Maxillofacial prosthesis (MFP) can be defined as the art and science of esthetic and functional reconstruction of the facial bones, art because it uses hand-crafted and empirical rules, science because of its technical rigorism and its integration in medicine. MFP aims to multidisciplinary rehabilitate patients presenting with cutaneous and underlying structures defects, It also allows for functional speech and swallowing rehabilitation related to temporo-mandibular joint disorders. Whatever the origin, (traumatic, infectious ortumoral), surgical treatment of these TMJ disorders is usually not indicated in first-line...

Extragnathic xanthomas are seen in the bones or as soft tissue masses. They are often associated with hyperlipidemia and are considered as reactive or metabolic lesions. Only 19 cases of xanthomas of the jaws have been reported so far in the English literature. A total of ten cases of central xanthoma of the jaw bones were identified from the Oral and Maxillofacial Pathology biopsy services of the University of Washington and the Tufts University School of Dental Medicine, between the years 2000-2016. The demographic and clinical information on these cases was tabulated logically on the basis of age, gender, location and presence or absence of symptoms, extragnathic lesions and serum hyperlipidemia...

INTRODUCTION: The temporomandibular joint is highly adaptive and masticatory apparatus disorders (MAD) can occur when its ability to adapt is overwhelmed. Occlusal etiologies were long pinpointed as the sole culprits. However, a consensus now exists which minimizes their involvement. It is recognized that the etiology of MAD is multifactorial, combining occlusal problems, parafunctions, postural anomalies, orofacial dyspraxia and stress. MATERIALS AND METHODS: In this article, the authors review the role of physiotherapy in managing these pathologies...

BACKGROUND: The temporomandibular joint (TMJ) dislocation can be categorised into three groups: acute, habitual or recurrent and long-standing. The long-standing or protracted lower jaw dislocation refers to a condition that persists for more than one month without reduction. There are a great variety of methods for its treatment, from the manual or non-surgical, to surgical ones like the indirect approach (conservative surgical approach) and direct approach (open joint). Additional procedures in unsuccessful cases may include extra-articular orthognathic techniques to correct a malocclusion until joint replacement...

Pathological conditions can give rise to calcifications within oral mucosa representing either a local or systemic disturbance. Inflammation, trauma, debris acting as nidus and vascular lesions have been attributed as principal causes for occurrence of calcifications within the oral mucosa. Occurrence of multiple calcified thrombi (phleboliths) is considered pathognomonic for hemangiomas and vascular malformations in the oral and maxillofacial region. Isolated occurrence of phlebolith in oral mucosa though very rare, especially without any underlying vascular lesions, can be diagnostically challenging...

Background. The inferior alveolar canal should be examined as a significant anatomical landmark, particularly in the posterior body and ramus of the mandible, for dental and surgical procedures. In the present study, the effects of two pathological lesions, ameloblastoma and keratocystic odontogenic tumor, on canal displacement were investigated. Methods. This study had a single-blinded design. Twenty-six patients with lesions in the mandible referred to Imam Reza Hospital, Tabriz, Iran, were studied in two equal groups (13 patients with a histopathological diagnosis of ameloblastoma and 13 with a histopathological diagnosis of odontogenic keratocyst)...

This study describes a case of myxoid chondrosarcoma of the mandible in a 22-year-old male patient. A tumour in the buccal gingiva of the lower left premolar region had been identified 2 years earlier. Whole-jaw panoramic radiographs showed a hypodense shadow in the mesiodistal area near the roots of teeth 34 and 35. A maxillofacial computed tomography scan revealed a mass in the lower left premolar soft tissue, with a shadow indicating bone destruction, a clear boundary and uniform density. The preliminary diagnosis at the outpatient department was 34-35 epulis...

Low-grade fibromyxoid sarcoma (LGFMS) is a distinctive variant of fibrosarcoma with a high metastasizing potential and is characterized by a long interval between tumor presentation and metastasis. LGFMS involving the maxillofacial region is a very rare entity with only six cases reported till date. LGFMS is characterized by its benign histological appearance, with spindle cells in whorling pattern, and collagenized and myxoid areas. The heterogeneous histological appearance makes the diagnosis challenging...

C R Wirtz
Intraoperative navigation systems are widely used in ENT, oral and maxillofacial, and neurosurgery. The benefits of such systems have been demonstrated in various applications, including intracranial and skull base surgery. Intraoperative shift, "brain shift" and changes in anatomy caused by the surgical procedure itself impair the accuracy of navigation and represent factors limiting its application, particularly in glioma and metastatic brain surgery. For this reason, intraoperative imaging was incorporated into neurosurgery...
