Abstract

Abstract : Summary: Both internal and external tissue expanders take advantage of the innate adaptive mechanisms the skin exerts in response to mechanical tension, known as the stress-relaxation phenomenon. Internal tissue expander use is time-consuming and can be complicated by infection and extrusion. In this case series, continuous external tissue expanders used to manage large pediatric wounds were assessed. Fourteen patients (ages: 4 days to 17 years) with large wounds underwent continuous external tissue expansion intraoperatively. The success of wound closure was assessed. In addition, the size of the patient's wounds, duration of device application, and postoperative complications were evaluated. The continuous external tissue expander was applied to wound sizes ranging from 14.7 to 560 cm 2 for 5 to 10 days until the wound was amenable for direct closure. In 11 of the 14 patients, delayed primary closure was achieved. The device significantly reduced the wound sizes of the remaining three cases (average 80% size reduction). There was no incidence of wound dehiscence or infection. This case series demonstrates the benefit of the continuous external tissue expansion in managing pediatric wounds that would not otherwise be amenable to primary closure. The method allows for timely closure with limited risk of infection or extrusion, and should be in the armamentarium of reconstructive plastic surgeons.
