[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.
Conclusion:
RVPI can be used as a parameter of quantitative analysis for velopharyngeal function, and our results suggested that it is reliable and reproduciable.
