The pre-operated cochlea in 2 cases showed Mondini deformity both had gushers during the operation with a good outcome. The other 8 cases had normal cochlea although one was deaf from bacterial meningitis. There were 3 re-implantations. Speech production and perception was improved faster in the two children implanted with Med-el than those implanted with Nucleus devices.Conclusion: Cochlear implantation in Mondini cases can be successful in speech production and perception. Speech perception ability depended on the age of implantation and preoperative rehabilitation.
