The Logical Classification Of The Basic Techniques Of Skin Plastic Surgery And Its Clinical Application In The Repair Of Soft Tissue Defect In Oral And Maxillofacial Region

ObjectiveTo explore the applying value of ultrasonic scalpel in reconstruction of oral and maxillofacial soft tissue defects with flaps.MethodsIn this study,35 cases from January 2014 to December 2016 were collected in the First Affliated Hospital of Soochow University.Myocutaneous flaps were used in all of cases to reconstruct defects of oral and maxillofacial soft tissue.Among them,the surgeries in which ultrasonic scalpel was applied were defined as research group.On the other hand,conventional surgeries with electric scalpel and steel surgical scalpel were defined as control group.Several evaluation indexes were studied,including operation time,intraoperative blood loss,as well as the volume of postoperative drainage fluid.Meanwhile,the postoperative recovery,the flap survival rate and complications were observed.Results1.The duration of operation in research group was 470.05±138.45 min,while it was 488.88±150.46 min in control group(p>0.05,showing no significant difference).2.The intraoperative blood loss in the research group was 523.68±367.46 m L,while it was 668.75±483.00 m L in control group(p>0.05,showing no significant difference.3.The volume of postoperative drainage fluid in research group was 85.63±238.44 m L,while it was 95.19±126.62 m L in control group(p>0.05,showing no significant difference).There was no significant difference in postoperative recovery,flap survival rate and complications.ConclusionWhen ultrasonic scapel was applied in the flap trasplantation surgeries to repair oral and maxillofacial soft tissue defects after tumor resection,there was no statistic diference shown in operation time,intraoperative blood loss,volume of drainage fluid,as well as flap survival rate and complications comparing with conventional surgical instruments.
