Tonsillae (lat. Tonsillae) are accumulations of lymph tissue located at the intersection of the digestive and respiratory systems. The palatine tonsils and the third tonsil are part of the Waldeyer ring that prevents microorganisms from coming into our body through air or food. The size of the tonsils depends on age and heredity. The palatine tonsils are most developed in puberty, the third tonsil in early childhood, the lingual tonsils in adulthood. If the tonsils do more harm than good to the body, they should be removed. The main reasons for surgery in children are enlarged tonsils in combination with an enlarged third tonsil, in a person suffering from purulent angina five or more times within two years and in suspected tumor. In addition to the most common classic tonsillectomies, there are many other methods of tonsillectomy, such as laser tonsillectomies, tissue excision with an electrocoagulator and an ultrasound scalpel, and radiofrequency ablation. The aim of this paper is to explain the importance of tonsils in the body, the benefits and harms of their removal and the complications that may occur. Before surgery, it is necessary to make a health care plan that contains the diagnosis, goals and interventions. An important role in the patient's health care is played by the nurse who develops the health care plan, implements it and finally evaluates the performed procedures. Establishes a therapeutic relationship with the patient and mentally and physically prepares him for surgery. After surgery, it educates the patient about the behavior and proper diet that must be followed. A quality relationship between the nurse and the patient achieves better cooperation and prevents unwanted mistakes in health care.
