Long-Term Outcome of Free Rectus Abdominis Musculocutaneous Flap for General Soft-Tissue Reconstruction

PURPOSE: The rectus abdominis musculocutaneous (RAM) flap has contributed to the efficient reconstruction of soft tissue defects. The flap has the advantage of easy dissection, minimal donor site morbidity, and the constant vascular anatomy with long pedicle. Authors used the free RAM flap to reconstruct multi-located soft tissue defects while still considering functionality and aesthetics. We present the long-term outcomes and versatility of free RAM flaps. MATERIALS AND METHODS: From 1994 to 2004, all patients who underwent soft tissue reconstruction with free RAM flap were reviewed retrospectively. The site of the reconstruction, vessels of anastomosis, type of RAM flap, and outcomes, including flap success rate, hospital stay after flap transfer, conduction of secondary procedure, flap complications, and donor-site complications were analyzed. RESULTS: Twenty-one patients underwent 24 free RAM flaps in site of breast, face, upper extremity and lower extremity. Mean follow-up period was 36.1 months (range, 3~156 months). The overall success rate was 92% with only a loss of 2 flaps. Minor complications related to transferred flaps were necrosis of 2 partial flaps, hematoma formation in 3 cases, and a wound infection in 1 case. Donor site morbidity was not observed. Debulking surgery was performed in 4 patients, and scar revision was performed in 3 patients. CONCLUSION: Free RAM flap is a workhorse flap for general soft-tissue reconstruction with minimal donor site morbidity with aesthetically good results. Thus, the free RAM flaps are versatile, and sturdy for any sites of soft-tissue where reconstruction could be performed.

Split-Thickness Skin Grafting with Meshed Matriderm(R) in Burn Wound Management

PURPOSE: Skin graft is the gold standard surgical treatment in burn wound management. But it has functional and aesthetic limitations, such as burn scar contracture, low quality of the grafted skin, unnatural looking skin, loss of skin elasticity, especially in extensive deep burn wound which has tendon or bone exposed. The authors used Matriderm(R), a dermal analogue, with split-thickness skin graft simultaneously in burn wound and evaluate the effectiveness of Matriderm(R) for treatment of burn wounds, in comparison with the skin graft only. METHODS: 40 burn patients with skin graft were included in this study. Patients were selected with their consent for inclusion in an experimental group and a control group. Patients in the experimental group received a meshed Matriderm(R) appliance and a split-thickness skin graft, while those in the control group received only a split-thickness skin graft. Time to complete epithelization, rates of skin graft taken areas, Vancouver scar scale assessment, skin elasticity was evaluated. RESULTS: A better scores of Vancouver scar scale assessment (3 points) were observed in the experimental group with the control group (6 points) with statistical significance (P<0.05). A higher elasticity ratio of the affected side to the non-affected side was observed in the experimental group, compared with the control group (P<0.05), and a similar time to complete epithelization and rates of skin graft taken areas were observed in the experimental group when compared with the control group. CONCLUSION: Meshed Matriderm(R) enables effective healing and improves functional and aesthetic results in split thickness skin graft treatment of burn wounds.

Vacuum-Assisted Closure (VAC) as a Dressing Method for Skin Graft in Burn Wound Management

PURPOSE: Skin graft is the gold standard surgical treatment in burn wound management. Until now, wet to dry dressing is regarded as the traditionally standard dressing for skin graft. But it needs to be changed daily, burdens the patients and medical caring team and is time consuming. The authors apply VAC to skin graft to secure the skin and compared the outcomes with previous standard dressing technique. METHODS: 38 burn patients who underwent skin graft were included in this study. Patients were selected with their consent for inclusion in an experimental group and a control group. Patients in the experimental group received a VAC appliance after split-thickness skin graft, while those in the control group received wet to dry dressing after the procedure. Time to complete epithelization, rates of skin graft taken areas, satisfaction of patients and medical caring team was evaluated. RESULTS: A shorter time to complete epithelization (12.5 days) was observed in the experimental group than in the control group (14.6 days), and a higher rates of skin graft taken areas (89%) was observed in the experimental group when compared with the control group (84.5%), A higher satisfaction of both the patients and doctors was observed in the experimental group, compared to the control group, with all statistical significance (P<0.05). CONCLUSION: VAC shortens epithelization period and elevate skin graft taken rates. It also makes the patients and doctors the comfortable in burn patients. The VAC is an excellent alternative for securing skin graft.

Treatment of Facial Abrasion using Amnisite BA(R)

PURPOSE: Facial abrasions have been treated by moist occlusive dressing for many years. But previous dressing methods have several disadvantages such as difficulty of fixation due to varied contours, too frequent dressing changes with pain, discomfort due to volume of the dressing materials. The authors applied dried bovine amniotic membrane (Amnisite BA(R)) to facial abrasions as a new therapeutic option and compared its efficacy with previous foam dressing treatments. METHODS: From June 2010 to May 2011, thirty two patients suffering from facial abrasions were included in this study, with a mean age of 32.4. Patients were divided into two groups by patient preference. One group was treated with dried bovine amniotic membrane while the other group was treated with ointment and foam dressings. Subjects were followed by regular outpatient clinic visits until complete epithelization. Healing time, treatment costs, scar formation, skin elasticity and moisture content were evaluated to compare the efficacy of dried bovine amniotic membrane in comparison to foam dressing groups. RESULTS: All of thirty two patients were well healed after appliance of dried bovine amniotic membrane or foam dressing without any complication. The healing time for patients treated with dried bovine amniotic membrane was significantly shorter (P<0.05) and no significant difference between the two groups regarding treatment costs, scar formation, skin elasticity or moisture content was shown. CONCLUSION: Facial abrasion can be effectively treated with dried bovine amniotic membrane with a shortening of epithelization period and similar effectiveness as previous foam dressings. In addition, dried bovine amniotic membranes have several benefits. easy appliance to any parts of face, reducing the frequency of dressing changes, early adaptation to social life and so on, These presented benefits make this material a new standard for treatment of facial abrasion.
