Objective: To evaluate the role of the Ligasuretrade mark Vessel Sealing System (LVSS; Valleylab, Boulder, CO) in parotid surgery.
Study design: A prospective study was conducted on 12 consecutive patients undergoing superficial parotidectomy, performed by using the LVSS device as the primary means of ligation. Inclusion criteria included parotid mass with no preoperative suspicion of malignancy, and no extension to the deep lobe of the parotid gland. Efficacy of hemostasis, cut-closure time, and postoperative complications were assessed. Results were compared with a historical control group, including cases on which the LVSS was not available.
Results: LVSS proved effective in providing ligation and hemostasis. There was a mean time gain of 52 minutes, compared with our historical control group. No postoperative bleeding, seroma, salivary fistula, or Frey syndrome were observed. One case of transient facial weakness occurred, which was completely resolved within 6 months.
Conclusion: LVSS is a safe device for parotid gland surgery, providing sufficient hemostasis and reducing operative time.
