Abstract
OBJECTIVE: To determine the reliability, validity, and feasibility of a new hand held microtympanometer. DESIGN: Comparison of microtympanometry by two independent observations of a general practitioner and a nurse, and against a validated reference instrument. SETTING: Primary care health centre of a school for the deaf in the United States. SUBJECTS: 111 schoolchildren receiving a regular check up. MAIN OUTCOME MEASURES: Tympanometry with the Grason Stadler 28, classified with a slightly modified Jerger's classification. RESULTS: 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). CONCLUSIONS: The microtympanometer could be used in general practice: it is hand held, child friendly, easy to handle, and accurate.
