RESUMEN

INTRODUCTION: Myomodulation is a technique aimed at enhancing the dynamics of muscle contraction and relaxation through methods like hyaluronic acid (HA) injection. Achieving optimal outcomes depends on the precise placement of the injected product within the targeted anatomical plane. This is particularly important in the forehead, an area with elevated vascular risk. The selected treatment techniques must ensure both efficacy and safety. This study aims to assess the anatomical precision of HA injections in the forehead using different techniques and devices. METHODS: Four fresh frozen specimens were injected with HA by five experienced board-certified plastic surgeons using three different techniques/devices: (1) a 50 mm, 22G microcannula; (2) a 13 mm, 27G needle with the bevel down at a 45-degree angle; and (3) the same needle positioned at a 90-degree angle. Ultrasound analysis was used to evaluate the precision of each approach. RESULTS: Both the cannula technique and the needle technique with the bevel down at a 45-degree angle consistently delivered the filler to the supraperiosteal layer in 100% of cases without spreading. However, the 90-degree needle technique, despite correct placement on the periosteum, resulted in filler dispersion across multiple layers. CONCLUSION: The accuracy of filler placement in the forehead is influenced by the choice of device and its angulation. It is recommended to use a cannula with the entry point at the frontalis crest or a needle angled at 45 degrees to the skin. The use of a needle at a 90-degree angle should be avoided to ensure precise placement and avoid filler migration.

RESUMEN

INTRODUCTION: Hand aging is a prevalent concern characterized by the atrophy of local soft tissues and increased visibility of vessels and tendons. Hyaluronic acid (HA) and calcium hydroxyapatite (CaHA) are well-established treatments for addressing this issue. While hybrid filler containing HA and CaHA has been proposed for facial rejuvenation, studies investigating its efficacy for hand rejuvenation are lacking. OBJECTIVE: This study aims to assess the safety and efficacy of a premixed hybrid filler containing calcium hydroxyapatite (CaHA) and hyaluronic acid (HA) for hand rejuvenation. METHODS: A prospective, double-blind, controlled trial was conducted. The control arm (CA) received conventional subdermal treatment with CaHA at a 1:1 dilution. The intervention arm (IA) underwent hybrid treatment, consisting of CaHA at a 1:1 dilution combined with 1 ml of low-density HA. Evaluation was performed subjectively using the Global Aesthetic Improvement Scale (GAIS) and the Manchester Hand Grading System (MHGS), and objectively using cutometry, corneometry, and ultrasound. RESULTS: Both the CA and the IA exhibited high rates of patient satisfaction and satisfaction as assessed by blinded evaluators. Although numerical superiority was observed in the IA, no statistical difference was found between the two groups. Significant improvements in hydration, elasticity, and skin thickness were observed in both arms, with no discernible difference between them. Greater ultrasound echogenicity was noted in the IA, which, as indicated by existing literature, may suggest enhanced biostimulation. No adverse effects were reported in either arm. CONCLUSION: Premixed filler containing HA and CaHA for hand rejuvenation appears to be a safe and effective approach.

RESUMEN

Introduction: Anatomy is one of the foundations in medicine, and choosing a practical and dynamic teaching method is essential for better retention of your learning. The objective is to use facial anatomy applied to live models as an innovative teaching strategy and to evaluate the experience of the learning experience of students assigned to the method. Method: The work analyzes the experience with body painting of 51 students from Instituto Boggio assigned this method (or instructed to use this method) during their classes. Different planes and anatomical structures were represented on live models' faces to simulate and teach the main injectable cosmetic procedures; syringes, needles, cannulas, and ultrasound gel stained with food inks were used. Overlapping latex layers were used for the anatomical study of the temple, middle third of the face, and nose, allowing the reproduction of fillers and biostimulators in these regions. The main muscle groups were represented for the discussion of high-precision botulinum toxin. After the entire demonstration, the students answered a questionnaire via "Google Forms" evaluating the methodology used. Results: According to the answers to the questionnaires, most students considered body painting an innovative methodology that contributed to learning anatomical content and satisfactorily illustrating the demonstrated cosmetic procedures. Conclusion: Practical learning through live models makes this new teaching method something innovative and unique that, in an enjoyable way, enables the study of anatomy and appropriately trains clinical skills.

Camadas de látex sobrepostas foram utilizadas para estudo anatômico da têmpora, terço médio da face e nariz, possibilitando a reprodução do uso de preenchedores e bioestimuladores nestas regiões. Os principais grupamentos musculares foram representados para discussão sobre toxina botulínica de alta precisão. Após toda a demonstração, os alunos responderam a um questionário via "Formulários Google" avaliando a metodologia utilizada. Resultados: De acordo com as respostas dos questionários, a maioria dos alunos considerou a pintura corporal como uma metodologia inovadora e que contribui no aprendizado do conteúdo anatômico, bem como ilustra satisfatoriamente os procedimentos cosmiátricos demonstrados. Conclusão: A aprendizagem prática por meio dos modelos vivos faz deste novo método de ensino algo inovador e único que, de maneira lúdica, possibilita o estudo da anatomia e o treinamento de habilidades clínicas adequadamente.

RESUMEN

INTRODUCTION: The anatomical complexity of the temporal region makes it so treatments with fill-ins are challenging due to high vascular risk. Techniques which provide safer procedures must be encouraged. GOAL: Suggest access to the temple through the inferolateral orbital region as a means for safer temporal fill-ins. METHODS: The fanning technique was plotted out not only via the conventional access (pretragal) but via the proposed one as well. The superficial temporal artery (STA) was mapped with ultrasound. The angles for each of the five retroinjection vectors were calculated in relation to STA and their mean was extracted. The longitudinality of the vector in regard to the vessel was considered the least safe factor. RESULTS: The mean injection angle towards the artery was a 35-degree angle for the conventional access technique and a 73-degree angle for the inferior-lateral orbital access technique (p < 0.05). The more a degree is tangential to the vessel, the higher the chances for inadvertent puncture due to small technical issues. The safety of the procedure through the inferolateral orbital access is corroborated with blind ultrasound imaging done in real-time by radiologists. CONCLUSION: The suggested access is shown to be comparably safer from a vascular perspective than the conventional pretragal access.

RESUMEN

A percepção da beleza é ainda algo pouco compreendida, apesar de francamente notável. Pessoas consideradas belas notadamente tem melhor autoestima e um melhor desempenho em suas relações interpessoais. A procura por tratamentos cosmiátricos está em franca ascensão e o crescimento entre os homens é ainda maior. A perfeita compreensão das diferenças entre os atributos masculinizantes e feminilizantes em uma face deve ser encorajado, a fim de obter melhores resultados estéticos e a prevenção de estigmas de tratamento. Nesta revisão, será abordada cada região facial, pormenorizando os padrões de beleza de cada gênero, norteando os detalhes do tratamento.

The beauty perception is still poorly understood, though downright remarkable. People considered beautiful notably have better self-esteem and perform better in their interpersonal relationships. Demand for cosmetic treatments is on the rise and growth among men is even higher. Perfect understanding of the differences between masculinizing and feminizing attributes on a face should be encouraged in order to achieve better aesthetic results and the prevention of treatment stigmas. This review will cover each facial region, detailing the beauty standards of each gender, guiding the details of treatment.

RESUMEN

A assimetria mamária é um diagnóstico prevalente com diversas modalidades cirúrgicas para seu tratamento. O correto diagnóstico, levando-se em conta os sistemas de classificação existentes é imperativo para que os melhores resultados sejam alcançados. Através de revisão da literatura foram levantadas as principais e mais aceitas propostas de classificação e tratamento das assimetrias mamárias. Estas classificações disponíveis datam da década de 60 e 70 e carecem de atualização para o contexto clínico atual. Após ampla revisão da literatura foi proposta uma classificação mais simplificada e reprodutível, levando-se em conta as assimetrias mais frequentes nos consultórios de cirurgia plástica estética, com seus respectivos guias de tratamento. Cinco grupos foram criados: 1 - mamas hipotróficas com assimetria de volume; 2 - hipotrofia com assimetria de volume e contorno; 3 - mamas normotróficas, ptóticas e sem desejo de aumento do volume; 4 - mamas normotróficas, ptóticas e com desejo de aumento do volume final; 5 - mamas assimétricas e hipertróficas. Baseado nos achados clínicos, foi criado um algoritmo de tratamento para cada subtipo de assimetria, incluindo neste arsenal, próteses mamárias de volumes diferentes, mastopexias, mamoplastia redutoras, além da lipoenxertia. Importante ressaltar que a assimetria mamária é a regra e não a exceção, entretanto, é motivo de insatisfação das pacientes e um desafio para o cirurgião plástico.

Breast asymmetry is a prevalent diagnosis that has several surgical modalities for its treatment. The correct diagnosis, taking into account the existing classification systems, is imperative for achieving the best results. The leading and most accepted proposals for the classification and treatment of breast asymmetries were raised through the literature review. These available classifications date from the 60s and 70s and need to be updated to the current clinical context. A more simplified and reproducible classification was proposed after a comprehensive literature review, considering the most frequent asymmetries in aesthetic plastic surgery offices, with their respective treatment guides. Five groups were created: 1 - hypotrophic breasts with volume asymmetry; 2 - hypotrophy with volume and contour asymmetry; 3 - normotrophic, ptotic breasts and with no desire to increase the volume; 4 - normotrophic, ptotic breasts and with a desire to increase the final volume; 5 - asymmetric and hypertrophic breasts. Based on the clinical findings, a treatment algorithm was created for each subtype of asymmetry, including in this arsenal, breast implants of different volumes, mastopexies, reduction mammoplasty, and fat grafting. It is important to emphasize that breast asymmetry is the rule and not the exception, therefore, it is a reason for patient dissatisfaction and a challenge for the plastic surgeon.

RESUMEN

INTRODUÇÃO: As cirurgias bariátricas são cada vez mais frequentes no tratamento dos pacientes portadores de obesidade mórbida. A grande perda ponderal decorrente desses procedimentos causa excesso de pele e de tecido subcutâneo em todo o corpo, especialmente na região abdominal. O objetivo deste trabalho é apresentar a técnica de abdominoplastia vertical como alternativa para a ressecção do excesso de pele nesses pacientes. MÉTODO: Foram avaliados, retrospectivamente, os prontuários de 40 pacientes submetidos ao procedimento entre 2004 e 2009. O grau de satisfação dos pacientes foi avaliado através de escala subjetiva, com notas variando de 0 a 10. RESULTADOS: Vinte e cinco por cento dos pacientes apresentaram pequenas complicações, sendo 3 seromas, 3 pequenas deiscências e 5 cicatrizes hipertróficas, todas tratadas ambulatorialmente. Dois terços dos pacientes relataram alto grau de satisfação, considerando seus resultados bons (notas 7 ou 8) ou ótimos (notas 9 ou 10). CONCLUSÕES: A técnica de abdominoplastia vertical aparece como uma nova opção para o tratamento do excesso de pele abdominal em pacientes ex-obesos.

BACKGROUND: Bariatric surgeries are becoming increasingly common in the treatment of morbidly obese patients. The enormous weight loss resulting from these procedures causes excessive skin and subcutaneous tissue throughout the body, especially in the abdominal region. The objective of this study was to present the technique of vertical abdominoplasty as an alternative for resection of excess skin in ex-obese patients. METHODS: We retrospectively evaluated the records of 40 patients who underwent vertical abdominoplasty between 2004 and 2009. The degree of patient satisfaction was assessed through a subjective scale, with scores ranging from 0 to 10. RESULTS: Twenty-five percent of the patients had minor complications (3 seromas, 3 minor dehiscences, and 5 hypertrophic scars), which were all treated on an outpatient basis. Sixty-seven percent of the patients reported high satisfaction and considered their results as good (grades 7 or 8) or excellent (grades 9 or 10). CONCLUSIONS: The vertical abdominoplasty technique appears to be a new option for the treatment of excess abdominal skin in ex-obese patients.
