Intraosseous haemangioma are rare, benign tumours, and only rarely do they involve the facial bones. We present a singular case of zygomatic intraosseous haemangioma treated surgically and reconstructed with a methyl-methacrylate alloplastic prosthesis designed from a computed tomography (CT)-based 3D model. This is the first case described in the literature of a zygomatic reconstruction with a predesigned prosthesis. After 1 year of follow-up, aesthetical results are good, and the patient presents correct functional rehabilitation., (Copyright (c) 2009 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

The anterior iliac crest is the most common donor site for autologous nonvascularized bone because of the great amount of bone available and easy access. Documented donor-site complications include arterial, nerve, or urethral injury; herniation; chronic donor-site pain; sacroiliac joint instability; pelvic fractures; gait disturbances; hematoma; infection; peritoneal perforation; cosmetic defects; and hip subluxation. We present the case of a pathologic fracture of the right anterior iliac crest during the immediate postoperative period in a patient with a bisphosphonate-related osteochemonecrosis with pathological fracture of mandibular body. The patient was managed with nonoperative treatment.

Pleomorphic adenoma (PA), originally called mixed tumour, is the most common neoplasm of the salivary glands and is generally accepted as benign biologically. Occasionally PA may give rise to metastasis. The metastasis may develop in a PA in which a malignant transformation occurs, either arising a carcinoma in the PA (carcinoma ex-mixed tumour) or as a carcinosarcoma (so-called true malignant mixed tumour). However, very rare benign PA eventually metastasise, usually after having a previous recurrence, displaying benign histological features as well in the primary tumour as in the metastasis. These tumours have been termed metastatic PA or metastatic mixed tumours. The aim of this paper is to report one case of metastatic histological benign pleomorphic adenoma, and to consider the clinical, pathological and therapeutic consequences of these rare tumours as well as its possible causes and mechanisms for its behaviour.

Purpose: This study compared the complication rate with different types of mandibular fracture treatment (maxillomandibular fixation, 2-mm miniplates, 2.4-mm AO plates, and 2.7-mm AO plates)., Patients and Methods: A total of 245 patients who presented with 386 fractures were retrospectively analyzed. Patient characteristics, type of fracture, severity of fracture, type of treatment used, and occurrence of complications were recorded. Statistical analysis was used to compare complication rates, fracture severity, and type of treatment., Results: There were no differences in the complication rates for the different types of treatment. There was a significant correlation (P < .05) between fracture severity and the overall complication rate, postoperative infection, and postoperative malocclusion, but there was no significant correlation between these complications and the type of treatment applied., Conclusion: The occurrence of postoperative complications in the treatment of mandibular fractures is fundamentally related to the severity of the fracture rather than to the type of treatment used.
