Abstract

Introduction: Nasal septal deviation is a common anatomical abnormality associated with rhinosinusitis due to osteomeatal complex narrowing and mucociliary dysfunction. However, studies exploring this specific relationship remain limited and yield variable results. This study aimed to analyze the relationship between the type and degree of nasal septal deviation and the incidence of rhinosinusitis based on computed tomography (CT) imaging evaluation.

Methods: This observational analytical study used a cross-sectional approach at Sebelas Maret University Hospital from September to December 2025. 28 patients were recruited using a total sampling technique. Key variables evaluated through CT scans included the type of septal deviation (Mladina classification), the degree of deviation, and rhinosinusitis incidence. Data were analyzed using the non-parametric Spearman Rank correlation test.

Results: The sample was dominated by adult (82.1%) and female patients (82.1%). Based on the Mladina classification, type 2 septal deviation was the most prevalent (46.4%). The majority of patients (67.9%) had a mild degree of deviation (angles 0°–9°). Clinically, 46.4% of patients were diagnosed with rhinosinusitis. Statistical tests showed no significant relationship between the type of septal deviation and rhinosinusitis incidence (p=0.313; r=0.198). Similarly, no significant association was found between the degree of septal deviation and rhinosinusitis incidence (p=0.703; r=0.075).

Conclusion: There is no significant relationship between the type or severity of septal deviation and rhinosinusitis incidence. Structural anomalies in the nasal septum are not absolute predictors of paranasal sinus inflammation. The multifactorial nature of rhinosinusitis, osteomeatal drainage patency, and aerodynamic adaptation mechanisms play a more crucial clinical role.
