对７０５例声带息肉、声带小结等声带良性病变，进行了喉显微手术，术后对其中２０４例患者，根据不同病因，酌情进行了发声矫治，并在手术前后应用了元音量化好、幅值精度高的ＨＪＹ－Ｉ型智能化喉疾仪，进行了嗓音声学动力分析，经１～３个月随访治愈好转率达９７．５％。从喉空气动力学提出了喉显微手术后，进行发声矫治病理生理学的理论依据及其矫治方法：并对ＨＪＹ－Ｉ型智能化喉疾仪的功能及特点作了概述。 705 cases of vocal cord polyps, vocal nodules and other benign lesions of the vocal cord, laryngeal microsurgery surgery, of which 204 patients after surgery, according to different causes, as appropriate, vocalization correction, and before and after the application of vowel quantification, amplitude Value of high precision HJY-I intelligent laryngoscope, voice acoustic dynamic analysis, after 1 to 3 months follow-up cure rate improved 97.5%. After laryngeal microsurgery was proposed from laryngeal aerodynamics, the theoretical basis and corrective methods of vocalization and pathophysiology were summarized. The functions and features of HJY-I intelligent laryngograph were summarized.
