title: [Quantitative analysis of velopharyngeal function by nasopharyngeal fibroscope (NPF)].
abstract: OBJECTIVE
  To estimate the reliability of the nasopharyngeal fibroscope (NPF) for assessing velopharyngeal function.
  
  
  METHODS
  16 well-pronounced males were examined by NPF which was positioned in different depth. Same procedures were repeated after a week.
  
  
  RESULTS
  The results indicated that the rate of velopharyngeal incomptence (RVPI) of NPF had no significant difference when checked in different time and various depths.
  
  
  CONCLUSIONS
  RVPI can be used as a parameter of quantitative analysis for velopharyngeal function, and our results suggested that it is reliable and reproduciable.
