Abstract
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.
摘要
对50例慢性鼻窦炎患者评估了低剂量CT的作用。CT很容易检测出疾病和相关的解剖变异，在78%的病例中观察到了这些情况。最常见的解剖变异是鼻中隔偏曲（38%），其他发现的变异包括泡状鼻甲（28%）和Helle细胞（28%）。最常见的疾病模式是36%的病例为窦口鼻道复合体模式。漏斗状模式见于23%的病例，蝶筛隐窝模式见于12%的病例，鼻窦息肉样模式见于16%的病例。低剂量CT是首选，因为它能给出与标准CT一样好的结果，即使必须反复使用，辐射危害的可能性也非常小。
