先天性腭裂术后腭咽闭合功能的动态观察

A STUDY OF VELOPHARYNGEAL CLOSURE IN PATIENTS WITH OPERATED CLEFT PALATE

根据咽腔造影后,咽腔侧位、颅底正位X线片的测量以及电视透视及电视录像观察,67例腭裂术后患者吞咽时均能达到完全的腭咽闭合,而用力吹气和发音时大部分不能形成完全的腭咽闭合,用力吹气时腭咽闭合较发音时容易,发辅音时腭咽闭合较发元音时容易。腭咽闭合的部位在腭板以下、第一颈椎以上的水平上。腭咽部活动时咽后壁动度不大。

The authors studied 67 operated cleft palate patients with television fluoroscopy and X-ray photograph by the base and leteral view after nasopharynx was coated with barium,Velopharyngeal closure was observed during swallowing,blowing and producing Chinese vowels and consonants.Sixty-seven operated cleft palate patients had complete closure during swallowing,but most of them had incomplete closure during blow- ing and phonation.The authors considered that complete closure when producing vowels was the most difficult to obtain and closure when pro- ducing consonants was more difficult then that during blowing.The height of velopharyngeal closure was between the atlas tubercle and the palate plane.This study showed insignificant posterior pharyngeal wall movement during blowing,vowles and consonant phonation.
