To Study The Role Of Concha Bullosa In The Aetiology Of Deviated Nasal Septum (DNS) And Sinusitis

AIMS AND OBJECTIVES : To study the role of concha bullosa in the devlopment of deviated nasal septum(DNS) and sinusitis. MATERIAL METHODS: 235 CT scans of paranasal sinuses done from March 2022 to November2022 were studied and evaluated for the presence of concha bullosa, DNS andsinusitis. RESULTS: Among 235 CT scans concha bullosa was found in 74(31.4%)patients.Among these patients, concha bullosa coexisting with DNS was found in56(75.7%) patients.Now, among these air column between concha bullosa and theseptum was found in 43 (76.7%) patients.Sinus disease was present in 48(64.8%)patients. CONCLUSION: Concha bullosa has a strong association with the existence ofconcomitant DNS.However, the presence of air column may exclude the role ofconcha bullosa in the aetiology of DNS. Presence of concha bullosa may predisposeto Sinusitis.
