Recently, clinical efficacies of the intraoral balancing appliance therapy have been reported by several researchers, and it has been found that there are various kinds of diseases that can be effectively applied. However, studies on cerebrovascular disease, one of the main diseases with a high mortality rate, are still poorly reported, and studies of temporomandibular joint disorder (TMD)-induced changes in brain function suggest that cerebrovascular disease is more appropriate as an adaptive disorder of the temporomandibular joint (TMJ) balancing device. In the developed countries, the importance of research on the structure and function of the brain has been recognized and spurred on the related research. In Korea, the research on brain function and cognitive disorders should have promoted more massively. In order to regain its former reputation in the Korean medicine in the field of cerebrovascular disease, it should be spurred on basic research and clinical case studies. In addition, extensive and in-depth studies including animal studies are needed to establish the basis of underlying mechanisms of the TMJ balancing therapies.

Septic arthritis of the temporomandibular joint (TMJ) is an uncommon disease caused by microbial pathogens through hematogenous infection, local spread, or iatrogenic infection. As the symptoms have an insidious onset, the early stage of septic arthritis is often confused with other diseases. A 49-year-old man was referred for increasing preauricular pain, swelling, and restricted mouth opening. He had been initially diagnosed as having a conventional temporomandibular joint disorder and trigeminal neuralgia and had been treated for the same. Imaging studies including panoramic view, lateral tomography, computed tomography with contrast enhancement, and magnetic resonance imaging were performed. Erosive bone change with displacement of the involved condyle, diffuse swelling of adjacent soft tissue, and fluid collection in the joint space were noted. Needle aspiration of the joint space and bacterial culture confirmed the diagnosis of septic arthritis of the TMJ and he was treated with antibiotic therapy and surgical drainage. Clinicians should always consider the diagnosis of septic arthritis of the TMJ in patients with preauricular pain or swelling.

Giant cell tumor (GCT) of the craniofacial bones has been reported but they are not common. This tumor occurs more often in women than in men and predominantly affects patients around the third to fifth decade of life. GCTs are generally benign but can be locally aggressive as well. We report a case of GCT involving the temporomandibular joint (TMJ), which was initially thought to be temporomandibular disorder (TMD). A 22-year-old female presented with swelling and pain over the right temporal region for 18 months associated with jaw locking and clicking sounds. On examination, her jaw deviated to the right during opening and there was a $2{\times}2$ cm swelling over the right temporal region. Despite routine treatment for TMD, the swelling increased in size. Computed tomography and magnetic resonance imaging of the brain and TMJ revealed an erosive tumor of the temporal bone involving the TMJ which was displacing the temporal lobe. Surgical excision was done and the tumor removed completely. Histopathological examination was consistent with a GCT. No clinical or radiological recurrence was detected 10 months post-surgery.

Purpose: To evaluate the effectiveness of temporomandibular joint (TMJ) disorder follow-up and determine the factors that affect the TMJ bone scan hot spot numerical value (bone scan value), and to compare this value to the diagnosis of patients with temporomandibular joint disorders (TMD), their treatment options, and the resolution of their symptoms. Materials and Methods: A retrospective cohort study was performed on 24 patients (four males, 20 females) who received TMD treatment in the Section of Dentistry, Seoul National University Bundang Hospital (Seongnam, Korea) from 2007 to 2014. An analysis of the significance test and correlation between TMD diagnosis, treatment options, a baseline the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire, treatment before and after the clinical examination and subjective progress, and TMJ bone scan value change were completed by using SPSS version 12.0. Result: Although only 14 patients had bony factors that caused TMD, the average pre-treatment bone scan value of the all patients was $4.29{\pm}0.31$, which is higher than the finding for osteoarthritis (3.88), and reduced post-treatment bone scan value was found to be without a statistically significant difference (P=0.056). After the treatments, clinical symptoms in 18 patients disappeared, and six patients did not require additional treatment, although they still displayed subjective symptoms. It was observed that the higher the pre-treatment bone scan value, nonspecific physical symptoms, chronic pain index, characteristic pain intensity, disability score, were, the lower the post-treatment bone scan value was. And this reduced post-treatment bone scan value tendency was not shown with the pre-treatment depression index, but there was not a statistical difference. Conclusion: The post-treatment TMJ bone scan value tended to be insignificantly reduced in the 24 patients whose clinical symptoms were improved (P=0.056). Moreover, the TMJ bone scan value showed no relation to the TMD type or its related symptoms.

Nasopharyngeal cancer is malignant tumor of nasopharyngeal area that is characterized of lymphadenopathy, pain, otitis media, hearing loss and cranial nerve palsy and may present symptoms similar to temporomandibular disorder such as facial pain and trismus. In this case, the patient with symptoms similar to temporomandibular disorder after surgery for otitis media presented with facial paresthesia and masticatory muscle weakness. Examinaion of trigemimal nerve was shown sensory and motor abnormaility. The patient was referred to a neurologist. Nasopharyngeal cancer was suspected on computed tomography and magnetic resonance imaging and was confirmed by biopsy. If the patient presenting with paresthesia and muscle weakness the cranial nerve examination should be performed regardless of typical temporomandibular disorder symptom. The neurologic symptom can be caused by neoplasm such as brain tumor and nasopharyngeal cancer. Nasopharyngeal cancer on rosenmuller fossa can develop otitis media. Therefore, the patient with otitis media history should be consulted to otorhinolaryngologist to examin the nasopharyngeal area.

Temporomandibular joint(TMJ) disorders have characteristic clinical findings such as pain, joint sound, and abnormal jaw function. With the rapid progress in TMJ imaging techniques, magnetic resonance imaging(MRI) especially provides the clinician and researcher with the ability to evaluate TMJ disorders(effusion, anterior disk displacement) and the hard and soft tissue of the TMJ. In order to manage the internal derangement of TMJ such as anterior disk displacement, the so-called appliance therapy is commonly used. This technique became the treatment of choice before surgical intervention by many practitioners. The purpose of the present study was to evaluate and determine the efficacy of anterior repositioning splint by means of the change of the position of the disk through pre- and post-treatment MRI. MRI and clinical symptom were carefully recorded in TMJ disorder patients. The relationship between TMJ symptoms such as pain, clicking sound, and disk displacement and effusion in MRI were analyzed. Then, splint therapy was applied for 3 months according to our protocol; at day 1, patients should wear 24 hours, in order to accomodate the splint and then, wearing time is reduced to 12 hours per day for one month. During next 2 months, it is tapered to 8 hours per day according to the evaluation of the clinical symptoms. Post-treatment MRI was obtained after 3 month protocol. This treatment strategy improved the clinical symptoms of TMJ disorder, and effusion and articular disk position showed a significant change. In conclusion, a treatment modality using an anterior repositioning splint therapy is an appropriate method for temporomandibular disorder patients.

Purpose: This study was performed to find the relationship between pain and joint effusion using magnetic resonance imaging (MRI) in temporomandibular disorder (TMD) patients. Materials and Methods: The study subjects included 232 TMD patients. The inclusion criteria in this study were the presence of spontaneous pain or provoked pain on one or both temporomandibular joints (TMJs). The provoked pain was divided into three groups: pain on palpation (G1), pain on mouth opening (G2), and pain on mastication (G3). MRI examinations were performed using a 1.5-T MRI scanner. T1- and T2-weighted images with para-sagittal and para-coronal images were obtained. According to the T2-weighted image findings, the cases of effusions were divided into four groups: normal, mild (E1), moderate (E2), and marked effusion (E3). A statistical analysis was carried out using the $X^2$ test with SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). Results: Spontaneous pain, provoked pain, and both spontaneous and provoked pain were significantly related to joint effusion in TMD patients (p<0.05). However, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ (G1) was not related to joint effusion in TMD patients (p>0.05). Conclusion: Spontaneous pain was related to the MRI findings of joint effusion; however, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ was not related to the MRI findings of joint effusion. These results suggest that joint effusion has a significant influence on the prediction of TMJ pain.

Perforation of articular disc of temporomandibular joint is a unusual condition and diagnosed through magnetic resonance imaging (MRI), arthrography or arthroscopic surgery. We attempted to investigate the suspicious findings of articular disc perforation through examination commonly used in temporomandibular disorder (TMD) patients. We retrospectively analyzed the clinical and imaging findings of five TMD patients whose articular discs were perforated based on MRI. The most meaningful finding was the abnormal width of the joint space in cone-beam computed tomography. Thus, the clinician should perform a thorough assessment of the joint space in TMD patients and conduct additional investigation to determine what caused the abnormal joint space.

As for temporomandibular joint arthritis (TMJ OA), managing the contributing factors at an early stage through accurate diagnosis is necessary to prevent irreversible bone changes. TMJ OA, which is a multi-organ disease caused by various pathophysiological mechanisms, is developed mainly due to mechanical overload. It is a disease characterized by degeneration of articular cartilage and subchondral bone as a low-level inflammatory arthritis condition developed by dysregulation of catabolic and anabolic activity of chondrocytes. Age, mechanical overload sensing of cartilage, chondrocyte apoptosis, catabolic enzymes, inflammatory factors, abnormal remodeling of subchondral bone, and estrogens may be involved in the pathogenesis of arthritis. Therefore, a comprehensive evaluation is needed to diagnose and manage progressive cartilage degeneration, subchondral bone remodeling, and associated symptoms of TMJ OA.
