Introduction: Bacterial meningitis is a known cause of acquired deafness. This may show in different degrees and have inevitable consequences, if not rehabilitated in time. In the rehabilitation of profound deafness, the cochlear implant (CI) has recognized efficacy, but better or worse performances are possible. Some authors suggest that implanted children after bacterial meningitis have less favorable results than those implanted for other causes, including congenital deafness.
Objective: To evaluate the results of the audio - oral performance with CI of children with profound deafness after bacterial meningitis and compare them with the performances of children with congenital profound deafness.
Methods: A retrospective study based upon the population of profound deaf children admitted in the hearing rehabilitation program with CI in Centro Hospitalar de Coimbra E.P.E., between 1993 and 2010. Case revision of children implanted with profound deafness after bacterial meningitis (24 cases) and comparison of results of CI performance (hearing, speech and voice) in deafness by meningitis (in pre- and peri-lingual age) and congenital deafness.
Results: The test results of the audio-oral skills for hearing, speech and voice were similar in both groups of implantation after meningitis and in congenital deafness (p value greater than 0.05 in all tests except the SIR test p = 0.004).
Conclusion: There were no statistically significant differences in tests of audio-oral skills with CI between the 2 studied groups; the performance with CI was similar.
