Cochlear Implants in Special Cases: Deafness in the Presence of Disabilities and/or Associated Problems

The aim of the present study is to construct a reference model with the indication for the attitude, the requirements and the resources needed in order to be able to deal with deafness in the presence of disabilities or associated problems. The study group consisted of 13 adults and 18 children affected by profound deafness, with associated problems and disabilities, who were implanted with Clarion® and Med-El® devices. Selection criteria for candidacy to cochlear implantation and counselling, hospitalization, fitting and speech therapy/rehabilitation are described. Findings were assessed evaluating: (i) use of acoustic feedback, on the ground of Erber's model; (ii) self-sufficiency: assessed by a questionnaire; and (iii) social and family relationships: qualitative judgment based on direct observation, analysis of drawings and structured interviews with family teachers and therapists. The whole group showed benefit from cochlear implantation, with particular satisfaction for post-lingual deaf-blind adults, as well as for subjects with associated psychopathologies and mental retardation. In conclusion, cochlear implants can improve life quality in profoundly deaf subjects with associated disabilities, increasing both listening and communication skills as well as self-sufficiency while family and social relationships tend to remain stable.
