Vascular complications with injection implants: treatment with hyperbaric chamber.

INTRODUCTION: The use of facial fillers has increased over the years because they are less invasive and present lower risks and faster results, along with shorter recovery time. OBJECTIVE: This study aimed to analyze the use of hyperbaric oxygen therapy as a possible treatment for vascular complications resulting from facial fillers. METHODOLOGY: This is a retrospective study of a series of patients treated at with hyperbaric oxygen therapy at the Brazilian Institute for Hyperbaric Oxygen Therapy (Instituto de Oxigenoterapia Hiperbárica do Brasil), after vascular complications from facial fillers. CONCLUSION: The association of oxygen therapy in a hyperbaric chamber with the conventional protocol for treating vascular occlusion from facial filler procedures was found to be effective.

Gluteal Augmentation with Polymethyl Methacrylate: A 10-year Cohort Study.

BACKGROUND: Many techniques for buttocks augmentation have been developed and published, for a more natural, satisfactory, and safe result for the patient. It has been a challenge to find a technique that presented not only volume gain but also gluteal remodeling. METHODS: A total of 1,681 patients who underwent gluteal augmentation with Polymethyl methacrylate (PMMA) between 2009 and 2018 were selected for this retrospective cohort study. Data collected included demographics, procedures data, and postoperative outcomes. Side effects were calculated and compared using the Student's t test. RESULTS: A total of 1,681 patients (1,583 women and 98 men) who underwent 2,770 gluteal fillings had their cases retrospectively analyzed. They were injected with 540,751.00 mL of PMMA injected. The patients' mean age was 39 years, and the mean volume injected in each section was 237 mL during the first procedure and 147 mL during the second procedure. The authors observed 52 cases presenting side effects, representing a rate of 1.88% of 2,770 procedures carried out. The statistically significant (P = 0.02) presence of side effects was detected in relation to the total filling volume. CONCLUSIONS: This study has demonstrated that gluteal augmentation with PMMA is one of the best options for this type of procedure. In addition, the findings suggest that the guidelines concerning gluteal augmentation must include PMMA filler as an option because PMMA proved to cause few side effects, as demonstrated by this patient cohort.

Replacement of gluteal implants by polymethyl methacrylate filler: case report.

Silicone prostheses are an alternative to shape the buttock but further studies are still needed to support the effectiveness of its use. A patient sought medical attention for being dissatisfied with the glutaeal silicone prostheses inserted using subcutaneous technique four years before. The treatment adopted was prosthesis removal surgery, and subsequent filling with PMMA.

Aesthetic correction of lesion by post-liposuction corticoid infiltration using subcision, PMMA filling, and CO2 laser.

INTRODUCTION: Post-liposuction fibrosis is a relatively common complication which can be repaired. CASE REPORT: We report a case of cutaneous atrophy and diffuse irregularity of the abdominal region with achromia post-liposuction. She was treated with subcision, PMMA filler and fractioned CO2 laser. RESULTS: Cutaneous colour and irregularities get improved.

Remoção de tatuagem com laser Q-switched NdYAG em população brasileira / Tattoo removal with Q-switched Nd: YAG laser in a Brazilian population

INTRODUÇÃO: Na prática da remoção de tatuagem, já foram utilizadas a dermo a brasão e a cirurgia. Atualmente, se utiliza o laser. O objetivo deste trabalho foi avaliar a remoção de tatuagens utilizando-se o laser Q-switched NdYAG. MÉTODO: Estudo retrospectivo, com pacientes tratados com laser Q-switched NdYAG. Foram coletados dados a partir de prontuários e fotos dos pacientes, e de contato por telefone ou e-mail. A análise estatística foi feita através da análise de distribuição, regressão multivariada e regressão logística. RESULTADOS: Foram avaliados 304 pacientes com média de idade de 29,8 anos (±7,86), sendo que 297 (97,69%) foram classificados como brancos (fotótipos I, II e III); destes, 270 (88,81%) haviam feito tatuagens profissionais. A tatuagem mais antiga tinha 360 meses e a mais recente, um mês, obtendo-se uma média de 64,56 meses (± 63,54). O tamanho das tatuagens foi, em média, de 12,92 cm, sendo preta a cor predominante, estando presente em 291(86,51%) tatuagens. A média de sessões por paciente foi de 3,77 sessões (±2,99) e o intervalo entre estas foi de 49,23 dias. Com isso, foi observado, pelo terapeuta, que 52,96% das tatuagens foram parcialmente removidas; 21,38%, não removidas; 86,51%, cicatrização normal; 8,55%, cicatriz hipertrófica, e 3,29%, queloide. Dos 304 pacientes, 26,64% (81) relataram estar satisfeitos e 58,88% (179) relataram estar parcialmente satisfeitos com o resultado. A hipocromia esteve presente em 33,55% (102) dos indivíduos. CONCLUSÕES: O laser Q-switched NdYAG é um método seguro e eficaz, apresentando bom grau de satisfação e poucos efeitos indesejáveis na remoção de tatuagem.

INTRODUCTION: Both dermabrasion and surgery have been used in the practice of tattoo removal. Currently, laser is also being used. The aim of this study is to evaluate tattoo removal with Q-switched Nd:YAG laser. METHOD: This is a retrospective study on patients treated by using Q-switched Nd:YAG laser. The data were collected from medical records and patient photographs, and through phone or e-mail contact. Statistical tests were done through the analysis of distribution, multivariate regression, and logistic regression. RESULTS: A total of 304 patients with an average age of 29.8 years (±7.86 years) were assessed. Of the total, 297 (97.69%) were classified as white (phototypes I, II, and III), 270 (88.81%) of whom had professional tattoos done. The oldest tattoo was 360 months old and the most recent was 1 month old, with an average of 64.56 months (±63.54 months). The tattoo size was, on average, 12.92 cm, with black being the predominant color (i.e., present in 291 [86.51%] tattoos). The average number of sessions per patient was 3.77 (±2.99), and the interval between sessions was 49.23 days. The therapist observed that 52.96% of the tattoos were partially removed, 21.38% were not removed, 86.51% showed normal healing, 8.55% developed a hypertrophic scar, and 3.29% developed a keloid. Of the 304 patients, 81 (26.64%) reported being satisfied and 179 (58.88%) reported being partially satisfied with the outcome. Hypochromia was present in 102 (33.55%) patients. CONCLUSIONS: Q-switched Nd:YAG laser is a safe and effective method for tattoo removal that results in a good degree of patient satisfaction and few undesirable effects.
