广西壮语腭裂儿童腭咽闭合情况及语音清晰度分析

摘要

Objective To evaluate velopharyngeal closure situation in children with postoperation of the cleft palate who speak Guangxi Cuengh language using nasopharyngeal fiberscope( NPF) and analyse the rate of velopha-ryngeal incompetence( RVPI) , detect speech intelligibility( SI) and observe the situation of speech improvement after cleft palate surgery and to give target treatments for improving the level of cleft palate treatment.Methods Twenty children with cleft palate(10 boys, 10 girls, 3~6 years) who speak Cuengh language were divided into two groups. They were examined using NPF respectively after 3 or 6 months′operation.Velopharyngeal closure function was re-corded respectively when pronounced a, e, i, o, u, w or not.SI was analyzed.Results The children who pro-nounced the cuengh( a, e, i, o, u, w) after 6 months,training had significantly lower RVPI( a, e, i, o, u, w) than they did after 3 months, training(P<0.05).Compared with preoperative SI, the postoperative SI was significantly different(P<0.001).There was no obvious difference of SI between 3 and 6 months after the operation(P>0.05). Conclusion With systemic speech trainings and effective human interventions, the RVPI and SI could be improved to some extents for children with cleft palate.%目的：应用鼻咽纤维镜（ NPF）客观评价广西壮语腭裂患儿术后腭咽闭合情况，分析腭咽闭合不全率（ RVPI）和检测语音清晰度（ SI），观察腭裂术后语音改善情况，从而进行针对性治疗，提高腭裂治疗水平。方法选择3～6岁以壮语为母语的壮族腭裂儿童20例，男10例，女10例，于术后3、6个月分别进行NPF检查，记录静止时腭咽状态和发a、e、i、o、u、w音时腭咽闭合情况，并进行语音清晰度对比分析。结果患儿发a、e、i、o、u、w音时，术后6个月的RVPI较3个月时明显降低（ P＜0.05）。术前与术后的SI比较差异有统计学意义（P＜0.001），术后3个月与6个月的SI没有明显差别（P＞0.05）。结论腭裂患儿手术后经系统的语音训练，有效的人工干预，腭咽闭合率和语音清晰度均有一定改善。
