一侧声带麻痹常因声门闭合不紧而嘶哑,临床上常有声门已经能够充分闭合而发音仍感粗糙者。作者为了探索除了声门闭合以外恢复发音的因素,采用患侧声带硅注射疗法。将喉闪光器的光束用二条玻璃纤维导至喉镜,再通过手术显微镜观察声带的动态,拍成照片,对注射前后声带振动的形态进行分析。 One side of the vocal cord paralysis often due to closed tightness and hoarseness of the glottis, clinically often glottis has been able to fully closed and the pronunciation is still a sense of roughness. In order to explore the factors that restore pronunciation other than glottis closure, the authors used ipsilateral vocal cord silicon injection therapy. The throat flasher with two glass fibers led to the laryngoscope, and then observed the dynamics of the vocal cords through a surgical microscope, photographs, vocal cord vibration before and after injection morphology analysis.
