[Clinical analysis of adenoid surgery in infancy].

To investigate the effects of postoperative surgical treatment of infantile adenoidal hypertrophy on children, the recurrence rate, and the changes in immune levels before and after surgery. Low temperature plasma ablation was performed in 11 infants with adenoidal hypertrophy to evaluate the risk of postoperative anesthesia and the effect of surgery on recurrence rate and immunity. During the follow-up period of 3 to 6 months, 2 patients had recurrence（18.18%）, including 1 case with round pillow hyperplasia and 1 case with tonsil reactive hyperplasia. Three months after surgery, the immune level did not decrease significantly compared with that before surgery. No serious complications occurred in all children. Infants with adenoidal hypertrophy fall asleep, snoring, open mouth breathing, and belching seriously affect the quality of sleep and growth. Children who have been ineffective for more than 2 months undergo low-temperature plasma ablation. General anesthesia is safer. After that, the sleep quality of the children was significantly improved, and the immunity did not decrease significantly. Low temperature plasma ablation in infants with adenoidal hypertrophy is safe and effective, but it is not a routine treatment. Clinical symptoms are easy to repeat. The indications for surgery should be appropriately weighed.
