摘要
目的采用CT容积扫描及三维重建等技术建立上气道模型,探讨儿童腺样体大小与鼻咽腔容积关系,分析阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的影响。方法采集109例儿童鼻咽部CT图像后进行重建,测量并计算腺样体大小(A/N值)及鼻咽腔容积等参数。根据A/N值将所有儿童分为正常组和肥大组,根据是否患有OSAHS分为OSAHS组和非OSAHS组。比较正常组和肥大组间各参数差异,分析不同性别及不同年龄A/N值与鼻咽腔容积的关系,以及OSAHS对A/N值与鼻咽腔容积关系的影响。结果肥大组鼻咽腔容积[(3111.67±1304.73)mm^3]小于正常组[(4960.55±2036.14)mm 3,P<0.01],A/N值(0.69±0.11)大于正常组(0.45±0.97,P<0.01)。男性及女性儿童鼻咽腔容积与A/N值均呈负相关(r男=-0.43,r女=-0.42,P均<0.01)。5岁以下儿童A/N值与鼻咽腔容积的相关性(r=-0.43)小于6~10岁儿童(r=-0.49),OSAHS组A/N值与鼻咽腔容积相关性(r=-0.60)高于非OSAHS组(r=-0.33)。结论腺样体大小与鼻咽腔容积呈负相关且存在年龄差异。OSAHS患儿腺样体大小与鼻咽腔容积的相关性更高。
Objective To explore the relationship of children adenoid and nasopharyngeal volume using upper airway model established with CT volume scanning and three-dimensional reconstruction technology,and to analyze the impact of obstructive sleep apnea hypopnea syndrome(OSAHS).Methods Nasopharyngeal CT images of 109 children were collected.After reconstruction of all images,the size of adenoid(A/N value)and nasopharyngeal cavity volume were measured and calculated.The children were divided into normal group and hypertrophic group according to A/N value,also OSAHS group and non-OSAHS group according to whether had OSAHS or not.The indexes were compared between normal group and hypertrophic group.The correlation of A/N value and nasopharyngeal cavity volume in different genders and ages were analyzed,and the impact of OSAHS on the relationship of A/N value and nasopharyngeal cavity volume was observed.Results Nasopharyngeal volume of hypertrophic group([3111.67±1304.73]mm^3)was smaller than that of normal group([4960.55±2036.14]mm 3,P<0.01).A/N value of hypertrophic group(0.69±0.11)was greater than that of normal group(0.45±0.97,P<0.01).The nasopharyngeal volume was negatively correlated with A/N value in both genders(r male=-0.43,r female=-0.42,both P<0.01).The correlation coefficient of A/N value and nasopharyngeal volume in children<5 years old(r=-0.43)was less than that in children aged 6-10 years old(r=-0.49),and of OSAHS group(r=-0.60)was higher than of non-OSAHS group(r=-0.33).Conclusion Negative correlation of adenoid size and nasopharyngeal cavity volume exists,which is of age difference.Compared with non-OSAHS children,adenoid size is obviously correlated with nasopharyngeal cavity volume in children with OSAHS.
