First of all, it is important to tell parents that children over 3 or 4 years old have a well-developed lymphatic ring in the pharynx, and after adenoids and tonsils surgery, other lymphatic tissues can compensate for their work and perform immune functions. We have done a long-term follow-up of a large sample of children after adenoids and tonsils surgery, and there is no difference in cellular and humoral immunity between children with adenoids and tonsils surgery and normal children. However, caution should be exercised in children under 3 years of age, and it is generally not recommended to remove all of the tonsils. A portion can be retained. Secondly, if your child’s tonsils are often septic and have high fever, more than 4-5 times a year, then during adenoid surgery the doctor recommends removing all of the tonsils, first to avoid frequent, repeated inflammation affecting the heart and kidneys in the future, and secondly, repeated inflammation of the tonsils is prone to hyperplasia after surgery. If your child’s tonsils are basically not septic, inflamed, or occasionally 1-2 times, then there are different ways to deal with them depending on the size of the tonsils. This is because the low temperature plasma radiofrequency ablation technology now allows us to update and improve our procedures in ways that were simply not possible before. For 3rd degree hypertrophic tonsils, all of them can be ablated or most of them can be ablated, but it is not recommended to leave them untreated. This is because every year we have children who have to have a second surgery because they did not have their tonsils treated during the last surgery and now have abnormally enlarged and hypertrophied tonsils. There are also different treatments for 2nd degree hypertrophy of the tonsils depending on the size. The treatment of large 2nd degree, near 3rd degree hypertrophy tonsils is the same as that of 3rd degree hypertrophy tonsils. Tonsils with small 2nd degree hypertrophy can be partially ablated or decompression surgery can be performed. The results of volume reduction are particularly good for small 2-degree hypertrophy tonsils, and basically no re-growth of hypertrophy of tonsil tissues was found in the 1-year follow-up after the surgery. However, for large 2nd and 3rd degree tonsils, the results are not particularly good because there is a certain limit to the volume reduction. In the past, the tonsils of degree 1 were not treated. Now, with the increasing number of children operated on and the increasing number of follow-up visits, we have found that the tonsils that were 1 degree at the time of surgery have become enlarged and hypertrophied to varying degrees after surgery, and some have begun to affect the child’s breathing and sleep. Therefore, at present, we generally recommend to perform volume reduction on the 1st degree size tonsils as well, which can make the tonsil tissues appear scar tissue hyperplasia to avoid abnormal hyperplasia and enlargement in the future (especially for the younger children).
