Is the use of harmonic scalpel for neck dissection useful? Literature search did not show a single, prospective, randomised control trial. We intended to study the role of harmonic scalpel in neck dissection and compare it with conventional electrocautery technique for oral cavity carcinoma.
40 patients undergoing selective neck dissection for primary oral cavity malignancy were enrolled in this study. The harmonic scalpel (HS) group consisted of 20 patients, and the electrocautery technique (ET) group comprised of 20 patients. The following variables were examined: intraoperative blood loss, operative time, number of ligatures used, postoperative drain, and postoperative hospital stay.
Intraoperative blood loss was found to be significantly reduced in harmonic scalpel group as compared to electrocautery group. However, we found no difference in other parameters like operative time, postop drain, postoperative hospital stay and number of ligatures used between both groups.
Harmonic scalpel for neck dissection is associated with significantly lesser intraoperative blood loss as compared to electrocautery. There is no effect on operative time and postoperative hospital stay in both groups.
使用谐波手术刀进行颈部清扫术是否有用？文献检索未发现单一的前瞻性随机对照试验。我们旨在研究谐波手术刀在颈部清扫术中的作用，并将其与口腔癌的传统电灼技术进行比较。
本研究纳入了40例因原发性口腔恶性肿瘤接受选择性颈部清扫术的患者。谐波手术刀（HS）组由20例患者组成，电灼技术（ET）组由20例患者组成。检查了以下变量：术中失血量、手术时间、结扎线使用数量、术后引流情况和术后住院时间。
与电灼组相比，谐波手术刀组的术中失血量显著减少。然而，我们发现两组在手术时间、术后引流、术后住院时间和结扎线使用数量等其他参数上没有差异。
与电灼相比，使用谐波手术刀进行颈部清扫术术中失血量明显较少。两组的手术时间和术后住院时间均无影响。
