DIAZ S, Constanza et al. Language development in children with cochlear implant at a tertiary health care center: Clinical series. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2018, vol.78, n.4, pp.343-352. ISSN 0718-4816.


Since the 90s, cochlear implantation has progressed from experimental to standard clinical practice for children with severe and profound hearing loss. Research has produced changes in implant technology and has led to the expansion of implant candidacy to include children younger than 2 years of age. The primary goal of pediatric cochlear implantation is to facilitate spoken language development. Despite the advances in implant technology and the changes to the management of hearing loss, language outcomes for children are still highly variable, participating in this process both timely treatment, the family network and socio economic level among others.


describe outcomes of patients younger than 6 years undergoing cochlear implant surgery in a tertiary care center.

Material and method:

retrospective longitudinal cohort study, 99 patients implanted in a tertiary health center since the program's inception in 1994 to 2015 was analyzed.


99 patients, 57 % men 43 % women, average age of implantation 16.3 months. 54.8 % of cases were congenital or prematurity. In 74.4 % they had auditory verbal language. Socioeconomic status (SES) showed association with the lack of language development (p =0.009) demonstrating that low SES patients (20%) do not develop language. The disability associated variable (p <0.001) and the SES variable (p =0.036) were independently associated with sign language or no oral language development.


Cochlear implants offer an option for hearing rehabilitation in profound hearing loss, for candidates of all ages, however the results depend largely on the environment in which cochlear implants are used.
