摘　　要：目的:研究儿童腺样体切除术对腭咽闭合功能的早期及长期影响。方法:对行腺样体切除术的患儿分别于术前、术后1周、1个月及3个月进行患儿父母或陪护人员调查问卷、吹泡试验及计算机语音声学分析。结果:①患儿父母或陪护人员调查问卷显示,31例中有22例术后有鼻音增高的改变,有9例术后3个月此症状仍存在。有7例术后出现鼻腔食物反流,且均同时有鼻音增高,但鼻腔食物反流全部于术后1个月内消失。②吹泡试验反映术后1周内患儿存在腭咽闭合功能不全(P<0.01),术后1、3个月差异均无统计学意义(均P<0.05)。③计算机语音声学分析结果显示,患者术后短期内出现辅音残缺、元音共振峰残缺和鼻化音的异常语图表现,术后3个月时基本恢复正常;术后/i:/音F3峰值与术前相比降低,尤其是术后1周时F3峰值降低最明显(P<0.01)。结论:儿童腺样体切除术后大部分儿童可出现一过性腭咽闭合功能不全的表现,但未见其对腭咽闭合功能有长期的影响。Objective：To study the early and long term effect on velopharyngeal closure function by children adenoidectomy. Method：An investigation on parents or person who attended the children to be executed adenoidectomy, blowing soak test and computerized phonography were carried on 1 week, 1 month, and 3 monthes preoperatively and postoperatively, respectively. Result：①The investigation showed that 22 in 31cases presented hypernasality, in which 9 lasted more than 3 months after operation, Seven children presented nasal regurgitation of food and hypernasality only within 1 month. ②Blowing soak test showed velopharyngeal insufficiency within 1 week（ P 〈0.01）after operation. ③Some voice figures appeared consonant and formants incomplete, and nasalization in the early period after operation. The value of F3 in /i：/ decreased after operation, especially within 1 week. Conclusion：Velopharyngeal insufficiency appears on most children after adenoidectomy transiently. There is no evidence shows a long term influence on velopharyngeal function for children after adenoidectomy.
