Study of various Anatomical and Pathological Parameters using Computed Tomography in Sino-Nasal Disease-a 1-year Hospital-based Observation Study

Computed Tomography (CT) is imperative in establishing a diagnosis in sino-nasal disease and in planning surgery. Various CT parameters like the infundibular, osteomeatal, sphenoethmoid and sino-nasal polyposis types were studied in a total of 30 patients i.e. 60 sides by using standard protocol. The study was done over a period of one year in a tertiary care hospital. The infundibular pattern was the commonest with a prevalence of 25%. Various authors in different regions of the world have studied similar patterns and it can be concluded that there is a wide inter and intra regional variation. This also helps us to understand that sino-nasal disease affliction is limited by race and region and hence, a clear cut pattern of prevalence of various parameters is not possible. Hence, this also stresses on the additional use of CT scan in assessing the pattern of pathology in order to achieve better disease clearance thus avoiding morbidity associated with recurrence.
