6岁以内小儿鼓室压与静态声顺值的特点

目的:探讨≤6岁小儿中耳鼓室压和静态声顺值与年龄的相关性。方法:将≤6岁小儿302例(567耳),依据不同的年龄段分为5组,分别检测其中耳鼓室压和静态声顺值,并统计其分布比例。结果:各组的鼓室压分布以+50～-50 daPa区间的比例最大。静态声顺值以3个月内的婴儿为最大(平均达到0.71 ml),3个月～3岁呈渐减趋势,3岁以后则逐渐增加,至6岁仅为1岁左右时的水平。结论:6岁以内小儿的鼓室压和静态声顺值与年龄因素有非常密切的关系,在临床工作中应考虑这一因素可能带来的影响。

Characteristics of tympanic cavity pressure and static compliance in 0～6 years old children

Objective:To explore the Characteristics of tympanic cavity pressure and static compliance in different years old children. Method: 302 cases (567 ears) were studied. All cases were divided into five groups according to their age. Their tympanic cavity pressure and static compliance were tested. Result: Most tympanic cavity pressure ranged from +50 to -50 dapa in all groups. The volume of static compliance in group one is the largest (0. 71 ml), and it changed with the age. It gradually decreased from 3 month to 3 years old but increased after three years old until 6 years old then returned to the level in 1 year old. Conclusion: The tympanic cavity pressure and static compliance are relevant to the age when children are small than 6 years. This characteristic must be considered on clinic diagnosis of middle ear disease and the evaluation of hearing.
