“…These devices allowed a reduction in operative time and a decrease in postoperative complications. [1][2][3][4][5][6] Surgical devices are regularly modified in an effort to improve results. In 2011, the Food and Drug Administration approved the Small Jaw, a new generation of the LigaSure (LS) (Covidien, Mansfield, MA) for use in thyroid 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 in LS, P = .99). Overall complications were similar between both groups (22.86% in HS vs 13.84% in LS, P = .05). However, LS use was also associated with a lower incidence of postoperative transient hypocalcemia as compared to the HS (P = .025). No significant difference was found between both groups regarding the incidence of recurrent laryngeal nerve injury (P = .52). Conclusion The use of the LS is safe, feasible, and is associated with comparable outcomes to HS. Both intraoperative and postoperative variables were similar between both devices. Future larger studies are warranted to further investigate the effect on postoperative transient hypocalcemia.

“…The main advantages of ultrasonic coagulating/dissecting systems compared with a standard electrosurgical device are manifested by minimal lateral thermal tissue damage, less smoke formation, no neuromuscular stimulation, and no electrical energy through the patient[1,2]. This new technology is extensively used in laparoscopic surgery and several fields of minimally invasive surgery [3-5].…”

The aim of this study was to compare operating time, postoperative outcomes, and surgical complications of total thyroidectomy plus level III-IV and VI dissection between the no-tie technique using the Harmonic Focus and classic suture ligation for hemostasis. Fifty-four patients underwent total thyroidectomy plus level III-IV and VI dissection by classic suture ligation and 51 patients by the Harmonic Focus. There was obvious distinction as to the operating time between the Focus and classic group (102.8 and 150.1 minutes, respectively, P < 0.05). Drainage volume (202.7 ± 187.0 mL vs 299.7 ± 201.4 mL, P < 0.05) were significantly lower in the Focus group. Transient hypoparathyroidism had no statistically significant difference between the groups (17.6% vs 18.5%, P > 0 .05). No patient experienced nerve injury or permanent hypocalcemia. The use of Harmonic Focus for the control of thyroid vessels during thyroid surgery is reliable and safe. The device can offer extraordinary capabilities for delicate tissue grasping and dissection.

“…17 The articulating jaw compresses tissue against the vibrating shaft to impart the tissue effects. 18 The Harmonic ACE is associated with greater increases in peak temperatures at the instrument tip compared with the older model, 18 and so results from studies performed using the older model cannot be directly extrapolated to the current model. Vessel-sealing tissue effects are essentially the same as those obtained with advanced bipolar electrosurgery, namely, desiccation and coagulation with resultant coaptation.…”
