[The normal people's parameters of the velopharyngeal incompetence(VPI) by cephalometric analysis]
OBJECTIVE:To estimate velopharyngeal incompetence(VPI)in patients with cleft lip and palate,we seek for the normal people's parameters of VPI. METHODS:Studying on 222 normal people with VPI by cephalometric analysis,the parameters of the normal people have been set up.RESULTS: There was remarkable correlationship between the rate of velopharyngeal sagital restriction by cephalometric analysis and the rate of VPI by nasopharyngeal endoscope.CONCLUSION:Cephalometric analysis is useful to estimate the function of velopharyngeal closure and mobility of the soft palate.
