低剂量64排螺旋CT对维吾尔族、汉族儿童腺样体肥大的诊断与临床对比分析

目的:探讨南疆地区维吾尔族、汉族儿童腺样体肥大的低剂量64排螺旋CT征象与临床发生率差异。方法:总结我院140例维吾尔族、汉族儿童腺样体肥大的CT征象及临床表现,测量鼻咽腔大小及后壁软组织厚度,计算腺样体指数;计算并分析南疆地区维吾尔族、汉族儿童各型腺样体肥大的发生率。结果:南疆地区汉族儿童Ⅰ型腺样体肥大的发生率明显高于维吾尔族(P<0.05)。Ⅱ、Ⅲ型腺样体肥大的发生率汉族、维吾尔族儿童无明显差异(P>0.05)。结论:1.两个民族的儿童Ⅰ型腺样体肥大的发生率有明显差异,汉族儿童发生率明显高于维吾尔族,可能与两个民族的鼻腔结构存在差异有关。2.低剂量64层螺旋CT是诊断儿童腺样体肥大的重要手段,在临床应用上有重要价值。

Diagnosis and Clinical Comparative Analysis on Adenoidal Hypertrophy among Uyghur and Han Children by Low-Dose 64-Slice Spiral CT

Objective：To study clinical incidence of adenoidal hypertrophy uighur and han children in south region by low-dose 64-slice spiral CT analysis. Methods CT of adenoidal hypertrophy and clinic symptom of 140 eases were summarized, which were all from uighur and han, the size of the nasopharynx,along with the thickness of the posterior wall of soft tissue were measured, as well As the adenoid index was estimated, moreover, the clinical incidence of adenoidal hypertrophy uighur and han children in south region were calculated and analyzed. Results incidence of type Ⅰ adenoidal hypertrophy in han children in south region is higher than that of the uighur children （p〈0.05）, and there is no significant difference between han and uighur children in type Ⅱ, Ⅲ （p〉0.05）. Conclusion 1.no obviously difference were found between type Ⅱ, Ⅲ adenoidal hypertrophy,the incidence of han children is higher than that of uighur children in type Ⅰ, and it could be associated with the structure differences of nasal structure between two nationalities. 2. It could be an important methods to diagnosis the children adenoidal hypertrophy by low-dose 64-slice spiral ct, and it play important value in clinical applications.
