Published: November 2002

Objective: The purpose of this study was to investigate the ECochG in subjects with auditory neuropathy (AN).

Method: The ECochG was recorded from ear canal electrode in patients with auditory neuropathy and normal subjects. The difference of their -SP amplitudes was compared.

Result: The -SP was present in all AN ears and its amplitudes were significantly larger than those in normal subjects (P < 0.01). A low amplitude wave AP was present in 84% AN ears.

Conclusion: The -SP was present in all AN ears and its amplitudes were larger.

Effects of rapid maxillary expansion on auditory thresholds and middle ear functioning.

Codas

January 2025

Instituto de Psicologia, Serviço Social, Saúde e Comunicação Humana, Universidade Federal do Rio Grande do Sul - UFRGS - Porto Alegre (RS), Brasil.

Purpose: To ascertain whether Rapid Maxillary Expansion (RME) elicits effects on the functioning of the middle ear and air-bone gaps in children and adolescents.

Methods: Single-arm clinical trial, with data collection at four time points: before initiating Rapid Maxillary Expansion (RME) (T0), upon completion of RME (T1), three months post-RME completion (T2), and six months post-RME procedure (T3). The audiological assessment, conducted at all four time points, comprised otoscopy, pure tone and speech audiometry, tympanometry, and acoustic reflex investigation.

Background: Binaural beat is created by presenting two different pure-tone sine waves with less than a 30Hz difference dichotically. In dental settings, children listening to familiar music during treatments gain control over the anxiety caused by tools like the airotor or syringe, creating a comforting, familiar environment.

Aim: To evaluate and compare anxiety level during restorative treatment using No Music, Music of choice and Binaural Auditory Beats as Audio distraction behaviour guidance technique in children aged 6-12 years.

Treacher Collins syndrome (TCS) is an uncommon congenital disorder predominantly involving craniofacial, orbital, and otological structures. The various ear malformations seen in 9 patients with TCS are described. TCS predominantly affects the external and middle ear structures, with inner ear structures being relatively spared, not unexpected given the dual embryological origin of the human ear.

Purpose: Repetitive transcranial magnetic stimulation (rTMS) is a potentially effective, noninvasive tool for language mapping. However, there is a paucity of data in pediatric patients. In this study, we aimed to map language sites in healthy pediatric participants with navigated rTMS.

Machine-Learning Predictions of Cochlear Implant Functional Outcomes: A Systematic Review.

Ear Hear

January 2025

San Francisco Department of Otolaryngology - Head and Neck Surgery, University of California, San Francisco, California, USA.

Objectives: Cochlear implant (CI) user functional outcomes are challenging to predict because of the variability in individual anatomy, neural health, CI device characteristics, and linguistic and listening experience. Machine learning (ML) techniques are uniquely poised for this predictive challenge because they can analyze nonlinear interactions using large amounts of multidimensional data. The objective of this article is to systematically review the literature regarding ML models that predict functional CI outcomes, defined as sound perception and production.
