The Relationship Between Nasal Septal Deviation and Rhinosinusitis: A Systematic Review

Area of Science:

• Otolaryngology
• Medical Research Methodology

Background:

• Nasal septal deviation (NSD) and rhinosinusitis (RS) are prevalent conditions with overlapping symptoms, necessitating distinct treatment strategies.
• Understanding the relationship between NSD and RS is crucial for developing effective preventative management.

Purpose of the Study:

• To systematically review and analyze the existing literature on the association between nasal septal deviation and rhinosinusitis.

Main Methods:

• A systematic review adhering to PRISMA guidelines was conducted, searching Embase, MEDLINE, and Web of Science.
• Included studies focused on adult participants (≥18 years) and examined the association between NSD and RS based on prevalence, severity, and nasal septal angle (NSA).
• Risk of bias and overall study quality were assessed.

Main Results:

• Out of 34 studies, 40% of individual outcome measures indicated an association between NSD and RS.
• Studies assessing NSD prevalence showed a 41.2% association with RS, while 40% of studies on NSD severity found links to moderate/severe NSD.
• Only 35.3% of studies were assessed as low risk of bias, with fewer demonstrating an association.

Conclusions:

• The current evidence suggests an inconclusive relationship between nasal septal deviation and rhinosinusitis.
• Variability in definitions, diagnostic criteria, outcome measures, and insufficient bias control limit definitive conclusions.
• Standardized reporting guidelines are proposed to enhance consistency and enable more meaningful comparisons for future research and patient care.
