Aim: To evaluate the nasal septal deviation by measuring the angle of deviation and study its relation with sinus diseases and lateral nasal wall anomalies, by diagnostic endoscopy (DNE) and computed tomography (CT), in patients with chronic rhinosinusitis (CRS).
Materials and methods: A prospective study was carried out on 90 patients with nasal complaints and deviated septum, attending the Department of Otorhinolaryngology, from January 2015 to August 2016. Patients diagnosed to have CRS clinically were subjected to DNE and CT scans. The maximum angle of septal deviation was calculated in coronal cuts. The side and sites of rhinosinusitis and lateral wall anatomical variants were identified.
Results: The prevalence of CRS was 73%, with males more affected than females (1.8:1). Left-sided and C-shaped deviated nasal septum (DNS) was most common. About 52% patients suffering from CRS had septal angle of deviation between 7° and 12°, 46% had more than 12°. Maxillary sinus was the most commonly involved sinus. Concha bullosa (32%) was the most common variant noted. Occurrence of medialized uncinate process was found to be increasing on the ipsilateral side of deviated septum with increasing angle of deviation.
Conclusion: In patients with chronic sinusitis, most of the angles were deviated between 7° and 12°. The mean deviation was 12.92°. Majority of patients with chronic rhinosinusitis had a concurrent variation along with DNS. No correlation was found between the side of DNS and side of maxillary sinusitis. No corelation was noted between the anatomical variants of lateral nasal wall with increasing angle of deviation.
Clinical significance: Our study emphasizes the multifactorial etiology behind CRS with plausible role of genetic factors, environmental influence, allergic factors, hormonal influence, etc., in its causation.
