腭咽环扎术后腭咽闭合功能的远期疗效评价

随机对腭咽环扎术后１６年的部分患者进行了全面检查，包括语音评价，咽腔造影，并使用电子动态喉镜检查腭咽闭合功能。结果１６例患者的语音检查优良率为９３％。研究表明：腭咽环扎术后的腭裂患者其环扎线的向心性牵拉力量使鼻咽腔能从前后左右４个方向将鼻咽腔全面缩小，为语音功能的恢复创造有利条件。同时，咽腔大小随患者年龄增长而改变，不会限制其生长发育。

An Evaluation of the Long term Results of Palatopharyngeal Closure Function After Velopharyngeal Ring Ligation

cases were selected randomly from a group of 36 postoperative patients who underwent velopharyngeal ring ligation 16 years ago for evaluation of pronunciation, pharyngeal radiography, and electric endostroboskop to evaluate the patients' velopharygeal closure function. It was found that the pronunciation function of 93% patients were in good status. The results showed that centripetal force of velopharyngeal ring ligation made the velopharyngeal cavity reduced from the right to left and from anterior to posterior sides. It was good for sphincter of velopharyngeal moving, which could reduce the space of pharyngeal cavity and add the length of soft palate. The velopharyngeal closure was improved, which produced a good condition for the recovery of pronunciation function, at the same time, the change of pharyngeal cavity adapts to the patient's growth without limiting the growth and development of nasovelopharyngeal.
