PURPOSE To evaluate and compare the workers' perception of comfort and use aspects regarding two types of hearing protectors (shell and earplug), in three units from a lumbering company, with different implantation times for Hearing Preservation Programs. METHODS This is a cross-sectional study comparing 440 workers' perception of hearing protectors, from three companies in Paraná State (Braz...

OBJECTIVE Partial deafness cochlear implantation and electric-acoustic stimulation have proven to be a useful method of treating adults with a ski-slope type hearing loss. Good hearing preservation and speech perception outcomes have been reported. This study aims to assess partial deafness cochlear implantation in children. METHOD Nine children, ranging in age from 4.2 to 12 years, received ...

OBJECTIVE The objective is to perform a systematic review and meta-analysis of the literature on the long-term results of hearing preservation after vestibular schwannoma resection. DATA SOURCES Ovid/Medline, PubMed, Embase, and the Cochrane library from January 1980 to January 2015. STUDY SELECTION Inclusion criteria: age ≥18 years, minimum 10 patients in the treatment group, hearing prese...

Cochlear implantation is now being performed in ears with residual hearing. Those implant recipients who keep residual hearing may benefit from improved pitch resolution through both electrical and acoustic hearing. Preservation of cochlear function after implantation is a challenging task for the surgeon. Current topics of hearing preservation research include electrode design and surgical tec...

This paper provides a review of the current literature on psychophysical properties of low-frequency hearing, both before and after implantation, with a focus on frequency selectivity, nonlinear cochlear processing, and speech perception in temporally modulated maskers for bimodal listeners as well as patients with hearing preservation in the implanted ear and receiving combined electric and ac...
