慢性中耳炎时,影响鼓室成形术效果的主要原因,还是咽鼓管的功能。为研究咽鼓管功能,作者们应用EMT-32 C空气压力计与瑞士产Elema商标的Mingograph-81多导心动描记图联接,通过数种咽鼓管功能试验,测定外耳道压力改变,记录于记录纸带和示波器的屏幕上,单位以mmH_2O计算。共检查70例15～65岁的慢性中鼓室炎的病人和17名正常人。分析病人治疗过程中的资料,可分4组:第1组17例,压力波动在0.07±0.03、0.06±0.02、0.34±0.19 mmH_2O,评定为咽鼓管通过度不良。第2组29人,咽水试验压力0.67±0.08mmH_2O,Toynbee试验4.35±
Chronic otitis media, tympanoplasty affect the main reason, or eustachian tube function. To study Eustachian tube function, the authors used the EMT-32 C air pressure gauge to interface with the Mingograph-81 multi-guided multicentric electrocardiogram of the Swiss-made Elema brand. Several Eustachian tube functional tests were performed to determine changes in the pressure in the external auditory meatus and recording was recorded Tape and oscilloscope screen, the unit is calculated as mmH_2O. A total of 70 patients with chronic tympanitis aged 15-65 years and 17 normal subjects were examined. Analysis of the data during the treatment of patients can be divided into 4 groups: 17 cases in group 1, the pressure fluctuations in the 0.07 ± 0.03,0.06 ± 0.02,0.34 ± 0.19 mmH_2O, assessed as eustachian tube pass poor. 29 patients in group 2, 0.67 ± 0.08 mmH_2O in test of pharynx water, 4.35 ± in Toynbee test
