ABSTRACT

Abstract Purpose To evaluate whether silicone foam implants have a different evolution pattern compared to conventional texture implants. Methods Fifty-eight female patients underwent surgery. They were divided into two groups (silicone foam - Lifesil® - and microtexturized silicone - Lifesil®). The evolution was analyzed in postoperative consultations, with physical examination, photographic documentation and filling in a satisfaction questionnaire, in the postoperative period of one month, four months, one year and then annually, up to a maximum of 3 years of follow-up. Results There were no statistically significant differences in presence of rippling, stretch marks, breast ptosis, capsular contracture and quality of scars. There was a higher rate of patients who were very satisfied with the outcome 360 days after surgery in the group receiving silicone foam implants (p = 0.036). Conclusion In short time, silicone foam envelope implants proved to be as reliable as textured silicone envelope implants, making them an option for augmentation mammoplasty.

ABSTRACT

INTRODUÇÃO: A proeminência dos pavilhões auriculares é a forma mais comum de deformidade desta estrutura, afetando em torno de 5% da população. A maioria dos trabalhos acerca da cirurgia de otoplastia apresenta avaliações subjetivas, não permitindo apreciar acuradamente os resultados no pós-operatório, bem como dificultando a comparação entre técnicas. Propõe-se o desenvolvimento e aplicação de protocolo específico para avaliação dos resultados. MÉTODO: Avaliação prospectiva pelo período de um ano de pacientes submetidos à otoplastia bilateral utilizando técnica baseada em modelagem cartilaginosa com suturas, utilizando medidas da distância hélice-mastoide em pontos padronizados. RESULTADOS: Foram operados 23 pacientes com idade média de 17,8 anos. A incidência de reoperação foi de 21,7% dos pacientes ou 10,7% das orelhas. Houve perda de cerca de 45% da correção obtida no ponto superior e 35% nos pontos médio e inferior nos pacientes não reoperados. CONCLUSÕES: O protocolo foi de fácil utilização e permitiu a avaliação objetiva tanto da deformidade no pré-operatório quanto dos resultados cirúrgicos. A técnica utilizada produziu resultados considerados adequados e comparáveis aos da literatura.


INTRODUCTION: Prominence is the most common deformity of the ear, affecting about 5% of the population. Most reports on otoplasty describe subjective evaluations, and do not provide accurate postoperative assessment or a comparison between techniques. We propose the development and implementation of a specific protocol to evaluate results. METHOD: A prospective evaluation for a period of one year in patients who underwent bilateral otoplasty was performed, using a technique based on modeling of the cartilage with sutures, and helix-to-mastoid distance measurements at standardized points. RESULTS: A total of 23 patients with an average age of 17.8 years underwent surgery. Reoperation was performed in 21.7% of the patients or 10.7% of the ears. Nearly 45% of the correction obtained at the upper point and 35% at the middle and lower points were lost in patients who did not undergo reoperation. CONCLUSIONS: The protocol was easily used and allowed objective evaluation of the preoperative deformity and surgical results. This technique produced results considered adequate and comparable to the literature.

ABSTRACT

PURPOSE : To evaluate the effect of different energies and stacking in skin shrinkage. METHODS : Three decreasing settings of a fractional CO2 laser were applied to the abdomen of Twenty five Wistar rats divided into three groups. Group I (n=5) was histologically evaluated for microthermal zones dimensions. Groups II and III (n=10 each) were macroscopic evaluated with freeware ImageJ for area contraction immediately and after 30 and 60 days. RESULTS : No statistical significance was found within microthermal zone histological dimensions (Group I) in all settings studied. (Ablation depth: 76.90 to 97.18µm; Coagulation depth: 186.01 to 219.84 µm). In Group II, macroscopic evaluation showed that all settings cause significant immediate skin contraction. The highest setting cause significant more intense tightening effect initially, contracting skin area from 258.65 to 179.09 mm2. The same pattern was observed in Group III. At 30 and 60 days, the lowest setting significantly sustained contraction. CONCLUSION : Lower fractional CO2 laser energies associated to pulse stacking could cause consistent and long lasting tissue contraction in rats.

ABSTRACT

Introdução: As malformações vasculares congênitas do tipo capilar têm seus melhores resultados até o momento com o laser de corante. Nós associamos, em um único equipamento, o laser ND:Yag 1064 nm de pulso longo e a luz intensa pulsada, para o tratamento de lesões superficiais e profundas. Método: Dezessete pacientes foram tratados com a associação descrita em regime ambulatorial, com anestesia tópica, apenas em intervalos mensais, pelo mesmo cirurgião. O equipamento utilizado foi a plataforma Synchro (DEKA), com a ponteira de 4 mm de diâmetro e fluência de 110 J/cm2 para o laser ND:Yag 1064nm. Para a luz intensa pulsada foi utilizado um filtro de corte de 550 nm, a ponteira de 46 x 10 mm e 21 J/cm2 de fluência, divididos em dois disparos. Os resultados foram avaliados clinicamente e por meio de fotografias, em conjunto com os pacientes. Resultados: Dentre os dezessete pacientes tratados, quatro resultados foram considerados excelentes, nove, bons, quatro, regulares e nenhum insuficiente. Conclusão: O tratamento pode ser realizado adequadamente com anestesia tópica em regime ambulatorial. A associação das duas tecnologias possibilitou a obtenção de resultados satisfatórios e, provavelmente, é mais uma técnica no tratamento destas lesões.


Introduction: Congenital vascular malformations up to know, have their best results with dye laser. We associate, in single equipment, long pulse Nd:Yag 1064 nm laser and intense pulsed light, for simultaneous treatment of the superficial and deep lesions. Methods: Seventeen patients were treated with the association described in an office basis with topical anesthesia only at monthly intervals by the same surgeon. The equipment utilized was the Synchro Platform (DEKA) with a 4 mm diameter spot size and fluency of 110 J/cm2 for the ND:Yag 1064 nm laser. For the intense pulsed light was utilized a 550 nm cutoff filter with a 46 x 10 mm spot size and 21 J/cm2 as fluency, divided in two shots. Results were evaluated through clinical and photographical analysis together with the patient. Results: Among the seventeen patients treated, four results were considered excellent, nine, good,four, regular and none insufficient. Conclusion: The treatment can adequately be done in an office basis with topical anesthesia. Association of the two different technologies got a satisfactory result and it is probably one more technique for treating such lesions.
