In recent years, the incidence of obstructive sleep apnea syndrome (OSAS) in children has been increasing year by year and is causing concern among parents. This disease is caused by enlarged tonsils and adenoids in most children, and once the diagnosis is clear, the adenoids and tonsils must be removed. When it comes to surgery, parents are often very worried and afraid. Here are a few of the different surgical approaches to adenoids and tonsils. The initial surgeries are performed without anesthesia, and in just a few minutes the doctor uses experience to remove the tonsils with a circle-shaped knife called a tonsil squeeze cutter and scrape the adenoids with an adenoid cutter. Because the child cannot cooperate well, it is easy for the tissue to remain during the surgery and to grow and hypertrophy again. Moreover, children are very afraid and it will leave a shadow on their psychology. Later, with the development of pediatric anesthesia technology, the operation of tonsils and adenoids was changed to be performed under general anesthesia, and a blender-like power system was used to churn and aspirate the adenoids, while the tonsils were still peeled off and removed. However, the disadvantage is that there is more bleeding, some small parts of the adenoid tissue are easily overlooked when bleeding and remain, and the postoperative hemostasis is done with electrocoagulation, which is more damaging to the surrounding tissues. Recently, the real minimally invasive surgery is the low temperature plasma radiofrequency ablation, which uses plasma light waves to vaporize and eliminate adenoids and tonsil tissues, with almost no bleeding on the trauma surface, and is low temperature, which is less painful to the surrounding tissues and faster recovery for the child after the surgery. Usually on the day the child receives the tonsils and adenoids, we give them cold fluids, just like milk, juice, yogurt, ice cream, etc. The next day they can eat warm semi-liquid foods, such as noodles, porridge, cakes, ravioli, etc. After 7-10 days, when the white membranous material on the surface of the surgical wound has receded, they can eat ordinary meals. Some children may have fever for 3-5 days after surgery, which usually occurs after surgical procedures and is called “surgical fever”. If the bleeding is small, it will stop on its own; if it is large and persistent, you should go to the hospital for emergency treatment. Snoring and open-mouth breathing will not disappear immediately after surgery, and will often be aggravated within a few days because of the edema of the wound, parents should not worry, it will usually slowly improve and disappear a week after surgery. With advances in anesthesia and surgical techniques, tonsil and adenoid surgery has now become a safe, quick and routine procedure. Parents should not be overly concerned or afraid.
