Objective To explore the clinical effects of artificial dermis combined with vacuum sealing drainage (VSD) and autologous split-thickness skin graft in repair of scar contracture deformity after extensive burn.
Methods A total of 8 patients with scar hyperplasia and contracture deformity on joint after healing of extensive burn were admitted to our hospital from August 2015 to August 2017. There were 5 females and 3 males aged 8 to 45 years with an average of 23 years. In the first stage operation, scar tissue on contracture site was removed, and the wound was covered by artificial dermis followed by continued VSD treatment. On 10-14 d after the first stage operation, the artificial dermis tissue formed, and the second stage autologous split-thickness skin grafting and continued VSD treatment were performed. Routine anti-scar therapy was carried out after healing of wounds. Time of wound healing after the second stage operation was recorded. Colour and texture of the split-thickness skin graft, scar formation condition of the donor site, and action condition of the operation site during follow-up were observed.
Results The wounds of 8 patients were healed in 10-14 d after the second stage operation. During follow-up of 6-24 months, the split-thickness skin graft was with smooth surface and good elasticity, and the function of joint recovered well. The donor site in head healed well with no scar. Only pigmentation was left in the donor site of thigh, and scar was not obvious. The patients and their family members were satisfied.
Conclusions After application of artificial dermis combined with VSD and autologous split-thickness skin graft in repair of scar contracture deformity after extensive burn, the skin grafting area and donor site were with unobvious scar hyperplasia, and the joint function in the operation area was good.
