儿童腺样体肥大与中耳咽鼓管功能相关性分析

目的:探讨腺样体大小与中耳功能和咽鼓管功能的相关性。方法:回顾性分析2004年2月~2004年10月因腺样体肥大收入院手术患儿的中耳功能,并比较腺样体肥大患儿和正常同龄儿童的咽鼓管功能的差异。结果:①腺样体大小与中耳压力有明显的负相关性(r=-0.41,P<0.05);②腺样体肥大患儿咽鼓管功能(13.9±13.2)daPa,与正常儿童咽鼓管功能(22.5±10.4)daPa比较,差异有统计学意义(t=-3.1,P<0.01);③患儿腺样体的大小程度与咽鼓管功能无明显相关性(r=-0.19,P>0.05)。结论:腺样体病理性肥大可引起咽鼓管功能障碍,是分泌性中耳炎(SOM)的发病基础。

Relationship between adenoids hypertrophy and tympanogram/eustachian tube function in children

OBJECTIVE: To evaluate the correlation between adenoidal-nasopharyngeal ratio (AN ratio) and tympanogram/eustachian tube function in children. METHOD: A prospective clinical study from February 2004 to October 2004 was carried out. A total of 120 children with adenoids hypertrophy and 20 normal children were examined. The relationship between AN ratio and middle-ear pressure was evaluated, the eustachian tube function was campared between the children with adenoids hypertrophy and the normal. RESULT: (1) Middle ear pressures were negative related to the AN ratio (r = -0.41, P < 0.05); (2) the eustachian tube function of the children with adenoids hypertrophy was worse than the normal; (3) the relation between the eustachian tube function and the AN ratio was not statistical difference. CONCLUSION: Eustachian tube dysfunction caused by adenoids hypertrophy is the etiologic factor of secretory otitis media.
