[A comparative study of velopharyngeal function after palatoplasty with different age group].

That the most suitable age of palatoplasty is still an argumentative question.The final purpose of palatoplasty is to obtain the satisfactory effectiveness is to obtain the satisfactory effectiveness of phonetic distinctness.So,early palatoplasty is suported by more more experts and patient's parents.This study detected 60 cases velopharyngeal function after traditional palatoplasty with two flaps,adopting nasopharyngeal fiberscope and detective system of image processing and quantitative analysis of velopharyngeal function,for long term evaluation of traditional palatoplasty with different operative success iin early palatoplasty group (less than 3 years old) was 80.0% while that in later palatoplasty group (more than 6 years old) was 53.3%.From other aspects of types of velopharyngeal competence,mobility of soft palate and rate of velopharyngeal coronary contraction,the author described advantages of early palatoplasty.
