螺旋CT在儿童腺样体肥大中的应用价值

Application Value of Spiral CT in Children Adenoidal Hypertrophy

目的评价螺旋CT技术在儿童腺样体肥大中的临床应用价值。方法对疑诊为腺样体肥大的患儿进行X线平片和/(或)螺旋CT检查。选取57例经鼻咽镜和/(或)手术证实且两种资料齐全的腺样体肥大进行分析,对腺样体进行准确测量,测量腺样体的厚度及计算腺样体/鼻咽腔比值(A/N比值),并将两种资料结果进行对比。结果X线平片及CT显示所有病例腺样体均有增厚,两者对腺样体肥大的测量有显著差异(u1=2.76>2.58,P1<0.01;u2=3.25>2.58,P2<0.01),CT较X线平片更准确。同时,CT还显示了所合并的鼻窦炎27例,咽鼓管受压变窄13例,中耳乳突炎8例,鼻甲肥大15例,鼻息肉2例,腭扁桃体肥大4例;而X线平片均未显示上述合并症。结论螺旋CT技术,尤其是重建技术的应用对腺样体肥大及其合并症的显示均明显优于X线平片,可以为临床诊断及治疗提供准确的信息,是一种较理想的检查手段。

Objective To evaluate the for children adenoidal hypertrophy. Methods clinical application valuation of spiral CT techniques The patients maybe with adenoidal hypertrophy received X - ray and/or spiral CT scanning. In 57 patients with adenoidal hypertrophy proved by throat mirror tracer and/or surgery, and the two data is complete, choosing the spiral CT scanning images of 57 patients to evaluate. Accurately measuring the samples of adenoidal hypertrophy to obtain thickness of adenoid, calculating the ratio of adenoid/nasal pharynx （A/N ratio）, and comparing the results of two examining methods. Results X - ray and images of spiral CT both demonstrated that all samples of adenoid become thick, but the two results are statistical difference （ u1 = 2.76 〉 2.58, P , 〈 0. 01 ; u2 =3.25 〉2.58, P2 〈0. 01 ）. The result of spiral CT scanning is more accurate than X -ray. At the same time the images of spiral CT showed the following complication： 27 cases of nasosinusitis, 13 cases of stricture of eustachian tube, 8 cases of tuberculosis of middle ear and mastoid, 15 cases of turbi- nate hypertrophy, 2 cases of rhinopolyp, and 4 cases of hypertrophy of talatine tonsil, but the X - ray didn＇t show these complication. Conclusion The application of Spiral CT techniques, special reconstitution techniques, is better for diagnosis of adenoidal hypertrophy and its complications, can provide valuable information for clinical diagnosis and treatment, and is a more ideal examining method.
