Total condylar resorption and the failure of bone synthesis material as postoperative complications of condyle fracture are seldom reported in the literature. When these occur, they may severely limit temporomandibular joint (TMJ) function. In such cases, a reconstruction of the joint is indicated, which can be achieved by means of an alloplastic prosthesis. This article reports a rare case of impaction of osteosynthesis material in the region of the base of the skull associated with a mandibular condyle fracture treated with rigid internal fixation, which resulted in complications. There was progression to condylar resorption, requiring an alloplastic TMJ reconstruction, which was performed in a single surgical session.

The lateral pterygoid muscle (LPM), a critical component of the masticatory muscles, typically comprises upper (SLPM) and lower (ILPM) heads. However, it is essential to note that the LPM's structure is not a constant feature, as the number of bundles and their topography can vary. Moreover, additional heads, such as medial and middle heads, and unique-headed configurations of the LPM have been reported.

The objective of this study was to compare single-needle arthrocentesis with the conventional two-needle arthrocentesis, as well as the additional intracapsular injection of hyaluronic acid or platelet-rich fibrin. A total of 96 patients with established osteoarthritis (OA) ( = 48) or with internal de-arrangement (DD) ( = 48) were assigned single-needle arthrocentesis with distension of the joint or conventional two-needle arthrocentesis with or without intracapsular injection of the medication (hyaluronic acid (HA) or platelet-rich plasma (PRP)) performed every month over a period of 6 months. The maximum mouth opening and pain, as measured by the visual analog scale (VAS), were compared.

Background: The accurate diagnosis of degenerative joint diseases (DJDs) of the temporomandibular joint (TMJ) presents a significant clinical challenge due to their progressive nature and the complexity of associated structural changes. These conditions, characterized by cartilage degradation, subchondral bone remodeling, and eventual joint dysfunction, necessitate reliable and efficient imaging techniques for early detection and effective management. Cone-beam computed tomography (CBCT) is widely regarded as the gold standard for evaluating osseous changes in the TMJ, offering detailed visualization of bony structures.

Temporomandibular joint osteoarthritis (TMJ-OA) is a common disease often accompanied by pain, seriously affecting physical and mental health of patients. Abnormal innervation at the osteochondral junction has been considered as a predominant origin of arthralgia, while the specific mechanism mediating pain remains unclear. To investigate the underlying mechanism of TMJ-OA pain, an abnormal joint loading model was used to induce TMJ-OA pain.

Involvement of the temporomandibular joint (TMJ) in patients with juvenile idiopathic arthritis (JIA) has been increasingly reported, affecting up to 87% of cases. This involvement generally occurs after the diagnosis of JIA has been established; however, in the authors' cases, as in a few others documented in the literature, patients presented with isolated TMJ arthritis as the sole joint involvement. The authors performed a narrative literature review on TMJ involvement in JIA and reported 2 cases that presented with isolated TMJ arthritis as the initial manifestation of JIA.
