BACKGROUND The increased prevalence of temporomandibular disorders (TMDs) requires searching for new, easily accessible diagnostic methods. In addition to routine clinical examination, various methods of imaging temporomandibular joints are available, such as magnetic resonance imaging, computed tomography scans, or scintigraphy. Ultrasound imaging, due to short examination time, low cost, and non-invasiveness, should be recommended as a routine diagnostic procedure. The aim of the study was to investigate whether ultrasound imaging can be used in the diagnosis of temporomandibular joint disorders...

PURPOSE: Arthrocentesis is an effective treatment modality for temporomandibular disorders, especially in patients who have pain and limited mouth opening. Surgeons generally suggest physical exercises after arthrocentesis and arthroscopy procedures; however, there has been no study in the literature evaluating the effects of exercise on clinical outcomes. This study investigated whether physical exercises after arthrocentesis would result in early improvements in clinical symptoms in patients with temporomandibular joint disc displacement without reduction (TMJ DDw/oR)...

Effusions are common among patients with disorders of the temporomandibular joint (TMJ), but publications are limited and results inconsistent about the correlation between them and important clinical variables, in particular severity of pain and degenerative disease. We organised a retrospective study of patients who presented for the evaluation and management of arthralgia of the TMJ and myofascial pain at the University of Michigan between 2011 and 2014. Inclusion criteria were: patients who had pain that was primarily arthrogenous, and coexisting myogenous pain, who had had initial non-surgical treatment, and arthroscopy of the TMJ with or without intramuscular injection of onabotulinumtoxinA (Botox,® Allegan, Weston, Fl, USA)...

Objectives: Headache is the most common complaint of patients suffering from temporomandibular joint disorders (TMDs). Thus, temporomandibular joint (TMJ) examinations maybe necessary in patients with headache. Considering the high prevalence of bruxism and TMDs in patients with headache the effects of conservative TMD treatment on headache should be assessed. Materials and Methods: Patients were questioned about headaches in the past three months. Those responding affirmatively to this question were examined for TMD and bruxism...

INTRODUCTION: Correction of severe malocclusions with skeletal discrepancies requires orthodontic treatment in combination with orthognathic surgery. Even though conventional orthognathic surgery (COS) is a common and well-accepted approach its influence on the signs and symptoms of temporomandibular disorders (TMDs) is still debated. Recently with the introduction of surgery first approach, a different timing for the management of dentoskeletal imbalances has been proposed. The present study is aimed at assessing the relationship between surgery first approach and temporomandibular joint (TMJ) disorders...

Conservative approach, including occlusal splint therapy, is the first option to treat temporomandibular disorders (TMD), because of its reversibility. The present study analyzed the effect of the articular disc position and occlusal splints use on the stress distribution on this disc. A two-dimensional (2D) finite element (FE) model of the temporomandibular joint with the articular disc at its physiologic position was constructed based on cone-beam computed tomography. Three other FE models were created changing the disc position, according to occlusal splint use and anterior disc displacement condition...

Tenosynovial giant cell tumor of diffuse type (TGCT-d) or pigmented villonodular synovitis (PVNS) is a locally aggressive lesion that mostly affects the joints of long bones. Chondroid tenosynovial giant cell tumor (CTGCT) or PVNS with chondroid metaplasia is a rare distinct subset of synovial tumors that has a predilection for the TMJ. We report a rare case of CTGCT in the TMJ, initially misdiagnosed as temporomandibular disorder (TMD). A 51-year-old woman was referred to the surgeon with the chief complaint of TMJ pain for 5 years and a past history of an unsuccessful TMD treatment...
