Tatica na abordagem umbilical em abdominoplastias / Tactics in the umbilical approach in abdominoplasties

Os autores estudaram 58 pacientes do sexo feminino submetidas a abdominoplastia, desde 1985, utilizando tatica cirurgica que, obedecendo a criterios simples, permitiu a obtencao de umbigos com caracteristicas muito proximas as do umbigo nao operado.

Retracao primaria dos enxertos de pele / Primary retraction in skin grafting

Os autores estudaram a retracao primaria dos enxertos de pele relacionando-a com a espessura dos mesmos e a distencao da area doadora, apos a excisao dos enxertos, relacionando-a com a espessura da derme residual. Foram estudados dez areas doadoras e os respectivos enxertos. A espessura media dos enxertos estudados foi 318,0 micra que corresponde a 20,0 por cento da pele doadora. A retracao primaria desses enxertos foi 17,6 por cento da area doadora. Os autores compararam os resultados com aqueles obtidos por Davis e Ketowsk, salientando as diferencas entre os metodos utilizados nos dois trabalhos. A espessura media da derme residual das areas doadoras logo apos a excisao dos enxertos foi 1.287,0 micra que corresponde a 85,2 por cento da espessura media da derme reticular da pele doadora. A distencao da area doadora apos a retirada do enxerto foi de 2,1 por cento da original.

[Primary retraction in skin grafting]. / Retração primária dos enxertos de pele.

In ten patients a study of skin grafts and of the changes that occurred in the donor area was carried out: the primary retraction of the grafts in relation to their thickness was determined as well as the distension of the donor area of the graft after the excision of the same and comparison of it's thickness with that of the residual skin. The average thickness of the grafts was 318.0 micra, which corresponded to 20% of the donor skin. The primary retraction was 17.6%. The mean thickness of the residual skin at the donor area was 1,287.0 micra or 85.2% of the mean thickness of the reticular derma: the distension of the donor skin area after the removal of the graft corresponded to 2.1% of the original size.

The authors review 58 female patients, submitted to abdominoplasty. They utilized a technical approach that permitted to obtain umbilical scars similar to the normal ones.

Correction of microtia with construction of the tragus using a chondrocutaneous flap.

For microtia correction we have been inserting a cartilage framework and reconstructing the tragus at the first operation in one stage, using part of the microtic ear. This procedure is started with transposition of the lower two-thirds of the microtic ear to make a lobule. The upper third of the microtic ear is elevated as a chondrocutaneous flap which is then transposed downwards to the conchal cavity to make a tragus. The cartilage of the chondrocutaneous flap is anchored, using a bolster to pull it back and outwards. Using this technique, we have reconstructed 34 microtic ears. Adequate positioning of the auricle and tragus has been achieved and a natural auricle obtained even when observed from a frontal oblique direction.
