Abstract / Bemerkung
OBJECTIVE: To systematically review the literature on harmonic scalpel tonsillectomy with a view of comparing its postoperative hemorrhagic rate with the conventional methods for tonsillectomy.

DATA SOURCES: Cochrane Library, Medline, Embase, CINAHL, INAHTA, CRD (Centre for Review and Dissemination, York, UK), and related databases. The date of the last search was September 19, 2006; papers were considered irrespective of language of publication.

REVIEW METHODS: Inclusion and exclusion criteria were applied independently by two reviewers with a third reviewer available for adjudication. The papers were quality assessed using Chalmers' criteria. Eleven randomized controlled trials (RCT) were included in the final review with five RCTs comparing harmonic scalpel tonsillectomy with “cold steel” tonsillectomy and six RCTs comparing harmonic scalpel with “hot” tonsillectomy techniques.

RESULTS: All studies were underpowered to detect a significant difference in the postoperative hemorrhagic complication between harmonic scalpel and the comparator tonsillectomy techniques. The heterogeneity of studies made quantitative combination of results impossible.

CONCLUSION: The evidence reviewed is of low quality and does not support any significant difference in postoperative hemorrhage rates when harmonic scalpel is compared with other tonsillectomy techniques. As studies have numerous methodological flaws and incorporate biases and confounding factors, these results need to be interpreted with caution. Larger and better-conducted studies would be needed in order to compare the safety of harmonic against conventional tonsillectomy methods. The need for a large sample size might make an RCT impractical; therefore a large, well-controlled cohort study could be more suitable.
