ABSTRACT
Objective: To compare the curative effects of butterfly-shaped flap based on the dorsal branch of digital artery (hereinafter referred to as butterfly-shaped flap) and propeller flap based on the dorsal branch of digital artery (hereinafter referred to as propeller flap) in repairing the wound in volar aspect of finger. Methods: A retrospective cohort study was conducted. From August 2018 to April 2022, 16 patients with finger palmar wounds admitted to Ruijin Hospital of Shanghai Jiao Tong University School of Medicine and 7 patients with finger palmar wounds admitted to General Hospital of PLA Central Theater Command met the inclusion criteria, including 14 males and 9 females, aged 25 to 64 years. After debridement or resection of skin benign tumor, the wounds ranged from 0.5 cm×0.5 cm to 1.5 cm×1.5 cm. According to the different rotation axes of flap pedicle during wound repair, the patients were divided into butterfly-shaped flap group (8 cases) and propeller flap group (15 cases), and their wounds were repaired by butterfly-shaped flap (with area of 0.5 cm×0.5 cm-1.5 cm×1.3 cm) or propeller flap (with area of 0.7 cm×0.5 cm-1.5 cm×1.5 cm) , respectively. In propeller flap group, wounds in the donor sites were repaired by full-thickness skin grafts taken from the palms of wrists or the groin. The surgical time, postoperative complications, flap survival, and wound healing time of patients in the two groups were recorded. Data were statistically analyzed with independent sample t test, Mann Whitney U test, or Fisher’s exact probability test. Results: The surgical time and postoperative wound healing time of patients in butterfly-shaped flap group ((43±9) min and (13.1±0.8) d, respectively) were both significantly shorter than those in propeller flap group ((87±16) min and (16.7±4.6) d, respectively, with t values of -7.03 and -2.86, respectively, P<0.05). The postoperative flap survival and complications of patients between the two groups were both similar (P>0.05). Conclusions: For repairing the wound in volar aspect of finger, the butterfly-shaped flap has more advantages in comparison with the traditional propeller flap. The butterfly-shaped flap has a short surgical time and fast postoperative recovery, which is worthy of clinical promotion.
