Ligusure-assisted Neck Dissection
The study group patients were treated using the LigaSure vessel sealing system (Small Jaw® with ForceTriad®; Covidien, Colorado, USA) for dissection and hemostasis throughout the whole procedures during neck dissection. Ligasure small jaw (Covidien, Colorado, USA): The Small Jaw® handpiece (Small Jaw® with ForceTriad®; Covidien, Colorado, USA) was not only used as a dissection forceps but also served as a ligation device.
Conventional Neck Dissection
The control group patients were treated using conventional cold instrument dissection, monopolar electrocautery hemostasis, and suture ligation during neck dissection.
