Anatomical variants, clinical presentation and pathological findings in patients suffering from chronic rhinosinusitis underwent functional endoscopic sinus surgery

In this study, we investigated the different anatomical variations and clinical modes of presentation of chronic rhinosinusitis and their association with final histopathological diagnosis. This prospective randomization research was conducted on a total of 284 patients with chronic rhinosinusitis who underwent functional endoscopic sinus surgery from March, 2009 to September, 2012. The study population (284 patients) included 170 males (59.8%) and 114 females (40.1%), with a mean age of 29 years. The most frequent symptoms were nasal obstruction (24.3%); headache (21.9%), nasal congestion (18.5%) and post nasal discharge (16.6%). The nasal septums were significantly deviated in 207 (79.2%) subjects. Inferior turbinate hypertrophy was observed in 102 (35.9%) patients. Bulla ethmoidalis was reported in 32 (11.3%) participants. Uncinate bulla and concha bullosa were identified in 12 (4.2%), 12 (4.2%) patients, respectively. According to pathological report, majority of the patients (184 patients, 64.7%) had chronic inflammation in sinuses went after polyp in 46 patients (16.9%). Our study revealed anatomical variations were common in patients with chronic rhinosinusitis. Identification of different variations will guide the surgeons during functional endoscopic sinus surgery.   Key words: Chronic rhinosinusitis, functional endoscopic sinus surgery, anatomical variations.
