Introduction: Auditory performance and language proficiency in young children who utilize auditory brainstem implants (ABIs) throughout the first 3 years of life are difficult to predict. ABI users have challenges as a result of delays in language proficiency and the acquisition of reading comprehension, even if ABI technology offers auditory experiences that enhance spoken language development. The aim of this study was to evaluate about the impact of language proficiency on reading comprehension skills in children with ABI.

Introduction: For a comprehensive approach in children with hearing loss (HL), some cognitive and language skills should also be considered, along with auditory skills. The main aim of this study was to evaluate the working memory and language skills in children with mild to moderate HL.

Methods: Forty children with mild to moderate HL between the ages of 4 and 9 years were included in this study.

Article Synopsis
  • - The study focuses on patients with incomplete partition type II (IP-II) malformation and large vestibular aqueduct (LVA), examining their hearing loss (HL) and the need for auditory rehabilitation (AR) solutions.
  • - Out of 55 patients, cochlear implants were used by 29.1%, hearing aids by 43.6%, and bimodal applications by 27.3%, with no significant differences found in dizziness, tinnitus, or HL progression.
  • - Findings show varied audiological characteristics in patients with IP-II and LVA, highlighting hearing aids as the most common AR method, but predicting the type of HL progression remains difficult and should be approached cautiously.

The just-noticeable differences (JNDs) of the voice cues of voice pitch (F0) and vocal-tract length (VTL) were measured in school-aged children with bilateral hearing aids and children and adults with normal hearing. The JNDs were larger for hearing-aided than normal-hearing children up to the age of 12 for F0 and into adulthood for all ages for VTL. Age was a significant factor for both groups for F0 JNDs, but only for the hearing-aided group for VTL JNDs.

Article Synopsis
  • The study investigated the effects of cochlear implants (CIs) on speech recognition and quality of life in postlingually deaf adults who had been deaf for over 25 years.
  • A total of 54 participants underwent assessments before and three years after receiving CIs, focusing on speech recognition and hearing-related quality of life.
  • Results showed a significant negative relationship between duration of deafness and speech recognition scores, emphasizing the importance of early CI intervention to prevent auditory pathway degeneration.*

Purpose: The purpose of this study was to (a) investigate which speech material is most appropriate as stimulus in head shadow effect (HSE) and binaural squelch (SQ) tests, (b) obtain normative values of both tests using the material decided to be optimal, and (c) explore the results in bilateral cochlear implant (CI) users.

Method: Study participants consisted of 30 normal-hearing (NH) persons and 34 bilateral CI users. This study consisted of three phases.

The aim of this study is to develop the Turkish version of hearing in noise test for children (HINT-C) by providing norms and correction factors for the children in different age groups. A total of 77 individuals with normal hearing - 62 children (6-12 years old) and 15 adults (18-30 years old) - were included. Twelve phonemically balanced 10-sentence lists were created from the adult version of the Turkish HINT (Study 1).

Objectives: After auditory brainstem implant (ABI) surgery, stimulation of certain cranial nerves may result in a non-auditory response, and the electrodes that stimulate these nerves may be deactivated. The goals of this study are to compare the number of active electrodes in the initial activation and the last fitting, to investigate non-auditory response types and their frequency as a result of non-auditory stimulation, to compare the placements of deactivated electrodes as a result of non-auditory stimulation in the initial activation and the last fitting.

Methods: The computer software system was used to perform a retrospective analysis of the fitting data of 69 ABI users who underwent auditory brainstem implant surgery between January 1997 and January 2019.

Background: Mothers' awareness of hearing loss, its risk factors, and available detection and intervention choices have been well known to play an essential role in the early detection and intervention of hearing loss.

Objective: To investigate the knowledge and attitude of Syrian mothers toward infant hearing loss, early identification, and intervention.

Methods: The "Maternal Views on Infant Hearing Loss" questionnaire was adapted and translated into Arabic and then administered to 100 Syrian mothers living in different neighborhoods in Ankara within the age range of 18-68 years old.

Objectives: The objectives of this study were to assess auditory perception and speech intelligibility outcomes in children with cochlear nerve (CN) hypoplasia who received cochlear implants (CIs) using Categories of Auditory Performance II (CAP II) and Speech Intelligibility Rating (SIR) scales.

Methods: In total, 40 children who received CI and who were aged between 3 and 18 years were included in this study. The study group included 20 children with CN hypoplasia at least one ear, while the control group included 20 children with normal cochleas and cochlear nerve structures.

Objectives: To assess the quality of life (QoL) in child and adolescent cochlear implant users with inner ear malformations (IEM) and to compare their outcomes to their cochlear implant using peers with normal inner ear structures.

Methods: The present sample consisted of 100 children (45 with IEM, 55 without IEM) and 100 adolescents (46 with IEM, 54 without IEM).

Article Synopsis
  • The study aimed to assess cochlear implant (CI) mapping parameters in users with inner ear malformation (IEM) and examine changes over time compared to those with normal cochlear anatomy.
  • A total of 118 CI users were analyzed at various time points post-surgery, focusing on parameters like impedance measurements, threshold levels (THR), most comfortable levels (MCL), pulse width (PW), and rates.
  • Results indicated significant differences in several mapping parameters between IEM users and control groups over time, suggesting that pediatric CI users with IEM require individualized fitting adjustments and more frequent mapping sessions.
