A Study of Nasalance for Normal Korean Children using Nasometer Ⅱ

Assessment of speech nasality provides important information for the treatment of velopharyngeal incompetence. The perceptual judgement of nasality is still used in assessment of velopharyngeal incompetence, but it should not be the sole criterion for speech nasality. Objective procedures may be used to assess velopharyngeal function, in examples nasometer, aerodynamics, x-ray, electromyography, nasoendoscopy and videofluoroscopy etc. The aim of this study was to obtain comprehensive nasalance data for the Korean children, aged 7 years and to investigate any tonsil differances within that age group. The results were as follow : The nasalance of the children in respect of the tonsil was higher in grade III than grade I in vowels (/i/, /u/, /wi/ ) , plosives ( /p /, /t /, /k / ), affricatives ( /c / ) and fricatives (/s/, /∫/).
