With the advancement of surgical techniques and equipment, as well as the further understanding of laryngeal embryogenesis and anatomy, partial laryngectomy is increasingly used in clinical practice. According to the bulk of international and domestic literature, there is no significant difference in survival between partial laryngectomy and total laryngectomy as long as the indication and case selection are correct, and partial laryngectomy can preserve the maximum laryngeal function, thus improving the quality of survival of patients. For partial laryngectomy, there are many procedures, such as laryngectomy, vertical partial laryngectomy, horizontal partial laryngectomy, 3/4 laryngectomy, crico-lingual-epiglottic fixation (CHEP), etc. The choice of the procedure is mainly based on the site of the tumor and the extent of invasion, so it is necessary to conduct the corresponding examination and full evaluation before the operation in order to choose the appropriate surgical method and achieve the best treatment results. Therefore, preoperative examination must be performed and adequate evaluation must be made before selecting the appropriate surgical procedure to achieve the best treatment result. Although partial laryngectomy is more and more widely used, it still cannot replace total laryngectomy. For some advanced lesions, the tumor breaks out to the outside of the larynx and invades the surrounding organs and tissues, it is undesirable to use partial laryngectomy to emphasize the quality of life and cause residual tumor.
