Resumen

RIBALTA L, Gloria et al. Cochlear implant program results in Clinica Las Condes 20 years since the beginning: Clinical series 1994-2015. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2018, vol.78, n.3, pp.275-280. ISSN 0718-4816.  http://dx.doi.org/10.4067/s0717-75262018000300275.

Introduction:

Sensorineural hearing loss is the third leading cause of disability in Chile, with incidence in infants 1 to 3 cases per 1,000 newborn and prevalence in adult up to 70%, with many cases that can be treated with cochlear implant.

Aim:

to describe outcomes of our series of patients undergoing cochlear implant surgery at Clinica Las Condes (CLC).

Material and method:

Retrospective longitudinal cohort study, 237 patients implanted in our center since 1994 to 2015 were analyzed.

Results:

237 patients, 106 women (44.7%) and 131 men (55.3%) received a cochlear implant during this period. 65.5% of patients were implanted between 2-6 years of age. The most common etiologies were; non-syndromic congenital deafness (45.9%), late genetic onset (11.8%) and meningitis (11.4%). A significant association between the average pure tone average and presence of cochlear malformation (p =0.008) was demonstrated. Only 9.9% of patients had other disabilities associated with hearing loss. Re-implantation rate was 16.3% and only the variable cochlear malformation was associated to it (p =0.016)

Conclusions:

The cochlear implant provides clear benefits to patients with hearing impairment who do not benefit from other hearing devices offering the possibility of social and labor reintegrating, with low surgical risk and high success rate.
