Clinical effects of skin soft tissue expansion in treatment of scars and nevus / 中华医学美学美容杂志

ABSTRACT

Objective:To explore the choice of skin flap design and clinical effects of skin soft tissue expansion in the treatment of body surface lesions.Methods:From January 2018 to December 2020, the Department of Plastic Surgery, the First Affiliated Hospital of the Air Force Medical University performed skin and soft tissue expansion in 148 patients with scars and nevus, including 83 males and 65 females. The age ranged from 4 to 52 years. According to the distance of the donor area, the expanded flap was divided into adjacent local flap and distal pedicled axial flap. An appropriate volume expander was embedded under the donor area flap. The expander was expanded regularly for 8-24 weeks, and the displacement of expander and other complications were avoided.Results:A total of 212 dilators were implanted in 148 patients, and the damaged area was completely repaired after 1 or 2 dilation operations. The expanded flaps were effectively used. The flap transfer was consistent with the first-stage design, with fewer auxiliary incisions, hidden and inconspicuous scars, and maximum repaired area was 22 cm×18 cm; the incidence of dilator complications (16 cases with 21 dilators) was 9.90%.Conclusions:Paying attention to the reasonable design and selection of flap in stage Ⅰ operation can make effective use of expanded flap in stage Ⅱ operation, fully repair body surface lesions, reduce auxiliary incision and achieve the best repair effect.
