儿童分泌性中耳炎咽鼓管咽口及其周围形态学观察

Observation on morphological alteration in pharyngeal orifice of Eustachian tube and its surrounding tissue in children with secretary otitis media

目的探讨咽鼓管咽口及其周围形态学改变与儿童分泌性中耳炎(SOM)的相关性。方法 75例(150耳)正常儿童为对照组,92例(152耳)SOM患儿为SOM组。用纤维鼻咽镜观察对照组和SOM组咽鼓管咽口的形态及SOM组咽鼓管咽口周围形态改变。结果 1、对照组和SOM组咽鼓管咽口形态的差异无统计学意义(均P>0.05);2、SOM组儿童发现所有患儿咽鼓管咽口周围主要是鼻咽部炎症(49%),次之是腺样体肥大(35%)和咽鼓管扁桃体肥大及咽口水肿(各占8%)。结论本研究采用纤维鼻咽镜直接观察咽鼓管咽口及鼻咽部组织形态,对于明确儿童SOM的病因和选择治疗方案具有重要意义。

Objective To investigate the correlation between morphological alteration in pharyngeal orifice of Eustachian tube and secretary otitis media（SOM）in children.Methods 75 healthy children（150ears）were in the control group,92 children（184ears） with SOM were in the experimental group.Through nasopharyngeal fiber microscope,we observed the shape in pharyngeal orifice of Eustachian tube and the morphological alterations around it in both groups.Results 1.The shape of pharyngeal orifice of Eustachian tube between control and experimental groups had no significant difference（P0.05）.2.In the experimental group,the morphological alterations around pharyngeal orifice of Eustachian tube mainly included： inflammation of nasopharynx（49%）,adenoidal hypertrophy（35%）,Eustachian tonsil（8%） and pharyngeal orifice edema（8%）.Conclusion Observing the morphological alterations in pharyngeal orifice of Eustachian tube and around it has directly significant effect on diagnosis and treatment.
