[A contemporary review of the surgical margins in laryngeal carcinoma].

Summary Laryngeal squamous cell carcinoma is a common malignant tumor of the head and neck. Although the treatment methods and concepts have changed, surgery is still an important treatment for laryngeal cancer. Most studies have shown that the state of the margin of laryngeal surgery is closely related to the patient's recovery. However, in clinical practice, different doctors often have inconsistent grasping of the margin distance in laryngeal cancer surgery. On the one hand, it may be because the surgeon is on the throat. The characteristics of the margin of cancer are not well understood. On the other hand, the confusion of the concept of the margin and the complexity of the margin of laryngeal cancer may be more important reasons. For example, different terms related to margins are used in English literatures. Therefore, this article reviews the concept, acquisition, evaluation and cuttingedge research of laryngeal surgical margins to improve the standardization of clinical laryngeal surgical margin assessment and promote the in-depth development of related research.
