ABSTRACT
Objective@#To explore the excellent methods for aesthetic repair of the donor sites of flaps.@*Methods@#From January 2013 to March 2018, 120 patients (94 males and 26 females, aged from 3 to 60 years) were admitted to the Department of Burns of Beijing Jishuitan Hospital. Wounds areas after debridement or removing scar were ranged from 8.0 cm×3.5 cm to 24.0 cm×18.0 cm. Twenty patients with facial and neck scar were repaired with expanded flaps, including 4 scalp flaps, 8 supraclavicular flaps, 4 deltoid flaps, and 4 trapezius myocutaneous flaps. The flaps in ideal donor sites were selected to repair the wounds in 40 patients, including 20 cases of hand wounds or scars repaired with inguinal flaps, 10 children of foot skin defects or scars repaired with cross inguinal skin flap, 10 cases of knee joint wounds repaired with medial or lateral thigh flaps. The optimal flap design was used to repair wounds in 50 patients. Among the patients, wounds of 36 patients were repaired with relaying flaps, including donor sites of free anterolateral thigh flaps of 8 patients repaired with anteromedial thigh perforator flaps and donor sites of free anterolateral thigh flaps of 8 patients repaired with ilioinguinal flaps or superficial abdominal artery flaps, and donor sites of flaps of 20 patients repaired with peroneal perforator relaying flaps. Besides, wounds of 9 patients were repaired with free lobulated anterolateral thigh flaps, and wounds of 5 patients were repaired with modified V-Y propelling latissimus dorsi myocutaneous flaps. The donor sites of flaps were repaired with allogenic acellular dermal matrix combined with autologous split-thickness skin grafts in 10 cases. The areas of the flaps or myocutaneous flaps were ranged from 6.0 cm×4.0 cm to 30.0 cm×20.0 cm. The survival of flap, myocutaneous flap, or skin graft and the repair of donor site after operation and during follow-up were observed.@*Results@#Blood flow obstacle at 0.5 cm to the distal margin of the flap occurred in 1 patient repaired with expanded flap, which were healed after dressing change. Blood supply disorder occurred at the tip of the anteromedial thigh perforator flap of 1 patient repaired by optimal flap design, which were healed completely after second debridement and restitching. The other flaps or myocutaneous flaps survived well. The allogenic acellular dermal matrix and the autologous split-thickness skin graft survived with good color and texture. During follow-up of 3 months to 4 years, the donor sites of flaps had good appearance, only with linear scar and the function recovered well. The donor sites of skin grafts had no scar hyperplasia, only with scattered pigmentation.@*Conclusions@#According to the characteristics of donor sites of flaps, individualized and reasonable design before the operation such as pre-expanding of the flaps, selecting the ideal donor sites, optimization of the flap design or allogenic acellular dermal matrix combined with autologous split-thickness skin graft to repair donor sites of flaps can minimize the damage for function and appearance of donor sites of flaps and achieve aesthetic effects of donor sites of flaps.
ABSTRACT
Objective@#To explore the choice of the donor site of flap and the repair method of secondary wound of flap donor site in tissue repair and reconstruction operation.@*Methods@#From January 2014 to September 2018, 62 cases of scar contracture deformity, 15 cases of skin tumor, 20 cases of skin and soft tissue injury, and 25 cases of chronic wound were admitted to the Burn Center of People′s Liberation Army of First Affiliated Hospital of Air Force Medical University, with 84 males and 38 females, aged from 3 to 89 years. Four repair strategies adopted for tissue repair and reconstruction and good repair of the donor site of flap were as follows: designing the flap rationally according to the condition around the wound or the size and shape of wound, choosing pre-expanded technique of the donor site of flap for repair of scar deformity optimally, making full use of the surrounding condition of flap donor site, and repaired with the distal flap, i. e. replacing the important site with secondary site. The donor site of flap was repaired by direct suture or peripheral flap and distal flap. The wound size of patients ranged from 3.0 cm×2.0 cm to 20.0 cm×18.0 cm, and the flap area ranged from 3.5 cm×2.0 cm to 25.0 cm×22.0 cm. The survival condition of flap, healing condition of donor site and recipient site, and follow-up condition of donor site and recipient site were recorded.@*Results@#Wounds of 122 patients were repaired with a total of 148 flaps designed by the above four repair strategies. All the flaps survived well, and the wound and flap donor site healed well. Follow-up for 3 to 36 months showed that the shape and function of recipient site and flap donor site were satisfactory.@*Conclusions@#According to the specific condition of the wound and anatomical structure of the surrounding tissue of flap donor site, overall surgical design with flexibility and personalization can achieve effects of good repair of the wound and reduce the secondary damage of flap donor site.
ABSTRACT
Skin graft and flap are common tools for wound repair, but donor site would be damaged when harvesting skin graft or flap. If donor site treatment is ignored, various problems concerning the appearance and function of donor site will appear. Therefore, when choosing skin graft or flap, donor site treatment should be considered as an important factor. We should not only seek for the repair effect of recipient site but ignore adverse effect on donor site. We should comprehensively weigh the pros and cons between donor site and recipient site. And paying the lowest price of donor site to achieve the best repair effect of recipient site should be the essential requirement to choose skin graft or flap. For wound cosmetic repair, how to achieve cosmetic repair of donor site should be considered. In recent years, donor site treatment of skin graft and flap has drawn widespread attention and achieved some progress. But compared with cosmetic repair, there still exists some gap. The objective to publish this special topic is to further lay emphasis on the cosmetic repair of donor site by introducing some domestic studies about cosmetic repair of donor site.
