Supraclavicular Artery Flap versus Skin Graft: Which Is a Better Reconstructive Tool for Managing Post-Burn Contractures in the Neck

BACKGROUND Burn in developing countries still has high burden of inadequately managed severe burns. This study compared supraclavicular artery flap and skin graft in managing neck post-bum contractures. METHODS In National Institute of Rehabilitation Medicine and Pakistan Institute of Medical Sciences, Islamabad, Pakistan, 30 patients with neck post-burn contractures were enrolled. Half of patients randomly underwent supraclavicular artery flap and half received skin graft. The outcome measures including initial improvement in neck extension, patient's satisfaction with color-texture-match and recurrent contracture formation rate were assessed. RESULTS Among patients, 80% were female and 20% were male. Preoperatively, each group had post-burn contractures of grade II among 26.66% of patients, grade III among 60% and grade III among 13.3%. Postoperatively after three months in the two groups, 86.66% improved to grade I and 13.3% improved to grade II. Patient's satisfaction with color-texture was 84.66% in supraclavicular artery flap group, whereas it was 42.66% for skin graft group. Complications were hypertrophic scar at donor site (13%) and flap tip necrosis (6.66%) in supraclavicular artery flap group. In skin graft group, partial skin graft loss was noticed among 33% of patients and delayed healing of donor site among 20%. The recurrent contracture formation rate at one year was 73.33% in skin graft group, whereas there was no case of recurrent contracture in supraclavicular artery flap group. CONCLUSION Supraclavicular artery flap was superior to skin graft in managing post-burn neck contractures. It provided better color-texture match and was associated with no recurrence of contracture formation.
