Endoscopic and Computed Tomographic Evaluation of Influence of Nasal Septal Deviation on Lateral Wall of Nose and Its Relation to Sinus Diseases

Original Article

Abstract

To correlate symptoms of deviated nasal septum (DNS) and chronic rhinosinusitis with the findings of nasal endoscopy and computed tomographic (CT) imaging. To evaluate the influence of degree of septal angle deviation on the severity of lateral nasal wall abnormalities. A prospective study was conducted on 67 patients with clinical evidence of DNS and chronic sinusitis attending ENT OPD between January 2012 and September 2013. All these patients underwent nasal endoscopy and CT scan PNS coronal sections. Direction and degree of DNS was recorded. Range of sinus mucosal thickening on CT scan films was also recorded. Chronic sinusitis is common in the age group between 21 and 40 years (50.74 %) with male preponderance (55.22 %), chief symptoms being nasal obstruction (86.56 %), headache (73.13 %) and nasal discharge (52.23 %). Left sided DNS is more common (64.17 %). Most of the patients have moderate DNS, i.e. 6°–10° (56.7 %), followed by severe (22.4 %) and then mild (20.9 %). DNS results in compensatory structural changes in the turbinates and/or lateral nasal wall which causes ostiomeatal complex (OMC) obstruction resulting in sinusitis. Contralateral concha bullosa and ethmoid bulla prominence was noted. Maxillary sinus is most commonly affected sinus (73.13 %). Patients with increasing septal angles were associated with a higher incidence of maxillary sinus mucosal changes (p < 0.05). Present study reemphasized the concept that septal deviation causes obstruction at OMC which results in an increased incidence and severity of bilateral chronic sinus disease.
