To evaluate the effect of a system of velopharyngeal incompetence (VPI) management after the application of obturator.
Using nasopharyngofiberoscope (NPF) and a computer analysis system, we quantitatively analyzed the improved state of velopharyngeal incompetence in 100 patients with unilateral and/or bilateral cleft palate.
The velopharyngeal closure (VPC) can be greatly improved by using a temporary oral prosthesis (obturator) and speech training. An objective quantitative standard was established to evaluate the change of velopharyngeal closure of cleft palate patients after surgery and conservative treatment.
The method used is more succinct, accurate and practical than previous methods. In order to reflect the state of velopharyngeal incompetence, the concept of improvement rate of velopharyngeal incompetence (IRVPI) is put forward.
评估腭咽闭合不全（VPI）管理系统在应用阻塞器后的效果。
使用鼻咽喉纤维镜（NPF）和计算机分析系统，我们对100例单侧和/或双侧腭裂患者腭咽闭合不全的改善状态进行了定量分析。
使用临时口腔修复体（阻塞器）和语音训练可大大改善腭咽闭合（VPC）。建立了一个客观的定量标准来评估腭裂患者术后及保守治疗后腭咽闭合的变化。
所采用的方法比以往方法更简洁、准确和实用。为反映腭咽闭合不全的状态，提出了腭咽闭合不全改善率（IRVPI）的概念。
