Synchronous jawbone diseases: a multicenter retrospective study.

The aim of this study is to report an original case series of synchronous jawbone diseases. Data of patients seen over 13 years were extracted from the files of three Oral Radiology and Pathology diagnostic centers in Brazil. The clinical, radiographic, and laboratory characteristics were tabulated and analyzed by the authors; the patients were described according to lesion type. Seventy-two synchronous jawbone diseases were included in this study. Florid osseous dysplasia, Gorlin-Goltz syndrome, and cherubism were the most frequent disorders reported in this case series. In addition, the posterior mandible area was the main site of manifestation. Florid osseous dysplasia and Gorlin-Goltz syndrome represented two-thirds of our samples. With the utilization of adequate demographic, clinical, and radiologic information, it is possible to diagnose most of the synchronous lesions of jawbones. Sometimes, however, we need complementary exams, such as histopathologic and biochemical analysis or dosing of calcium, phosphorus, and alkaline phosphatase.

A Rare Case of Desmoplastic Fibroma. Spontaneous Mandibular Regeneration with 3 Years Follow up - Case Report.

Desmoplastic fibroma is a benign, rare, but locally aggressive lesion. The intraosseous type rarely presents in the jaws. Desmoplastic fibroma represents the intraosseous counterpart of the soft tissue fibromatoses or desmoid tumor, affects predominantly young people with an affinity for the mandible. The aim of this article is to describe a rare case of spontaneous bone regeneration after resection of intraosseous type of Desmoplastic fibroma. We report a case of intraosseous Desmoplastic fibroma involving right body and ramus of the mandible of a 17 years old, male patient, that underwent surgical procedure by Risdon access to remove all lesion with 1 cm free margins and reconstructed with 2.4 mm plate. After 3 years follow up, spontaneous bone regeneration was found with no signs of recurrence of the lesion. In conclusion, cases of spontaneous bone regeneration after mandibular resection is rare and there are few studies and case report in the literature.

Tratamento conservador de osteomielite em mandibula: relato de caso / Conservative treatment osteomyelitis in jaw: case report / Tratamiento conservador de osteomielita en mandible: reporte de caso

Introdução: As infecções nos ossos de face podem acometer os maxilares, geralmente a mandíbula, apresentando diversos fatores etiológicos, além de seu potencial multibacteriano. Embora tratamentos mais radicais possam ser uma escolha preferencial, meios conservadores podem surgir como alternativa afim de evitar tratamento mais agressivo aos pacientes. Relato de caso: Paciente do sexo feminino, 17 anos de idade, vítima de acidente náutico foi submetido a tratamento cirúrgico para osteossíntese de fratura complexa de mandíbula e após um período de 30 dias houve evolução de um quadro de osteomielite em região mandibular no qual foi preconizado tratamento conservador com antibioticoterapia e orientações de restrição de dieta líquida e pastosa.

Tumor odontogênico adenomatoide folicular em maxila: relato de caso / Follicular adenomatoid odontogenic tumor in maxilla: case report

Tumor odontogênico adenomatoide (TOA) é uma lesão benigna incomum de origem odontogênica, caracterizado pelo crescimento lento, progressivo, indolor, de consistência firme, cujo tamanho, normalmente não atinge grandes proporções. Há predileção pela região anterior de maxila e o envolvimento de um dente impactado; geralmente o canino, é recorrente, caracterizando a variante folicular. O TOA apresenta três variantes: folicular, extrafolicular e periférica, que não se distinguem microscopicamente, porém são diferenciadas com achados clínicos ou imaginológicos. O presente trabalho descreve um caso de tumor odontogênico adenomatoide folicular, presente em maxila tratado por enucleação e curetagem. O paciente encontra-se em acompanhamento pós-cirúrgico de 30 meses, sem quaisquer sinais clínicos e radiográficos de recidivas da lesão... (AU)

Adenomatoid odontogenic tumor (AOT) is an uncommon benign lesion of odontogenic origin, characterized by slow growth, progressive painless, firm consistency, with size that normally does not reach large proportions. There is a predilection for the anterior maxilla and the involvement of an impacted tooth, usually the canine, is recurrent, featuring follicular variant. The TOA have three variants: follicular, extrafollicular and peripheral, which are not distinguishable microscopically, but clinically or imaging. This paperdescribes a case of follicular adenomatoid odontogenic tumor present in the maxilla, treated by enucleation and curettage with 30 months follow-up without clinical and radiographic signs of injury recurrence...

p-Akt and its relationship with clinicopathological features and survival in oral squamous cell carcinoma: an immunohistochemical study.

BACKGROUND: The aim of this study was to evaluate, through immunohistochemical reaction in samples of oral squamous cell carcinoma, the correlation between the expression status of protein kinase B (p-Akt) and patient survival as well as histological grade and some clinicopathological features. METHODS: Samples were collected from 46 patients with oral squamous cell carcinoma. The immunohistochemical expression of p-Akt was analysed, as were clinicopathological features including the use of tobacco, tumour stage, size and infiltration of metastatic lymph nodes. The association of immunostaining with histological grade was analysed in 40 patients. The associations were examined for statistical significance using a chi-square test. Overall survival rates were estimated by the Kaplan-Meier method and compared using a log rank test (P > 0.05). RESULTS: The results indicated a statistically significant association with p-Akt immunostaining for the variables lymph node metastasis (P = 0.006), tumour size (P = 0.044) and survival rate (P = 0.0298). CONCLUSION: From these results, the present study suggests that high p-Akt expression found in oral squamous cell carcinoma patients may contribute to tumour growth, metastasis to regional lymph nodes and shorter survival time.

Reconstrução nasal parcial com retalho frontal oblíquo: relato de caso / Partial nasal reconstruction partial with an oblique frontal flap: a case report

Os ferimentos avulsivos na região nasal podem ser de origem traumática ou patológica. A reconstrução desses defeitos apresenta grande complexidade devido à região nasal ser importante do ponto de vista funcional e estético. A escolha do método reconstrutivo é baseada no tamanho, na localização e na profundidade do defeito a ser corrigido. O objetivo deste trabalho é relatar o caso de uma paciente que apresentou avulsão parcial de nariz cujo tratamento cirúrgico proposto foi a reconstrução nasal por meio de retalho frontal oblíquo.

The avulsive wound of the nose may be of traumatic or pathological origin. The reconstruction of these wounds is difficult because the nasal region is functionally and aesthetically important. The method of treatment is based on size, localization and depth of the defect to be corrected. The aim of this study is to present a case report of a partial avulsive wound of the nose treated surgically by nasal reconstruction using an oblique frontal flap.
