Inflammation and damage in the temporomandibular joint (TMJ) often develop without clinical symptoms but can lead to severe facial growth abnormalities and impaired health-related quality of life, making early diagnosis of TMJ changes crucial to identify. Inflammatory and osteochondral changes detectable through magnetic resonance imaging (MRI) occur in TMJs of approximately 40% of children with juvenile idiopathic arthritis (JIA), and no other imaging modality or physical method of examination can reliably detect these changes...

Nodular tenosynovitis usually affects the hands and it represents a benign pathology with locally aggressive behavior. Its etiology could be related to chronic inflammatory processes such as trauma, metabolic disturbance, and joint diseases. Histopathological analysis is required for a diagnosis of certainty and surgery represents the treatment of choice. There are no cases in the literature that describe a nodular tenosynovitis affecting the temporomandibular joint (TMJ) The main aim of the present report therefore, is to describe this unusual case and to show the utility of arthroscopic procedures in managing intra-articular tumors of the TMJ...

Dystonia affecting the perioral and pharyngeal regions is called oromandibular dystonia (OMD). OMD can affect the jaw muscles and may cause trismus, mouth-closing disturbance, tooth wear/loss, and damage to the oral soft tissues and temporomandibular joint (TMJ). This case history reports a case of jaw-closing OMD accompanied by trismus-related TMJ osteoarthritis (OA). In the present case history, treatment for OMD was started as soon as the diagnosis of jaw-closing OMD was established, and dental treatment intervention for preventing its development or progression was considered at the same time...

Background Ganglion cysts in the temporomandibular joint are treated by resection; however, there has been insufficient discussion regarding the appropriate approach for surgical resection. Clinical presentation A 55-year-old man presented with a left preauricular swelling for one year. The examination revealed a moderately hard mass with a 30-mm diameter, tenderness, and restricted movement. Magnetic resonance imaging showed a cystic lesion with a 25 mm-long axis. Considering a diagnosis of temporomandibular cyst, separation of the cyst wall through a preauricular incision was attempted...

There is a direct relationship between the prevalence of musculoskeletal disorders of the temporomandibular joint and orofacial disorders. A well-elaborated analysis of the jaw movements provides relevant information for healthcare professionals to conclude their diagnosis. Different approaches have been explored to track jaw movements such that the mastication analysis is getting less subjective; however, all methods are still highly subjective, and the quality of the assessments depends much on the experience of the health professional...

Organized hematoma is a pseudo-tumorous lesion mostly occurs at sinonasal cavity and often confused with malignant neoplasm. The initiation of this lesion is blood accumulation, probably due to trauma, and this hematoma develops into organized hematoma as it encapsulated with fibrous band and neo-vascularized. Since it is uninformed at temporomandibular joint (TMJ) region, imaging diagnosis might be challenging. Also, delayed detection of mass involving TMJ is not uncommon due to confusion with joint disorder...
