Abstract:
Objective:To observe the efficacy of free transplantation of latissimus dorsi musculocutaneous flap and anterolateral femoral skin flap in repairing the wound after the resection of the scalp squamous cell carcinoma, and to explore the indications of these two skin flaps.Methods:The clinical data of patients with scalp squamous cell carcinoma admitted to the Plastic Surgery Department of the Second Affiliated Hospital of Kunming Medical University from June 2013 to May 2019 were analyzed retrospectively. All patients showed no cancer metastasis examined with CT. None of the patients had systemic diseases such as hypertension, diabetes, vascular disease. The wounds were repaired with free transplantation of latissimus dorsi myocutaneous flaps and anterolateral thigh flaps after extensive tumor resection. The intraoperative vascular variation, the diameter of the anastomosed blood vessel, the length of the vascular pedicle, the flap size, the time of harvesting the flap, the time for anastomosis, the operation time, and the incidences of complications at the donor site and recipient site were measured or recorded in both groups.Results:A total of 21 cases were included, including 14 males and 7 females, aged from 12 to 61 years. Eleven cases were repaired with the latissimus dorsi musculocutaneous flap, and 10 cases with the anterolateral thigh flap. All the 21 flaps survived during the 1 to 2 years follow-up. No vascular variation was found in the latissimus dorsi myocutaneous flap group, whereas 2 cases of vascular variation were found in the anterolateral thigh flap. In the latissimus dorsi myocutaneous flap group, the anastomotic vessel diameter was (2.14±0.09) mm for the artery and (2.49±0.10) mm for the vein. The vascular pedicle length was (6.14±0.28) cm, and the size of the flap was (135.0±20.8) cm 2, the harvesting time was (114.8±3.0) min, the vascular anastomosis time was (20.8±0.8) min, and the operation time was (6.5±0.2) h. In the anterolateral thigh flap group, the anastomotic vessel diameter was (2.15±0.14) mm for the artery and (2.45±0.15) mm for the vein. The vascular pedicle length was (6.80±0.31) cm, and the size of the flap was (159.9±16.4) cm 2, the harvesting time was (119.8±3.6) min, the vascular anastomosis time was (21.5±0.9) min, and the operation time was (6.9±0.2) h. There was no significant difference between the two kinds of flaps in the above parameter. The incidence of total complications at the donor site was higher in the latissimus dorsi myocutaneous flap group (7 cases) than that in the anterolateral thigh flap group (4 cases). The incidence of overall complications at the recipient was lower in the latissimus dorsi myocutaneous flap group (1 case) than that in the anterolateral thigh flap group (2 cases). Conclusions:Both the latissimus dorsi myocutaneous flap and the anterolateral femoral skin flap can achieve good results in repairing the wound after the resection of the scalp squamous cell carcinoma. The latissimus dorsi myocutaneous flap has a constant blood supply, and the operative technique is relatively easy and with low risk, which is more suitable for novices. The anterolateral thigh flap is thin and with fewer complications at the donor site. It is easy to be accepted by patients and can be performed in the supine position, which is more suitable for elderly patients.
