Purpose: To observe the relationship of bilaminar zone of temporomandibular joint retrodiscal tissues to the disc condition. Materials and Methods : The upper and lower stratum of bilaminar zone were identified on magnetic resonance open mouth images of 148 joints from 74 patients with disc displacements. Results: Both strata were identifiable in 105 joints which had disc displacement with reduction. Lower stratum was not identifiable in 35 joints which had disc displacement without reduction but 12 of 35 had hyalinized posterior attachment where the disc was. The 8 joints which had partial disc displacement without reduction showed identifiable lower stratum at the reducing site which was medial. Conclusion: Disruption or no identification of lower stratum which corresponds to the condylar portion of posterior attachment may be the sign of disc displacement without reduction.

Purpose: The purpose of this study was to evaluate the correlation between the clinical symptoms of temporomandibular disorder and findings in the magnetic resonance imaging (MRI). Materials and Methods: Clinical data and MRI images were collected from a total of 240 German patients. Clinical symptoms were briefed as joint clicking, crepitus and pain. MRI findings were further defined according to the condyle position, condyle degeneration, disc positon, disc degeneration and the presence of osteophyte/sclerosis/synovitis. Hypermobility was separately recorded. Correlation analysis between parameters was performed. Result: Joint clicking had a positive correlation with unilateral disc degeneration, osteophyte, sclerosis and synovitis. Crepitus had a significant correlation with bilateral osteophyte. Pain was not correlated with any MRI findings except hypermobility. Conclusion: Selective correlations between the MRI findings and clinical symptoms were elucidated. The results of this study imply that condyle-disc deformities could be advanced without pain, and that joint clicking and crepitus could be clinical symptoms of condyle-disc degeneration.

Headaches are one of the most common conditions associated with temporomandibular disorder (TMD). In the present paper, we evaluated the relationship between headache and TMD, determined whether headache influences the symptoms of TMD, and reported two cases of TMD accompanied by headache. Our practical experience and a review of the literature suggested that headache increases the frequency and intensity of pain parameters, thus complicating dysfunctional diseases in both diagnostic and treatment phases. Therefore, early and multidisciplinary treatment of TMD is necessary to avoid the overlap of painful events that could result in pain chronicity.

Purpose: To evaluate the relationship between internal derangement and osteoarthrosis in the temporomandibular joint (TMJ) using magnetic resonance imaging (MRI). Materials and Methods: One hundred and six MR images of TMJs in 53 patients were evaluated. Disc displacements and osseous changes of the TMJs were assessed. Lateral and rotational disc displacements were also evaluated on coronal images. Results: No significant differences in the frequency of osseous changes of the TMJs between disc displacement with reduction and disc displacement without reduction groups were found. The erosion of the condylar head and the sclerosis of the articular eminence were more frequent in the internal derangement group than in the no disc displacement group. The flattening was the most frequently observed osseous change of both the condylar head and articular eminence. Conclusion : The relationship between internal derangement and osteoarthrosis is obscure, but it is thought that both disorders adversely affect each other.

Temporomandibular disorder(TMD) is described as a cluster of disorders characterized by pain in the preauricular area and/or the muscles of mastication; limitations or deviations in mandibular range of motion; and noises in the TMJ during mandibular function. The most common symptom in TMD patients is pain that is aggravated by chewing or other jaw function. These symptoms are appeared when the stimuli loaded in TMJ are over the physiologic tolerance. The primary goal in treatment of TMD is to alleviate pain and lor mandibular dysfunction. TMD treatment can be divided into 2 categories: reversible and irreversible methods. Reversible methods include medication, thermal therapy, habit modification, physical therapy, appliance therpy and arthrocentesis and lavage and irreversible methods include arthroscopic lysis, surgery, occlusal adjustment et al. It is widely accepted that reversible methods are ther first choice of treatments. However if reversible ones are not effective, irreversible methods are considered.

Temporomandibular joint disorder is quite common dental problem. Research has shown that 5 to 15$\%$ of the population have a TMJ disorder requiring some type of treatment. TMJ disorder's symptoms are pains in the jaw and muscles of your face, limitation of opening or closing jaw and noises in jaw joint such as clicking or popping sounds. Two patients with TMJ symptoms visited our clinic. They complained pain, limitation of jaw opening and clicking sound. We treated them by stimulating trigger points on the TMJ muscle with acupuncture and had a good effects. The symptoms is reduced or disappeared.

Osteomyelitis of the jaw is an inflammatory process of the bone marrow that is caused by odontogenic local infection and trauma such as tooth extraction and fractures in the oral and maxillofacial region. The clinical signs include pain, swelling, pus formation, and limited mouth opening. Chronic osteomyelitis presents a diagnostic challenge because of the variability of symptoms across different disease stages and varying health conditions of the patients. This report presents a case of osteomyelitis that was misdiagnosed as a temporomandibular joint disorder (TMD) after tooth extraction. The patient was treated for inflammation after tooth extraction in the early stage; however, as the osteomyelitis progressed chronically, symptoms mimicked those of a TMD. The patient was finally diagnosed with osteomyelitis 6 months after tooth extraction. A review of this case and relevant literature revealed the necessity for a differential diagnosis of chronic osteomyelitis that mimics TMD symptoms.

Objectives The aim of this review is to investigate clinical studies for manual therapy on Temporomandibular Joint Disorder and to propose for the better method of studies in the future. Methods We investigated recent clinical studies for manual therapy on Temporomandibular Joint Disorder via searching Pubmed, KISS, KISTI, KERIS, KMBASE and National Assembly Library. 21 domestic and overseas articles were analyzed and the journals, the authors, the published years, countries, methods, periods, techniques of chiropractic, outcome measures, and purpose of those articles were examined. Results Studies on manual therapy were mainly published via Cranio. The diagnostic criteria that most frequently adopted in the overseas articles were research diagnostic criteria for temporomandibular disorders, The technique of chiropractic that most frequently adopted in the articles was passive traction and translation of TMJ. Many of the studies were researched for effectiveness of the manual therapy as the secondary treatment. Conclusions Reviewing the recent clinical studies for manual therapy on temporomandibular joint disorder and figuring out the strong points and weak points of those studies are necessary to future studies. It is anticipated that this review would benefit the in-depth treatments for temporomandibular joint disorder in terms of Korean medicine.

Meniere's disease is characterized by episodic vertigo, fluctuating hearing loss, tinnitus and ear fullness. The main pathological finding is endolymphatic hydrops, but the etiology of disease and effective treatment methods are still disputed. Recently, Cervical spine disorders(CSD) and Temporomandibular disorders(TMD) have been attracting attention as one of the causes of Meniere's disease. A 65-year-old female Meniere patient with musculoskeletal problems in the cervical and mandible area was treated by Korean medical therapies including pharmacoacupuncture treatment. After 5 weeks of treatment, there was no meaningful change in hearing level evaluated with pure tone audiometry, but the subjective symptoms of Meniere improved significantly. Numerical rating scale (NRS) decreased from 10 to 0 for hearing loss, 10 to 3 for tinnitus and 8 to 3 for ear fullness. Also NRS of cervicalgia was reduced from 5 to 0 after treatment. The result suggests that the Korean medical therapy including pharmacoapuncture targeting CSD and TMD could be safe and effective method for patients with Meniere's disease.

Purpose: To evaluate displacement and morphologic changes of the temporomandibular joint (TMJ) disc in patient with internal derangement using magnetic resonance imaging (MRI). Materials and Methods: One hundred and forty five MR images of TMJs in 73 patients were evaluated. Positional and morphologic changes of the TMJ discs were assessed. Lateral or medial disc displacement was also evaluated on coronal images. Results: Among 63 discs with anterior disc displacement, 37 discs were assessed as a biconcave disc and 21 as a deformed disc. Rotational disc displacement was observed in 35 discs. Anteromedial disc displacement was observed in 29 discs, and anterolateral direction in 6 discs. Among 35 rotational displacement, 5 biconcave discs and 21 deformed discs were observed. Conclusion : Rotational and sideways displacement of TMJ discs were found to be common and an important aspect of internal derangement. This study also suggests that sagittal and coronal images of the TMJ have complementary abilities for an assessment of joint abnormality.
