For the study of the temporomandibular joint in rheumatoid arthritis 30 patients were selected who were diagnosed as rheumatoid arthritis through the clinical, radiographic examination and laboratory findings. Temporomandibular joint involvement was evaluated through the clinical, radiographic examination. The results were as follows; 1. TMJ was involved in 15 patients of 30 patients with rheumatoid arthritis. (50% involvement). 2. Duration of rheumatoid arthritis was more longer in patients with TMJ involvement than in patients without TMJ involvement. 3. Osseous changes in TMJ were in order of frequency erosion, flattening, osteophyte, sclerosis, deformity, and most common involved site was mandibular condyle. 4. Most common positional change of condyle was forward position in centric occlusion, and restricted movement of condyle in 1inch mouth opening. 5. TMJ involvement of rheumatoid arthritis was almost bilateral. 6. Main symptoms of TMJ were pain, stiffness, tenderness, limitation of mouth opening, crepitation 7. There was not the case of ankylosis. 8. There was statistically insignificant correlation between mandibular deviation and TMJ involvement, but some cases showed severe deviation on mouth opening.

목적 : 골 및 관절질환의 예민한 진단방법으로 이미 잘 알려진 골스캔의 측두하악관절장애의 진단 및 관절원판변위와 관절염의 감별진단에 있어서 임상적 유용성을 알아보고자 하였다. 방법 : 임상적으로 진단이 가능한 측두하악관절원판 변위환자 21예(일측성 13, 양측성 8), 관절염 환자 26예(일측성 23예, 양측성 3예)와 측두하악장애의 병력과 증상이 없는 대조군 39예에서 골스캔을 시행하고, 10만 계수의 두경부의 측면영상에서 측두하악관절부위?l 섭최계수를 구하여 각 측두하악관절의 섭취율과 양측측두하악관절 섭취율의 차이를 구하여, 임상증상과의 일치정도를 확인하고, 환자군에서는 경두개 및 파노라마 방사선 촬영결과와 비교 분석하였다. 결과 : 1) 측두하악관절의 단순섭취율은 정상대조군에서 $1.084{\pm}0.172$였고, 관절염으로 이환된 관절에서 $1.673{\pm}0.606$으로 가장 높았으며, 관절원판변위로 이환된 관절에서는 $1350{\pm}0.351$로 대조군에서 보다 증가되어 있었다. (p<0.01). [대조군의 평균치+2표준편차]인 1.428%이상 증가된 경우는 일측성으로 이환된 관절원판변위 환자에서 21.3%, 일측성관절염 환자에서 69.6%였다. 2) 양측 측두하악관절 단순섭취율의 차이는 대조군에서 $0.062{\pm}0.063$이었고, 일측성 관절염 환자에서 $0.608{\pm}$0.533으로 가장 높았으며, 관절원판변위 환자에서는 대조군과 차이가 없었다.(p<001). [대조군의 평균치+2표준편차]인 0.188이상 증가된 경우는 일측성 관절염환자의 87%, 일측성 관절원판변위 환자의 23%였다. 3) 방사선 촬영결과 골변화가 나타났던 관절과 골 변화가 없었던 관절사이의 섭취율 차이는 없었고, 방사선 촬영결과의 골변화와 골스캔상의 섭취율의 증가가 임상상과 일치한 경우는 일측성 관절원판변위 환자 13예 중 각각 0예와 3예, 일측성 관절염환자 23예 중 12예와 16예였다. 결론 : 측두하악관절의 장애가 유발된 경우 골스캔상 측두하악관절의 섭취가 증가되며, 이는 관절원판변위 환자보다 관절염 환자에서 더욱 현저히 관찰된다. 양측 측두하악관절 섭취율의 차이도 일측성 관절염환자에서 일측성 관절원판변위 환자보다 더욱 현저히 증가되어 보인다. 따라서 골스캔은 특히 일측성으로 이환된 측두하악관절장애의 진단 및 관절원판변위와 관절염의 구별에 도움을 줄 수 있는 유용하고 간편한 진단방법으로 생각된다.

Purpose: To evaluate osseous changes of temporomandibular joint (TMJ) in patients with rheumatoid arthritis (RA) using cone-beam computed tomography (CBCT) and to correlate the imaging findings with the severity of TMJ dysfunction, clinical findings, and laboratory findings. Materials and Methods: This study consisted of 28 subjects, including 14 RA patients and 14 controls, who were scheduled to undergo CBCT imaging for the diagnosis of a complaint not related to or affecting the TMJ. The Fonseca's questionnaire was used to assess the severity of TMJ dysfunction. Rheumatoid factor (RF) and the erythrocyte sedimentation rate (ESR) were assessed in the RA patients. CBCT was then performed in all subjects and osseous TMJ abnormalities were assessed. Results: According to the Fonseca's questionnaire, 14.3% of the patients had no TMJ dysfunction, while 50%, 21.4%, and 14.3% had mild, moderate, and severe dysfunction, respectively. RF was positive in 64.3% of patients, and the ESR level was high in 100%. Imaging findings revealed a statistically significantly higher prevalence of erosion (85.7%), flattening (89.3%), osteophyte formation (32.1%), subchondral cyst (32.1%), sclerosis (64.3%), and condylar irregularities (28.6%) in the RA patients than in the controls. No correlations were found between CBCT findings and the clinical findings, the severity of TMJ dysfunction, disease duration, or laboratory results. Conclusion: RA patients might show extensive osseous abnormalities with no/mild clinical signs or symptoms of TMJ dysfunction that necessitate TMJ imaging for these patients. CBCT is a valuable and efficient modality that can assess osseous TMJ changes in RA patients.

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.

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.

This report presents the case of a 14-year-old male with rheumatoid arthritis (RA) in both temporomandibular joints (TMJs), in whom a bone scan and laboratory tests were used to confirm the diagnosis. The patient visited the Department of Orofacial Pain and Oral Medicine at the affiliation hospital with a complaint of a 1-year history of bilateral TMJ pain and sound. Clinical examination revealed bilateral TMJ and masseter muscle pain during mouth opening and palpation. Radiological examination revealed no significant morphological changes in either TMJ. The patient was prescribed medications at the first visit to address the pain, inflammation, and stiffness. A bone scan and laboratory tests were planned/scheduled for differential diagnosis between simple arthralgia and osteoarthritis. The bone scan revealed increased radiotracer uptake in both TMJs. The laboratory tests revealed a RA factor of 82.4 IU/mL, which is more than four times the normal range. The final diagnoses were bilateral TMJ early rheumatoid arthritis (ERA) and juvenile idiopathic arthritis. We created a stabilization splint and referred the patient to the Department of Rheumatology for further evaluation of the ERA. After fitting of the stabilization splint and giving instructions regarding its use, the patient has been receiving monthly follow-up checks for symptoms and undergoes follow-up blood tests every 3 months. About 14 months after the initial visit, the pain had significantly decreased from a Visual Analog Scale score of 5 to 1, and the RA factor decreased to 66.6 IU/mL. A regular follow-up check will continue until the end of growth.

Septic arthritis of the temporomandibular joint (TMJ) is a rare disease. The most common symptoms of this disease are acute malocclusion, limited mouth opening, swelling, and tenderness of affected TMJ. These symptoms are often confused with internal derangement of the articular disc, rheumatoid arthritis, retrodiscitis, or osteoarthritis. Therefore, differential diagnosis by image examination is required. Usually, antimicrobial treatment and surgical drainage by needle aspiration, arthroscopy, or arthrotomy are effective treatment approaches. In this study, a patient who was diagnosed with septic arthritis was treated with arthrocentesis and antibiotics without significant complications. We present a case report with a review of the literature.

류마티스 관절염은 다발성 관절염을 특징으로 하는 원인 불명의 진행성 염증성 질환이다. 초기에는 관절활막이 침습되지만 점차 주위의 연골과 골이 침습되어 관절의 파괴와 변형을 초래한다. 류마티스 관절염은 손목관절, 중수지관절과 근위지절간관절이 침범하기 쉽고 그 밖의 여러 관절에서도 나타날 수 있으며 측두하악관절에서도 빈번하게 나타나는 것으로 보고되고 있다. 이 증례에서는 다른 관절에서 보다 측두하악관절에서 두드러지고 급속하게 진행되었다. 의과적 약물 치료와 더불어 16개월동안의 교합안정장치 및 물리 치료, 운동요법을 통한 치과적 처치와 측두하악관절의 경과를 보고한다. 치료중 급속한 관절의 파괴는 있었으나 더 이상의 교합변화는 없었고 하악운동과 통증은 상당히 개선되었다. 다른 관절에 비해 측두하악관절에 두드러지게 나타나게 되는 요인과 이를 가속화시키는 요인에 대해서는 앞으로의 연구가 더 필요할 것이다.

Objectives: Joint injuries frequently lead to progressive joint degeneration that causes articular disc derangement, joint inflammation, and osteoarthritis. Such arthropathies that arise after trauma are defined as post-traumatic arthritis (PTA). Although PTA is well recognized in knee and elbow joints, PTA in the temporomandibular joint (TMJ) has not been clearly defined. Interestingly, patients experiencing head and neck trauma without direct jaw fracture have displayed TMJ disease symptoms; however, definitive diagnosis and treatment options are not available. This study will analyze clinical aspects of PTA in TMJ and their treatment outcomes after joint arthrocentesis and lavage. Materials and Methods: Twenty patients with history of trauma to the head and neck especially without jaw fracture were retrospectively studied. Those patients developed TMJ disease symptoms and were diagnosed by computed tomography or magnetic resonance imaging. To decrease TMJ discomfort, arthrocentesis and lavage with or without conservative therapy were applied, and efficacy was evaluated by amount of mouth opening and pain scale. Statistical differences between pre- and post-treatment values were evaluated by Wilcoxon signed-rank test. Results: Patient age varied widely between 20 and 80 years, and causes of trauma were diverse. Duration of disease onset was measured as 508 post-trauma days, and 85% of the patients sought clinic visit within 2 years after trauma. In addition, 85% of the patients showed TMJ disc derangement without reduction, and osteoarthritis was accompanied at the traumatized side or at both sides in 40% of the patients. After arthrocentesis or lavage, maximal mouth opening was significantly increased (28-44 mm on average, P<0.001) and pain scale was dramatically decreased (7.8-3.5 of 10, P<0.001); however, concomitant conservative therapy showed no difference in treatment outcome. Conclusion: The results of this study clarify the disease identity of PTA in TMJ and suggest early diagnosis and treatment options to manage PTA in TMJ.

Mandibular trauma is developed due to traffic accident, fall down, industrial injury, and others. TMJ disorder is usually also developed after facial traumatic injury. Many authors suggested that disc displacement or tearing, acute synovitis, TMJ ankylosis, traumatic arthritis, or effusion are developed after facial trauma. It is still very controversible what is the best treatment of TMJ injury such as condylar fracture and meniscal injury. In TMJ injury, synovial inflammation is developed and pain mediators such as prostaglandin E2 or leukotriene B4 are released from the synovial membrane. This can be a cause of TMJ disorder. I present a variety of experimental study about the condylar fracture and meniscal injury and enzyme-immunoassay of synovial fluid after mandibular trauma that have been studied since 1992 and establish the treatment criteria of traumatic TMJ injury. I think that the treatment option of condylar fracture depends upon the surgeon's criteria exclusively. There are no significant differences between conservative and surgical treatment. If the aggressive functional physical therapy and long-term followup be performed, the favorable functional recovery of TMJ can be obtained. And I think that the initial surgical management of meniscus of TMJ is unnecessary in condylar fracture. And also arthrocentesis can be available to release the patient's subjective symptoms and improve the healing of injured TMJ.
