RESUMO

El envejecimiento facial es una sinergia compleja de cambios texturales de la piel, hiper- o hipoactividad muscular, reabsorción del tejido graso y resorción ósea. El déficit de volumen resultante, la deflación y la posterior caída del tercio medio facial produce una cara menos atractiva y juvenil. Los procedimientos inyectables en región malar son cada vez más populares y solicitados por los pacientes. El conocimiento de la anatomía de la cara media es fundamental para el inyector. La comprensión de la irrigación facial puede ayudar a disminuir la exposición a la aparición de hematomas y complicaciones vasculares severas. Existen múltiples técnicas de inyección propuestas para el tercio medio, en este artículo presentamos una técnica original, simple, segura y eficaz con resultados satisfactorios y riesgo reducido


Facial aging is a complex synergy of textural skin changes, muscle hyperactivity, fat dysmorphism, bone resorption. The resulting volume deficit and deflation of the mid face produces a less attractive and youthful face. Injectable midface procedures are becoming increasingly popular and requested by patients. Knowledge of the anatomy of the midface is critical for the injector. Understanding the irrigation of the face can help decrease the risk of hematoma and severe vascular complications. There are multiple injection techniques proposed for the middle third, in this article we present a simple, safe and effective technique with satisfactory results and lower risk

RESUMO

PURPOSE: The study aimed to evaluate and compare the efficacy and safety of treating atrophied labia majora with hyaluronic acid (HA) and calcium hydroxyapatite (CaHA). METHODS: Ten participants complaining of sagging or loss of volume in the labia majora were evaluated and randomly assigned to two groups-treated with CaHA or AH. Photographic documentation was taken and appreciated by the participants and by blind observers. RESULTS: The study showed an improvement in labia majora regarding volumization and flaccidity that was more significant after 90 days of treatment in both treatments. Besides flaccidity, volume replacement resulted in better balance and proportion between the labia majora and labia minora. The evaluators, independent and blind, judged that in 80% of the cases of the HA group and in 50% of cases of the CaHA group, there was an excellent improvement. CONCLUSION: CaHA and HA are both effective and safe for treating the intimate region, and this study cannot prove the superiority of one over the other. An appropriate assessment involving the analysis of sagging and/or volume loss and the creation of a sequential treatment protocol, involving CaHA and HA, seems to be the best solution. LEVEL OF EVIDENCE I: Evidence obtained from at least one properly designed randomized controlled trial. This journal requires that authors assign a level of evidence to each article.

RESUMO

Treatment with injectable fillers is considered to be intrinsically associated with the understanding of facial anatomy and appropriate techniques. However, a more comprehensive understanding of facial structure is critical to improving facial shape. This article presents two Nonsurgical approaches developed from the MD Codes system denominated "The 7-point Shape" and "The 9-point Shape." Both techniques were designed to help create a more feminine and masculine look, respectively. The aim is to provide foundation for the midface (cheek) and contour for the lower face (chin and jawline) and indirectly improve the facial signs that patients usually focus on when looking for aesthetic treatment (lines, folds, jowls, double chin, etc.). The MD Codes platform aims to deliver an alternative to surgery with injectables. The 7-point Shape and The 9-point Shape may provide visible results immediately after treatment.

RESUMO

BACKGROUND: Botulinum toxin type A (BontA) is the most frequent treatment for facial wrinkles, but its effectiveness and safety have not previously been assessed in a Cochrane Review. OBJECTIVES: To assess the effects of all commercially available botulinum toxin type A products for the treatment of any type of facial wrinkles. SEARCH METHODS: We searched the following databases up to May 2020: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers, and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs). SELECTION CRITERIA: We included RCTs with over 50 participants, comparing BontA versus placebo, other types of BontA, or fillers (hyaluronic acid), for treating facial wrinkles in adults. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Primary outcomes were participant assessment of success and major adverse events (AEs) (eyelid ptosis, eyelid sensory disorder, strabismus). Secondary outcomes included physician assessment of success; proportion of participants with at least one AE and duration of treatment effect. We used GRADE to assess the certainty of the evidence for each outcome. MAIN RESULTS: We included 65 RCTs, involving 14,919 randomised participants. Most participants were female, aged 18 to 65 years. All participants were outpatients (private office or day clinic). Study duration was between one week and one year. No studies were assessed as low risk of bias in all domains; the overall risk of bias was unclear for most studies. The most common comparator was placebo (36 studies). An active control was used in 19 studies. There were eight dose-ranging studies of onabotulinumtoxinA, and a small number of studies compared against fillers. Treatment was given in one cycle (54 studies), two cycles (three studies), or three or more cycles (eight studies). The treated regions were glabella (43 studies), crow's feet (seven studies), forehead (two studies), perioral (two studies), full face (one study), or more than two regions (nine studies). Most studies analysed moderate to severe wrinkles; mean duration of treatment was 20 weeks. The following results summarise the main comparisons, based on studies of one treatment cycle for the glabella. AEs were collected over the duration of these studies (over four to 24 weeks). Compared to placebo, onabotulinumtoxinA-20 U probably has a higher success rate when assessed by participants (risk ratio (RR) 19.45, 95% confidence interval (CI) 8.60 to 43.99; 575 participants; 4 studies; moderate-certainty evidence) or physicians (RR 17.10, 95% CI 10.07 to 29.05; 1339 participants; 7 studies; moderate-certainty evidence) at week four. Major AEs are probably higher with onabotulinumtoxinA-20 U (Peto OR 3.62, 95% CI 1.50 to 8.74; 1390 participants; 8 studies; moderate-certainty evidence), but there may be no difference in any AEs (RR 1.14, 95% CI 0.89 to 1.45; 1388 participants; 8 studies; low-certainty evidence). Compared to placebo, abobotulinumtoxinA-50 U has a higher participant-assessed success rate at week four (RR 21.22, 95% CI 7.40 to 60.56; 915 participants; 6 studies; high-certainty evidence); and probably has a higher physician-assessed success rate (RR 14.93, 95% CI 8.09 to 27.55; 1059 participants; 7 studies; moderate-certainty evidence). There are probably more major AEs with abobotulinumtoxinA-50 U (Peto OR 3.36, 95% CI 0.88 to 12.87; 1294 participants; 7 studies; moderate-certainty evidence). Any AE may be more common with abobotulinumtoxinA-50 U (RR 1.25, 95% CI 1.05 to 1.49; 1471 participants; 8 studies; low-certainty evidence). Compared to placebo, incobotulinumtoxinA-20 U probably has a higher participant-assessed success rate at week four (RR 66.57, 95% CI 13.50 to 328.28; 547 participants; 2 studies; moderate-certainty evidence), and physician-assessed success rate (RR 134.62, 95% CI 19.05 to 951.45; 547 participants; 2 studies; moderate-certainty evidence). Major AEs were not observed (547 participants; 2 studies; moderate-certainty evidence). There may be no difference between groups in any AEs (RR 1.17, 95% CI 0.90 to 1.53; 547 participants; 2 studies; low-certainty evidence). AbobotulinumtoxinA-50 U is no different to onabotulinumtoxinA-20 U in participant-assessed success rate (RR 1.00, 95% CI 0.92 to 1.08, 388 participants, 1 study, high-certainty evidence) and physician-assessed success rate (RR 1.01, 95% CI 0.95 to 1.06; 388 participants; 1 study; high-certainty evidence) at week four. Major AEs are probably more likely in the abobotulinumtoxinA-50 U group than the onabotulinumtoxinA-20 U group (Peto OR 2.65, 95% CI 0.77 to 9.09; 433 participants; 1 study; moderate-certainty evidence). There is probably no difference in any AE (RR 1.02, 95% CI 0.67 to 1.54; 492 participants; 2 studies; moderate-certainty evidence). IncobotulinumtoxinA-24 U may be no different to onabotulinumtoxinA-24 U in physician-assessed success rate at week four (RR 1.01, 95% CI 0.96 to 1.05; 381 participants; 1 study; low-certainty evidence) (participant assessment was not measured). One participant reported ptosis with onabotulinumtoxinA, but we are uncertain of the risk of AEs (Peto OR 0.02, 95% CI 0.00 to 1.77; 381 participants; 1 study; very low-certainty evidence). Compared to placebo, daxibotulinumtoxinA-40 U probably has a higher participant-assessed success rate (RR 21.10, 95% CI 11.31 to 39.34; 683 participants; 2 studies; moderate-certainty evidence) and physician-assessed success rate (RR 23.40, 95% CI 12.56 to 43.61; 683 participants; 2 studies; moderate-certainty evidence) at week four. Major AEs were not observed (716 participants; 2 studies; moderate-certainty evidence). There may be an increase in any AE with daxibotulinumtoxinA compared to placebo (RR 2.23, 95% CI 1.46 to 3.40; 716 participants; 2 studies; moderate-certainty evidence). Major AEs reported were mainly ptosis; BontA is also known to carry a risk of strabismus or eyelid sensory disorders. AUTHORS' CONCLUSIONS: BontA treatment reduces wrinkles within four weeks of treatment, but probably increases risk of ptosis. We found several heterogeneous studies (different types or doses of BontA, number of cycles, and different facial regions) hindering meta-analyses. The certainty of the evidence for effectiveness outcomes was high, low or moderate; for AEs, very low to moderate. Future RCTs should compare the most common BontA (onabotulinumtoxinA, abobotulinumtoxinA, incobotulinumtoxinA, daxibotulinumtoxinA, prabotulinumtoxinA) and evaluate long-term outcomes. There is a lack of evidence about the effects of multiple cycles of BontA, frequency of major AEs, duration of effect, efficacy of recently-approved BontA and comparisons with other treatments.

RESUMO

Introdução: A rinoplastia é uma cirurgia que muitas vezes apresenta resultados imprevisíveis, mesmo em mãos de cirurgiões experientes. Neste sentido, a rinomodelação com preenchedores é um procedimento não-cirúrgico para corrigir pequenas alterações externas nasais em casos específicos. Métodos: Os autores descrevem a técnica de aplicação de preenchedores (ácido hialurônico ou hidroxiapatita de cálcio) para modelação nasal. Foram incluídos todos os pacientes submetidos ao preenchimento nasal, entre 2009 e 2012. Foi avaliado o edema da ponta nasal, a dor e o grau de satisfação dos pacientes com o resultado. Resultados: Foram incluídos 39 pacientes no estudo. Com relação aos desfechos analisados com ácido hialurônico: 52% apresentaram edema leve; 74% tiveram dor leve; 15% se mostraram muito satisfeitos e 74% satisfeitos com o resultado. Com relação aos pacientes submetidos à rinomodelação com hidroxiapatita de cálcio: 67% apresentaram edema moderado; 50% dor moderada; 17% dor intensa e 84% se mostraram satisfeitos com o resultado. Conclusão: A rinomodelação com preenchedores reabsorvíveis é um procedimento simples, com resultados estéticos aceitáveis, sendo necessário um profundo conhecimento anatômico para diminuir o risco de complicações.


Introduction: Rhinoplasty often leads to unpredictable results, even in the hands of experienced surgeons. However, in specific cases, rhinomodelation with fillers, a non-surgical procedure to correct minor nasal external changes, can be used. Methods: This study describes the application technique of fillers (hyaluronic acid or calcium hydroxyapatite) for nasal modeling. Patients undergoing nasal filling between 2009 and 2012 were included. Edema of the nasal tip, pain, and the degree of patient satisfaction with the outcome were assessed. Results: Thirty-nine patients were included in the study. Regarding the outcomes of rhinomodelation with hyaluronic acid, 52% patients presented with mild edema, 74% had mild pain, 15% were very satisfied, and 74% were satisfied with the result. For the outcomes of rhinomodelation with calcium hydroxyapatite, 67% patients presented with moderate edema, 50% had moderate pain; 17% had severe pain, and 84% were satisfied with the result. Conclusion: Rhinomodelation with resorbable fillers is a simple procedure with acceptable esthetic results. However, a deep anatomical knowledge is necessary to decrease the risk of complications.

RESUMO

BACKGROUND: Breast augmentation with implants is one of the most commonly performed plastic surgical procedures, but has potential complications-asymmetry, implant displacement, rippling and wrinkling, capsular contracture, late seromas, and benign and malignant tumors-and potential financial costs. The auto-augmentation procedure, with mastopexy and lipofilling, is a second option to offer to patients who do not desire to continue with breast implants in secondary procedures. OBJECTIVE: This study aimed to present a series of patients who intended to quit having breast implants, and they went to an auto-augmentation procedure, with mastopexy and lipofilling. METHOD: The study included patients who underwent a mastopexy plus lipofilling following breast implant removal. The indications for the surgical procedure were: desire of not having breast implants anymore and smaller breasts, capsular contracture, and implant rupture. The surgical procedure is detailed. Fat grafting and mastopexy are done immediately at the time of explantation. RESULTS: A total of 26 patients (mean age 59.1 years) underwent mastopexy plus lipofilling following breast implant removal. The mean follow-up was 18 months. The mean amount of lipofilling was 258 cc. No major complications were observed, no infection, dehiscence, hematoma, or seroma. One patient had an oil cyst which was handled with resection. CONCLUSION: The auto-augmentation procedure after implant removal with local flaps and lipofilling is the better option for patients in whom breast implants are not an option anymore. Complication and reoperation rates are low and patient satisfaction is good. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

RESUMO

Color differences in skin are due to the amount and distribution of epidermal melanin. The number of melanocytes is almost the same in all skin types, but higher phototypes exhibit more melanocytes, which produce more melanin and melanosomes that are individually distributed throughout the keratinocyte layers. This characteristic ensures a natural, significant photoprotection in darker skins. Asians are a population with various skin phototypes, ranging from type III to IV Fitzpatrick's classification in Chinese and Japanese to type IV and V in Indian and Pakistani people. Asian skin tends to present postinflammatory hyperpigmentation, melasma, lentigines and freckles, nevus of Ota, and Hori nevus. The main skin diseases reported in Asians are acne, atopic dermatitis, and viral infections. Wrinkles and skin thickness, early signs of aging in Caucasians, are less evident in Asian skin. However, pigmentary changes occur earlier. Additionally, this ethnic population is increasing worldwide. The aim of this study is to show the importance of studying the characteristics of Asian skin for the better management of skin diseases in this population, which are being increasingly observed in doctor's offices. Based on a broad review of the medical literature, we report the characteristics of Asian skin, as well as some dyschromias and common skin disorders in this ethnic group. The objective of the article is to study the characteristics of Asian skin and differences in relation to other ethnic groups to achieve improved clinical and cosmetic management of diseases and other skin disorders. This article will discuss the concept of beauty in different ethnic groups, treatments with lasers and other light sources, and cosmiatric treatments in Asian skin. An extensive review of the literature was performed using the databases Scielo and Bireme, from Medline and Lilacs sources, over the last 50 years. The keywords used were as follows: Asian skin, ethnic skin, melanin. Due to the peculiarities of each ethnic group, this article demonstrates the importance of studying the characteristics of Asian skin to elucidate improved cosmiatric approaches for these patients.

RESUMO

BACKGROUND: Polymethyl methacrylate (PMMA) is a dermatologic filler commonly used in esthetic procedures. However, it can also be used in more severe cases such as reconstruction of facial traumas. AIMS: The aim of this report was to describe the use of PMMA in a nasal reconstruction of a patient victim of an automobilist accident which presented previous rejection of autograft. PATIENT: A young female patient, 26 y, victim of automobilist accident, with no bone support due to trauma both in the mandibulum and maxilla, presented fracture of several facial bones. Presented rejection of a bone autograft from the skullcap implanted on the nose. In order to harmonize the facial aspect, a nasal fill with PMMA for the anatomic reconstruction of the nose was performed. RESULTS AND CONCLUSIONS: PMMA promoted the recovery of facial and nasal esthetic characteristics of the patient ensuring a satisfactory result.

RESUMO

BACKGROUND: An unfortunate consequence of severe acne is scarring, which can have serious psychosocial consequences. Available methods for treating acne scars have varying degrees of effectiveness. OBJECTIVE: This nonrandomized, retrospective pilot study assessed the safety and effectiveness of combining microfocused ultrasound with visualization (MFU-V; Ultherapy®) and a calcium hydroxylapatite dermal filler (CaHA; Radiesse®) for treating atrophic acne scars. METHODS: Healthy subjects 35-55 years old with moderate-to-severe facial acne scars were enrolled. MFU-V was applied bilaterally using two transducers with focal depths of 3.0 and 1.5 mm. Using a cross-hatch pattern, 75 treatment lines were applied 2-3 mm apart. Immediately afterward, the same areas were injected with 1.5 mL of CaHA diluted with 1.5 mL of lidocaine 2% without epinephrine. Scar severity changes were assessed by two independent physicians using the Goodman Acne Scar Scale at post-treatment Day 90. Subject satisfaction was assessed with a questionnaire. RESULTS: Treated subjects (N = 10) achieved significant overall improvement in baseline acne scar severity (P = 0.002). When stratified by severity, a clear trend was apparent with the greatest improvement observed among subjects with severe scars. Subjects were very satisfied (n = 9) or satisfied (n = 1) with their aesthetic results. No adverse events were observed. CONCLUSIONS: Combining MFU-V and diluted CaHA is effective for treating atrophic acne scars.
