analysis of recent scientific literature.
• Generalization of information on nasal irrigation's impact on the upper respiratory tract.
• Examination of data concerning the effect of nasal irrigation on mucosal defense mechanisms.

Main Results:

• Nasal irrigation plays a significant role in managing upper respiratory tract diseases.
• Nasal mucus is vital for maintaining homeostasis within the nasal cavity and respiratory tract.
• Nasal irrigation demonstrates a positive effect on the anti-infectious protection of the nasal mucous membrane.

Conclusions:

• Contradictions persist regarding the exact physiological effects of salt solutions on nasal mucosa during irrigation.
• Despite widespread use, a comprehensive understanding of nasal irrigation's effectiveness and mechanisms is still evolving.
• Further research is warranted to resolve existing discrepancies and optimize nasal irrigation protocols.
