LigaSure versus Conventional Parotidectomy: A Systematic Review and Meta-Analysis

Abstract

Surgery with parotidectomy is the preferable treatment for most parotid tumors. Our meta-analysis compared the differences between the use of the LigaSure (LS) device and the conventional suture ligation technique (CT) in parotidectomies. A literature search in databases including EMBASE, MEDLINE, and the Cochrane Library was carried out. Studies including parotidectomy using LS and CT were included with the intraoperative and postoperative parameters collected. Continuous operative time data were measured by mean differences (MDs). Discrete data on postoperative complications, including facial palsy, postoperative bleeding, and salivary complications, were evaluated with risk differences (RDs). All values were reported with 95% confidence intervals (CIs). Five studies were included in our meta-analysis. The pooled analysis demonstrated a significant reduction in operative time in the LS group (MD: −21.92; 95% CI, −30.18 to −13.66). In addition, the analysis indicated that the incidence of postoperative complications, including permanent facial palsy (RD, −0.01; 95% CI, −0.06 to 0.05), temporary facial palsy (RD, 0.00; 95% CI, −0.03 to 0.04), salivary complications (RD, −0.01; 95% CI, −0.08 to 0.06), and postoperative bleeding (RD, −0.02; 95% CI, −0.07 to 0.04), were all similar between the LS group and the CT group. According to the results, the LS device appears to be a safe and useful tool and could shorten the operative time in patients needing parotidectomy.
