Abstract:
Objective:To explore the application effect of sustainable skin-stretching device in scalp and soft tissue defect.Methods:From June 2017 to January 2020, 5 patients (3 males and 2 females, aged 31-57 (38.0±2.1) years) with large area of scalp and soft tissue defect and skull exposure were admitted to Department of Reparative and Reconstructive Surgery of the Second Hospital of Dalian Medical University. The wound area ranged from 16.0 cm×8.0 cm to 18.0 cm×12.0 cm. The sustainable skin-stretching device was installed after debridement operation for scalp wound. The wound was stretched from the 3rd day after installation of the device, at a basic speed of 1 mm/d and finished for 3 times on average. During stretching, close attention was paid to the changes in blood flow of the wound margin and the subjective feeling of the patients. When the result was negative in the squeezing and pinching test for wound margin after stretching, the further stretching was stopped, the final stretching state was maintained for 3 days, and the wounds were sutured directly. The wound healing during stretching of sustainable skin-stretching device and the occurrence of complications were observed. The rest wound areas after stretching for 5, 10, 15, and 20 days were measured. The wound healing and hair growth were observed during follow-up.Results:All the wounds of 5 patients was sutured directly after stretching for 19-23 d. There was no tension blister on the margin of wounds during stretching, and the margin of wounds healed well after being sutured without skin necrosis. After stretching treatment for 5-20 d, the wound areas were gradually decreased. During follow-up of 2-11 (4.5±1.5) months, the elasticity, color, feeling, and regenerated hair growth of the stretched scalp tissue were close to those of the surrounding normal skin tissue. The linear scar formed on the margin of wounds, but no scar formed on the wounds.Conclusions:The application of sustainable skin-stretching device can reduce the difficulty in repairing scalp and soft tissue defect, with the regenerated hair growing well after treatment, which is worthy of clinical promotion.
