Article Synopsis
- Endolymphatic hydrops is linked to Ménière’s disease and can be assessed through wideband tympanometry, which measures acoustic absorbance in the middle ear to detect early changes.
- The study aimed to compare the acoustic absorbance behaviors of symptomatic and asymptomatic Ménière’s patients against healthy controls using tympanometry at different pressures.
- Results showed significant differences in peak pressure and absorbance values between the groups, indicating that wideband tympanometry can effectively identify Ménière’s disease and differentiate between asymptomatic and symptomatic conditions.
Introduction: Tympanometry is currently the most frequently used tool for assessing the status of the middle ear, commonly assessed using a single 226Hz tone. However, the use of the Acoustic Immittance Measures with a wideband stimulus is a promising high-resolution evaluation, especially in individuals known to have middle ear alterations, such as Down syndrome patients.
Objective: The aim of this study was to analyze the acoustic absorbance measurements in children with Down syndrome.
Effect of passive smoking on auditory temporal resolution in children.
Int J Pediatr Otorhinolaryngol
June 2017
Objective: To determine the effect of passive smoking on auditory temporal resolution in primary school children, based on the hypothesis that individuals who are exposed to smoking exhibit impaired performance.
Design: Auditory temporal resolution was evaluated using the Gaps In Noise (GIN) test. Exposure to passive smoking was assessed by measuring nicotine metabolite (cotinine) excreted in the first urine of the day.
Tobacco smoke exposure during childhood: effect on cochlear physiology.
