An alternative dressing for skin graft immobilization: negative pressure dressing

The key difficulty of skin grafting is keeping the graft immobilized on uneven surfaces involved with motion, such as the nuchal area, axilla, web spaces, and the perineal area. This study reports the development of a new idea of negative pressure dressing (NPD) to maintain good immobilization of the skin graft and, at the same time, not cause any significant distress in the patients daily life. Furthermore, the components of this dressing are available in ordinary hospitals. In this report, there are eight cases of skin grafts which were applied by this method, and the average success rate was approximately 97%. Therefore, use of negative pressure dressings to safeguard immobilization of the skin graft is an appropriate alternative method for grafts on uneven or mobile surfaces.

Endoscopic excision of benign tumors in the forehead and brow.

Twenty-five cases of benign tumor of the forehead and brow were excised successfully with endoscope-assisted surgery. The access incision was selected strategically behind the front hairline. For tumors in the middle of the forehead, the tumor was approached by subgaleal dissection. For those in the brow or temporal area, the dissection plane was just superficial to the deep temporal fascia. Patient age ranged from 3 to 59 years. The mass varied in size from 1.0 × 0.5 to 2.0 × 2.0 cm. There were 18 lipomas, 6 dermoid cysts, and 1 pilomatricoma. There was no residual mass or recurrence 1 to 24 months postoperatively. There was no paresthesia or numbness in the scalp. Patients and their families were greatly satisfied with this operation and the absence of visible scarring.

The soft-tissue shaving procedure for deformity management of chronic tophaceous gout

Gout is a condition characterized by the deposition of monosodium urate crystals in the joints or soft tissue. A gouty tophus occasionally mimics an infectious or neoplastic process. However, the conventional enucleating procedure might cause complications. In severe cases, skin necrosis and tendon or joint exposure can occur after debridements. In this series, the soft-tissue shaver is used for deformity management of the chronic tophaceous patients and the results are encouraging. From November 2000 to August 2002, 17 patients with chronic tophaceous gout were treated by the shaver technique. Suction and irrigation were performed simultaneously while the shaver was operating, and chalky deposits of sodium urate could be removed efficiently. Skin necrosis was minimized by means of proper incision planning. Also, bedside debridements and wound wet dressing were helpful for improving the outcomes. The families and patients were satisfied with the results. In conclusion, severe chronic tophaceous gout can be a surgical challenge. The soft-tissue shaving technique can be useful for cosmetic debulking of large tophi in patients with advanced chronic tophaceous gouty arthritis.

The use of composite acellular allodermis-ultrathin autograft on joint area in major burn patients--one year follow-up.

Scar contracture is a major long-term sequelae of meshed split-thickness skin grafts in the case of full-thickness burn injuries, and especially in joint areas. Severe contracture around joints may lead to loss of mobility. The thickness of the dermis in the autograft plays a major role in the functional and cosmetic outcomes of the third degree burn. How to replace lost dermis is a major problem in skin restoration following severe burns. The human allograft skin (AlloDerm) is an acellular dermal matrix with normal collagen bundling organization and intact basement membrane complex. We present 12 cases of clinical application of a composite grafting technique in which the allogeneic skin (AlloDerm) provided source of dermis, and an ultrathin autograft (0.004-0.006 inch in thickness) provided epidermis. In these patients, The composite grafts were applied to full-thickness burn wounds over various articular skin surfaces. The average skin graft take rate was 91.5%. These ultrathin autografts allow the donor sites to heal faster. The mean time of donor site reepithelization was 6 days. All patients had a nearly normal range of joint motion (average 95% of normal) after one years follow up. Wound assessment over time has shown supple skin that has been resistant to trauma and infection. The cosmetic results were judged to be fair to good by surgeons and patients after one years follow up.

Continuous intra-arterial infusion therapy in hydrofluoric acid burns.

To determine the effect of continuous intra-arterial calcium gluconate infusion therapy on patients suffering from hydrofluoric acid dermal burns of the digits, clinical treatment was performed prospectively on 10 patients from January 1997 to December 1998 at the burn care unit of Kaohsiung Medical University Hospital. An arterial catheter was inserted transcutaneously through the radial artery of the involved hand. After confirmation of the proper position of the catheter, calcium gluconate was infused continuously with an ambulatory infusion pump. Rapid pain relief was achieved immediately after infusion. The rate of infusion was then tapered down gradually, and treatment was completed with no major therapeutic complication. All injured digits of these 10 patients were successfully salvaged with good cosmetic appearance and complete functional preservation. Compared with other conventional therapies, continuous intra-arterial calcium gluconate infusion therapy proved to be a safe, rapid, simple, portable, and effective method for treating hydrofluoric acid dermal burns.

Application of microautologous fat transplantation in the correction of sunken upper eyelid.

Background: Although fat grafting has been clinically applied by surgeons in esthetic and reconstructive surgery, it has widely evolved in processes such as harvesting, processing, and placement of fat, using the fat-grafting procedure, which dates back over 100 years. Surgeons frequently use fat grafting to recontour, augment, or fill soft-tissue defects, facial wrinkles, or skin problems such as depressions or scars. However, fat grafting has not been thoroughly understood and has not been conclusively standardized to ensure superior clinical results. Methods: This study was intended to determine the role of microautologous fat transplantation (MAFT) under evidence-based medicine, particularly in accurate delivery of small fat parcels. The research method involved the conceptualization of MAFT and the development of an innovative surgical instrument for fat placement. Clinically, 168 patients with sunken upper eyelids with multiple folds underwent this procedure. Results: The major findings suggested that MAFT exhibits promising clinical results and offers a superior guideline for fat placement. Details of the technique and theoretical implications are also discussed. Conclusions: The therapeutic effects of MAFT and the long-term clinical results of patients with sunken upper eyelids with multiple folds indicated satisfactory outcomes. Based on the results, MAFT offers an alternative option to surgeons for performing fat grafting and provides a more favorable option for the benefit and welfare of patients by reducing the potential complications.

Total upper lip reconstruction with a free temporal scalp flap: long-term follow-up.

In men, reconstruction of large full‐thickness defects of the upper lip requires both an inner layer to replace the mucosal lining and an outer hair‐bearing layer.

Aesthetic Analysis of the Ideal Female Leg

Abstract. The aesthetics of the attractive leg are dependent on three principle factors: length, circumference, and shape. Advances in surgical techniques and instrumentation have the ability to predict an aesthetic result in contouring the leg. However, because of patient variability and differing opinions of the surgeon, the leg aesthetics criteria and thus surgical goals have not been clearly defined. We performed an evaluation of Taiwan Chinese female leg aesthetics by using two study groups. Popular fashion models were evaluated and compared with our attractive female population. We noticed subjectively that there are similar leg shapes in both groups. Criteria that contribute to the aesthetics of the attractive legs can be used as guides for doctors and patients to achieve a more aesthetic and predictable leg contour.

Reconstruction of the upper leg and knee with a reversed flow saphenous island flap based on the medial inferior genicular artery

Soft-tissue defects around the knees and below-the-knee amputation stumps are difficult to reconstruct. We present an option for reconstruction of these defects. Reversed flow saphenous island flaps, based on the medial inferior genicular artery, were successfully transferred in 6 patients. All wounds healed well postoperatively. The donor defect can be closed directly when the width is less than 7 cm. This is a thin and reliable fasciocutaneous flap that is useful in covering defects around the knee joint, popliteal fossa, upper half of the leg, and below-the-knee amputation stump.

Aquacel Ag with Vaseline gauze in the management of toxic epidermal necrolysis (TEN).

UNLABELLED Toxic epidermal necrolysis (TEN) is a rare condition with potentially high mortality and involves severe exfoliative disease of the skin and mucous membranes induced by drugs. The reported fatality of TEN varies widely from 20% to 60%. The technique for TEN wound coverage described in this article involves the use of various dressings. PATIENTS AND METHODS Nine women with histologically confirmed TEN (>30% total body surface area, TBSA) were treated at our burn intensive care unit. All patients received hydrotherapy and wounds were covered with Aquacel Ag and Vaseline gauzes onlay. Following this, elastic cotton bandage was wrapped around the dressing. The dressing was changed and the wound evaluated twice a week. Efficacy was established by the wound achieving>or=95% re-epithelialisation of the study area. RESULTS The mean age was 60.1 years (range from 7 to 88 years). The percentage of body surface area affected by epidermal slough ranged from 30% to 85% TBSA, with a mean of 51%. One patient expired due to severe sepsis on day 3. Eight patients achieved over 95% wound healing. All wounds healed well without the need for skin grafting. However, two of them expired on day 14 and day 20 because of pneumonia and retention of carbon dioxide, respectively. The average duration to achieve 95% wound healing was 10.4 days in eight cases (range from 7 to 14 days). No adverse reactions were noted. CONCLUSION Aquacel Ag dressing can be easily removed during hydrotherapy. The wound pain is reduced. By changing the dressing just twice a week, we were able to evaluate the wound directly, decrease the odour and increase the quality of life of the patients. In addition, lower frequency of dressing changes decreases the manpower requirements and is cost effective. Use of Aquacel Ag with Vaseline gauze is a good alternative for the management of TEN wounds.
