[Primary excision of third degree burns].

Fresh third-degree burns with a diameter up to that of a hand should be excised primarily and the wound edges closed under tension. Fasciocutaneous flaps can be designed for wound closure especially on the extremitites. This treatment requires half the time of skin grafting. Since patients with huge burn areas often react with hypertrophic scarring for years, a simple reduction of the areas by wide excision and closure under tension appears to be the method of first choice. In contrast to scar tissue healthy skin has a natural ability to stretch when wound margins are closed under maximal tension. The efficacy of possibilities is proven by the many favourable results.

[Serial excision of large surface burn scars].

Serial excisions of large defined burn scars often improve the aesthetic appearance as well as reduce subjective complaints such as itching and sensory disturbance. The natural elasticity of undamaged skin allows stepwise excision of areas up to the size of a hand. Ideally, a linear scar the length of the original scar area results. Shrinkage, contour and pigment deficiencies, often seen after skin grafting, are not a problem.

[Plastic correction of thoracic wall burns with reference to the female breast].

Neck and shoulder contractures, large scars of the thoracic wall and breast defects require plastic surgery. If possible, local flaps are the best solution for contractures, eventually enlarged by skin expanders. Full thickness skin grafts, Z-plasties and simple excisions with primary wound closure are alternative methods. For breast reconstruction early skin grafts or secondary local flaps are used. Myocutaneous flaps from the latissimus dorsi or rectus abdominis are seldom indicated.

[Plastic surgery reconstruction following irradiation].

Radiation damage after combined tumor therapy may involve skin, subcutaneous tissue, nerves, bones and viscera. Ulceration and subsequent infection can result in life-threatening conditions. Early reconstructive procedures restore function, prevent further damage and alleviate pain. Plastic surgery has developed special fasciocutaneous and musculocutaneous flaps for each region.

[Primary management of fresh bite injuries of the face].

The danger of dog bites is often exaggerated. The reason for this is a gram negative bacterium Pasteurella multocida, which causes a serious infection within 12 h. Among 143 dog bites we saw only two of these infections. The bacterial swabs from the mouths of 20 dogs revealed E. coli in 43%, Streptococci in 33%, Proteus in 30%, Staph. epidermidis in 27% and Enterococci in 25%. Since the blood supply of the face is much more superior to that for instance of the legs, infections are rare and primary closure of wounds of dog and human bites is recommended. Additional drainage, hospitalisation and local and systemic antibiotics are possible. Open wound therapy in the face can be called obsolete.

[Surgical therapeutic possibilities in extensive chest wall and rib metastases].

87 extensive tumors of the chest wall were resected in an 8 year period. The defects including subtotal sternectomies and segment resections up to 7 ribs were reconstructed with musculocutaneous flaps without any osteoplasty or implants. The latissimus dorsi flap closes pleural defects safely. The innervated muscle stabilizes the chest wall. The rectus abdominis flap fits defects of greater volume but the blood supply is less reliable. The use of pectoralis major or free microsurgical tissue transfer may be indicated in absence of any other possibility.

[Retrograde or orthograde anatomic perfusion of the free forearm flap?].

The free forearm flap is ideal for vascularized tissue transfer because of its large vessels and multiple nerve supply. In the case presented a distally based forearm flap on a long vascular pedicle was employed relying on a reversed blood flow. Unfortunately the reversed venous flow did not develop and therefore in order to provide a venous drainage an autologous vein graft was used.

[Buruli ulcer--necrotizing infection of the hand of a plastic surgeon].

The Buruli ulcer is caused by mycobacterium ulcerans. The clinical features of this atypical mycobacteriosis are similar to tuberculosis. Differentiation is only possible by microbiological investigation. In cases of chronic soft tissue infections mycobacteriosis must be taken into consideration. Since microbiological differentiation needs 8-12 weeks and chemotherapy is not effective, early and wide surgical excision is the treatment of choice.

[Treatment of funnel chest with RTV-silicone implants].

The funnel chest is no physiological but a psychological problem for the majority of patients. Only 5% suffer from pathological parameters which require a surgical elevation of the funnel. After these rather complicated operations, however, only 60-80% are followed by good long-term results. The described RTV-silicone implant is formed preoperatively directly in the funnel and appears to be a simple safe and lasting alternative for most patients with a funnel chest.
