Prevalência tomográfica de variações anatômicas no complexo nasossinusal em pacientes com sinusite não odontogênica / Tomographic prevalence of anatomical variations in the nasosinusal complex in patients with non-odontogenic sinusitis

Objetivo: O objetivo do estudo foi avaliar a prevalência de variações anatômicas no complexo nasossinusal por meio de tomografia computadorizada (TC) em pacientes com sinusite não odontogênica. Métodos: Um estudo observacional e retrospectivo consistiu em 860 prontuários com indicação de tomografias computadorizadas multislice para avaliação de sinusite. A sinusite odontogênica foi caracterizada pela presença de espessamento da mucosa sinusal maior que 2 milímetros e ausência de alterações dentárias na região. Posteriormente, foram avaliadas as variações do complexo nasossinusal e realizada uma análise descritiva. Em seguida, 33 tomografias computadorizadas foram analisadas com sinusopatia não odontogênica, e o complexo nasossinusal foi avaliado quanto à presença das seguintes variações anatômicas como desvio do septo nasal associado a esporão ósseo, concha média bolhos, aumento do seio frontal entre outras. Resultados: Variações anatômicas foram observadas em 87,9% dos casos, sendo 15 do gênero masculino (46,0%) e 18 do gênero feminino (54,0%) e distribuídos em 45,5% dos pacientes entre 41-60 anos. A variação anatômica mais frequente foi a concha média bolhosa (37,9%), seguida de septações no seio maxilar (10,3%) e seio frontal alargado (13,8%). Conclusão:Verificou-se uma considerável incidência de variações anatômicas associadas à sinusite não odontogênica, com evidência para a concha média bolhosa.

Aim: The aim of the study was to assess the prevalence of anatomical variations in the sinonasal complex using computed tomography (CT) in patients with non-odontogenic sinusitis. Methods: This observational and retrospective study involved the analysis of 860 multislice CT scans prescribed for sinusitis evaluation. Non-odontogenic sinusitis was characterized by the presence of sinus mucosal thickening exceeding 2 millimeters and the absence of dental changes in the region. Subsequently, sinonasal complex variations were evaluated, and a descriptive analysis was conducted. Subsequently, 33 CT scans with non-odontogenic sinusopathy were analyzed, and the sinonasal complex was evaluated for the presence of the following anatomical variations: deviation of the nasal septum associated with a bony spur, bullous middle concha, unilateral hypoplasia of the maxillary sinus, among others. Results: Anatomical variations were observed in 87.9% of cases, with 15 males (46.0%) and 18 female (54.0%), distributed among patients aged 41-60 years (45.5%). The most frequent anatomical variation was the bullous middle concha (37.9%), followed by septations in the maxillary sinus (10.3%) and enlarged frontal sinus (13.8%). Conclusion: A considerable incidence of anatomical variations associated with non-odontogenic sinusitis was observed, with evidence of a bullous middle concha.

The interval since first symptoms until diagnosis of squamous cell carcinoma in the head and neck region is still a problem in southern Brazil

BACKGROUND: The aim was to examine the interval since first symptoms until final diagnosis of squamous cell carcinoma (SCC) in the head and neck region in southern Brazil. MATERIAL AND METHODS: The individuals were prospectively selected and underwent anamnesis, physical examination and interview in the first medical consultation at a Cancer Hospital from south of Brazil. RESULTS: From 488 patients who underwent clinical examination, 105 were included in the study with diagnosis of SCC. Patients average interval from first symptoms to final diagnosis was 152 days (median 86; max: 1105; min: 1), the average professional interval was 108 days (median: 97; max: 525; min: 1), and the average total period interval was 258 days (median: 186; max: 1177; min: 45). Factors statistically associated with patient and diagnosis itinerary intervals were smoking and poorly adapted dentures and distance from home to hospital, respectively. CONCLUSIONS: The identification of the itinerary characteristics of this specific population may reflect in more effective public policies, such as primary and secondary prevention programs, aiming to increase the survival of oncological patient. Furthermore, the knowledge of the variables that influence the late diagnosis minimizes patient's journey in search of care to cancer centers through health programs

Impaction of primary tooth molar in mandibule ­ case report / Primeiro molar decíduo impactado em mandíbula - relato de caso

Tooth impaction results from a mechanical blocking that prevents the tooth from erupt. This situation is frequently associated to permanent tooth as wisdom teeth and canines. Impaction of a primary tooth can be associated to systemic or local etiologic factors. Treatment options could include dental extraction, removal of lesion associated without removing the primary tooth and others. The aim of this article is to present a rare case report of an impacted primary tooth in a 42 yearold man, with no complain of swelling. Extra oral examination revealed no alteration of normality. The panoramic radiograph showed a primary tooth impacted in the left body of the mandible. Most of the time the cause for non-eruption of primary tooth is the presence of a mechanical obstacle, not anatomical, in its trajectory. The surgical intervention is a possibility, but it can stay unaltered with no problems related to the impacted tooth. Many times the professional experience and the activity together in various areas of knowledge are the most important and wise conduct to be taken in health care.(AU)

A impactação dental resulta de um bloqueio mecânico que impede o dente de erupcionar. Esta situação está frequentemente associada à dentes permanentes como os terceiros molares e os caninos. Impactação de um dente decíduo pode estar associada a fatores sistêmicos ou locais. Opções de tratamento podem incluir extração dental, remoção da lesão associada sem remoção do dente decíduo, entre outros. O objetivo deste artigo é apresentar um raro relato de caso de um dente decíduo impactado em um paciente do gênero masculino, 42 anos de idade, sem queixas de inchaço. A avaliação extra-bucal não mostrou alterações de normalidade. A radiografia panorâmica evidenciou um dente decíduo impactado em corpo de mandíbula, lado esquerdo. Na maioria dos casos a causa para não erupção de um dente decíduo é a presença de um obstáculo mecânico, não anatômico, em sua trajetória de erupção. A intervenção cirúrgica é uma possibilidade, mas pode permanecer inalterada sem problemas relacionados ao dente impactado. Em muitos casos a experiência profissional e a atividade em conjunto com várias áreas do conhecimento são as condutas mais importantes e sábias a serem tomadas no cuidado em saúde.(AU)

Inflammatory Myofibroblastic Tumor: Rare Manifestation in Face.

Inflammatory myofibroblastic tumor, also known as inflammatory pseudotumor and plasma cell granuloma, is a tumor that occurs most often in the lungs, abdomen, skin, soft tissue, genital system, and mediastinal. Before surgery, the diagnosis is difficult to establish because of its diverse manifestations. In the head and neck, manifestation is rare and may occur in the upper respiratory tract, soft tissues, orbits, and skull base. This article aims to report a rare manifestation of the disease in the face, highlighting the importance of a correct diagnosis to determine the most appropriate form of treatment, in male patient, leucoderma, 22 years old, with complain of a painless unilateral growth in the left cheek, beginning 2 months before and with progressive growth.
