目的 :通过对比超声刀与电刀在下颌下腺手术中的效果,探讨超声刀在下颌下腺手术中的临床应用价值。方法:采用随机对照试验,将2013年10月—2014年7月进行的40例下颌下腺手术分为试验组和对照组,2组均由经验丰富的同一手术团队完成。试验组手术过程使用超声刀进行手术,对照组使用电刀进行手术。术后比较2组的手术时间、术中出血量、术后并发症及术后24 h和48 h引流量等指标,采用SPSS 10.0软件包对所得数据进行分析。结果:2组患者的年龄构成、性别、肿块大小及疾病构成比无显著差异(P>0.05);在相同的手术方式下,2组术后并发症无显著差异(P>0.05);试验组手术时间、术中出血量及术后24h和48h引流量较对照组显著减少(P<0.05)。结论:超声刀应用于下颌下腺手术安全可靠,较电刀有明显优势,可明显缩短手术时间、减少术中出血及术后引流量,对组织损伤小,无明显术后并发症,值得在口腔颌面外科手术中推广应用。
Objective: To evaluate the clinical value of ultrasonic knife in submandibular gland surgery by comparing the effect of ultrasonic knife and electric knife in submandibular gland surgery. METHODS: Forty submandibular glands from October 2013 to July 2014 were divided into trial group and control group by randomized controlled trial. Both groups were performed by the same team of experienced surgeons. The experimental group was operated on with an ultrasonic knife and the control group with an electric knife. After operation, the operation time, intraoperative blood loss, postoperative complications and the drainage volume at 24 h and 48 h after operation were compared. The data were analyzed by SPSS 10.0 software package. Results: There was no significant difference in age, sex, mass size and disease composition between the two groups (P> 0.05). There was no significant difference in postoperative complications between the two groups (P> 0.05) The operation time, intraoperative blood loss and drainage volume at 24h and 48h after operation were significantly decreased compared with the control group (P <0.05). Conclusion: The application of ultrasonic knife in submandibular gland surgery is safe and reliable, which has obvious advantages over electric knife. It can shorten the operation time, reduce the intraoperative bleeding and the amount of postoperative drainage. It has less tissue damage and no obvious postoperative complications. Popularization and application of maxillofacial surgery.
