title: [The influence on velopharyngeal function by children adenoidectomy].
abstract: OBJECTIVE
  To study the early and long term effect on velopharyngeal closure function by children adenoidectomy.
  
  
  METHODS
  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 months preoperatively and postoperatively, respectively.
  
  
  RESULTS
  1) The investigation showed that 22 in 31 cases 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. 2) Blowing soak test showed velopharyngeal insufficiency within 1 week (P <0.01) after operation. 3) Some 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.
