Objective : This study was to evaluate the result of cochlear implantation in Thai pediatric patients from
1999-2003.
Design : A prospective, open-labeled study.
Setting : University teaching hospital.
Materials and Methods : Long term surgical and audiologic results comparison after cochlear implantation in
2 cases with Mondini anomality, 7 normal cochlea cases and a case of post meningitis post lingual child.
Main out come measures: Speech perception tests battery.
Results : Among 10 children, 8 were implanted with Nucleus 22/24; the other two were implanted with Med-
el device system. 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.
