ABSTRACT

Objetivo: Analisar se os cirurgiões-dentistas têm conhecimento das implicações judiciais embutidas na cirurgia estética de bichectomia. Métodos: Trata-se de um estudo descritivo no qual foi aplicado um questionário estruturado aos docentes cirurgiões-dentistas da Faculdade Maria Milza (FAMAM) que realizam bichectomia. Os dados do questionário foram organizados em forma de tabela, apresentando informações sociodemográficas e sobre o conhecimento deles em relação aos aspectos judicias embutidos neste tipo de cirurgia. Resultados: A amostra foi composta por 08 cirurgiões-dentistas, docentes da Faculdade Maria Milza. A maioria era do sexo masculino, com idade entre 29 a 39 anos, com tempo de docência menor igual a 5 anos e atuando em clínica privada. A maioria afirmou estar ciente das possíveis implicações judiciais e se previnir destas, no entanto, grande parte da amostra estudada não tinha conhecimento do Código Civil Brasileiro. Conclusão: A maioria dos dentistas não possuíam conhecimento sobre o Código Civil Brasileiro, mas sabem que podem responder processos movidos pelos pacientes. Frente a isso, eles estão se protegendo de possíveis implicações de ordem judicial relacionados a cirurgia de bichectomia.(AU)


Objective: To analyze whether dentists are aware of the judicial implications embedded in cosmetic surgery for bichectomy. Methods: This is a descriptive study in which a structured questionnaire was applied to the professors-dentists at Faculdade Maria Milza (FAMAM) who perform bichectomy. The questionnaire data were organized in form of a table, presenting sociodemographic information and their knowledge in relation to the judicial aspects embedded in this type of surgery. Results: The sample consisted of 08 dental surgeons, professors at Faculdade Maria Milza. Most were male, aged between 29 and 39 years old, with less than 5 years of teaching experience and working in a private clinic. The majority claimed to be aware of the possible legal implications and to prevent them, however, a large part of the sample studied was not aware of the Brazilian Civil Code. Conclusion: Most surgeons had no knowledge of the Brazilian Civil Code, but they know that they can respond to a lawsuit brought by patients. Faced with this, they are protecting themselves from possible implications of a court order related to bichectomy surgery.(AU)

ABSTRACT

El cuerpo adiposo de la boca (CAB) es un componente adiposo multilobulado bien delimitado, localizado de manera bilateral en la región facial íntimamente relacionado a estructuras nerviosas y vasculares. La remoción de CAB es un procedimiento ampliamente estudiado en el campo de la cirugía maxilofacial, utilizado principalmente para cubrir defectos. Su influencia en la estética facial ha iniciado una popularización de la remoción de la extensión bucal de CAB para obtener un rostro más estilizado, intervención difundida como poco invasiva y sin complicaciones. El objetivo de este estudio fue recopilar y evaluar estudios que reporten y evalúen complicaciones asociadas a la remoción por razones estéticas de CAB. Se revisó la evidencia en las bases de datos Medline vía PubMed, Epistemonikos, Scopus y Google Scholar, utilizando términos predefinidos, seleccionando estudios primarios de reportes de casos. Se incluyeron 7 artículos con un total de 10 pacientes; de estos, ocho pacientes se realizaron este procedimiento en Brasil, uno en Estados Unidos y uno en Chile. La distribución de la población fue de 3:7 entre hombres y mujeres con edad promedio de 35 años y un rango entre los 23 a los 49 años. En relación a las complicaciones reportadas, 100 % de los pacientes presentaron asimetría facial, un 80 % presentó edema facial, 30 % manifestaron sialocele, Trismus 20 %, 40 % presentó hematoma, 20 % compromiso del estado general, 20 % presentaron disfagia, en los casos de hipoestesia, parestesia, absceso, seroma, parálisis facial, odinofagia, fiebre se expresaron en 10 % de la población estudiada. En todos los estudios se describió una reintervención quirúrgica posterior a la remoción estética del cuerpo adiposo de bichat. La escasa literatura y la baja calidad de esta, no permite estimar el porcentaje real de posibles complicaciones, tampoco es posible determinar sus resultados a largo plazo ya que no existe en la evidencia un seguimiento apropiado para estos pacientes.


The buccal adipose body (BAB) is a well- defined multilobulated adipose component, located bilaterally in the facial region, closely related to nervous and vascular structures. BAB removal is a widely studied procedure in the field of maxillofacial surgery, used mainly to cover defects. Its influence on facial aesthetics has started to popularize the removal of the BAB buccal extension to obtain a more stylized face, an intervention widely known as minimally invasive and without complications. The objective of this study was to collect and evaluate studies that report and evaluate complications associated with the removal of BAB for cosmetic reasons. The evidence was reviewed in the Medline databases via PubMed, Epistemonikos, Scopus, and Google Scholar, using predefined terms, selecting primary studies from case reports. 7 articles with a total of 10 patients were included; Of these, eight patients underwent this procedure in Brazil, one in the United States, and one in Chile. The distribution of the population was 3:7 between men and women with an average age of 35 years and a range between 23 to 49 years. In relation to the reported complications, 100 % of the patients presented facial asymmetry, 80 % presented facial edema, 30 % manifested sialocele, trismus 20 %, 40 % presented hematoma, 20 % compromised general state, 20 % presented dysphagia, in the cases of hypoesthesia, paresthesia, abscess, seroma, facial paralysis, odynophagia, fever were expressed in 10 % of the studied population. All the studies described a surgical reintervention after cosmetic removal of the bichat adipose body. The scarce literature and its low quality do not allow estimating the real percentage of possible complications, nor is it possible to determine their long-term results since there is no evidence of appropriate follow-up for these patients.

ABSTRACT

In the orthodontics process, intervention and sliding of an orthodontic bracket during the orthodontic process can arise large response of the labio-cheek soft tissue. Soft tissue damage and ulcers frequently happen at the early stage of orthodontic treatment. In the field of orthodontic medicine, qualitative analysis is always carried out through statistics of clinical cases, while quantitative explanation of bio-mechanical mechanism is lacking. For this purpose, finite element analysis of a three-dimensional labio-cheek-bracket-tooth model is conducted to quantify the bracket-induced mechanical response of the labio-cheek soft tissue, which involves complex coupling of contact nonlinearity, material nonlinearity and geometric nonlinearity. Firstly, based on the biological composition characteristics of labio-cheek, a second-order Ogden model is optimally selected to describe the adipose-like material of the labio-cheek soft tissue. Secondly, according to the characteristics of oral activity, a two-stage simulation model of bracket intervention and orthogonal sliding is established, and the key contact parameters are optimally set. Finally, the two-level analysis method of overall model and submodel is used to achieve efficient solution of high-precision strains in submodels based on the displacement boundary obtained from the overall model calculation. Calculation results with four typical tooth morphologies during orthodontic treatment show that: ① the maximum strain of soft tissue is distributed along the sharp edges of the bracket, consistent with the clinically observed profile of soft tissue deformation; ② the maximum strain of soft tissue is reduced as the teeth align, consistent with the clinical manifestation of common damage and ulcers at the beginning of orthodontic treatment and reduced patient discomfort at the end of treatment. The method in this paper can provide reference for relevant quantitative analysis studies in the field of orthodontic medical treatment at home and abroad, and further benefit to the product development analysis of new orthodontic devices.

ABSTRACT

Abstract We report a 40-year-old man, with an unremarkable personal and family history, who presented for evaluation of an asymptomatic papule located on his right cheek. Histopathology revealed an encapsulated neoplasm within the dermis; composed by narrow, elongated, and wavy cells with an ill-defined cytoplasm, dense chromatin and tapered ends interspersed with collagen fibers. Pathologic findings were consistent with tissue of Antoni B pattern. The diagnosis was an infraorbital schwannoma. The incidental finding of rare tumors like this, should make clinicians consider a greater spectrum of differential diagnoses for a unilateral skin-colored papule on the cheek of patients.

ABSTRACT

RESUMEN: El presente estudio busca entregar conocimientos y aspectos importantes de las estructuras anatómicas asociadas al cuerpo adiposo de la mejilla (CAM), a consecuencia del reporte de un caso de complicación posterior a una bichectomía. Conocer los elementos anatómicos y sus relaciones con el CAM es de vital importancia, ya que en la actualidad son muchos los cursos y pasadas que se realizan para odontólogos generales y especialistas para el retiro del CAM, esto producto de la creciente demanda estética de las personas por presentar un perfil más fino y estilizado. El caso presentado corresponde a una mujer que consultó al servicio de urgencia por aumento de volumen facial posterior a la extracción del CAM, el cual se diagnosticó como sialocele, consecutivo a daño del conduc- to parotídeo. Al revisar la literatura y observar en nuestros preparados anatómicos se aprecia la cercanía de elementos de importancia, como son el conducto parotídeo, los ramos cigomático y bucal del nervio facial, vasos faciales como la arteria facial, vena facial y arteria transversa facial, es por esto que es necesario conocer en detalle la zona a intervenir y considerar las posibles variaciones anatómicas de estos elementos, para así evitar dañarlos durante el procedimiento, tomando una actitud preventiva. Apuntado entonces al objetivo de este estudio, fue lograr entregar información anatómica precisa y concisa de los elementos de importancia próximos o inmersos en el CAM, para prevenir la iatrogenia de estos.


SUMMARY: The present study seeks to provide knowledge and important aspects of the anatomical structures associated with the buccal fat pad (BFP), as consequence of the report of a case of complication after bichectomy. Knowing the anatomical elements and their relationships with BFP is of vital importance, because nowadays there are too many BFP removal courses and internships, for general dentists and specialists, due to the increasing aesthetic demands of individuals seeking a finer and more stylized profile. The case presented is a female patient who consults the emergency department for an increase in facial volume after BFP extraction, which was diagnosed as sialocele, following damage to the parotid duct. When reviewing the literature and observing our anatomical preparations, the proximity of important elements is appreciated, such as the parotid duct, the zygomatic and buccal branches of the facial nerve, facial vessels such as the facial artery, facial vein and facial transverse artery. It is essential to know in detail the area in order to intervene and consider the possible anatomical variations of these elements to avoid injury during the procedure. The aimed objective of this study, is to provide accurate and concise anatomical information of important elements near or immersed in BFP, to prevent iatrogenesis.

ABSTRACT

ABSTRACT: Pleomorphic adenoma (PA), also called benign mixed tumor, is the most common tumor of the salivary glands. About 70 % of these tumors occur in the parotid gland and an uncommon site are the minor salivary glands. The most common sites of PA of the minor salivary glands are the palate followed by lips and cheek. Other rare reported sites include the fauces, floor of the mouth, tongue, tonsil, pharynx, retromolar area and nasal cavity. Here we report a case of pleomorphic adenoma of minor salivary glands of the cheek in a 22-year-old male. The mass was removed by wide local excision with adequate margins, and the patient was followed for 1-year post operatively with no recurrence.


RESUMEN: El adenoma pleomórfico (AP), conocido también como tumor mixto benigno, es el tumor más común de las glándulas salivales. Alrededor del 70 % de estos tumores ocurren en la glándula parótida y con menor frecuencia en las otras glándulas salivales. Los lugares más comunes de AP en las glándulas salivales son el paladar, seguido de labios y mejillas. Otros sitios poco frecuentes reportados, incluyen las fauces, el piso de la boca, la lengua, las tonsilas palatinas, la faringe, el área retromolar y la cavidad nasal. En este estudio se presenta un caso de adenoma pleomórfico de las glándulas salivales menores de la mejilla en un hombre de 22 años. Se extirpó la masa mediante escisión local amplia con márgenes adecuados, con un seguimiento del paciente durante un año después de la operación sin recurrencia.

ABSTRACT

Introdução: A bichectomia é um procedimento cirúrgico que remove parte do corpo adiposo bucal não apenas para fins estéticos, mas também funcionais, limitando o trauma recorrente na região jugal. A correta indicação cirúrgica e o auxílio de exames de imagem são essenciais para o planejamento cirúrgico e seleção da técnica a ser utilizada, minimizando as taxas de complicações e alcançando resultados seguros e satisfatórios. Objetivo: Relatar dois casos clínicos em que a bichectomia foi realizada, enfatizando a importância da ultrassonografia pré-operatória na determinação do volume do corpo adiposo bucal e abordando duas técnicas cirúrgicas. Relato de casos clínicos: Duas pacientes do sexo feminino (18 e 32 anos), normosistêmicas, relataram queixas de insatisfação estética com o contorno arredondado da face, além de trauma constante na mucosa jugal. Ao exame clínico, as pacientes apresentavam mucosa jugal de volume aumentado e traumatizado. A bichectomia foi realizada pelo acesso de Matarasso e pelo fundo de sulco. Conclusão: a ultrassonografia mostrou-se eficiente no planejamento cirúrgico da bichectomia, favorecendo a retirada do corpo adiposo da bochecha de forma previsível, rápida e segura. As duas técnicas cirúrgicas foram eficazes para remoção do corpo adiposo bucal(AU)


Introduction: Bichectomy is a surgical procedure that removes part of the buccal fat pad not only for esthetic but also functional purposes, limiting recurrent trauma in the jugal region. The correct surgical indication and the aid of imaging examinations are essential for the surgical planning and selection of the technique to be used, minimizing complication rates and achieving safe and satisfactory results. Objective: To report two clinical cases in which bichectomy was performed, emphasizing the importance of preoperative ultrasonography in determining the volume of the buccal fat pad. Report of clinical cases: Two female patients (18 and 32 years), normosistemic, reported complaints of aesthetic dissatisfaction with the rounded contour of the face, in addition to a constant complaint of trauma to the jugal mucosa. At the clinical examination, the patients presented jugal mucosa of increased and traumatized volume. A bichectomy was performed by Matarasso access and by the furrow fund. Conclusion: ultrasonography proved to be efficient in assisting the surgical planning of bichectomy, favoring the removal of the buccal fat pad in a predictable, fast and safe way. The two surgical techniques were effective for removal of the buccal fat pad(AU)

ABSTRACT

Introdução: Atualmente, a lipoplastia facial tem sido muito estudada, e isso se justifica em decorrência dos resultados estéticos, dentre eles a valorização da projeção do osso zigomático. Poucas técnicas cirúrgicas foram descritas, principalmente em relação ao resultado de satisfação e do acesso que é realizado para a remoção da bola de Bichat. Este estudo tem como objetivo realizar uma análise de banco de dados para avaliar a satisfação do procedimento de bichectomia pelos próprios pacientes, além de descrever uma abordagem cirúrgica distinta da encontrada na literatura. Metodologia: Foram selecionados 47 pacientes para o procedimento, sendo este realizado em nível ambulatorial, seguindo a mesma técnica cirúrgica em todos os pacientes, os quais foram acompanhados por 7, 14, 30 e 60 dias de pós-operatório, verificando-se o processo de cicatrização e dados referentes à satisfação em todas as consultas realizadas. Resultados: Mediante a técnica empregada, houve um bom número inicial de pacientes satisfeitos com a cirurgia, que aumentou gradativamente conforme o acompanhamento. Conclusões: Assim, confirma-se que a bichectomia é um procedimento seguro, com poucas complicações, devendo haver uma maior amplitude nas pesquisas que visem avaliar o grau de satisfação dos pacientes para atender melhor as suas expectativas... (AU)


Introduction: Facial lipoplasty has been widely studied today because of the aesthetic results provided, such as the enhancement of the ossozygomatic projection. Few surgical techniques have been described, mainly in regard to the satisfaction result and the access that is made for the removal of the bichat ball. The objective of the present study is to perform a database analysis to evaluate satisfaction of the bichectomy procedure by the patients themselves, in addition to describing a surgical approach distinct from that found in the literature. Methodology: 47 patients were selected for the procedure, and the procedure was performed on an outpatient basis, following the same surgical technique in all patients, which were followed for 7, 14, 30 and 60 postoperative days, and the healing process was verified and satisfaction data in all consultations. Results: As a result, it can be observed that by the technique employed, there was a good initial number of patients satisfied with the surgery, which increased gradually as the follow-up in the more returns. Conclusions: Thus, it is confirmed that bichectomy is a safe procedure, with few complications, and more research should be done to evaluate the degree of patient satisfaction to meet their expectations...

ABSTRACT

Introdução: A cirurgia de Bichectomia está sendo muito procurada por pessoas que visam diminuir o volume facial. O corpo adiposo da bochecha, ou bola de Bichat, possui uma complexa relação anatômica com estruturas faciais. Uma das complicações que o procedimento pode causar é a paralisia facial temporária ou permanente, em decorrência de injúrias causadas aos ramos terminais do nervo facial, devido à proximidade dessas duas estruturas anatômicas. Metodologia: O objetivo do presente artigo é enfatizar a relação anatômica da bola de Bichat com alguns ramos terminais do nervo facial através da dissecação de cadáveres. Foram feitas dissecações em três hemifaces de cadáveres humanos para a exposição do corpo adiposo da bochecha e dos ramos extracranianos do nervo facial. Resultados: A anatomia dos ramos terminais zigomáticos e bucais do nervo facial se mostrou variável em cada hemiface dissecada, mas sempre intimamente relacionados a bola de Bichat. Conclusões: O profissional que realiza a Bichectomia deve ter pleno conhecimento não só da técnica cirúrgica, mas também da variabilidade anatômica da região... (AU)


Introduction: The Buccal Fat Extraction surgery has been sought by people who aim to reduce facial volume. The Buccal fat pad has a complex anatomical correlation among the facial structures. The facial nerve paralysis is one of Bichat's fat extraction complications which might be temporary or permanent, due to the proximity of those anatomical structures. Methodology: The present article aims to emphasize the anatomical correlation between the Buccal fat pad and a few terminal branches of the facial nerve through the human cadaveric dissection. The dissection was performed on three human cadaveric hemifacial to expose the buccal fat pad body and the facial nerve extracranial branches. Results: The zygomatic and buccal terminal branches anatomy of the facial nerve has shown variables in each dissected hemifacial part. However, it has always presented closely related to Bichat's fat pad. Conclusions: The professional that performs the Buccal Fat Removal surgery must have to have the full knowledge not only about the surgical technique but the anatomical variability of the region, as well...

ABSTRACT

Ochronosis is a cutaneous disorder caused by the accumulation of phenols, either endogenously as homogentisic acid in patients with alkaptonuria (autosomal recessive disorder with deficiency of the enzyme homogentisic acid oxidase), or exogenously in patients using phenol products such as topical creams containing hydroquinone or the intramuscular application of antimalarial drugs. Exogenous ochronosis (EO) typically affects the face and was reported in patients with dark skin such as Black South Africans or Hispanics who use skin-lightening products containing hydroquinone for extended periods. Recently more cases have been reported worldwide even in patients with lighter skin tones, to include Eastern Indians, Asians, and Europeans. However, just 39 cases of EO have been reported in the US literature from 1983 to 2020. Here we present two cases; a 69 and a 45-year-old female who were seen for melasma, given hydroquinone 4% cream daily and tretinoin 0.05%. Both patients noticed brown spots on their cheeks, which progressively enlarged and darkened in color. The diagnosis of ochronosis was confirmed by characteristic histopathological features on the punch biopsy. Unfortunately, neither patient responded to multiple treatments (to include, tazarotene 0.1% gel and pimecrolimus ointment, topical corticosteroids, and avoidance of hydroquinone containing products). We also present a case of classic (endogenous) ochronosis in a patient with alkaptonuria to picture the histological similarities of these two entities. EO is an important clinical consideration because early diagnosis and treatment may offer the best outcome for this notoriously refractory clinical diagnosis.

ABSTRACT

Objective: A haemangioma is a benign vascular tumour consisting of an abnormal overgrowth of tiny blood vessels. Haemangioma may not be present at birth but may appear at 6 months of life. This vascular tumour is not common. We therefore report fifteen cases of haemangioma occurring in the oro-facial region: eight occurred in the cheek, one in the floor of the mouth, four in the lower lip and two in the maxillary gingivae. The objective of this study was to outline the clinical presentation and management of haemangioma in the oro-facial region treated in our Centre. Methods: This is a retrospective study of all the patients that were treated from July, 2009 to July, 2019. Information was extracted from case files of patients. Data collected included: age at presentation, sex, location of the tumour, treatment given, findings and histological diagnosis. Results: The result showed fifteen cases, nine (60.0%) were males and six (40.0%) females. Male to female ratio is 1.50 to 1.00. Our diagnostic tool was the aspiration of frank blood from the tumour which had similar clotting time with the normal blood and our mode of treatment included: injection of sclerosants and excision of the fibrous tissues. Conclusion: It is essential to treat the tumour as early as possible especially in large lesion with disfigurement or where it is complicated by haemorrhage or infection

ABSTRACT

A Cirurgia Plástica e a Odontologia constituem áreas intimamente envolvidas com a face, por ser esta "o cartão de visitas" do ser humano. O apelo estético está relacionado com a mídia, e também com a aceitação física e emocional. Uma estética harmoniosa representa um aumento da autoestima e uma demonstração de sucesso socioeconômico. A multidisciplinaridade tem ganho espaço nas ciências da saúde por representar uma associação de conceitos e técnicas entre diversos profissionais altamente especializados para a máxima performance dos resultados, trazendo realização e conforto para o paciente. Assim, a bichectomia é um procedimento contemporâneo que visa uma ressecção parcial do corpo adiposo da bochecha, com o intuito estético e funcional. Estético porque proporciona uma face mais harmônica; e funcional porque visa a correção de incômodos traumáticos promovidos por uma interferência na mastigação. O objetivo desta revisão sistemática foi ilustrar clínicos e pesquisadores sobre o procedimento cirúrgico (bichectomia) calcado em bases científicas evidenciáveis e em conhecimentos ético-legais.


Plastic surgery and Dentistry are areas closely involved with the face, as this is the "visiting card" of the human being. The aesthetic appeal is related to the media, but also to physical and emotional acceptance. A harmonious aesthetic represents a better self-esteem and a demonstration of socio-economic success. Multidisciplinarity has gained space in health sciences because it represents an association of concepts and techniques among several highly specialized professionals for maximum results performance, bringing achievement and comfort to the patient. Thus, bichectomy is a contemporary procedure that aims at a partial resection of the cheek adipose body for aesthetic and functional purposes. Aesthetic because it provides a more harmonious face; and functional because it aims to correct traumatic discomfort caused by interference with chewing. The aim of this systematic review was to illustrate clinicians and researchers about the surgical procedure (bichectomy) based on evidenced scientific and ethical-legal knowledge.

ABSTRACT

ABSTRACT Objective: To evaluate the effect of red propolis and L-lysine on angiogenesis and tumor growth in a new model of hamster cheek pouch inoculated with Walker 256 tumor cells. Methods: The study consisted of two experiments with four groups each (total: 57 hamsters). In the experiment 1, the animals were inoculated with Walker tumor cells, followed by administration of test substances (red propolis 200mg/5mL/kg or L-lysine 150mg/kg) or control substances (gum arabic 5mL/kg or water 5mL/kg) for 10 days. The animals in the experiment 2 received red propolis, L-lysine, gum arabic or water at the same doses, for 33 days prior to inoculation of Walker tumor cells, followed by 10 days of treatment with the same substances. Based on single-plane images, angiogenesis was quantified (mean vascular area), in percentage, and tumor area (mm2) and perimeter (mm). Results: In the experiment 1, compared to animals receiving water, the mean vascular area expressed in percentage was significantly smaller in animal treated with propolis (p<0.05) and L-lysine (p<0.001). Conclusion: Both red propolis and L-lysine inhibited tumor angiogenesis in the new hamster cheek pouch model when administered after tumor inoculation.


RESUMO Objetivo: Avaliar o efeito da própolis vermelha e da L-lisina na angiogênese e no crescimento tumoral em novo modelo de bolsa jugal de hamster inoculada com células de tumor de Walker 256. Métodos: O estudo consistiu em dois experimentos com quatro grupos cada (total: 57 hamsters). No experimento 1, os animais foram inoculados com células de tumor de Walker, tendo em seguida administradas as substâncias teste (própolis vermelha 200mg/5mL/kg ou L-lisina 150mg/kg) ou controle (goma arábica 5mL/kg ou água 5mL/kg) por 10 dias. Os animais do experimento 2 receberam própolis vermelha, L-lisina, goma arábica ou água nas mesmas doses, por 33 dias antes do inóculo das células de tumor de Walker, seguido por 10 dias de tratamento com as mesmas substâncias. Baseado em imagens em plano único, foram quantificados a angiogênese (área vascular média), em termos percentuais, e a área (mm2) e o perímetro (mm) do tumor. Resultados: Comparada aos animais que receberam água, a área vascular média, expressa em percentagem, foi significativamente menor nos animais tratados com própolis (p<0,05) e com L-lisina (p<0,001). Conclusão: Tanto a própolis vermelha quanto a L-lisina inibiram a angiogênese no novo modelo de bolsa jugal de hamsters, quando administradas após a inoculação do tumor.

ABSTRACT

Cactus spines can easily puncture the skin with only minor pressure. Removal of the offending cactus spine is the treatment of choice; however, it is very difficult, even with tweezers. A 17-year-old Korean girl presented for evaluation of multiple purple-colored macules and papules on the left cheek and left thumb. Two months earlier, she had pricked her finger and face on cactus spines while volunteering in Haiti. An ultrasound identified wedge-shaped echogenic materials suspected as cactus spines. We recommended surgical removal of the spines, but she vehemently refused. We then advised her to take amoxicillin/clavulanic acid and undergo regular follow-up. During the follow-up period, the spines dislodged spontaneously for easy removal and the patient removed them with tweezers. The lesions actually improved over the next several months. Here, we report this rare and interesting case for educational purposes because such a case has never been previously reported in Korea.

Basal cell carcinoma (BCC) is the most common malignant skin tumor that usually develops in the head and neck region. It has a wide range of histological variants and constitutes approximately 65% of epithelial tumors. Cutaneous plasma cell infiltration can occur in individuals with various disorders, including amyloidosis, plasma cell neoplasm, and infectious diseases such as syphilis and deep fungal infections. A 53-year-old woman presented with scaly erythematous plaque on the left cheek. Skin biopsy showed smooth-bordered collections of basaloid proliferation with epidermal connection, and fibrotic stromas were noted in the dermis. Notably, mixed inflammatory cells were noted in the upper dermis, and they were mainly plasma cells. There was no evidence of other organ involvement and infection. She was diagnosed with BCC with plasma cell infiltration and was treated with topical and oral steroid, and excision was performed. In our literature review, plasma cell infiltration is related to tumor ulceration and more likely to be seen in patients with high-risk BCCs. Herein, we report a peculiar case of BCC with plasma cell infiltration.

ABSTRACT

Cheilitis granulomatosa (CG) is a subset of orofacial granulomatosis (OFG) and considered to be a monosymptomatic form of Melkersson-Rosenthal syndrome (MRS), which is characterized by the triad of chronic lip swelling, facial paralysis, and fissured tongue. The labial swelling is thought to be associated with an orofacial swelling, which affects the chin, cheeks, and oral mucosa. Histologically, it is distinguished by noncaseating granulomas consisting of lymphohistiocytes and giant cells. Although systemic steroids with or without intralesional triamcinolone injections are the mainstay of treatment, and various agents have been proposed for this rare disease, no successful treatment modality has been reported in the literature yet. Herein, we present our experience with three different CG cases, which showed a varied level of positive response to the combination therapy.

ABSTRACT

OBJECTIVES: Endoscopic prelacrimal medial maxillectomy (EPMM) was previously reported to treat maxillary inverted papilloma. This study aimed to compare prelacrimal recess approach with the conventional Caldwell-Luc approach (CLA) to remove benign maxillary sinus tumors and to evaluate the usefulness of this approach based on our experience. METHODS: Ten patients who underwent EPMM at our hospital from January 2013 to December 2017 were reviewed. We also reviewed 30 patients who underwent benign maxillary sinus tumor resection via CLA during the same period. From medical records, postoperative pathological results, complications due to surgery, and recurrence rate were evaluated. RESULTS: There were eight inverted papilloma, one ameloblastoma, and one ossifying fibroma in the EPMM group. In the CLA group, all 30 cases were inverted papilloma. There were no cases of failure at gross total removal during surgery, and no recurrences were observed during follow-up in either groups. Mean follow-up period was 13.0 months in CLA group and 10.8 months in EPMM group. Regarding postoperative complications, 11 patients of the CLA group (37%) and three patients of the EPMM group (30%) had numbness around the cheek and upper lip area after surgery (P=0.715). In the CLA group, there were eight patients who had numbness lasting more than 3 months after surgery, and two patients had numbness for more than 1 year. However, facial numbness disappeared within 3 months in all patients in the EPMM group, in which epiphora was not observed. CONCLUSION: EPMM is the effective surgical approach for resecting benign maxillary sinus tumor compared with CLA. Although facial numbness was reported in EPMM, the duration of numbness was shorter than CLA.

ABSTRACT

Intraorbital infection shows a low incidence, but it might cause blindness or even death. This case is unusual in that its origin from a craniofacial bone fracture prior to infection of the maxillary sinus. A 33-year-old female patient was referred for right cheek swelling. When she visited the emergency room, we removed right cheek hematoma and bacterial examination was done. In the past, she had craniofacial bone surgical history due to a traffic accident 6 years ago. Next day, the swelling had remained with proptosis and pus was recognized in the conjunctiva. We planned an emergency operation and removed the pus which was already spread inside the orbit. And the evaluation for sinusitis was consulted to the otorhinolaryngology department simultaneously. There were Prevotella oralis and methicillin-resistant Staphylococcus epidermidis bacterial infection in the intraorbital and sinus respectively. Afterwards, the vigorous dressing was done for over a month with intravenous antibiotics. Though the intraorbital infection was resolved, blindness and extraocular movement limitation were inevitable. In conclusion, close follow up of the maxillary sinus in facial bone fracture patients is important and aggressive treatment is needed when an infection is diagnosed.

ABSTRACT

Dysplastic nevus is common and affects about 10% of the northern European-descendent population. Studies over the past several decades have identified dysplastic nevi as a risk factor for malignant melanoma. Furthermore, in rare cases, they confirmed that dysplastic nevi have progressed to melanoma. Cases in which dysplastic nevi progressed to malignant melanoma in multiple studies are not uncommon. A 35-year-old woman presented with the major symptom of multiple itchy brown nodules (2.0 cm× 1.3 cm) in the left cheek that had first appeared 20 years earlier. Complete excision was performed at the first visit; subsequent biopsy confirmed that they were dysplastic nevi. They recurred three times over 3 years at the same site, all of which were histologically diagnosed as dysplastic nevi. Five years after the final excision, a brownish nodule developed in the left cheek, with others at the left temporal region, right retroauricular region, and left shoulder at the same time. These lesions were histologically diagnosed as malignant melanoma. We experienced a case of malignant melanoma that occurred at the same site after three recurrences of dysplastic nevi. Although rare, the possibility of malignant melanoma should be considered in follow-ups in cases involving repeatedly recurrent dysplastic nevi.

ABSTRACT

BACKGROUND: Age-related changes in facial skin is a major concern in women. This study aimed to objectively evaluate normal skin elasticity and age-related differences in the faces of East Asian women. There are no standard values for data related to normal skin on East Asian women. METHODS: We studied 129 healthy East Asian women without a history of cosmetic procedures or surgeries. Skin elasticity was assessed at the cheek and lower eyelid points, which were assessed on both the right and left sides of the face. RESULTS: The age of the subjects showed significant negative correlations with the R2 and R7 parameters, which represent skin elasticity after deformation. CONCLUSION: We therefore concluded that the primary decrease in skin elasticity in East Asian women occurs in the midface region.
