〔Abstract〕 Objective To investigate the effect of nasal endoscopy combined with low-temperature plasma radiofrequency ablation adenoidectomy on sleep quality in children with snoring. Methods A total of 114 children with snoring were selected from Anyang District Hospital from November 2021 to November 2022 and divided into a control group and an observation group by computer random table method, with 57 cases in each group. The control group underwent nasal dynamic cutting adenoidectomy, and the observation group underwent nasal endoscopy combined with low-temperature plasma radiofrequency ablation adenoidectomy. The sleep quality and surgical indexes of the two groups were compared. Results The operation time, intraoperative blood loss and hospital stay in the observation group were shorter than those in the control group, and the differences were statistically significant (P < 0.05). The total effective rate of the observation group was higher than that of the control group, the difference was statistically significant (P < 0.05). The sleep quality of the observation group was better than that of the control group after treatment, and the difference was statistically significant (P < 0.05). The total incidence of complications in the observation group was lower than that in the control group, and the difference was statistically significant (P < 0.05). After treatment, the scores of quality of life in the observation group were higher than those in the control group, and the differences were statistically significant (P < 0.05). Conclusion Nasal endoscopy combined with low-temperature plasma radiofrequency ablation adenoidectomy is performed on children with snoring to improve surgical indicators, enhance the therapeutic effect, improve sleep quality in children, reduce complications and improve quality of life.
