RESUMO

Meningitis is one of the most common causes of acquired profound sensori-neural hearing loss in developing countries. Literature has provided contradictory data with regard to the outcome of cochlear implantation in post-meningitic adult patients. Objective: To review the outcome of cochlear implantation in adult patients with sensorineural hearing loss whose etiology was meningitis, to try to identify the factors that could influence the results. Material e methods: Twenty-nine adult patients with postmeningitis deafness submitted to cochlear implantation between 1990 and 2001 at the Craniofacial Anomaly rehabilitation Hospital in Bauru, São Paulo, Brazil were studied retrospectively. The results of this group were compared to a control group consisting of 28 patients with etiologies other than meningitis. ResuIts: Partial ossification of the cochlea was observed in 69 % of the patients in the post-meningitic group. In this group, partial insertion occurred in 41 % of the patients compared to 7 % in the control group. Open-set speech recognition occurred in 82% versus 89% in the control group. There were 6 surgical complications in the meningitic group, all of which occurred in patients with partially ossified cochleas. Five of the six complications were simple and handled with minor procedures. ConcIusion: In our study, the ossified cochlea, which occurred in postmeningitic group, negatively influenced the number of partial insertions and augmented the number of complications when compared with the control group, however apparently did not influence the auditory results. The hearing results were satisfactory and equivalent in both groups
