Whether a patient with head and neck cancer has mandibular invasion or not is important in determining the method of resection surgery. But, no modality is adequately reliable when used alone in the evaluation of mandibular invasion. Therefore, to more accurately diagnose mandibular invasion in head and neck cancer, we used a new modality, namely, 99mTc methylene diphosphonate (MDP) or 99mTc hy...
BACKGROUND The number of elderly patients with maxillofacial trauma is rapidly increasing due to active lifestyles and longevity. Shimane prefecture has the fastest growing proportion of elderly individuals in Japan. The aim of this study was to reveal the distinctive features and treatment modes of mandibular fracture treatment mode in patients requiring hospitalization at the Department of Or...
Arthrogryposis Multiplex Congenita is a condition characterized by multiple contractures of the joints. Involvement of the temporomandibular joint is a common complication that limits mandibular opening. A case of Arthrogryposis Multiplex Congenita with anterior open bite and limited maximal incisal opening is presented. Orthognathic surgery, consisting of segmental LeFort I osteotomy and bilat...
As a continuation of the previous study on palate development (Rot and Kablar, 2013), here we explore the relationship between the secondary cartilage mandibular condyles (parts of the temporomandibular joint) and the contributions (mechanical and secretory) from the adjacent skeletal musculature. Previous analysis of Myf5-/-:MyoD-/- mouse fetuses lacking skeletal muscle demonstrated the import...
Maxillofacial trauma in cats often results in mandibular symphyseal separation in addition to injuries of the caudal mandible and/or temporomandibular joint (TMJ). Caudal mandibular and TMJ injuries are difficult to access and stabilize using direct fixation techniques, thus indirect fixation is commonly employed. The immediate goals of fixation include stabilization for return to normal occlus...
BACKGROUND Mandibular reconstruction is performed after segmental mandibulectomy, and precise repositioning of the condylar head in the temporomandibular fossa is essential for maintaining preoperative occlusion. METHODS In cases without involvement of soft tissue around the mandibular bone, the autopolymer resin in a soft state is pressed against the lower border of the mandible and buccal a...
PURPOSE To investigate whether MR imaging is an accurate means of assessing mandibular invasion in patients with carcinoma. METHODS We retrospectively studied the MR scans of 22 patients with pathologic or surgical confirmation of mandibular invasion from oral and oropharyngeal cancers. The MR images were blindly analyzed using primary criteria of: (a) cortical breakdown, (b) replacement of b...
The authors report a rare association case of juvenile idiopathic arthritis (JIA) and osteogenesis imperfecta (OI) in a 53 years-old female patient, present a literature review and discuss the radiological aspects of the temporo-mandibular joint involvement. To our knowledge, this is the first case report of JIA an OI association.
Condylar intramedullary intraosseous lipoma: Contribution of a new case and review of the literature
BACKGROUND Lipoma is the most common benign tumour of the human body, being intraosseous involvement very rare. Just 1 to 4% of all cases of lipoma are located in the oral cavity, only 0.1% being intraosseous. The jaw is its most uncommon bone location. Etiology of intraosseous lipoma (IOL) is unknown, although several theories have been proposed. Usually asymptomatic, the symptoms, when presen...
OBJECTIVES To systematize the clinico-radiological symptoms and course of bisphosphonate-related osteonecrosis of jaw bone and toevaluate the diagnostic potential of various radiological techniques to detect mild osteonecrosis in each stage of the disease. MATERIAL AND METHODS The sample consisted of 22 patients previously diagnosed with extraoral malignant disease. Diagnosis was based on a c...
