Tympanograms were obtained from normal preschool and adult subjects with a prototype hand-held tympanometer to obtain normative values for four tympanometric variables: static admittance, equivalent ear canal volume, tympanometric peak pressure, and gradient. Effects of age group, sex, and pump speed (200 or 400 daPa/s) were determined. The results were incorporated into a four-part screening protocol (history, visual inspection, audiometry, and tympanometry) designed to reduce the excessive error rates associated with screening strategies that rely exclusively on tympanometry.
使用一台手持式中耳分析仪原型,从正常学龄前儿童和成人受试者身上获取鼓室图,以获得四个鼓室测量变量的标准值:静态导纳、等效耳道容积、鼓室图峰值压力和梯度。确定了年龄组、性别和泵速(200或400 daPa/s)的影响。结果被纳入一个四部分的筛查方案(病史、视觉检查、听力测定和鼓室测量),该方案旨在降低与仅依赖鼓室测量的筛查策略相关的过高错误率。
