RESUMO
Objective To study the factors affecting preverbal communication skill in prelingually deaf children with cochlear implants.Methods A total of 31 prelingually deaf children with cochlear implantation participated in the study.They received cochlear implantation the age of 12 months with a mean of 46.71 months.The video analysis were applied to assess the preverbal communication skill including rurn-taking,autonomy,eye contact and auditory awareness.According to the implant age,preoperative use of hearing aids,preoperative speech rehabilitation training,preoperative surgerg ear averrage residual hearing.Wilcoxon signed-rank test was used to evaluate the differences among the groups.The implant age distribution:16 cases in ≤36 months group;15 cases in >36 months group.Preoperative speech rehabilitation training (recovery time more than 3 months) : 14 cases in rehabilitation group, 17 case in no rehabilitation group.Preoperative surgerg ear averrage residual hearing:6 cases in ≤80 dB HL group;25 cases in >80 dB HL group.Preoperative use of hearing aids (use time more than 3 months) distribution: 21 cases in use group, 10 cases in no use group.Results There was statistical signifficance in preoperative use of hearing aids,preoperative speech rehabilitation training,preoperative surgerg ear averrage residual hearing(P0.05).Conclusion Preoperative use of hearing aids,preoperative speech rehabilitation training,preoperative surgerg ear averrage residual hearing in prelingually deaf children with cochlear implants relate with better preverbal communication still.
