First, surgery is now generally done by minimally invasive surgery in outpatient clinics. The operation is painless and the wound is relatively small. I suggest you check the cause of chronic sinusitis in your child first, and then treat it symptomatically.
Second, if your child suffers from this disease for a short time, then his treatment time and cost will be very low. If he has suffered from this disease for a long time and his condition is serious, then the time and cost of treatment will be more.
Third, medication can only temporarily relieve your child's symptoms, but can't completely treat your disease. Long-term medication can also cause drug-induced rhinitis.
Fourth, anti-inflammatory measures should be taken after operation, but it is recommended that you do it in spring and summer, and the effect will be quite good.
