title: [A preliminary study on speech therapy for marginal velopharyngeal insufficiency].
abstract: OBJECTIVE
  To investigate the feature and therapy of patients with marginal velopharyngeal insufficiency(MVPI).
  
  
  METHODS
  Fifteen patients(10 males,5 females, age ranging form 8 to 25 years, mean age of 17.6 years) with MVPI were selected. All the patients received behavior therapy and speech therapy. Chinese speech intelligibility test and blow test were carried out before and after the therapy.
  
  
  RESULTS
  All cases achieved satisfactory results through 12 to 20 weeks of speech therapy. The results of speech intelligibility test and blow test after therapy were better than those before therapy.
  
  
  CONCLUSIONS
  For patients with MVPI, a satisfactory result and pronunciation improvement could be obtained through a series of behavior therapy and a good velopharyngeal closure.
