Enxerto de Gordura Prévio e Transplante pela Técnica FUE em Cicatrizes do Couro Cabeludo: Atualização / Previous fat grafting and hair transplantation using the FUE technique on scalp scars: Update

Foi realizada uma revisão de literatura narrativa, sobre a associação de enxerto de gordura e transplante de cabelos com a técnica FUE (Follicular Unit Extraction) em cicatrizes do couro cabeludo. Os dados foram coletados a partir de estudos encontrados nas bases Medline, Lilacs e IBECS. Foram citados registros bibliográficos de vários autores que pesquisaram as células mesenquimais do tecido gorduroso, com descrição das técnicas utilizadas. A conclusão foi de que a técnica de transplante capilar em duas etapas, com transplante prévio de gordura é eficaz, segundo os artigos revisados.

We developed a narrative literature review on the association of fat grafting and hair transplantation using the Follicular Unit Extraction (FUE) technique in scalp scars. Data were collected from studies found in Medline, Lilacs, and IBECS databases. Bibliographical records of several authors who researched mesenchymal cells in adipose tissue were cited, describing the techniques used. The conclusion was that the two-stage hair transplantation technique, with previous fat transplantation, is effective, according to the reviewed articles.

Autologous fibroblast culture in the repair of aging skin.

BACKGROUND: Human cell cultures are being developed to replace various body tissues. OBJECTIVE: To assess the safety and efficacy of dermal regeneration with the injection of young autologous fibroblasts obtained from culture containing serum from patients themselves. MATERIALS AND METHODS: Dermal tissue from the groin of five patients was cultivated in M199 medium supplemented with 10% human serum. Four population doublings were obtained. The fibroblasts were injected intradermally into forehead wrinkles and periorbital and paranasal areas. RESULT: At the fourth population doubling, a mean of 3.85 × 10(6) cells/mL was obtained; viability was 98%. Sixty days after completing treatment, with four injections given at 15-day intervals, periorbital tonicity had improved significantly, although the quantity of fibroblasts used resulted in little improvement to surface lines and no improvement at all in deeper wrinkles. After 6 months, no further changes were found beyond the initial results obtained. CONCLUSION: Injection of skin fibroblasts cultivated in medium supplemented with human serum is a viable technique and provokes no side effects. Four injections given at 15-day intervals containing a total of 6.4 × 10(6) fibroblasts/mL resulted in significant improvement in periorbital skin flaccidity. Further studies should be conducted with larger sample sizes.

Técnica do anel para correção de cicatrizes inestéticas periauriculares / Ring technique fot the correction of unaesthetic periauricular scars

As cicatrizes inestéticas alargadas ou hipertróficas periauriculares podem ser decorrentes da tensão sobre a sutura das incisões da ritidoplastia. Em estudo retrospectivo de cinco anos, 10 pacientes do sexo feminino portadoras de cicatrizes inestéticas foram tratadas com a técnica do anel periauricular. Utilizou-se o fio de politetrafluoretileno em seis casos e o de mononylon 2-0 duplo em quatro casos, introduzidos com agulha de fáscia lata sem bisel. Após a exerese da cicatriz, as bordas foram aproximadas, e o anel amarrado e fixado na fáscia do músculo temporal. O resultado foi satisfatório. Em dois casos os fios foram removidos sem alteração do resultado estético final das cicatrizes.
