Background: Cochlear implantation is an effective method of auditory rehabilitation. Nevertheless, the results show individual variations depending on several factors.
Aim: To evaluate cochlear implantation results based on the APCEI profile (Acceptance, Perception, Comprehension, Oral Expression and Intelligibility) and audiometric results.
Methods: This was a cross-sectional study including children under 18 years of age who had a unilateral cochlear implant and whose implants had been activated at least 1 year prior to the start of the study. During this study period, 75 children underwent unilateral cochlear implantation. Among them, 44 patients had reached one year after the activation of the implant at the time of the evaluation and were then included in the analytical part. A speech-language pathology assessment using the APCEI scale was conducted for 44 cases. Thirty-eight cases had an audiometric assessment (free-field tone audiometry and speech audiometry). We assessed the results of the APCEI profile based on various factors.
Results: The mean cochlear implantation age was 5 years and 2 months. The electrode insertion was complete in all cases. The APCEI profile average was 3.6. Four children had poor results, 27 children had good results, and 13 children had excellent results. The average hearing threshold in tonal audiometry was 39dB. In voice audiometry, the average intelligibility threshold was 65% with the cochlear implant versus 75% with the cochlear implant and the contra lateral hearing aid. According to the statistical study, only two factors were considered to have a positive influence on the success rate of cochlear implantation: the regular use of preoperative amplificative prostheses and the follow-up of speech therapy sessions in pre-operative.
Conclusion: The effectiveness of cochlear implantation depends on several factors. Multidisciplinary management improves the results.

Purpose: Cochlear implantation (CI) surgery is essential for restoring hearing in individuals with severe sensorineural hearing loss. Accurate placement of the electrode within the cochlea is essential for successful auditory outcomes and minimizing complications. This study aims to analyze the relationship between the round window niche (RWN) alignment, its visibility during surgery, and the impact on surgical techniques and outcomes.

Objective: This review aims to analyse the implications of the World Health Organization's 2021 world report on hearing, with a particular focus on the cochlear implant field. The objective is to understand the challenges and opportunities highlighted in the report and propose viable solutions for effective implementation within the cochlear implant community.
Methods: Following the release of the World Health Organization's world report on hearing, cochlear implant professionals explored and discussed the implications of the report with examples from various countries to understand the disparities in access, reimbursement policies, and social stigma associated with hearing loss.

Department of Otolaryngology, China-Japan Friendship Hospital, Beijing, China.
Objectives: This study examined the relationships between electrophysiological measures of the electrically evoked auditory brainstem response (EABR) with speech perception measured in quiet after cochlear implantation (CI) to identify the ability of EABR to predict postoperative CI outcomes.
Methods: Thirty-four patients with congenital prelingual hearing loss, implanted with the same manufacturer's CI, were recruited. In each participant, the EABR was evoked at apical, middle, and basal electrode locations.
Background: Cochlear implantation is an effective method of auditory rehabilitation. Nevertheless, the results show individual variations depending on several factors.
Aim: To evaluate cochlear implantation results based on the APCEI profile (Acceptance, Perception, Comprehension, Oral Expression and Intelligibility) and audiometric results.
Objective To develop an algorithm, based on the voltage matrix, for detecting regular cochlear implant (CI) electrode position during the implantation procedure, tip fold-over or basal kinking for lateral-wall electrodes. The availability of an algorithm would be valuable in clinical routine, as incorrect positioning of the electrode array can potentially be recognized intraoperatively. Design In this retrospective study intraoperative voltage matrix and postoperative digital volume tomography of 525 CI recipients were analyzed.
