title: Speech intelligibility after partial glossectomy in children with Down's syndrome.
abstract: 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.
