OBJECTIVE To reframe the criteria for pediatric cochlear implants (CIs) in Japan, we investigated monosyllabic and word speech perception at the time of school entry in deaf or hard of hearing (D/HH) children who underwent auditory-verbal therapy (AVT) with hearing aids (HAs) or CIs in early childhood. METHODS D/HH children who started AVT at Fujimidai Auditory Center for Hearing-Impaired Children before the age of 1 year and who underwent auditory assessment in the previous year of schooling (at the age of 5 or 6) from 2010 to 2020 were enrolled in this study. The results of hearing level tests with or without amplification and monosyllabic and word speech discrimination were assessed. RESULTS The children with profound hearing impairment (>90 dB HL) had worse speech perception than children with CIs. The children with severe hearing impairment (>70-90 dB HL) did not show any significant differences in speech perception compared with the children with CIs. The children with HAs with a wearing threshold <40 dB HL did not show any significant differences in speech perception from the children with CIs. CONCLUSIONS D/HH children with audiologic thresholds greater than 90 dB HL or aided thresholds greater than 40 dB HL should be considered for CIs to ensure development of appropriate listening and spoken language.
