Obstructive sleep apnea syndrome is simply snoring. As my years of medical practice grow, my understanding of this disease has gone through several stages, and I would like to talk about my views, hoping that it will be helpful to parents. At that time, I thought it was necessary to put my child under general anesthesia and risk surgery for a very common symptom called “snoring”. Or should we wait until the condition is very serious and then operate, or not do it if the condition is not serious? As my experience grows, and after I operated on children myself, I have come into contact with a lot of children who have been re-examined after surgery. Many parents commented on the surgery: If I had known the results were so good, I would have operated long ago! Many children have changed drastically within half a month after surgery: they don’t snore anymore, they eat better, and they grow bigger. With the maturity of the technology and the reading of foreign literature, the understanding of this problem has become more and more profound, and this problem still has a great impact on children, and surgery should still be the preferred treatment. At the time of writing this article, I found that treatment with nasal spray hormones and leukotriene receptor antagonists was also effective abroad, but it was still in the exploratory stage, and there was no definite conclusion on how long to use the treatment course and how much effect could be received. In my subsequent work, I tried conservative treatment with these drugs for some children whose parents were more afraid of surgery, and most of them received good results. In the end, I think it is more acceptable to try conservative treatment for children with mild cases, while surgery is still recommended for children with moderate to severe cases. About half of the children with mild cases can avoid subsequent surgery after conservative treatment (the other half with mild cases still need surgery). The usual course of conservative treatment is about 3 months. Whether the treatment is conservative or surgical, I think it is necessary to have polysomnography if possible.
