BACKGROUND: Patients with any type of temporomandibular disorder (TMD) may have several symptoms in their temporomandibular joints, masticatory muscles and associated structures, and may have otological symptoms such as tinnitus, ear fullness, ear pain, hearing loss, hyperacusis, and vertigo, which may be due to the anatomical proximity between the temporomandibular joint, muscles innervated by the trigeminal nerve, and ear structures. Objective: This study found a prevalence of ear complaints described in the medical records of patients (n = 485) at the Center for Diagnosis and Treatment of the Temporomandibular Joint and Dental-Facial Functional Alterations at Tuiuti University of Paraná (CDATM/UTP), with TMD evaluated by the Research Diagnostic Criteria/Temporomandibular Disorders (RDC/ TMD)...

Background Clinical assessments and uniplanar images in temporomandibular disorders are not always entirely reliable. This predicament is especially important when clinicians need to determine the nature of temporomandibular joint disease, particularly when clinical features are not helpful in determining the diagnosis. Clinical presentation A 63-year-old female patient presented with mild pain in her right TMJ. During routine imaging exams, a destructive monoarticular arthritis was noticed, producing multiple erosions of the mandibular and temporal condyles...

Patients with hypermobility disorders of the jaw joint experience joint sounds and jerky movements of the jaw. In severe cases, a subluxation or luxation can occur. Clinically, hypermobility disorders should be differentiated from disc displacements. With biomechanical modeling, we previously identified the anterior slope angle of the eminence and the orientation of the jaw closers to potentially contribute to hypermobility disorders. Using cone-beam computed tomography (CBCT), we constructed patient-specific models of the masticatory system to incorporate these aspects...

INTRODUCTION: Extraskeletal or soft-tissue chondroma is a rare benign cartilaginous neoplasm which usually affects hands and feet. Scientific literature only reports one previous case of this pathology in the preauricular region. PRESENTATION OF THE CASE: This report describes a rare case of extraskeletal chondroma surrounding the temporomandibular joint of a 55-year-old female patient. DISCUSSION AND CONCLUSION: Diagnosis of extraskeletal chondroma is challenging since tissue swelling, diagnostic imaging and even histopathological features may be misleading for other joint or gland pathologies...

The etiology of degenerative processes of the temporomandibular joint (TMJ) remains unclear, as they could be the result of trauma, infection, or autoimmune disease. Improving the diagnosis of autoimmune disease, whether the TMJ is the primary site or secondarily affected by a systemic disease, is of fundamental importance in selecting treatment that will address the causes rather than just relieve the symptoms. The purposes of this article are to discuss autoimmunity as an etiologic factor in degenerative processes of the TMJ by presenting clinical cases and to highlight the importance of imaging and serologic examinations for diagnosis...

The objective of this study was to determine the diagnostic accuracy of panoramic radiography and magnetic resonance imaging (MRI) for detection of signs of temporomandibular joint (TMJ) degenerative joint disease (DJD). Panoramic radiography and bilateral MRI and computed tomography (CT) of the TMJs were performed for 705 subjects. Three calibrated board-certified radiologists who were blinded to the clinical findings interpreted all images. The diagnoses of DJD established using the panoramic radiographs and MRIs were compared to the reference standard diagnoses derived from the CTs...

Synovial chondromatosis is a rare metaplastic disease affecting the joints, including the temporomandibular joint (TMJ). Since its symptoms are similar to those of temporomandibular disorders, a careful differential diagnosis is essential. A 50-year-old male patient was referred with the chief complaint of pain and radiopaque masses around the left TMJ on panoramic radiography. Clinically, pre-auricular swelling and resting pain was found, without limitation of mouth opening. On cone-beam computed tomographic images, multiple calcified nodules adjacent to the TMJ and bone proliferation with sclerosis at the articular fossa and eminence were found...

Temporomandibular joint (TMJ) ankylosis is fusion or a bony union of the head of the condyle and the glenoid fossa by bony or fibrotic tissues. Due to the immobility of the TMJ, all mandibular movements get affected. Treatment goals are to allow nearly normal TMJ movements, restore symmetry of the face and occlusion, and promote growth and correction of deformity in children. The surgical techniques used to treat TMJ ankylosis are a gap or interpositional arthroplasty, joint reconstruction, and distraction osteogenesis...

Septic arthritis of the temporomandibular joint (TMJ) is rare, but patients with this diagnosis are at high risk for significant morbidity. We present a case of a 15-year-old man who presented with increasing trismus for 3 days. He had only minimal discomfort and swelling of the right cheek and temporal region, and pericoronitis of an impacted wisdom tooth was suspected. Under intravenous antibiotics, pain subsided, but trismus and a slight swelling remained. CT scan showed septic arthritis of the TMJ with an abscess formation penetrating into the epidural space...

Temporomandibular joint (TMJ) dislocation is a common occurrence, but diagnosis can be missed if patients do not complain. Delayed presentation complicates the management of a straightforward reduction. We present a case of a 24-year-old man who had bilateral TMJ dislocation of unknown duration after motor vehicle accident. The accident left him bedridden with speech difficulty. He was totally dependent on Ryles' and percutaneous endoscopic gastrotomy tubes for feeding. Computed tomography revealed dislocation of condyles anterior to articular eminences...

Rhinologic and oral maxillofacial complications from scuba diving are common, representing approximately 35% of head and neck pathology related to diving. We performed a systematic and comprehensive literature review on the pathophysiology, diagnosis, and treatment of rhinologic and oral maxillofacial pathology related to diving. This included complications due to sinus barotrauma, barodontalgia, odontocrexis, temporomandibular joint dysfunction, partially dentulous patients, and considerations for patients following major head and neck surgery...

Intra-Articular Temporo-Mandibular Disorders (TMD) are characterized by displacement of the disc that causes the condyles to slip back over the disc thus resulting in TMJ discal damage and erosion of the condyle's bone. The etiology of temporomandibular disorder (TMD) is multidimensional: biomechanical, neuromuscular, bio-psychosocial and biological factors may contribute to the disorder. The study involved 46 joints in 27 patients with a diagnosis of Intra-Articular Temporo-Mandibular Disorders (TMD) according to Axis I of Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for Clinical and Research Applications and underwent surgery between 2011 and 2014...

Patients with internal derangement of the temporomandibular joint and dentofacial deformities need appropriate evaluation for both conditions. Correct diagnosis of internal derangement is vital in determining the correct orthognathic surgery plan, and it is particularly important to differentiate between myofascial dysfunction and intra-articular joint problems. Depending on the stage of internal derangement, patients may need treatment for temporomandibular dysfunction symptomatically, staged, or concurrently with orthognathic surgery...

Diagnostic imaging is sometimes necessary to supplement the clinical findings in patients with suspected temporomandibular disorders (TMDs). However, the interpretation of pathology in the imaging findings is often complicated by the presence of similar findings in asymptomatic volunteers, as well as by the use of inadequate imaging techniques and poor image quality. This article focuses on these issues and gives guidance on the appropriate use of diagnostic imaging in patients with suspected TMD.

There has been considerable progress in the identification of the various synovial fluid cytokines and growth factors associated with various disorders of the temporomandibular joint. However, the presence of the same inflammatory mediators and proteins in these conditions, despite differing causes, makes it very difficult to identify the specific disease using synovial fluid analysis alone.
