Abstract:Head and neck lymphedema (HNL) is usually secondary to treatment of head and neck tumor, its symptoms and signs are not typical. Though the degree of swelling is lighter than that of secondary lymphedema after treatment of breast cancer and cervical cancer, due to the particularity of the anatomical position of the head and neck, it has a serious long-term impact on the appearance, sensation, movement and even psychology of patients. At present, clinicians pay little attention to head and neck lymphedema, lack of adequate understanding, diagnosis and treatment methods and procedures are not standardized, and lack of complete diagnosis and treatment guidelines to guide medical work, which still needs to be further explored. This article reviews the progress of diagnosis and treatment of head and neck lymphedema at home and abroad in recent years, in order to further clarify the diagnosis and treatment of head and neck lymphedema.
