咽鼓管咽口及其周围形态学改变与分泌性中耳炎的相关性研究

目的:研究咽鼓管咽口及其周围形态学改变与分泌性中耳炎(SOM)的相关性。方法:72例(144耳)正常人为对照组,89例(151耳)SOM患者为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组成人咽鼓管咽口形态中三角形及缝隙形的差异有统计学意义(均P<0.01);②对照组和SOM组儿童咽鼓管咽口形态差异无统计学意义;③成人SOM咽鼓管咽口周围形态改变与儿童不同。结论:①成人咽鼓管咽口形态改变在SOM的发生、发展中有着不可忽视的相关性,为探索成人SOM的治疗提供了一个新的思路。②在SOM组儿童中发现所有患儿咽鼓管咽口周围主要是鼻咽部炎症,次之是腺样体肥大和咽鼓管扁桃体肥大。③本研究采用纤维鼻咽镜直接观察咽鼓管咽口及鼻咽侧壁,对于明确SOM的病因和选择治疗方案具有重要意义。

Study of morphological alterations in pharyngeal ostium of Eustachian tube and its surrounding tissue and its association with SOM

Objective:To observe the morphological alterations in pharyngeal ostium of Eustachian tube and its surrounding tissues and its correlation with secretory otitis media.Method:72 volunteers(144 ears) as control group,89 patients(151 ears) as SOM group,all were observed for the shape of pharyngeal opening of auditory tube and the morphological changes of its surrounding structures.Result:Statistic difference was found between the shape of pharyngeal ostium of eustachian tube of adult patients with SOM and that of control group,but for children,there was no difference.It indicated that there was a difference between adult and children in morphological changes of pharyngeal ostium of eustachian tube when suffered from SOM.Conclusion:Morphological changes of pharyngeal ostium of eustachian tube play an important role in the genesis and development of adult SOM.The primary change in children patients is the inflammation of nasopharynx,then is the hypertrophy of adenoid and tubal tonsil.Nasopharyngo-fiberoscope is a very useful tool in the diagnosis and treatment of SOM.
