ABSTRACT

Introdução: Os retalhos interpolados são opções cirúrgicas eficazes para reconstruções de defeitos cutâneos em várias áreas do corpo, inclusive na face. O retalho proposto dispensa cuidados pós-operatórios com o pedículo exposto e pode ser realizado em tempo único. O objetivo é avaliar a utilidade do retalho interpolado de sulco nasogeniano (RISN) em ilha, na reconstrução de segmentos nasais e do canto interno da órbita, bem como discutir refinamentos em seu design e execução. Métodos: Estudo retrospectivo de prontuários de pacientes com defeitos nasais ou de canto interno da órbita, e que foram reparados com retalho interpolado do sulco nasogeniano. Todos os retalhos foram confeccionados de maneira randômica, realizando-se túnel subcutâneo para evitar pedículo exposto e cicatriz que comunicasse a área doadora e o defeito. Resultados: cinco pacientes foram incluídos no estudo, com idade entre 30 e 92 anos. Em todos os casos foi realizada biópsia de congelação intraoperatória que revelou margens livres de doença, orientando a extensão da ressecção. O CBC foi encontrado em 4 pacientes e o CEC em um paciente. Não houve complicações como sangramento pós-operatório ou necrose. Bons resultados funcionais e estéticos foram alcançados em todos os pacientes. Discussão: Vale ressaltar a versatilidade do retalho nasogeniano interpolado, sendo capaz de auxiliar na reconstrução de defeitos extensos não apenas de asa, ponta e columela nasais, mas também de dorso e canto medial do olho. Destaca-se também o aspecto estético mais favorável do pedículo do retalho interpolado em ilha comparado ao de transposição. Conclusão: O RISN interpolado em único estágio é uma opção confiável na reconstrução de segmentos faciais. Apresenta boa vascularização, possibilidade se ser realizado em único tempo e pode ser utilizado para cobertura nos locais onde há poucas opções reconstrutivas disponíveis.


Introduction: Interpolation flaps are effective surgical options for reconstructing skin defects in various areas of the body, including the face. The proposed flap does not require postoperative care with the pedicle exposed and can be performed in a single surgery. The objective is to evaluate the usefulness of the nasolabial interpolation island flap (NIF) for reconstructing nasal segments and the inner corner of the eye, as well as discuss improvements in its design and performance. Methods: In this retrospective study, medical records of patients with nasal defects that were repaired with a nasolabial interpolation flap were reviewed. All flaps were created with a subcutaneous tunnel to avoid pedicle exposure and prevent scar connection with the donor area and the defect. Results: Five patients aged 30­92 years were included. In all cases, intraoperative frozen biopsy revealed disease-free margins, indicating the extent of the resection. Basal cell carcinoma was found in four patients and squamous cell carcinoma in one. There were no complications such as postoperative bleeding or necrosis. Good functional and aesthetic results were achieved. Discussion: The NIF can help in the reconstruction of extensive defects of the nasal ala, tip, columella, and medial dorsum as well as the corner of the eye. We also highlight the more favorable aesthetic aspect of the pedicle in the interpolation island versus transposition flap. Conclusion: The single-stage NIF flap is a reliable option for reconstructing facial segments as it has good vascularization, can be performed in a single surgery, and can be used to cover places where few other reconstructive options are available.

ABSTRACT

Abstract The subunit principle in nasal reconstruction proposed the concept of reconstructing the specific topographic subunits that were identified as dorsum, tip, columella, the paired alae, sidewalls, and soft triangles. In patients with more than 50% of subunit loss, removing the remaining portion of the subunit and reconstructing the entire subunit may yield better results. The placement of incisions along the borders of the subunits minimizes scar lines. Furthermore, as trapdoor contraction occurs, the entire restored subunit bulges in a way that mimics the normal contour of a nasal tip, dorsum or ala. Two cases of nasal reconstruction that followed this important principle are described.

ABSTRACT

INTRODUÇÃO: A técnica de Bernard modificada por Webster é considerada por diversos autores a primeira escolha para reconstrução total de lábio inferior. Ela preserva as linhas e pontos de referência estética da face, e proporciona boa sensibilidade no lábio reconstruído, permitindo alcançar resultados estéticos e funcionais satisfatórios. Apesar de concordar com os princípios da técnica de Webster, uma modificação é proposta visando aperfeiçoar a reconstrução do vermelhão, usando retalhos nasogenianos bilaterais associados aos retalhos de avançamento originais. MÉTODOS: São apresentados cinco casos operados pelo autor no período de 2003 a 2008, e os resultados são discutidos. RESULTADOS: Demonstrou-se que a dissecção necessária para avançar os retalhos da bochecha na técnica de Bernard-Webster não inviabiliza os retalhos nasogenianos, e estes podem ser rotados adequadamente para acrescentar pele e volume ao vermelhão reconstruído. CONCLUSÃO: A modificação proposta não impõe risco aumentado ou prejuízo sobre a técnica original, e mantém ou aumenta a sua capacidade reconstrutiva.


INTRODUCTION: Many authors consider the Bernard technique modified by Webster the first choice for total lower lip reconstruction. This technique preserves skin folds and anatomical landmarks on the face, and interferes minimally with the tactile sensibility of the reconstructed lip, resulting in satisfying cosmetic and functional outcomes. Despite agreeing with the principles of the Webster technique, a modification is proposed to improve reconstruction of vermilion, by using bilateral nasolabial flaps associated with the original advancement flaps. METHODS: We report five surgical cases carried out between 2003 and 2008, and discussion of results. RESULTS: Dissection need to advance flaps in Bernard-Webster technique does not make nasolabial flaps unviable, and they can be rotated properly to add volume and skin to the reconstructed vermilion. CONCLUSION: Proposed modification of Bernard-Webster technique does not increase risk or damage compared with classic technique, and it maintains the same reconstructive capabilities or even enhances it.

ABSTRACT

O uso de implantes sintéticos para o preenchimento na face pode acarretar reações adversas. Estas podem ocorrer da má técnica ou decorrentes do produto. Entre os materiais utilizados, está o polimetilmetacrilato (PMMA) na forma de microesferas. Trata-se do relato de um caso de reação nodular na face de paciente do sexo feminino, após 15 anos do uso de implante de Artecoll®, produto composto por microesferas de colágeno bovino e PMMA. Foi tratada com laser de gás carbônico. Evidenciou-se o efeito tardio provocado da aplicação de implantes sintéticos na face como o Artecoll®, os fatores limitantes para ressecção convencional com bisturi e tesoura, e a opção da utilização do laser de CO2. Destacando-se a função ablativa e precisa na remoção do tecido comprometido, a preservação dos tecidos sadios e nobres, o grande potencial hemostático e a baixa morbidade, com menor cicatriz, edema, equimose e a rápida recuperação pós-operatória.


The use of synthetic implants as dermal facial fillers may cause adverse reactions, which may occur owing to inappropriate techniques or the intrinsic nature of the product. Polymethylmetacrylate (PMMA) microspheres is one of the materials used. This is a report of a case of nodular reaction in the face of a female patient, after 15 years of Artecoll® implant use, a product composed of microspheres of bovine collagen and PMMA. She was treated with a carbon dioxide laser. The delayed effect caused by the application of synthetic implants in the face, such as Artecoll®; the limiting factors of conventional resection with a scalpel and scissors; and the option for the use of carbon dioxide laser are outlined. Highlighted are the ablative and precise functions in the removal of compromised tissue, the preservation of healthy and noble tissues, the high hemostatic potential, and low morbidity, with smaller scars, edema, ecchymosis, and rapid postoperative recovery.

ABSTRACT

Recently, injectable dermal fillers have become important alternatives to surgical procedures for the correction of facial wrinkles. Bovine collagen is the first approved material for filler injection, and several studies have shown its efficacy. However, the risk of developing an allergic reaction and xenogenic transmission of bovine spongiform encephalopathy remain among its disadvantages. In this randomized, double-blinded, split-face study, we compared the efficacy and safety of a porcine collagen filler (TheraFill(R)) with that of a bovine collagen filler (KOKEN(R)) for nasolabial fold correction. A total of sixty one patients with mild to severe nasolabial fold were randomized to receive TheraFill(R) and KOKEN(R) on contralateral sides of the face. During the 12-month follow-up period, improvement in the Wrinkle-Severity Rating Scale score was slightly higher in TheraFill(R) group than KOKEN(R) group, although the difference was not statistically significant. No serious adverse reactions were observed and both materials were tolerable in most cases. In conclusion, the long-term effect of TheraFill(R) on nasolabial fold correction was comparable to that of KOKEN(R), and it may be a good alternative to bovine collagen filler.

ABSTRACT

El 50% de las malformaciones arteriovenosas (MAVs) de alto flujo se ubican en la región craneofacial y pueden producir sangrado con riesgo vital sin diagnóstico y tratamiento adecuado. La resonancia magnética (RM) es útil en el diagnóstico diferencial de las lesiones vasculares, siendo el gold standard la angiografía selectiva. Dado que las MAVs de alto flujo no involucionan espontáneamente, el tratamiento usualmente consiste en embolización con posterior resección quirúrgica. Se presenta un paciente de sexo masculino de 20 años que consulta por aumento de volumen nasogeniano derecho, progresivo, violáceo, blando y pulsátil. Se objetiva mediante RM una zona de vasos serpentiginosos, que se extiende desde el subcutáneo hasta la pared anterior del maxilar. La angiografía cerebral confirma MAV de alto flujo e informa mapeo vascular. Se decide embolización prequirúrgica superselectiva con posterior resección tumoral mediante acceso transvestibular.


The 50 % of arteriovenous malformations (AVMs) of high flow are located in the craniofacial region and can cause life-threatening bleeding without a diagnosis and appropriate treatment. Magnetic resonance imaging is useful in the differential diagnosis of vascular lesions, being the gold standard selective angiography. Since high-flowA VMs do not regress spontaneously, treatment usually involves surgical resection with subsequent embolization. We present a 20 years male patient consulting with a purple, progressive, soft, pulsating enlargement of right-side nasogenian region. Magnetic resonance imaging shows serpiginous vessels, extending from the subcutaneous to the anterior wall of the maxillary. Cerebral angiography confirms high flowAVM and shows vascular mapping. It was decided superselective preoperative embolization with subsequent tumor by transvestibular access.

ABSTRACT

BACKGROUND: During aging, the vermilion border of the upper lip wrinkles, stretches, and inverts because of the sphincteric action of the orbicularis oris muscle. Furthermore, a decrease of the nasolabial angle can be observed because of maxillary retropositioning. Most techniques for lip shortening do not affect this angle. In this study, a treatment approach is proposed that addresses all of these signs of aging. METHODS: During a 1-year period, a procedure was performed on 10 patients using the following techniques: 1. transverse incision of the skin of the nasal floor and bilateral alar margin; 2. cutaneous detachment of the entire upper lip up to the mucocutaneous transition; 3. stabilization of the nostrils with a transcolumellar nylon stitch; 4. elevation of the released skin by elliptical skin resection at the alar margin and a trapezoid segment resection at the nasal floor; 5. use of nylon and absorbable sutures to approach the dermis and close the skin, respectively. RESULTS: Adequate results were observed in 9 of the 10 patients, characterized by shortening and projection of the upper lip, vermilion eversion, reduced incidence of rhagades, and improvements of the nasolabial angle. In 1 patient with unilateral paralysis of the lip, no significant correction of the asymmetry was achieved. CONCLUSIONS: The proposed "double duck" technique proved to be simple and effective, with successful resolution of nasolabial defects and effective concealment of scars.


INTRODUÇÃO: Durante o envelhecimento, o lábio superior sofre enrugamento, alongamento e inversão do vermelhão, em decorrência da ação esfinctérica do músculo orbicular dos lábios. Além disso, a retrusão da parede anterior da maxila provoca diminuição do ângulo nasolabial. A maioria das técnicas para encurtamento labial não obtém a abertura desse ângulo. Neste trabalho, é proposta uma abordagem que contemple o tratamento de todos esses sinais de envelhecimento. MÉTODO: No período de um ano, foram operados 10 pacientes pela seguinte técnica: 1. incisão transversa da pele do assoalho nasal e margem alar bilateral; 2. descolamento cutâneo de todo o lábio superior até a transição cutaneomucosa; 3. estabilização das asas nasais com ponto transcolumelar; 4. elevação da pele descolada, com ressecção elíptica do segmento justa-alar e trapezoide do segmento do assoalho nasal; e 5. suturas dérmica, com fio de náilon, e epidérmica, com fio absorvível. RESULTADOS: Encurtamento e projeção do lábio com eversão do vermelhão, diminuição das rágades e abertura do ângulo nasolabial adequados foram obtidos em 9 dos 10 pacientes. Em um paciente que apresentava paralisia unilateral do lábio, não houve correção significativa da assimetria. CONCLUSÕES: A técnica proposta mostrou-se de simples realização, de resolução efetiva dos objetivos e com boa ocultação das cicatrizes.

ABSTRACT

El descenso del panículo adiposo malar de la mejilla es la causa fundamental de los signos de envejecimiento del tercio medio facial. En el último decenio se han empleado diferentes técnicas para la reposición de este a partir de una modificación de la ritidectomía compuesta de Hamra. Presentamos el estudio de 20 pacientes, a los cuales se les realizó disección, elevación y fijación del panículo adiposo malar a través de una incisión de blefaroplastia. Con la técnica empleada se logró la movilización y el ascenso de la mejilla, el consiguiente acortamiento de la distancia entre el borde palpebral y el surco orbitomalar y la profundización del punto medio de la mejilla. En el 80 por ciento de los pacientes se lograron buenos resultados estéticos, dados por una apariencia de rejuvenecimiento de la región medio facial con atenuación del pliegue nasolabial y ascenso del surco orbitomalar. No se presentaron complicaciones relacionadas directamente con el procedimiento quirúrgico(AU)


The descent of the panículo fatty malar of the cheek is the fundamental cause of the signs of aging of the half facial third. In the last decade different techniques have been used for the reinstatement of this starting from a modification of the ritidectomía made up of Hamra. We present the study of 20 patients, to which were carried out dissection, elevation and fixation of the panículo fatty malar through a blefaroplastia incision. With the technique employee it was achieved the mobilization and the ascent of the cheek, the rising reduction of the distance between the border palpebral and the furrow orbitomalar and the profundización of the half point of the cheek. By 80 percent of the patients good aesthetic results were achieved, given by an appearance of rejuvenecimiento of the half facial region with attenuation of the pleat nasolabial and ascent of the furrow orbitomalar. Related complications were not presented directly with the surgical procedure(AU)
