Abstract: Objective To analyze the long-term efficacy and factors influencing clinical outcomes of adenoidectomy and tonsillectomy using ablation in pediatric patients with grade 1 tonsils and obstructive sleep apnea hypopnea syndrome(OSAHS). Methods Clinical data of 119 children with grade 1 tonsils and obstructive sleep apnea hypopnea syndrome(OSAHS)were collected. Children were treated using different surgeries between January and December 2012, and the surgical outcomes were retrospectively analyzed. Patients in the experimental group(60 cases)were treated with adenoidectomy and tonsillectomy with ablation; patients in the control group(59 cases)were treated with adenoidectomy ablation. Postoperative efficacy and quality of life of the two groups were compared after 6 months and 1, 2, and 4 years. Results Four years after surgery, in the experimental group, 53 patients were cured, 4 showed improvement, and 3 had experienced no effect; the total effective rate was 95%. In the control group, 25 patients were cured, 24 showed improvement, and 10 were invalid; the total effective rate was 83.05%. The effective rate of the experimental treatment was statistically superior to the effective rate of the control treatment(P<0.1). The factors influencing clinical outcomes included age, obesity, rhinitis and nasosinusitis, otitis media, and dento-maxillofacial deformities. The long-term complications included two cases of pharyngeal foreign body in the experimental group. Conclusion Adenoidectomy and tonsillectomy with ablation is an effective method for treatment of children with OSAHS with grade 1 tonsils.
