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。
OBJECTIVE: To investigate the relationship between tympanic pressure and static compliance and age in children under 6 years old. Methods: 302 cases (567 ears) of children ≤6 years old were divided into five groups according to different age groups. The middle ear tympanic pressure and the static acoustic compliance were measured, and the distribution ratio was calculated. Results: The tympanic pressure distribution in each group was the largest in the range of + 50 ~ -50 daPa. The static compliance value was the highest in infants within 3 months (averaging 0.71 ml), with a decreasing trend from 3 months to 3 years of age and gradually increasing after 3 years of age to 6 years of age only at the age of 1 year. Conclusions: The tympanic pressure and the static acoustic compliance of children under 6 years old are closely related to the age factors. The possible impact of this factor should be considered in the clinical work.
