Twenty-three children with Down's syndrome, aged between 3.7 and 17.5 years, underwent partial glossectomy for improvement of cosmetic appearance. Improved speech was also expected. Preoperative and postoperative audiotaped samples of spoken words and connected speech on a standardized articulation test were rated by three lay and three expert listeners on a five-point intelligibility scale. Five subjects were eliminated from both tasks and another four from connected-speech testing because of inability to complete the experimental tasks. Statistical analyses of ratings for words in 18 subjects and connected speech in 14 of them revealed no significant difference in acoustic speech intelligibility preoperatively and postoperatively. The findings suggest that a wedge-excision partial glossectomy in children with Down's syndrome does not result in significant improvement in acoustic speech intelligibility; in some patients, however, there may be an aesthetic improvement during speech.
23名年龄在3.7岁至17.5岁之间的唐氏综合征患儿接受了部分舌切除术以改善外观。预计言语能力也会得到改善。在一项标准化的清晰度测试中，术前和术后的口语单词和连贯言语的录音样本由三名普通听众和三名专家听众按照五点可懂度量表进行评分。由于无法完成实验任务，有5名受试者在两项任务中均被排除，另有4名受试者在连贯言语测试中被排除。对18名受试者的单词评分和其中14名受试者的连贯言语评分进行统计分析后发现，术前和术后的声学言语可懂度没有显著差异。研究结果表明，唐氏综合征患儿的楔形切除部分舌切除术不会导致声学言语可懂度的显著改善；然而，在某些患者中，说话时可能会有美学上的改善。
