作者研究先天性腭裂小儿手术后用电流刺激腭肌辅助语音矫治的效果,观察50例,男22例,女28例,年龄5岁～7岁。分两组,第1组18例,完全性腭裂。第2组32例,完全性腭裂合并牙槽突裂。手术前即开始语音训练,学习正确的发音和呼吸。预先检查健康小儿(15例)舌腭肌、腭帆张肌、腭帆提肌、升上唇肌、鼻翼肌、降下唇肌、口轮匝肌、颏肌和面神经下颌缘支电兴奋阈正常值:对平流电流的反应为0.2～0.4mA,对指数曲线型电流为0.8～1.2mA,对直角电流为0.8～0.6mA。腭裂小儿,腭肌收缩弛缓,
The author studied the effect of electric stimulation of palatal muscle assisted by electric current after pediatric cleft palate surgery, observed 50 cases, 22 males and 28 females, aged 5 to 7 years old. Divided into two groups, the first group of 18 cases, complete cleft palate. Group 2 32 cases, complete cleft palate with alveolar cleft. Start voice training before surgery to learn the correct pronunciation and breathing. Pre-check the healthy children (15 cases) of the palate, palatine saphenous muscle, palatal saphenous muscle, ascending lip muscle, alar wing muscle, lower lip muscle, orbicularis muscle, : The response to the advection current is 0.2 to 0.4 mA, the exponential curvilinear current is 0.8 to 1.2 mA, and the right-angle current is 0.8 to 0.6 mA. Cleft palate, palatine muscle relaxation,
