The goal of this observational study is to describe the type of the rehabilitation method for italian children with cochlear implant . The main questions are:

What is the most used rehabilitation methods in implanted children? Which is the prevalence of each method related to the clinical features of the patients?

The cochlear implant represents the gold standard in the treatment of children with bilateral severe-profound deafness. However, the current Italian and international guidelines do not address the issue of rehabilitation and how the different rehabilitation methods should be applied in relation to the different clinical pictures. The aim of this study is therefore to describe which methods are used today in the rehabilitation of deaf children with cochlear implants followed at the Phoniatrics and Speech Therapy service of the A. Gemelli Polyclinic Foundation. The creation of a questionnaire directed to the speech therapist who treats the specific patient is available in order to collect data concerning the characteristics of the setting and the rehabilitation method in relation to the most applied methodologies, i.e. Auditory-verbal therapy, oral-cognitive therapy, bimodal method and the Drežančić method.
