Introduction : Patients with temporomandibular disorder may have various ear-related symptoms. If an excessive load is applied to the ear area due to the skeletal shape of the mandibular condyle or malposition of the disc, an auditory problems may occur. Case report : The patient was referred to our clinic due to the suspicion of temporomandibular disorder from the local otorhinolaryngology clinic. A few days ago, his right ear could not be heard. MRI showed that the left TMJ disc was anterior displacement with reduction, the right TMJ disc was anteromedial displacement without reduction. Also Right mandibular condyle showed sclerotic bone change, subchondral cyst and was compressing the frontal wall of the ear on MRI view. Right TMJ arthroplasty was done under the diagnosis of right TMJ osteoarthritis and osteochondroma. Postoperative intermaxillary fixation was done with SAS screw and elastics for 2 weeks. One month after the operation, hearing and TMJ discomfort were recovered without any complications. Conclusions As seen in this case, hearing loss due to benign tumor-like lesions of the temporomandibular joint should be treated surgically to restore the TMJ function and hearing.

TMJ ankylosis is defined as a mobile disorder of jaw such as mouth opening limitation, limitation of anterior or/and lateral movement of TMJ. Kazanjian published first clinical report about classification of TMJ ankylosis dividing with intracapsular ankylosis and extracapsular ankylosis. TMJ ankylosis is resulted from trauma, infection, metastatic tumor, irradiation, burn and etc. When TMJ ankylosis is manifested in growing period, it affects to functional disorder and development and position of mandible, so it can result in maxillofacial deformity such as facial asymmetry, micrognathia, malocclusion. For treatment of TMJ ankylosis, various surgical interventions were devised ; condylectomy, gap arthroplasty, interpositional arthroplasty and TMJ reconstruction. So, we report our results with documental study and cases of true ankylosis in our department.

Synovial chondromatosis (SC) is an uncommon progressive cartilaginous metaplasia of residual mesenchymal cells in synovial tissue. This disorder usually affects large joints and is rarely observed in the temporomandibular joint (TMJ). SC in TMJ is difficult to diagnose early owing to non-specific clinical symptoms. In this article, we report a patient with SC on the right TMJ, who presented with pain in the right TMJ and progressive occlusal changes, not responsive to conventional conservative temporomandibular disorder treatment for several months. This case emphasizes the importance of an accurate specific diagnosis for TMJ problems before the delivery of any treatment.

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.

Epidermoid cyst in bony wall of external auditory canal (EAC) is a very rare pathologic condition. In addition to its extreme rarity, its positional proximity to temporomandibular joint (TMJ) might lead to clinical misdiagnosis as TMJ disorders, especially when it is accompanied by temporomandibular disorders-like symptoms. In this article, we report a patient with epidermoid cyst in anterior bony wall of EAC, which was misdiagnosed as TMJ disorder because the left TMJ pain aggravated during mastication.

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.

Background: In the treatment of temporomandibular joint (TMJ) disorder, the goals of traditional physical therapy are not only to reduce the inflammatory process leading to pain, but also to decrease joint overload and muscle hyperactivity. To achieve those goals, physical therapists generally use a photo-therapy, joint mobilization, and massage. Objects: To examine the impact of an unloading technique using non-elastic taping on the pain, opening mouth, functional level, and quality of life in patients with TMJ disorder. Method: Twenty patients with TMJ disorder were included in this study and randomly divided into the experimental ($n_1$=10), and control ($n_2$=10) groups. Traditional physical therapy including massage and stretching for 30 min was performed in both groups. Non-elastic taping was performed in the experimental group after traditional physical therapy, and they were recommended to keep the tape attached for 12 hours. Outcomes for pain, functional level, and quality of life were measured using a survey. The opening mouth was measured using a general ruler. Result: Significant differences were observed in the pain level, opening mouth, functional level, and quality of life after the intervention and on follow-up in both groups. However, we found that while the levels of all parameters were maintained throughout the follow-up period in the experimental group, the functional status level was not maintained throughout the follow-up period in the control group. Conclusion: Our unloading technique using non-elastic tape results comparable to those achieved by traditional physical therapy in the treatment of TMJ. However, the unloading taping method using non-elastic tape is more effective than traditional physical therapy in maintaining the impact of intervention.

Objective: The aim of this study is to investigate whether patients with temporomandibular disorder have more anxiety than normal people. Methods: Patients group(n=50) with TMD and normal group(n=30) without TMD and other disease completed STAl(State-Trait Anxiety Inventory), and there was comparison of mean scores between patients and normal groups. Results: The mean of total STAl scores of patients group was $91.32{\pm}20.32$, whereas that of normal group was $81.27{\pm}12.97(p<0.01)$. The mean of state-anxiety scores of patients group was $45.68{\pm}11.30$, whereas that of normal group was $40.70{\pm}7.28(p<0.05)$. The mean of trait-anxiety scores of patients group was $45.64{\pm}10.02$, whereas that of normal group was $40.57{\pm}7.22(p<0.05)$. There was a tendency that patients with TMD had more anxiety. So, doctors had better give attention to patients' anxiety when they treat the patients with TMD.
