ABSTRACT

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

ABSTRACT

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.

ABSTRACT

A utilização de biomateriais na tentativa de reparar ou substituir tecidos perdidos não é recente e evoluiu juntamente com os avanços da medicina regenerativa visando à maior qualidade de vida da população. Na Odontologia a compreensão dos aspectos biomiméticos envolvidos após implantação de biomateriais como substitutos de tecido mole é de suma importância na prática clínica, uma vez que o enxerto autógeno de gengiva, considerado padrão ouro, possui inúmeras limitações em relação à dimensão da área a ser reparada, tempo cirúrgico e dor pós-operatória na loja doadora. Esta revisão tem como objetivo reunir estudos que propõem a utilização de substitutos ao enxerto autógeno de palato, ressaltando suas aplicabilidades, contraindicações, disponibilidade no mercado, além de resultados clínicos.(AU)


The use of biomaterials to repair or replace lost tissues is not new and has evolved with advances in regenerative medicine aimed at higher quality of life of the population. In dentistry, the understanding of biomimetic aspects after implantation of biomaterials used as soft tissue replacements is significant in practice, since the autograft gum considered the gold standard has many limitations regarding the size of the area to berepaired surgical time and postoperative pain in the donor area.This review aims to bring together studies that propose substitutes to autograft palate, highlighting its applicability, contraindications, availability in the market, and clinical outcomes.

ABSTRACT

Os autores apresentam o caso de uma paciente submetida 7 anos após aplicação de polimetilmetacrilato (PMMA) a um facelift com implante de prótese mentoniana, o qual evoluiu com granuloma por corpo estranho em região distante da aplicação do preenchimento. Após quase um ano de tratamento, a paciente evoluiu com resolução do caso.


The authors present the case of a patient who underwent a facelift with a chin implant 7 years after polymethylmethacrylate (PMMA) implantation, which evolved with foreign body granuloma in a region distant from the filling application. After nearly a year of treatment, the patient evolved with resolution of the granuloma.

ABSTRACT

La rinomodelación es un procedimiento en el cual se utilizan materiales de relleno inyectables para modificar el perfil nasal. Han existido más de 150 rellenos dérmicos en el mercado global, pero ninguno logra reunir todas las características ideales. El polimetilmetacrilato (PMMA) ha sido utilizado en medicina por más de 50 años como relleno dérmico y ha sido aprobado por la FDA para su uso en corrección de pliegues nasolabiales. Tras la inyección de PMMA, las microesferas generan una respuesta inflamatoria a cuerpo extraño ya que no pueden ser fagocitadas por macrófagos ni por células gigantes, dado su tamaño, permaneciendo en el tejido inalteradas. El tejido de granulación y las fibras colágenas crecen en torno a las microesferas, encapsulándolas. Se considera un producto permanente ya que el PMMA no se degrada en el tiempo. La punta nasal es un área donde se pueden obtener buenos resultados con rellenos inyectables, pero debe ser tratada con pequeños volúmenes para evitar potenciales efectos adversos, principalmente el compromiso vascular de la piel. Presentamos el caso de un paciente sometido a rinoplastía no quirúrgica con inyección de PMMA (Metacrill®) en la punta nasal y su revisión quirúrgica secundaria.


Filler rhinoplasty is a procedure in which dermal fillers are used to alter the nasal profile without invasive surgery. There have been more than 150 fillers in the global market, though none of them are considered ideal. Polymethylmetacrylate (PMMA) has been used in medical practice for more than 50 years as a dermal filler and has been approved by the FDA for the correction of nasolabial folds. Once inyected, the PMMA micro spheres cause a foreign body inflammatory reaction, yet they cannot be removed by phagocytosis because of their large size, remaining unaltered in time. Granulation tissue and collagen fibers grow sorrounding and encapsulating the micro spheres. It is considered a permanent filler due to the remainance of the PMMA micro spheres in the skin. The nasal tip is an area easy to treat with fillers, though it must be managed with small volumes to avoid adverse reactions, mainly vascular compromise of the skin. We present the case of a patient who underwent a filler rhinoplasty with PMMA (Metacrill®) in the nasal tip and a subsequent secondary revision rhinoplasty.

ABSTRACT

A lipoenxertia de face, apesar de consagrada, não é isenta de riscos e complicações. Neste relato de caso, descrevemos de forma inédita uma complicação isquêmica local, causada por enxerto de gordura. Simultaneamente, propomos a terapêutica com Oxigenioterapia Hiperbárica para o tratamento desta situação, não se limitando exclusivamente à gordura, mas principalmente ao PMMA, em que esta complicação é muito mais frequente.


Facial fat grafting is not devoid of risks and complications, despite being a widely practiced procedure. In this case report, we describe a novel form of local ischemic complication that occurred secondary to fat grafting. Simultaneously, we propose Hyperbaric Oxygen therapy for the treatment of this situation. We propose that Hyperbaric Oxygen therapy should not be limited solely to fat graft-related ischemia, but should be effective in the management of the more frequently encountered complications associated with polymethylmethacrylate fillers.
