A Prospective Study Comparing the Efficacy and Surgical Outcomes of Harmonic Focus Scalpel Versus LigaSure Small Jaw in Thyroid and Parathyroid Surgery

Background. The use of sealing devices has been established in thyroid surgeries. Recently, LigaSure Small Jaw (LS), a new device that utilizes bipolar energy, was approved by the Food and Drug Administration for use in different head and neck procedures. The purpose of this study is to assess the efficiency and safety of LS use in thyroid surgery compared to Harmonic Focus Scalpel (HS), a well-established device. Methods. A prospective study was conducted to compare the efficacy of LS versus the HS. We evaluated 301 patients who underwent surgery at a North American academic institution. Patients were allocated into two groups according to LS or HS use. All patients underwent vocal cord assessment using direct laryngoscopy preoperatively and postoperatively. Analyses were performed to examine the difference in perioperative outcomes resulting from the utilization of either device. Results. No difference was seen in operative time between both groups (124.20 ± 68.44 minutes in HS vs 125.20 ± 72.13 minutes...
