- Abstract:
- Objective To investigate the efficacy, safety, and postoperative recovery of plasma radiofrequency ablation at varying dose parameters in pediatric adenoid hypertrophy, while analyzing the dose-effect relationship and determining the optimal parameter range, thus providing a scientific basis for clinical practice. Methods A retrospective analysis was conducted on 55 children diagnosed with adenoid hypertrophy. According to plasma radiofrequency ablation energy, patients were categorized into low-dose group (100 W, n=20), medium-dose group (200 W, n=20), and high-dose group (300 W, n=15). These groups were compared for adenoid-nasopharyngeal ratio improvement at 1-month follow-up, intraoperative blood loss, postoperative pain score, complication rate, and postoperative recovery time. Results Postoperative adenoid-nasopharyngeal ratio improvement was significantly greater in both medium- and high-dose groups as compared with low-dose group (P<0.05), while no significant difference was observed between medium- and high-dose groups (P>0.05). The high-dose group had intraoperative blood loss of (26.4±4.8) mL and higher postoperative wound bleeding incidence than low- and medium-dose groups (P<0.05). The postoperative pain scores on postoperative days 1 and 3 were higher in high-dose group than in the other two groups (P<0.05). These results suggested that medium-dose group achieved the optimal balance between efficacy, safety, and postoperative recovery. Conclusion Plasma radiofrequency ablation with a medium-dose setting of 200 W provides optimal adenoid removal while reducing intraoperative bleeding, minimizing postoperative complications, and shortening recovery time.
