Autologous scalp repair of wounds in the medium-thickness skin donor area:safety and effectiveness
BACKGROUND:Large deep burn wounds are often accompanied by scar hyperplasia after healing,requiring transplantation of medium-thickness skin for repair,and the medium-thickness skin slices taken generally reach below the papillary layer of the dermis.If not handled correctly,complications such as delayed healing,ulceration,and post-healing pain and itching in the donor area can easily occur.Therefore,the repair of wounds in the donor area should be emphasized.OBJECTIVE:To observe the safety and practicability of autologous scalp repair of skin donor area in patients with deep burns and scarring.METHODS:Sixty patients with deep burn and scar hyperplasia admitted to the Burn Department of Zhengzhou First People's Hospital from January 2021 to September 2023 were selected as the study subjects.They all needed medium-thickness skin transplantation and repair,and were divided into study group(n=30)and control group(n=30)according to random systematic sampling method.The skin was taken from the patient's own medium-thickness skin on the leg or back.In the study group,the skin donor area was repaired with self-blade thick scalp replantation,and in the control group,the skin donor area was repaired with absorbent dressing.The wound healing rate and the time to complete epithelialization of the wound were observed and compared in the two groups 6 days after surgery.The pain of dressing change at 3 and 6 days after surgery and scar hyperplasia in the skin donor area at 6 months after surgery were compared between two groups.RESULTS AND CONCLUSION:Compared with the control group,the time to complete epithelialization of the wound was significantly lower in the study group(P<0.05),and the wound healing rate was significantly higher in the study group(P<0.05),the pain score for dressing change at 3 and 6 days after surgery was significantly lower in the study group(P<0.05),and the scar hyperplasia rate,scar score and itch score were also significantly lower in the study group(P<0.05)at 6 months after surgery.In conclusion,autologous scalp repair of the medium-thickness skin donor area can accelerate wound healing and reduce scar hyperplasia.
