AI Article Synopsis
Article Abstract
Objectives: To report the status and outcomes of cochlear implantation in Thailand.
Design: Cohort study.
Setting: Tertiary care and university hospitals.
Participants: Patients who underwent cochlear implant surgery in Thailand.
Interventions: This project collected data from all government and university hospitals in Thailand where cochlear implant surgery was performed between 2016 and 2020.
Primary And Secondary Outcome Measures: Baseline characteristics, operation data, complications, audiological outcomes and quality of life were reported.
Results: This study included 458 patients, and nearly half of the patients were children and adolescents (46.94%). The mean age of the patients was 2.96±5.83 years. At 1 year postoperatively, the mean pure tone average of the hearing threshold in the implanted ear significantly improved from unaided preoperative baseline (mean difference (MD) 64.23 dB HL; 95% CI 59.81 to 68.65; p<0.001). The mean speech recognition threshold also improved (MD 55.96 dB HL; 95% CI 49.50 to 62.42, p<0.001). The quality-of-life scores of the EQ-5D-5L, PedsQL and HUI3 questionnaires at 1 year showed improved mobility (range, 0-5; MD 0.65; 95% CI 0.05 to 1.25; p=0.037), hearing (range, 0-6; MD 0.96; 95% CI 0.30 to 1.61; p=0.006) and speech (range, 0-5; MD 0.44; 95% CI 0.04 to 0.84; p=0.031). Common complications included electrode dislodgement (2.18%), vertigo (1.23%) and meningitis (1.93%).
Conclusions: Excellent audiological outcomes and improvement in the quality of life in the mobility, hearing and speech domains were observed in patients who underwent cochlear implantation in Thailand.

Establishment of quantitative evaluation system for cochlear implant effectiveness for hearing-impaired children.
J Otol
April 2024
Department of Otolaryngology-Head and Neck Surgery, Renmin Hospital of Wuhan University, 238 Jie-Fang Road, Wuhan, Hubei, 430060, China.
Introduction: Cochlear implant is currently the most widely proven interventions for auditory rehabilitation for children with severe sensorineural hearing impairment. However, there are obvious limitations in these current evaluation methods. This study aims to develop an evaluation system for quantitatively evaluating the effectiveness of cochlear implants for hearing-impaired children.

Introduction: Wolfram syndrome, a rare autosomal recessive disorder, is characterised by diabetes insipidus, juvenile diabetes mellitus, optic nerve atrophy and deafness (DIDMOAD).
Case Report: We present a case of a 21-year-old male diagnosed with Wolfram syndrome who underwent cochlear implantation due to progressive hearing loss. The patient first complained of bilateral hearing loss at the age of 8 years.
Auditory brainstem response thresholds and functional hearing: implications for cochlear implant candidacy.

Department of Otorhinolaryngology, Head and Neck Surgery, Antwerp University Hospital (UZA), Edegem, Belgium.
Objective: This study assessed the relevance of auditory brainstem response (ABR) thresholds in evaluating cochlear implantation (CI) candidacy by studying their correlation with functional hearing in patients with sensorineural hearing loss (SNHL).
Design And Study Sample: In this retrospective study, we examined correlations between ABR thresholds, speech perception scores in quiet and pure-tone audiometry in 191 adults. We compared these correlations between individuals with different degrees of SNHL to discern differences in potential CI candidates and individual with less severe SNHL.
Auditory and Speech Outcomes Following Transcutaneous Bone Conduction Hearing Implantation.

Otolaryngology- Head and Neck Surgery, King Abdulaziz University Faculty of Medicine, Jeddah, SAU.
Objectives: Implantable bone conduction hearing devices offer excellent auditory rehabilitation. Transcutaneous devices, which use an implanted magnet, are gaining popularity due to higher skin complications associated with traditional percutaneous devices. The Cochlear Baha® Attract System (Cochlear Corporation, Sydney, Australia) is a transcutaneous device and is regarded as a passive transcutaneous implant.

Objectives: This experimental study compares the precision and surgical outcomes of manual versus robotic electrode insertions in cochlear implantation.
Methods: Conducted on formalin-fixed cadaveric heads, the study involved nine senior neurotologists performing both manual and robotic insertions.
Results: The results showed no statistically significant difference between the two methods in insertion angle, cochlear coverage, or electrode coverage.
