Resumen

PAZ-CORDOVEZ, Antonio Simeón et al. Cochlear implants: priority for children with dual sensory loss in Cuba. AMC [online]. 2021, vol.25, n.4  Epub 01-Ago-2021. ISSN 1025-0255.

Background

: since 2005 the Cuban Cochlear Implant Program for deaf and deaf-blind children has been created, with priority for children with dual sensory loss. Objective: is to describe the work of the Cuban Cochlear Implant Program with children with dual sensory loss.

Methods

: a descriptive, retrospective study of children with dual sensory loss who received a cochlear implant between February 2005 and March 2013 in Cuba. The information to conform this descriptive report was obtained from the clinical histories and the database of the program; it also illustrates the first results on neuroplasticity obtained with the somatosensory evoked potential of the median nerve carried out with part of the pre-cochlear implant research study protocol in the Cuban Cochlear Implant Program.

Results

: the program has benefited 27 children with dual sensory loss with cochlear implants, covering all provinces of the country. Six children presented an associated pathology, with pre/peri-natal factors and Usher Syndrome as the main causal agents of deaf-blindness. Hearing loss was pre-lingual in 24 children, confirmed and characterized by electro-audiometry. No malformations were found in the ear images. The implantation was unilateral, mostly the right ear, without surgical complications in all the children. While the neuroplasticity study shows somesthetic cortical reorganization in children with dual sensory loss.

Conclusions

: the Cuban Cochlear Implant Program has achieved sustained work in the evaluation and implantation of children with dual sensory loss, a distinctive aspect being the research on neuroplasticity, which has provided evidence of somesthetic cortical representation pre-cochlear implantation in these children. This will be useful to assess cortical reorganization post- cochlear implant and correlate it with the use of the cochlear implant.
