The ultrasonic scalpel instrument was compared with the conventional staphylectomy technique in elongated soft palate surgery in twenty brachycephalic airway obstructive syndrome (BAOS) canines. Patients were randomly divided into the conventional incisional and ultrasonic scalpel group. Operation time (minute), bleeding volume (ml), respiratory distress score, postoperative complications score, pain scores, epithelialization score and inflammatory score were assessed. Two weeks after surgery, soft palates tissues were biopsied from 7 conventional surgery dogs and 8 ultrasonic dissection device applied dogs. The operation time and bleeding volume in the conventional surgery group were significantly higher than that in conventional group (P<0.01 and P<0.001, respectively). In addition, the respiratory distress score was significantly higher in the conventional surgery group compared with the ultrasonic dissection device group on day 3 and day 28 post-operation (P<0.05). There were no significantly different postoperative complication scores, pain scores or inflammatory scores between two groups. The epithelialization score of the UD was significantly higher than that of the conventional group (P<0.05). The ultrasonic dissection device is user friendly, has decreased surgical time, complete hemostasis and provides fewer postoperative complications. The ultrasonic dissection device is recommended in high-risk patients such as those displaying senility, chronic inflammation, or bleeding disorders.
