Low dose ct in chronic sinusitis.

Role of low dose CT was assessed in 50 patients of chronic sinusitis. CT easily picks up the disease and predisposing anatomic variants, which were observed, in 78% of cases. The commonest anatomical variants was deviated nasal septum (38%),other variants found were concha bullosa in (28%) and Helle cell in 28% cases. The commonest disease pattern was osteomeatal unit pattern in 36% case. Infundibular pattern was seen in 23%, sphenoethmoidal recess pattern in 12% and sino-nasal polypopsis pattern was present in 16% of the cases. Low dose CT is preferred as it gives as good results as standard CT There is very little chances of irradiation hazard even when it has to be employed repeatedly.
