Purpose We aimed to investigate the surgical outcomes and clinical performance of an active osseointegration implant system that uses piezoelectric technology. Methods This national, multicenter, prospective, repeated measures study was approved by Ethics Committee (opinion no. CEISH 0559-2019). The sample included patients with conductive hearing loss (CHL), mixed (MHL), or single-sided deafness (SSD) who were eligible for osseointegrated surgery. Surgical parameters assessed, along...
Objective: Tinnitus is often related to auditory dysfunction. We hypothesised that, among individuals with normal thresholds, the mechanism of frequency selectivity might differ between subjects and without tinnitus. Our objective was identify any differences normal-hearing tinnitus those in terms psychophysical tuning curves (PTCs) threshold-equalising noise (TEN) test results. Design: determined PTCs performed TEN test. Study sample: evaluated 57 individuals, 16 bilateral (tinnitus-group)...
Introduction Severe neonatal hypoxia (as evidenced by the Apgar value) is currently considered only risk for hearing loss. Hypoxia one of most common causes injury and cell death. The deprivation oxygen in mild or moderate cases hypoxia, although smaller, occurs could cause damage to auditory system. Objective To investigate amplitude otoacoustic emissions neonates at term with no Methods We evaluated 37 newborns, divided into two groups: a control group 25 newborns without study 12 hypoxia....
Introduction Bone-conduction hearing device (BCHD) uses natural sound transmission through bone and soft tissue, directly to the cochlea, via an external processor that captures processes sound, which is converted into mechanical vibrations. Key parameters, as maximum power output (MPO) broader frequency range (FR), must be considered when indicating a BCHD because they can decisive for speech recognition, especially under listening challenge conditions. Objectives Compare performance...
Speech recognition in noisy environments is a challenge for both cochlear implant (CI) users and device manufacturers. CI manufacturers have been investing technological innovations processors researching strategies to improve signal processing design better aesthetic acceptance everyday use.This study aimed compare speech using off-the-ear (OTE) behind-the-ear (BTE) processors.A cross-sectional was conducted with 51 recipients, all of the BTE Nucleus 5 (CP810) sound processor. perception...
RESUMO Introdução O desempenho auditivo para sons supraliminares pode estar comprometido, mesmo quando o audiograma é normal. Pacientes com zumbido sem perda auditiva queixam-se frequentemente de dificuldades compreensão fala, principalmente em ambientes ruidosos. Objetivo Investigar testes fala ruído, indivíduos limiares audiométricos normais, e queixa zumbido. Métodos Foram avaliados 20 sujeitos adultos, idade entre 18 45 anos, audição dentro dos padrões normalidade, que apresentavam, ou...
Introduction: Studies have shown that individuals with tinnitus show worse speech-in-noise test results than do without tinnitus. An overall reduction in OAE levels has also been reported the former group of individuals, confirming presence outer hair cell dysfunction. Recently, some studies inner dysfunction and adjacent neurons such individuals. The possibility is related to cochlear changes, specifically impaired function, led us hypothesize among normal auditory thresholds, mechanism...
To analyse the results of children and adults with cochlear implants (CIs) in pure tone audiometry (PTA) speech perception tests. Tests were performed two ways: using loudspeakers sound booth (SB) direct audio input (DAI) employing Cochlear Latin America BOX (CLABOX).Fifty individuals (33 17 children) participated study, including aged between 8 13 years; these, 15 users had bilateral CIs, 35 unilateral all severe to profound sensorineural hearing loss. All participants evaluated SB CLABOX...
