    ABSTRACT: We report the case of a 47-year-old woman with a large keloid scar on the sternum who was submitted to a simultaneous scar removal with bilateral breast-reduction mammaplasty. Breast reduction was performed to reduce local skin tension and to provide a skin flap for the full reconstruction of the scar-removal site. The association of these surgical procedures stands as a viable alternative for the reconstruction of the sternum region, producing less keloid scarring.

    ABSTRACT: Cutaneous injuries of the inferior third of the leg and dorsum of the foot represent a great challenge for plastic surgeons. The poor vascularization and subsequent poor healing encountered in these regions demand detailed knowledge of the local anatomy to select the best surgical alternative for each patient. In patients in whom local or free muscular flaps are not suitable, the fasciocutaneous flaps seem to be a good alternative. The distal pedicled fasciocutaneous flap of the calf was used to cover skin defects of the leg and foot in 22 patients. In 4 patients the authors designed an island flap to prevent a large defect in the donor area and to decrease the time of hospitalization and recovery of the patient. In a severe defect, the flap was used as a cross-leg flap. The results were satisfactory because the flap provided stable coverage for different defects with few complications. The island flap is a good option for achieving a better aesthetic result and can be used in select patients.

    ABSTRACT: We compared autologous bicortical ilial and cranial bone grafts onlaid to the facial skeleton in 60 adult New Zealand rabbits to evaluate the initial phase of incorporation of these grafts. The animals were distributed in two equal groups in which either cranial or iliac grafts were harvested and fixated, devoid of their periosteum, in direct contact with the nasal bone with micro screws. Each of these two groups were then subdivided into three groups, which corresponded to the three times the animals were killed: 18 days, 30 days, and 60 days. The grafts were measured in their linear dimensions and weighed before fixation and after harvesting when the animals were killed. Undecalcified histological sections were prepared, and histomorphometric parameters of bone formation (bone volume, osteoid volume, surface thickness, and osteoblastic surface) and resorption (osteoclastic surface and eroded surface) were measured. The results confirmed those of previous studies in that cortical grafts maintained their volumes to a greater extent than their cancellous counterparts indicating that the remodeling process may be uncoupled in the transplanted iliac grafts. It is postulated that the significant decrease in mechanical stimulus that the cancellous grafts undergo determines this imbalance in the remodeling activity, which results in greater bone resorption than formation and thus decreased volume.

    ABSTRACT: The importance of facial trauma comes from the possibility of leaving serious functional and aesthetic consequences. Since 1990 patients with facial fractures were treated at the Emergency Ward of the Hospital das Clinicas of the Medical Faculty of São Paulo by plastic surgeons. In 24 months, 130 patients with facial fractures were treated there. The main causative factors were motor vehicle accidents (51%) and the main bone fracture was that of mandible (46%). A correlation between the kind of trauma and the kind of fracture is made.

    ABSTRACT: The authors present thirty-four patients with microgenia operated on by advancement genioplasty. The indications and advantages of this method in improving the facial profile are reviewed and compared with other surgical possibilities described in the literature.

    ABSTRACT: The lateral calcaneal artery flap is an axial flap which comprises also the saphenous vein and the sural nerve. Its use has been reported for coverage of skin loss of the malleolus and calcaneal area. The donor area should be closed by a split thickness skin graft. In the present report, eight patients who had skin loss on the foot were submitted to reconstruction with the lateral calcaneal flap. In seven there were island flaps and in one a bridge of skin similar to that described by Grabb and Argenta. The etiology was trauma in five patients and decubitus ulcer in three. The results were good. The flap was adequate for the cover on the posterior foot area even after submitted to the strain of normal walking. The advantages were simpler technique and consistency of the anatomical landmarks.

    ABSTRACT: The clinical features of the toxic shock syndrome are well established. It is rapidly developing disease and may be lethal if not recognized and treated in time. Once the syndrome was associated with the use of tampon by menstruating women. Recently this syndrome has been reported as due to Staphylococcus aureus infection. A severe case of toxic shock syndrome in a 18-years-old patient after reduction mammoplasty is reported, and the importance of an early diagnosis is emphasized.
