To determine the reliability, validity, and feasibility of a new hand held microtympanometer.
Comparison of microtympanometry by two independent observations of a general practitioner and a nurse, and against a validated reference instrument.
Primary care health centre of a school for the deaf in the United States.
111 schoolchildren receiving a regular check up.
Tympanometry with the Grason Stadler 28, classified with a slightly modified Jerger's classification.
Interobserver reliability was 0.95 (Cohen's kappa). Results of microtympanometry were highly comparable with results of the reference instrument (likelihood ratio of positive results, 161.2).
The microtympanometer could be used in general practice: it is hand held, child friendly, easy to handle, and accurate.
确定一种新型手持式中耳分析仪的可靠性、有效性和可行性。
由一名全科医生和一名护士进行两次独立观察的中耳分析测量，并与经过验证的参考仪器进行比较。
美国一所聋人学校的初级保健健康中心。
111名接受定期检查的学童。
使用Grason Stadler 28型进行鼓室导抗测量，并采用略有修改的耶格分类法进行分类。
观察者间可靠性为0.95（科恩kappa系数）。中耳分析测量结果与参考仪器的结果高度可比（阳性结果的似然比为161.2）。
该中耳分析仪可用于一般临床实践：它是手持式的，对儿童友好，易于操作且准确。
