Abstract
Objective
To evaluate whether plasma ablation tonsillectomy is superior to other hot techniques in reducing postoperative morbidity.
Data Sources
The databases of PubMed, EMBASE, and Web of Science were used to search the literature, from inception to January 2, 2020. Randomized controlled trials (RCTs) that compared plasma ablation tonsillectomy with any other hot techniques were eligible.
Review Methods
A modified Cochrane tool was used to assess the risk of bias. The standardized mean difference (SMD) and 95% confidence interval (CI) were used to estimate pooled effects of postoperative pain, and the risk ratio (RR) was used for postoperative bleeding. Subgroup analysis was prespecified to explore the source of heterogeneity. The evidence quality of each outcome was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
Results
A total of 15 RCTs were included (n = 1293). Comparing with other hot techniques, plasma ablation tonsillectomy may cause less pain on postoperative day 7 (SMD, −0.53; 95% CI, −0.84 to −0.23). However, the magnitude of the difference may be clinically meaningless. There were no significant differences not only in terms of postoperative pain on day 1 and day 3 but also in the incidence of postoperative bleeding, reoperation hemostasis, and return to normal diet and activities between the 2 groups.
Conclusion
There is still substantial uncertainty on postoperative pain, bleeding, and recovery. The current evidence is insufficient to demonstrate that plasma ablation is superior to other hot techniques for tonsillectomy.
