Introduction and objective: Adenotonsillectomy for treatment of childhood obstructive sleep apnoea is effective. The uncomfortable postoperative period and possible complications have significantly increased the use of partial techniques, seeking to improve these aspects while achieving the same results in resolving sleep apnoea. The aim was to present the experience with 2 consecutive groups of patients, comparing total tonsillectomy to bipolar radiofrequency ablation (RFA).

Method: A group of 96 children that underwent total tonsilloadenoidectomy using cold dissection were compared to another group of 101 children that underwent RFA. In all cases, polysomnography was performed before and 1 year after surgery. The percentage of cases with persistent disease (apnea-hypopnea index ≥ 3) and the improvement of clinical symptoms at one year were evaluated. The percentages of surgical and anaesthetic complications in both groups were also compared.

Result: The persistence of the syndrome was comparable in both groups: 25% in the cold dissection and 22.77% in the radiofrequency ablation group. Anaesthetic complications (5% in the group where cold dissection was used and 4.2% in the radiofrequency ablation group) and postoperative bleeding rates were very low and statistically comparable with both techniques.
CONCLUSION: In the treatment of childhood obstructive sleep apnoea syndrome, both extracapsular surgery using cold scalpel and bipolar radiofrequency tunnelling techniques are safe. Likewise, results as to resolution of the syndrome show no statistically significant differences.
