A Comparison of Audiometry and Audiometry With Tympanometry to Determine Middle Ear Status in School-Age ChildrenNorma J. Yockel, RN, MSN, SNP, has been employed as a school nurse by the Irvine Unified School District for the past 21 years. She is assigned to an elementary school and a special-education pre-school Otitis media with effusion is the most common cause of fluctuating hearing loss in children. Pure-tone audiometry is the current mandated standard to determine hearing loss in public-school children in most states. Students who fail pure tone audiometry are at risk for otitis media with effusion because it is asymptomatic. Tympanometry, which assesses middle ear status, is used to detect hidden otitis media with effusion. This longitudinal study evaluated pure tone audiometry and tympanometry in preschool and elementary children (n = 141). Results found 12 children (23 ears) who failed either a second threshold or tympanometry. The study also showed that a greater number of ears were identified with otitis media with effusion (n = 19) by using pure tone audiometry and tympanometry than by using pure tone audiometry alone (n = 4).
