Simple mandibular bone cyst, bibliographic review of the literature and presentation of a series of cases.

Abstract

The simple bone cyst (SBC) (also called unicameral bone cyst) is a benign bone cavity, without epithelial lining, which may contain serous to bloody fluid and occasionally connective tissue membranes that generate septations inside. It is a lesion of idiopathic origin and in most cases asymptomatic, so its finding is usually in radiographic controls, presenting an image of a radiolucent, well-defined lesion with an irregular border. It causes thinning of the bone tables, which can generate pathological fractures of the affected bone, especially in long bones, which is why they are usually intervened in order to promote bone repair. Epidemiologically, SBC represents 3% of primary bone lesions, and it manifests more frequently in males (over female in a 2:1 ratio) during the second decade of life, with a predilection for long bones, and for the mandible when it manifests itself in the maxillofacial territory. In this article, 3 cases of SBC in the mandible will be presented along with a review of the available literature.
