A rare case of aneurysmal bone cyst (ABC) located in the mandibular condyle in a 10-year-old boy is presented. The patient came to our attention for a sudden swelling in the right temporomandibular region, the mouth opening was not reduced.A rapid growing mass, depicting soft tissue invasion, in the right condyle of the mandible was found. Clinically and radiographically it resembled to a malignant lesion. The surgical excision of the mandibular condyle allowed a complete removal of the lesion. The histological examination revealed a pseudocystic expanding osteolytic lesion containing blood-filled space separated by connective tissue and many osteoclastic giant cells, which was a conventional vascular ABC.The ABC is an infrequent bone lesion which can only be found very rarely at the craniofacial skeleton. There have been described about 160 cases of ABC originated in the molar region or in upper maxilla and even more rare is the location of this cyst in the mandibular condyle. Only 6 cases were reported in the literature to date.A complete surgical resection of this osteolytic lesion is the treatment of choice considering its high recurrence rate. The condyle was not replaced with any graft. Therefore a functional device was used after surgery to overcome the lack of the condyle and to stimulate the growth of the ramus.
Fanconi Anemia is a rare autosomal recessive disorder characterized by various congenital malformations, progressive bone marrow failure at a very young age and of solid tumors development. The authors present a rare case of a squamous cell carcinoma of the hard palate in a Fanconi Anaemia patient. The atypical clinical manifestation rendered the diagnosis more difficult. This case, for age of appearance, sex and localization, is unique in international literature. We recommend a quarterly follow up of the oral-rhino-pharynx complex in FA patients and to consider as carcinomas, all oral lesions that last more than two weeks.
Loss of autofluorescence as an early phenomenon associated with tissue degeneration seems to be promising for the diagnosis of oral cancer. The method seems to make visible early structural and biochemical alterations of the oral mucosa not always evident under direct inspection of the oral cavity. For this reason, the margins of the mucosal lesions usually appear wider compared with direct visualization. Actual extension of the potentially malignant lesions must be precisely perceived to avoid any underestimation of the tumor. In this study, 32 patients at risk for oral cancer underwent autofluorescence test. Of these patients, 12 (group A) experienced potentially malignant diseases. The other 20 patients (group B) were previously operated on for oral cancer. In addition, 13 patients showed loss of autofluorescence (8 patients from group A and 5 patients from group B). Among these 13 patients, 12 were affected with lesions of relevance (in group A, 6 had squamocellular carcinoma and 2 had low-grade dysplasia; in group B, 2 patients had high-grade dysplasia, 2 had low-grade dysplasia, and 1 had an epithelial hypertrophy with inflammatory cells). Preliminary results seem to indicate that autofluorescence is a high-performing test for the individuation of oral cancer in populations at risk (sensibility up to 100% and specificity up to 93% in this study).
In mandibular reconstruction with bone grafts, the functional and aesthetic outcomes are clearly influenced by reconstructive techniques. Vascularized free fibular flaps are considered the most suitable choice for mandible reconstruction because of their good aesthetic and functional outcomes. Several techniques have been described in literature. According to various authors, shaping of the fibular graft can be performed by means of computer-aided design/computer-aided modeling procedures for the evaluation of the presurgery anatomy and three-dimensional models of fibula graft. However, these models are expensive, require a strict realization of the programmed intervention, and are not easily adaptable to a surgical treatment different from the planned one. We report our experience on a technique for mandibular reconstruction using a free fibular flap, obtained by modeling a template on the resected mandible. Our operative technique consists of 5 steps: preplating, resection, template modeling, contouring of the fibula, and fixing the flap on the mandible.Template modeling is performed to record the length of the resected bone, the mandibular curvature on the 3 space planes, and the width of the basal bone. On the basis of the template, the fibula flap was modeled while still attached to the pedicle. The plates, positioned at the level of the fibular osteotomies, were preformed to make the fibula precisely fit in the template. Once the fibula was shaped, mandibular reconstruction was completed by positioning the fibula graft on the mandibular stumps. Bone graft modeling by means of template is a rapid, safe, and flexible method to reconstruct the mandible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
