Abstract:ObjectiveTo evaluate the efficiency, effect and safety of coblation tonsillectomy compared with monopolar electrocautery tonsillectomy through metaanalysis.MethodsRandomized controlled trials (RCT) comparing coblation with monopolar electrocautery tonsillectomy or adenotonsillectomy were searched from Pubmed, Embase, Cochrane Library and Chinese databases. Outcome indexes included postoperative hemorrhage, postoperative pain, operative time, intraoperative blood loss and recovery condition. RevMan 5.2 software was used for statistical analysis.Results10 RCTs (n=716) met the eligibility criteria. Metaanalysis illustrated that the two groups were similar in terms of postoperative hemorrhage ［OR=1.02,95%CI(0.51,2.03)］. No significant differences were found in operative time ［SMD=0.60,95%CI(-0.08,1.28)］, intraoperative blood loss ［SMD=0.34,95%CI(-0.02,0.69)］ and postoperative pain ［SMD=-0.55,95%CI(-1.19,0.08 )］. Coblation was associated with quick diet recovery, yet activity recovery was similar in two groups.ConclusionsPatients with coblation tonsillectomy seem to have quicker diet recovery than those with monopolar electrocautery. Compared with monopolar electrocautery tonsillectomy, coblation does not appear to decrease the postoperative hemorrhage rate, intraoperative blood loss and postoperative pain.
