随着发音手术技术如应用肉态杆菌毒素治疗痉挛性发直困难及喉返神经损伤的手术治疗等的发展，检查评定喉肌活动能力的技术也提到相应重要的地位。喉肌电图已常用于临床以检测喉肌的神经支配和连带运动。近年来推广的磁刺激法是一种无损伤刺激周围神经的方法，也已应用于检查喉 With the development of sounding techniques such as the treatment of spasmodic dysplasia and the surgical treatment of recurrent laryngeal nerve injury with the use of the bacillus toxin, the technique of examining the ability to assess the activity of the laryngeal muscles has also been mentioned as being of considerable importance. Laryngeal EMG has been commonly used clinically to detect the innervation of the laryngeal muscles and associated movement. In recent years, the promotion of magnetic stimulation is a non-invasive stimulation of peripheral nerve method, has also been used to check the throat
