Treatment of Fracture Sequel in the Mandibular Angle Region.

Because of the anterior disposition on the face and the fragility of the anatomy, the mandible is commonly affected in facial fractures, and the angle region represents 32% of the mandibular fractures; therefore, the objective of the paper was to present a proposal for late correction of the mandibular fracture already consolidated and with occlusal alteration. Patient J.C.P.R., 32, during anamnesis reported loss of sensibility in the mentalis region as well as unilateral posterior open bite for having been a victim of an automobile accident about 1 year and 3 months ago. Physical examination showed elevation in the right mandibular angle region due to the poor positioning of fractured stumps. It has been found that the patient suffered a simple fracture at the mandibular angle, but that had not been treated previously, and it was necessary to treat the fracture sequel. Refraction was performed with a new reduction and fixation through titanium plates and screws, showing that, even being late, the procedure to reduce the fracture sequela was effective, even with the correct functional occlusal adjustment.

Mandibular metastasis of adenocarcinoma from prostate cancer: case report according to epidemiology and current therapeutical trends of the advanced prostate cancer

Prostate cancer represents the most frequent non-cutaneous neoplasia in males. This type of neoplasia can develop peculiar patterns of evolution, presenting, in many cases, precocious relapses and metastasis. Bone metastasis in the mouth is extremely rare, and represents 1% of all malignant mouth neoplasias. The aim of the present study is to report a clinical case of bone metastasis in the mandibular region associated with a tumoral prostate adenocarcinoma, as well as to discuss connected aspects about diagnosis, prognosis and integrated treatment of this condition.

Ameloblastic carcinoma, primary type: case report, immunohistochemical analysis and literature review.

Ameloblastic carcinoma (AC) is a rare malignant odontogenic neoplasm with scarce reported cases in the literature and it can be confused with benign ameloblastoma (AM). This study reports a case of AC, and presents a literature review of AC classified into primary type (ACPt) or secondary type (ACSt) by the World Health Organization (WHO). The review addressed 31 cases published in the English literature between the years 2005 and 2011. The majority of cases were ACSt. The mandible was the most common site of occurrence for both AC types. All patients who died of their disease had ACSt. Tumors with plexiform pattern, hyperchromatism, mitosis and necrosis were associated with a higher ratio of histories of recurrence and death by disease, as well as the tumors with clear cells, especially in the ACSt. ACSt appeared to correlate with recurrence and mortality. The histological features may have different prognostic importance depending on the AC type.
