Septal deviation is linked to a higher prevalence of rhinosinusitis, though its impact is modest. This anatomical variation is one of several potential factors contributing to rhinosinusitis development.
Area of Science:
- Otolaryngology
- Anatomy
- Epidemiology
Background:
- Rhinosinusitis presents with inflammation and impaired mucociliary clearance, potentially stemming from various etiologies.
- Anatomical factors, particularly septal deviation, have been investigated for their role in rhinosinusitis pathogenesis with conflicting results.
- The multifactorial nature of rhinosinusitis necessitates re-evaluation of potential anatomical contributors.
Purpose of the Study:
- To systematically analyze the association between septal deviation and rhinosinusitis.
- To define the relationship and explore possible etiologic mechanisms.
- To address limitations of previous studies by examining a larger combined sample.
Main Methods:
- Systematic analysis of previously published studies.
- Literature search to identify articles on septal deviation and rhinosinusitis.
- Quantitative and qualitative analysis of selected studies, using a 10-degree septal deviation angle (SDA) cutoff.
Main Results:
- 13 articles were included in the review, analyzing over 300 initially identified references.
- Increasing septal deviation angles correlated with higher rhinosinusitis prevalence.
- Combined analysis showed a significant association (P = .0004), with a modest odds ratio of 1.47. Inflammation was bilateral in all examined cases.
Conclusions:
- Septal deviation is associated with an increased prevalence of rhinosinusitis.
- The clinical impact of septal deviation as an isolated factor is limited.
- Septal deviation is considered one of multiple potential factors in rhinosinusitis development.
