Osteoma is the most frequent benign tumor in the craniomaxillofacial region. The most common initial manifestation is facial pressure or headache. The clinical examination showed increased volume in the right supraorbital region, asymmetry of the orbital contour, exophthalmia, dystopia, proptosis and clinical restraint of ocular movement for supraversion. The lesion measured approximately 4 cm in diameter with irregular contour. Osteotomy was performed with saw surrounding the tumor, with aid of a surgical piezo on the orbital medial wall. The result of histopathological examination was osteoma. The patient is 2.5 years postoperatively and so far without complications.

Dentigerous cysts are the second most common odontogenic cysts of the jaws, and sometimes inhibit the eruption of teeth. Almost all of the dentigerous cyst encloses the crown of an unerupted tooth and the radiolucent area is attached to the tooth at the cementoenamel junction. Dentigerous cyst is more common in male patients and most commonly develop in the second and third decades of life. Clinically, a localized swelling of the alveolar bone can be detected, however, dentigerous cysts can be asymptomatic during a long period of time, leading to a significant destruction of bone. The conventional treatment plan is cyst removal and marsupialization. Marsupialization therapy can be useful to promote the spontaneous eruption of the involved tooth within the cyst. However, tooth eruption does not always occur spontaneously after marsupialization. This article aims to report a clinical case of the diagnosis and treatment of a dentigerous cyst in the maxilla associated with an unerupted canine in a pediatric patient and discussion of the treatment performed.

Orbital trapdoor fractures are characterized by tissue entrapment between the fractured bone fragment and the remnant of the orbital floor. This entrapment can result in immediate local and systemic complications and poor outcomes when approached late. This article presents the case of an orbital floor fracture in a child with dystopia, pain, edema and entrapment of the inferior rectus muscle and consequent limitation of ocular motility. The strategy proposed in the early approach to orbital floor reconstruction and release of incarcerated tissue allowed the patient to achieve satisfactory results without morbidity, as compared to the outcomes of corrective sequel surgery.

Pure orbital wall fractures represent until 25% of the facial fractures and its reconstruction it's considering a challenge for the maxillofacial surgeons. There are many biomaterials used to repair these fractures according to the literature however, the most common are the titanium mesh and autogenous bone graft. The aim of this work is to report a rare case of blow-in roof orbital fracture associated to an intracranial hematoma in the cranium base.

O tratamento com implantes dentários tem evoluído significativamente desde a década de 70 até os dias atuais, tanto na questão de planejamento quanto na bioengenharia e tratamento da superfície desses implantes, com o objetivo de tornar o tratamento mais eficaz. Atualmente o uso de implantes imediatos tem sido cada vez mais estudado pelos pesquisadores e utilizado para a reabilitação oral dos pacientes. A literatura nos mostra que a inserção imediata de implantes dentários pós-extração é um tipo de tratamento com altas taxas de sucesso, possibilitando ao paciente ser submetido a apenas uma cirurgia, retorno à função mastigatória e estética mais rápidas. Para isso são necessários planejamento correto e seleção adequada do paciente para o sucesso do tratamento, levando em consideração a condição óssea e periodontal. O objetivo deste estudo é discorrer sobre o planejamento da reabilitação oral de uma paciente que foi submetida da extração dentária total dos dentes inferiores, instalação de 4 implantes dentários imediatos e confecção de uma prótese total com carga imediata do tipo protocolo.

Mucormycosis is an opportunistic, and frequently lethal, fungal infection that occurs in patients with immunocompromised states, such as diabetes mellitus. This infection invades not only the paranasal sinuses, but also the maxillae, zygoma, and rhinocerebral structures, which results in massive destruction of the facial skeleton and soft tissue. It progresses in patients with underlying comorbidities, such as diabetes mellitus, haematologic malignancy, cerebral malignancy, renal failure, and systemic immunosuppression. Most cases occur in tropical countries. The relationship between mucormycosis and these underlying conditions has been widely discussed in the literature. This study sought to report the case of a patient diagnosed with glioblastoma and mucormycosis in the maxilla, who was successfully treated with surgery and isavuconazonium sulfate (Cresemba).
