Abstract: PURPOSE: To explore the feasibility and practicability of ultrasonic scalpel in the preparation of fibular osteomyocutaneous free flap. METHODS: From September 2019 to March 2022, 62 patients who needed fibular osteomyocutaneous free flap to repair head and neck defects in the Department of Oral and Maxillofacial Surgery, Affiliated Hospital of Qingdao University were collected. In the experimental group, fibular osteomyocutaneous free flaps were prepared by ultrasonic scalpel(n=30); while in the control group, fibular osteomyocutaneous free flaps were prepared by traditional monopolar electrotome(n=32). The preparation time of fibular osteomyocutaneous free flap, total intraoperative blood loss, blood loss of fibular donor site, drainage volume of fibular donor site, drainage days of fibular donor site and other surgery-related indexes were compared. The levels of tumor necrosis factor (TNF-α) and interleukin-6 (IL-6) in the postoperative drainage fluid were also compared. At the same time, postoperative complications (bleeding, edema, flap necrosis) and postoperative fibula donor site pain score were compared. SPSS 25.0 software package was used for statistical analysis. RESULTS: In the experimental group, the blood loss from fibular donor site was significantly decreased(P<0.01), and the preparation time of fibular osteomyocutaneous free flap, the total intraoperative blood loss, the drainage volume of fibular donor site, and the drainage days of fibular donor site were significantly decreased(P<0.05). The levels of TNF-α and IL-6 in the drainage fluid of the experimental group were significantly decreased(P<0.01). There was no significant difference in the incidence of postoperative complications between the two groups(P>0.05). In addition, there was no significant difference in the pain score of the fibular donor site on the first day after operation between the two groups(P> 0.05), but the pain score of the fibular donor site in the experimental group was significantly decreased from the second day to the fifth day after operation(P<0.05). CONCLUSIONS: The preparation of fibular osteomyocutaneous free flap assisted by ultrasonic scalpel has less damage and better postoperative recovery for patients than traditional monopolar electrotome. Hemostasis with ultrasonic scalpel during operation has a good clinical application prospect in oral reconstructive surgery.
