Background: Cochlear implants (CI) are nowadays a widely accepted treatment for sensorineural hearing loss SNHL.
Aim: This study aimed to describe the epidemiological characteristics and the surgical approach and to evaluate the outcomes of our experience in cochlear implantation.
Setting: Department of Otolaryngology-Head and Neck Surgery of University Hospital Mohammed VI Marrakech Morocco.
Methods: A retrospective chart review was conducted on 113 patients with severe to profound hearing loss who underwent a cochlear implantation between 2007-2018.
Results: There were 65 females and 48 males with severe to profound bilateral deafness, of whom 103 had prelingual deafness. The mean age of pediatric cochlear implantation was 5.25 years. Implantation was unilateral in all patients. The procedure was followed by regular adjustments and speech therapy. The evaluation was carried out by the same team each month during the first 6 months, then every 6 months. The average duration of follow-up was 37.54 months. All patients benefited from their implants with inter individual variability.
The good results were correlated with early implantation, significant parental investment and a steady follow-up of speech therapy.
Conclusion: Cochlear implantation has revolutionized the management of severe to profound deafness. It is a safe and effective technique when it is aimed at correctly selected populations.
Levels of electrically evoked stapedial reflex thresholds (eESRTs) are frequently used as most comfortable levels (MCL) in cochlear implant fitting. The problem of routine one-channel-technique of reflexometry is long duration of this procedure. In order to “compress the time” we suggest method of consecutive stimulation of all electrodes of implant with simultaneous registration of stapedial reflexes-SWEEP-session. Practical implementation of the SWEEP-session is described here. This method has been successfully used in several hundred CI patients. Registration of evoked electrical stapedial reflex thresholds (eESRTs) during CI fitting is long procedure. In order to “compress the time” we suggest our SWEEP-session method. Practical implementation of this SWEEP-session is described here in accordance with the patent of Russian Federation.
To facilitate understanding some issues of cochlear implantation for new beginners we wrote 1- “The Instruction for audiologists and cochlear implanted patients” and created 2-Demo-program MIMIC. Here are opinions of readers of “The Instruction” and participants of MIMIC. All the ratings are from positive to enthusiastic.

I, Muhammad Sarwar Khan, am serving as Editor on Archives of Biotechnology and Biomedicine (ABB). I submitted an editorial titled, 'Edible vaccines to combat Infectious Bursal Disease of poultry' for publication in ABB. After submitting the manuscript; the services rendered by the management and technical personnel to handle and process the manuscript were marvelous. Plagiarism report was shared with me with complements before reviewers' comments, All steps including article processing and service charges were well taken care of keeping in view the author's interest/preference. All together, it was an encouraging and wonderful experience working with ABB personnel.
