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(P<0.05)and there was no statistics significance group of implant age(P>0.05).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.
