在临床上往往可以见到咽鼓管功能障碍的老年人,其中大部分为咽鼓管狭窄,也有部分咽鼓管异常开放的病人。作者以一年中主诉耳闷,自听过强被诊断为咽鼓管狭窄或异常开放的20岁以上的689名患者为对象,以咽鼓管鼓室气流动态图及外耳道声波图测定咽鼓管的功能,讨论随年龄增加咽鼓管功能的变化,并划分了狭窄型及开放型的年龄分布。还对从解剖材料中得到的74个咽鼓管,从肌肉、软骨、分泌腺、粘膜上皮及皮下结缔组织等讨论各年龄组咽鼓管的组织学改变。 689名患者中,狭窄症642人(占93%),异常开放症47人(占7%)。患者中60岁以上221人,其中狭窄症205人(占93%),开放症16人(占7%)。患狭窄症的642人中,老年占32%;
Clinically, the elderly can often see eustachian tube dysfunction, most of them are eustachian tube stenosis, there are some patients with abnormal eustachian tube open. The author complained of a year in the middle of obstruction, since the hearing was strongly diagnosed as eustachian tube stenosis or abnormal open 689 patients over the age of 20 as the object, the eustachian tube tympanum flow diagram and the auditory canal auditory canal Eustachian tube Function, to discuss changes in Eustachian tube function with age, and divided the narrow and open age distribution. 74 eustachian tubes obtained from anatomical materials were also used to discuss the histological changes of the eustachian tubes of various age groups from muscles, cartilage, glands, mucosal epithelium and subcutaneous connective tissue. Among 689 patients, stenosis was 642 (93%) and abnormal openness was 47 (7%). Of the patients, 221 were over the age of 60, of whom 205 were stenoses (93%) and 16 were open (7%). 642 people with stenosis, the elderly accounted for 32%;
