Wideband absorbance for the assessment of pressure equalizing tubes patency in children

Objectives: To analyze the feasibility of using wideband absorbance to verify the patency of pressure equalizing tubes (PETs) in clinical practice and to present the response pattern of this measure for ears with patent PET. Methods: This observational case-control type study evaluated 48 ears of 30...

Methods: This observational case-control type study evaluated 48 ears of 30 children with severe or profound hearing loss, aged 10–44 months, of both sexes. The subjects were subdivided into two groups: 24 ears with Sheppard type PET (experimental group - EG) and 24 ears with normal middle ear (control group - CG), paired with the EG, according to age, sex, and ear evaluated. To obtain the wideband absorbance, a Middle-Ear Power Analyzer, version 5.0 (Mimosa Acoustics), was used, and absorbance values for pure tone and chirp stimuli were analyzed. Results: There was no influence of ear (right or left) on the measurements obtained. The EG showed higher absorbance values at low frequencies. Although the two stimuli made it possible to identify the difference in acoustic transfer function between the groups studied, compared to pure tone, the chirp stimulus allowed identification of differences in a higher number of frequencies. Conclusions: Ears with a patent PET present an acoustic transfer pattern that differs from that obtained for normal middle ears, with a higher absorbance at low frequencies. Both pure tone and chirp stimuli can be used to identify such differences, nevertheless, the use of chirp stimulus is recommended, since it allows differentiation over a wider frequency range. 2022 2023-05-05T19:31:26Z 2022-09 article ARAUJO, Eliene Silva; JACOB, Lilian Cassia Bornia; OLIVEIRA, Maria Taiany Duarte de; CHAVES, Juliana Nogueira; OLIVEIRA, Eduardo Boaventura; SATERS, Thais Lenharo; ALVARENGA, Kátia de Freitas.
