Abstract
A study of radiological findings in chronic rhinosinusitis in southern india
Highlights
Sinus infection lasting for months to years is called chronic sinusitis
The study included 54 patients diagnosed with chronic rhinosinusitis undergoing Functional Endoscopic Sinus Surgery (FESS) from November 2015 to February 2017, in whom we searched for salient features of chronic rhinosinusitis in Computed tomography and the anatomical variations in these patients
In our study we found anatomical variation in osteomeatal complex of 87% of patients with chronic rhinosinusitis, out of which 53.7% had two or more anatomical variations and the remaining 33.3% had single anatomical variation
Summary
Sinus infection lasting for months to years is called chronic sinusitis. Most important cause of chronic sinusitis is failure of acute infection to resolve. Acute infection destroys normal ciliated epithelium impairing drainage from the sinus. Pooling and stagnation of secretions in the sinus invites infection. Persistence of infection causes mucosal changes, such as loss of cilia, oedema and polyp formation, continuing the vicious cycle. Mixed aerobic and anaerobic organisms are often present. Clinical features are often vague and similar to those of acute sinusitis but of lesser severity. Purulent nasal discharge is the commonest complaint. Foul - smelling discharge suggests anaerobic infection. Local pain and headache are often not marked except in acute exacerbations. Some patients complain of nasal stuffiness and anosmia
