Minimally invasive tonsillectomy improves operative efficiency over cold dissection in chronic tonsillitis

This systematic review and meta-analysis of 16 randomized controlled trials including 1528 patients undergoing tonsillectomy for chronic tonsillitis compared minimally invasive tonsillar surgical techniques with cold dissection tonsillectomy. The primary outcome was not reported in the available abstract; however, the analysis provided results for operative efficiency. Minimally invasive surgery tended to improve operative efficiency, with a pooled mean difference of -10.48 minutes (95% CI -13.54 to -7.42), favoring the minimally invasive approach. The confidence interval did not cross zero, suggesting statistical significance (exact P value not reported).

The review did not report on secondary outcomes, adverse events, or follow-up duration. Limitations of the analysis were not described in the available abstract, and the certainty of evidence was not assessed. The absence of a clearly defined primary outcome and lack of safety data limit the clinical applicability of these findings.

Clinicians should interpret these results cautiously. While minimally invasive techniques may offer shorter operative times, the review does not provide evidence on postoperative pain, bleeding, recurrence, or other patient-important outcomes. Further research with well-defined endpoints and comprehensive safety reporting is needed before changing practice.
