作者们对在523名三岁儿童的普查中示有鼓室功能曲线(tympanogram)异常的372耳,进行为时半年的追踪观察,发现半年后40名儿童74耳的鼓室功能曲线仍为B型和/或鼓室负压≤-200mmH_2O。本文就这些患耳鼓室穿刺抽液的情况,结合随访中的鼓室压力、静态声顺值、绝对梯度和相对梯度等参数进行了分析探讨。所得结论是:(1)鼓室压力和积液的量之间并无规律性关系。这可能和本组病例的穿刺和鼓室功能检查之间的间隔期较长有关。(2)绝对声顺值≤1.5 Madsen单位者有27耳,其中26耳有大量或中量的积液。超过1.5则声顺值和积液量成反比。(3)
The authors observed 372 ears with tympanogram abnormalities during a census of 523 three-year-old children for a period of six months and found that the tympanic function curves of 74 ears of 40 children remained type B after six months / Or tympanic negative pressure ≤ -200mmH_2O. In this paper, the ear pumping of ear drum puncture case, combined with the follow-up tympanic pressure, static acoustic compliance, absolute gradient and relative gradient parameters were discussed. The conclusions obtained are: (1) There is no regular relationship between tympanic pressure and fluid volume. This may be puncture and tympanic function tests in this group of patients between the longer interval. (2) absolute acoustic compliance ≤ 1.5 Madsen units have 27 ears, of which 26 ears have a large amount or volume of effusion. More than 1.5 acoustic compliance and fluid volume is inversely proportional. (3)
