超声刀在开放性下颌下腺手术中的应用

]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。

The application of ultrasonic knife in open submandibular gland surgery

PURPOSE: To study the value of ultrasonic knife in submandibular gland surgery. METHODS: Randomized controlled clinical trial was adopted. Forty cases collected from October 2013 to July 2014 who underwent submandibular gland surgery were divided into experimental group and control group. All cases were operated by the same surgical team. Ultrasonic knife was used in the experimental group, while electric knife was used in the control group. The operation time, intraoperative blood loss, postoperative complications and 24 h and 48 h postoperative drainage volume were recorded and compared between the 2 groups. SPSS 10.0 software package was used to analyze the data. RESULTS: There was no significant difference in age, gender, mass size and disease type between the 2 groups (P>0.05). With the same operative procedure, there was no significant difference in postoperative complications (P>0.05). Compared with the control group, the operation time, intraoperative blood loss and 24 h and 48 h postoperative drainage volume were significantly decreased in the experimental group (P<0.05). CONCLUSIONS: Using ultrasonic knife in submandibular gland surgery is safe and reliable, with distinct advantages over electric knife. The tissue damage is less, and postoperative complications are minimal. It is worth of wide application in oral and maxillofacial surgery.
