Abstract:
Objective To study the outcomes of two intervention strategies on the language development of young children with hearing loss greater than moderate degree by universal newborn hearing screening (UNHS) system.Methods Infants and young children,born from Jan 2002 to Dec 2007 in Shanghai and failed UNHS,were included in this study.They received audiometric evaluations at the Shanghai Children's Hearing and Speech Center.Among those diagnosed with hearing loss greater than moderate degrees,65 were intervened at 6 months and followed up subsequently.According to hearing loss degree and intervention strategies,20 of 65 were included in the hearing aid group(M_(HA)),19 was in the severe hearing aid group(S_(HA)),9 in the profound hearing aid group(P_(HA)),and 17 in the profound cochlear implamation group(P_(CI)).Other 36 were not intervened at 6 months old but followed up also.The control group was 36 normal hearing young children.The hearing losse and speech development were analyzed for statistical study.Results Between the group without intervention and the control group,between the group intervened and without intervention,statistically significant differences were noted (P＜0.05) in the average hearing threshold and the developmental scores.Between the control group and anyone group among M_(HA),S_(HA) and P_(CI),no statistically significant differences (P＞0.05) were noted in the developmental scores.For the same hearing level between the group P_(HA) and P_(CI),statistically significant differences (P＜0.05) were noted in the developmental scores.The developmental scores of P_(HA) was lower than that of P_(CI).Conclusion Early intervention is effective for infants and young children with hearing loss greater than moderate degree.Their speech development is noticeably faster than that of those without any intervention.According to hearing loss degree,it was very important for acquiring the best speech development that selected the most proper intervention mode.
