Abstract

Prior to this investigation, there appeared to be no published research data available on tympanometric configurations obtained from an older adult population. This study was designed to examine tympanograms obtained from an otologically normal, elderly population. Forty individuals, ranging in age from 59 to 83 years, participated in this study. All had a negative history of middle ear pathology and had normal tympanic membranes as determined by otologic examination. From the eighty ears tested, fifty were used in this survey. Conductance and susceptance at 220 and 660 Hz were obtained at each ear and ranges for admittance were computed from these components. Additionally, acoustic reflex thresholds were obtained from this population.

The results obtained indicate that the values for the measures of conductance and susceptance are comparable to those from young adult groups. The reflex thresholds are slightly higher in the older group because their hearing thresholds are not as acute as those found in younger populations. Finally a larger percentage of the older population than might be expected was found to have evidence of healed perforations which were not discovered during otoscopic examination.

The present investigation demonstrated that additional normative data are neededin order that the otoadmittance meter be fully utilized with older adult populations.
