Computed tomography and computer-aided design for locating available palatal bone for grafting: two case reports.

Autologous bone graft is considered the gold standard for oral and maxillofacial rehabilitation. The purpose of these case reports is to present the palate as a donor site in the oral and maxillofacial region. A surgical technique of palatal bone grafting with computer-aided design is proposed. Computed tomography and three-dimensional study with a software program (Simplant) were used to evaluate bone quality and quantity at the palatal donor site and also provide a preoperative planning tool for placement of implants. This software was also used to determine the amount of bone needed for the implant site. A palatal marginal incision was made and a full-thickness flap was elevated from the central incisor region to the premolar region. A bone trephine was used to harvest corticocancellous palatal blocks. No swelling or hematomas were found at any donor sites. Simplant software can map the bone within a defined palatal area and provide important information about the quality and quantity of bone in the donor area.

Autosomal dominant osteopetrosis and maxillomandibular osteomyelitis.

Osteopetroses represent a heterogeneous group of rare, hereditary bony dysplasias. They range from a devastating neurometabolic disease (including severe malignant infantile osteopetrosis) to 2 more benign conditions principally affecting adults: autosomal dominant osteopetrosis (ADO) type I and type II. The present study describes the maxillofacial manifestations associated with the 2 subgroups of ADO. In this paper, we present the oldest patient described in the literature with ADO type I (76 years old). We also document the first ADO type II patient described in the literature with synchronic osteomyelitis of the mandible and the maxilla.

Metástasis mandibular por carcinoma hepático: un infrecuente caso con severa hemorragia / Hepatocellular carcinoma metastatic to the mandible: a case involving severe hemorrhage

El carcinoma hepatocelular (CH) es relativamente infrecuente en Europa y Estados Unidos, a pesar de que en este último país se diagnostican más de 13.000 nuevos casos cada año. Las metástasis mandibulares por CH son inusuales, recogiéndose en la literatura hasta el momento, 50 casos. En el presente trabajo se documenta un nuevo caso, correspondiente a un varón de 54 años que presentó una metástasis por HC en el cuerpo mandibular derecho, al año del tratamiento de su tumor primario. El curetaje-biopsia de la lesión se acompañó de una profusa hemorragia. El paciente falleció a los seis meses de la biopsia, con múltiples metástasis. Se describen las posibles vías de diseminación hematógena de la enfermedad (AU)

Hepatocellular carcinoma (HCC) is quite uncommon in Europe and USA, although in this last country more than 13,000 new cases are diagnosed every year. Mandibular metastases are unusual, with only 50 cases documented. In this article, we present a 54 year-old male patient with a metastasis of HCC in right mandibular body, one year after treating the primary tumor. Curettage and biopsy of the lesion was performed, followed by a profuse hemorrhage. The patient expired six months after the biopsy, with multiple metastases. We describe the different paths for hematogenic dissemination of the process (AU)
