Laryngeal carcinoma is a common malignant tumor in the head and neck,and the squamous cell carcinoma of the larynx is the most prevelance.In view of the importance of laryngeal function and its survival,thechoice of the best therapeutic regimen of laryngeal carcinoma must consider the potential survival rate and the change of postoperative function.The margin of laryngeal carcinoma is an important index of preoperative imaging evaluation of laryngeal carcinoma.The accurate determination of the cutting edge determines the operation mode,the success rate,the survival rate and prognosis of the patients with laryngeal carcinoma.In recent years,the method of preoperative evaluation of laryngeal tumors is diverse,including molecular,imaging and endoscopy,among which preoperative imaging is the most common method.The purpose of this study was to summarize the evaluation of different imaging techniques in the assessment of local invasion and recurrence of submucosal tumors in laryngeal carcinoma.
