Abstract: Patients with oral cancer may experience some degree of dysphagia, either as a direct result of the cancer itself or as a result of treatment. Dysphagia is easy to cause a series of complications, which seriously affect the rehabilitation process and quality of life of patients. Therefore, it is very important to find out whether patients have dysphagia timely and accurately. Currently, research on dysphagia in patients with oral cancer is still in the initial stage in China, and there is no uniform standard for screening of dysphagia. This paper summarizes the different characteristics and application status of screening tools for dysphagia in patients with oral cancer, and analyzes their advantages and disadvantages, in order to provide references for clinical workers to choose appropriate screening tools.

Key words: oral cancer; dysphagia; screening tools
