Comparison of modified pectoralis major myocutaneous musculocutaneous flap and traditional flap for postoperative repair of tongue cancer

Abstract

Objective To investigate the practical value of modified pectoralis major myocutaneous musculocutaneous flap and traditional flap for postoperative repair of tongue cancer. Methods Forty-eight patients with tongue cancer in the First Affiliated Hospital of Zhengzhou University from September 2016 to June 2018 were randomly divided into study group and control group, with 24 cases in each group. The patients in the study group underwent continuous resection of the pectoralis major muscle flap after continuous mass excision. The patients with tongue cancer in the control group underwent continuous mass resection and traditional flap repair. Surgery, repair and incidence of adverse reactions were compared between the two groups. Results The operation time of the study group was significantly lower than that of the control group (P>0.05). The healing time of the study group was significantly lower than that of the control group (P<0.05). The total effective rate of the study group (95.83%) was significantly higher than that of the control group (70.83%, P<0.05). The incidence of postoperative upper arm dyskinesia, infection, and edema after flap transplantation were significantly lower in the study group (0, 4.17%, 4.17%, respectively) than those in the control group (29.17%, 100.00%, 25.00%), the differences were statistically significant(P all <0.05). Conclusions Modified pectoralis major myocutaneous island flap in repair for tongue cancer patients has satisfactory therapeutic effects.
