The aim of the study was to evaluate the outcomes of cochlear implantation (CI) in a group of immigrant deaf children living in a foreign language family, following up to 3 years of a personalized habilitation program compared to age-matched Italian CI recipients. Tests of speech perception ability such as the IT-MAIS, the LiP, the CAP, and speech production such as the MUSS have been used before CI and then after 6 months, 1 year, 2 years, and 3 years. Nonparametrical tests were chosen for comparison. Eight bilingual CI recipients were included in the study and matched to 11 Italian CI recipients. The difference between chronological age at implantation, age at diagnosis, hearing age, and verbal age in the two groups of children was not significant. Comparison of the auditory perceptive and linguistic abilities between the two groups showed significant differences only in preoperative MAIS and postoperative CAP (1 to 3 years). In agreement with other studies, we achieved good performances from bilingual children with CI and our personal experience confirm the attitude of promoting bilingualism throughout the rehabilitation process.

AbstractObjectives:To investigate the prevalence of mutations in the coding exon of the GJB2 gene in Iranian children with cochlear implants, and to compare the outcomes of auditory perception and speech production in cochlear-implanted children with and without GJB2 mutation.Materials and methods:One hundred and sixty-six prelingually deaf children who had undergone cochlear implantation at the Iranian Cochlear Implant Center, Tehran, were selected from a pool of 428 implanted children. The prevalence of GJB2 gene mutations was assessed using nested polymerase chain reaction and direct sequencing. To enable comparisons, we also identified 36 implanted children with non-GJB2 deafness. Patients' speech perception and speech production were assessed using the Categorization of Auditory Performance and Speech Intelligibility Rating scales.Results:Thirty-three of 166 probands (19.9 per cent) were found to have GJB2 deafness-causing allele variants and were diagnosed with DFNB1 deafness. Results also indicated a significant improvement in speech perception and production scores in both GJB2 and non-GJB2 patients over time.Conclusion:Children with GJB2-related deafness benefit from cochlear implantation to the same extent as those with non-GJB2-related deafness.

The speech perception and speech production performance following cochlear implantation of congenitally deaf children and children deafened by meningitis were analysed. Three groups consisting of 70 congenitally deaf children, 22 children deafened by meningitis before two years of age and 14 children deafened by meningitis after two years of age were compared. The group deafened by meningitis after two years of age demonstrated significantly better speech perception than the other two groups. Their speech production appeared better but did not achieve statistical significance compared with the other two groups. There was no significant difference in either speech perception or speech production between the congenitally deaf group and the group deafened by meningitis before two years of age.
