Tratamento conservador de fratura condilar por projétil de arma de fogo: relato de caso / Conservative treatment of fracture in condylar caused by projectile firearm: case report

Traumas por projétil de arma de fogo, na Bahia, têm incidência elevada na região maxilofacial, não raramente atingindo a região condilar, promovendo frequentemente fraturas cominuídas que dificultam a escolha do tratamento. A abordagem dessas fraturas condilares dependerá do deslocamento, grau de cominuição da fratura, adesão do paciente à terapêutica e resposta inicial ao tratamento. O rápido atendimento, com estabilização do quadro, é essencial para a prevenção de sequelas e reestabelecimento de uma oclusão adequada. Alternativas não cirúrgicas constituem modalidades terapêuticas seguras e preferíveis para casos de pequenas alterações de oclusão em pacientes colaboradores. O atendimento a pacientes vitimados por trauma na região da articulação têmporo mandibular visa em curto prazo solucionar queixas álgicas e fornecer estabilidade à região e a médio e longo tempo o objetivo é a prevenção de disfunção da articulação e anquilose, para isto o tratamento deve ser multidisciplinar com reestabelecimento da oclusão e reprogramação muscular. O objetivo do presente trabalho é descrever um caso clínico de fratura de côndilo por projétil de arma de fogo, tratado com bloqueio maxilo-mandibular e finalizado através de tratamento ortodôntico e acompanhamento fonoaudiológico

Injury by firearm projectile, in Bahia, have high incidence in the maxillofacial region, promoting comminuted fractures that often hinder the choice of treatment and prognosis. Addressing these condylar fractures depends on the displacement, degree of fracture comminution, patient adherence to therapeutic and initial treatment response initially proposed. The Prompt attending with stabilization, is essential to prevent sequelae and reestablishment of adequate occlusion. Alternative non surgical therapeutic modalities are safe and preferable for cases of small changes in occlusion in patients collaborators. The care of patients suffering trauma in temporomandibular joint aims to solve short-term pain complaints and provide stability to the region and the medium and long time goal is prevention of joint disorder and ankylosis, for this treatment should be multidisciplinary with reestablishment of occlusion and reprogramming muscle. The aim of this study is to describe a case of condylar fracture by projectile firearm, initially treated with maxillomandibular and finalized through orthodontic treatment and phonoaudiological therapy

Fossetas congênitas de lábio inferior: relato de caso. / Congenital lower lip pits: a case report

As fossetas labiais congênitas são achados clínicos raros, localizadas normalmente, na região do vermelhão do lábio inferior, bilateralmente à linha média. Classicamente, são associadas a quadros sindrômicos, como nas síndromes de Van der Woude(SVW), do Pterígio Popilíteo(SPP), na síndrome oro-facial-digital tipo1 e na síndrome de Niikawa-Kuroki, em ordem de prevalência. Este trabalho se destina ao relato de caso de um paciente acompanhado pelo serviço de CTBMF do Hospital Santo antônio, portador de fossetas labiais paramedianas bilaterais.

Congenital lip pits are rare clinical findings, usually located in the region of the lower lip vermilion border, bilaterally at the midline. They are classically associated with syndromes, as in the Van der Woude syndrome (VWS), popliteal pterygium syndrome (PPS), the oro-facial-digital syndrome type1, and Niikawa-Kuroki syndrome, in order of prevalence. This present study sets out to report two cases of patients suffering from bilateral paramedian lip pits, followed at the department of Traumatology and Bucco-maxillofacial Surgery of the Santo antônio Hospital.

Redução transcutânea de fratura de seio frontal sob anestesia local: relato de caso / Transcutaneous reduction of fracture of frontal sinus under local anesthesia: a case report

As fraturas do osso frontal são um problema pouco comum, quando comparadas a outros tipos de fraturas faciais. Ocorrem em cerca de 2 a 15% dos traumas de face. O osso frontal localiza-se em uma área nobre, próxima a estruturas importantes, como os olhos e o nariz, com a função de proteger a porção fronto-encefálica. quando traumatizado, pode produzir lesões nessas estruturas, além de importantes deformidades estéticas faciais. Os principais agentes etiológicos são os acidentes ciclísticos e motociclísticos 44-85%, as agressões físicas e quedas, havendo um maior acometimento entre os pacientes jovens (20-30 anos) e do gênero masculino (66-91%). O exame clínico, associado a exames de imagens de boa qualidade, são essenciais para auxiliar no diagnóstico e tratamento desse tipo de fratura, pois fornecem dados quanto à severidade do trauma e ao envolvimento de outras fraturas faciais, o que influencia a modalidade de tratamento a ser adotado. Dentre as formas mais comuns de tratamento, estão as abordagens via acessos translesionais, supraciliares ou por incisões coronais. O presente trabalho tem o objetivo de abordar e discutir o tema com a apresentação de um caso clínico de fratura da parede anterior do seio frontal tratado sob anestesia local.

Frontal bone fractures are an unusual problem compared to other kinds of fracture of facial bones, occurring in approximately 2 to 15% of facial traumas. The frontal bone is in a prime area, adjoining important structures such as the eyes and nose, and has a protective function for the anterior cephalic portion. When traumatized, it can produce lesions in these structures, as well as major aesthetic facial deformities. The main etiological agents are cycling and motorcycle accidents (44-85%), physical aggressions, and falls, and there is a higher incidence among young patients (20-30 years) and males (66-91%).The clinical examination, in association with high quality imaging studies, is essential for the diagnosis and treatment of this type of fracture because they provide data on the severity of the trauma the involvement of other facial fractures, which influences the type of treatment to be employed. among the commonest forms of treatment are the supraorbital approach, translesional pressure or coronal incisions. The present study sets out to approach the subject through the presentation of a case of anterior wall fracture of the frontal sinus treated under local anesthesia.

Histopathological study of radicular cysts diagnosed in a Brazilian population.

The aim of this study was to investigate the histopathological features of radicular cysts (RCs) diagnosed in a Brazilian population. Seventy-three cases of RCs, from a total of 1480 biopsies diagnosed between 2001 and 2008 at the Laboratory of Oral Surgical Pathology of the Dental School of the Federal University of Bahia were investigated regarding their histopathological features. Morphological results showed that exocytosis (n = 50), spongiosis (n = 40), acanthosis (n = 28), atrophic epithelium (n = 27) and apoptotic bodies (n = 21) were the most common findings. Other morphological findings included: foamy macrophages (n = 10), Russell's bodies (n = 7), cholesterol crystals (n = 7) and glandular-like odontogenic epithelial rests (n = 1). Evidence of exogenous material was seen in 16 samples. It was concluded that the clinical and histopathological findings observed in Brazilian patients were comparable with those described for other populations.

O propósito desse estudo foi investigar os aspectos histopatológicos de cistos radiculares diagnosticados em uma população brasileira. Setenta e três casos de cistos radiculares entre 1480 biópsias diagnosticadas na Faculdade de Odontologia da Universidade Federal da Bahia, entre 2001 e 2008, foram investigados, considerando os seus aspectos histopatológicos. Os resultados morfológicos mostraram que os achados mais comuns foram a exocitose (n=50), espongiose (n=40), acantose (n=28), epitélio atrófico (n=27) e células apoptóticas (n=21). Outros achados encontrados incluíram macrófagos espumosos (n=10), corpúsculos de Russell (n=7), imagens negativas de colesterol (n=7) e restos epiteliais odontogênicos semelhantes à tecido glandular (n=1). Material exógeno foi observado em 16 casos. Concluiu-se que os aspectos histopatológicos e clínicos observados foram comparáveis a outros descritos em outras populações.

Altered expression of cytokeratins in primary, recurrent and syndrome keratocystic odontogenic tumors.

Keratocystic odontogenic tumor (KOT) is a benign cystic tumor that affects the jaw bones and may be associated with the nevoid basal cell carcinoma syndrome (NBCCS). Twenty-five cases diagnosed as KOT, including primary and recurrent tumors and those associated with NBCCS, were submitted to immunohistochemical study for analysis of cytokeratins (CKs) 7, 8, 10, 13, 14, 18 and 19. The results showed CK13 immunostained on the intermediate layers and upper cells. CK14 was expressed in all epithelial layers and in those areas where inflammation and subepithelial splits were present; this protein was preserved within the basal cells. CK 18 was expressed mainly in the basal layer, whereas CK19 was expressed mainly on the intermediate and superficial layers. The remaining CKs tested were not immuoreactive. The status of maturation of cytokeratin seems to be altered on KOTs, and this is not distinct when different tumors are compared.
