The management of complicated charcoal contact burns involving deep tissues.

This report describes the management of a charcoal burn involving deep tissues at different anatomic sites. The closure of burn wounds should be considered as a functional and cosmetic outcome whenever possible. Our aim should be to get the soft tissue of the early burned wound closed. A satisfactory result can be achieved if both the functional anatomy and the aesthetic outcome can be kept in mind while planning the management.

Split calvarial bone graft for chemical burn-associated nasal augmentation.

The nose is the central part of the face, and constitutes the most prominent projection in facial geometry. This report presents five cases that sustained a chemical burn injury with associated facial mutilation resulting from contact with strong acids. The chemical burn affected the nasal architecture after inflicting a burn injury to the face. Applying bone deriving from a split skull procedure for the nasal projection restoration and the augmentation of the dorsal nose is a feasible undertaking, and the overall result appears satisfactory. A retrospective survey of cases admitted to our clinic from January 1999 to December 2001, inclusively was undertaken and is described below. Split calvarial bone graft procedure for the nasal tip projection reconstruction was performed for five patients, all of whom had sustained chemical burns following assault by strong acid. The disfiguration of the nasal anatomical structure was due to healing from deep burn wounds. The tip became blunt and less protruberant following the arising of cicatricial tightness of the surrounding tissue. Strength and resistance to scar contraction are the first considerations for such implantation when attempting to correct the nasal tip projection. The five female patients sustained a severe chemical burn which involved a surface area ranging from 25 to 60% of total body surface area. The facial mutilation was noted simultaneously with the determination of the extent of the burning injury. A severe burn scar is the typical sequel following a deep chemical burn. Nasal tip projection was restored and a nasal dorsum augmentation procedure with a split calvarial bone graft under an "open" method was used. This particular surgical procedure was able to be used in order to improve the nasal tip projection and resist surrounding scar contracture. The three-dimensional surface structure of the face became more prominent subsequent to the administration of this procedure.

Use of a versatile transpositional flap in the surgical treatment of axillary hidradenitis suppurativa.

Axillary hidradenitis suppurativa is a chronic recurrent disorder characterized by abscessing inflammation, fistulating sinus tracts, and scarring. This is not only a medical disease, but also a complicated problem necessitating surgical intervention. While various management strategies have been reported, the results are frequently unsatisfactory. Primary closure of the defect after radical excision is often impossible and results in poor wound healing. Skin graft on the soft tissue defect often results in obvious scar contracture and limitation of movement. Local muscle flap can fill in the defect but the range of adduction of the arm will be limited by its muscle bulk. Free flap transfer is a choice of management but this technique calls for a trained team, laborious execution, expensive instruments and plenty of time. We describe the use of transpositional fasciocutaneous flap, which can provide a reliable flap of variable size of skin and soft tissue coverage with good elastic properties. The technique is easily adapted to the reconstruction of resultant defects. This technique was used to transfer 8 transpositional fasciocutaneous flaps in 7 patients for the closure of axillary defects resulting from radical excision of chronic hidradenitis suppurativa. No flap complication or disease recurrence was observed during 2 years of follow-up. The technique had satisfactory esthetic and functional results as well as low donor site morbidity.

Free medial sural artery perforator flap for resurfacing distal limb defects.

BACKGROUND: The need for thin flap coverage has increased, especially for contouring or covering shallow defects of distal limbs. The free medial sural artery perforator flap harvested from the medial aspect of the upper calf can be useful for this purpose. METHODS: Between January 2002 and February 2003, we used the free medial sural artery perforator flap for distal limb reconstruction in 11 clinical cases, including four hands and seven feet. This perforator flap is based on the proximal major perforator of the medial sural artery, which can be identified along the axis of the medial sural artery and usually emerges in an area between 6 and 10 cm from the popliteal crease and approximately 5 cm from the posterior midline of the leg. RESULTS: Most of the flaps were safely raised with a single perforator. One flap developed venous congestion during the postoperative course and finally underwent total necrosis. CONCLUSION: The main advantage of the medial sural artery perforator flap is that it only requires cutaneous tissue to achieve better accuracy in reconstructive site, and it preserves the medial gastrocnemius muscle and motor nerve to minimize donor-site morbidity. However, the tedious process of intramuscular retrograde dissection of the perforator and the unsightly scar of the donor region are the major concerns.
