Objective:To investigate the clinical effect of subcutaneous tunnel transfer of forehead thin skin flap supplied by cutaneous branch of supratrochlear artery in repairing skin defect around eyebrow.Methods:From June 2017 to June 2019, 15 patients with eyebrow skin lesion were treated with the aforementioned method at the Plastic Surgery Department of the 2nd Affiliated Hospital of Harbin Medical University. Inclusion criteria: (1)The skin defect area ranged from 1.5 cm×2.0 cm to 2.0 cm×3.0 cm.(2)There was no redness, swelling, skin ulceration, pruritus or pain in the lesions. Based on the patient’s medical history and clinical manifestations before surgery, the lesions were preliminarily diagnosed as benign lesions, and the surrounding tissues of the lesions were good without inflammatory reaction. (3) All patients were treated with tumor resection and repair with thin flap supplied by the cutaneous branch of the supracrochlear artery. (4) Clear consciousness, no intellectual or cognitive impairment, informed consent to this study and willing to cooperate with postoperative follow-up. Patients with other serious systemic diseases were excluded. A thin frontal flap supplied by the cutaneous branch of the supratrochal artery was designed near the hairline of the forehead. The size and shape of the flap should be similar to the size of the lesion. During the operation, the frontal flap was elevated, and the subcutaneous pedicle contained the cutaneous branch of the supratrochlea artery, and the flap was transferred to repair the defect wound through the subcutaneous tunnel. After the operation, the skin flap survival was evaluated by observing the skin flap color and other indicators, and the scar was evaluated by the Vancouver Score Scale(VSS).Results:A total of 15 patients were included, including 2 males and 13 females, aged 12-44 years, and the defect range was 1.5 cm×2 cm-2 cm×3 cm. The flap survived well after operation. In 2 cases, the incision was infected after operation, and the incision healed well after receiving anti-inflammatory treatment and daily dressing change. Local epidermal necrosis occurred in 5 cases, dressing was changed on time, and blood scab was formed. After blood scab shedding, 3 cases had no obvious pigmentation, and 2 cases had mild pigmentation. After 12 months of follow-up, the VSS score was 0-4.All patients were satisfied with the postoperative effect.Conclusions:The thin frontal skin flap can be applied to repair the skin defect around the eyebrow by subcutaneous tunnel transfer. It can be completed in one stage. The scar in the donor area of the flap is hidden, and there is no deformation of the eyebrow and inner canthus, and the survival rate of the flap is high.
