[Application of delayed skin-stretching device in treatment of skin and soft tissue defects].

Objective: To summarize the effectiveness of delayed skin-stretching device in treatment of skin and soft tissue defects. 方法: 2014 年 12 月—2016 年 12 月，采用延时皮肤牵拉器治疗皮肤软组织缺损 10 例。男 6 例，女 4 例；年龄 42～64 岁，平均 53 岁。急性创伤致皮肤软组织缺损 6 例，骨筋膜室综合征切开后切口无法闭合 3 例，巨大痈切开引流后皮肤软组织缺损 1 例。缺损部位：大腿 4 例，小腿 3 例，上臂 2 例，背部 1 例。缺损范围为 10 cm×4 cm～22 cm×12 cm。创缘行 Pinch 试验，确认创面均无法直接闭合。 Results: Tension blisters were found in 3 cases during traction, and no complications such as impaired blood circulation or skin necrosis occurred in all cases. Skin defects closed directly after continuously stretching for 7-18 days. No skin graft or free flap repair was performed in all patients. The wound healed well after operation. All the 10 patients were followed up 5-8 months (mean, 6.5 months). There was no necrosis around the wound margin and the scar was linear. The sensation and function were not affected. Conclusion: Delayed skin-stretching device is an effective method to treat skin and soft tissue defects, which has the advantages of simple operation, lower risk of operation, less complications, and reliable effectiveness.
