A study on role of anatomical obstruction in pathogenesis of chronic sinusitis.

This is a study about the role of obstructive anatomic variations in the osteomeatal complex of the nasal cavity leading to the development of chronic sinusitis, conducted in a tertiary care centre between July2011 to November2013. About 50 patients were studied for the frequency of occurrence of main anatomical variants like nasal septum deviation, pneumatised middle turbinate, paradoxically curved middle turbinate and infraorbital ethmoid air cell(haller cell), which was compared with a control group of 50 patients on the basis of nasal symptoms of sinusitis and radiological imaging by CT scan of the paranasal sinuses. All the patients were evaluated for the effectiveness of endoscopic sinus surgery by evaluating for the improvement of symptoms and patency of the sinus drainage. Nasal septum deviation followed by pneumatised middle turbinate and paradoxical middle turbinate was the commonly observed anatomical variation at the osteomeatal complex and there was significantly good improvement of the disease symptoms and quality of life following endoscopic sinus surgery.
