    Whilst the temporomandibular joint is in many ways unique, it is subject to all the diseases and disorders found in joints in other parts of the human skeleton. By far the most common disorder is injury, followed by arthropathy, acute and chronic dislocations, ankylosis, and in rare instances, neoplasms. The diagnosis and management of the temporomandibular joint are the primary responsibility of the oral surgeon. Nevertheless, this anatomical region is an area in which the cooperation of medical and dental disciplines may be required for the satisfactory conclusion of treatment. The more so when the disease process involves either associated psychosomatic illness or malignancy. The mainstay of the diagnosis is a careful radiological examination of the joint. There exists a delicate relationship between the dentition, the muscles of mastication, and the temporomandibular articulation, which is controlled by arthrokinetic reflex activity of the branches of the 5th cranial nerve. Imbalance between one or more of the components of this integrated system frequently leads to disturbances in function. Pain-dysfunction disorders constitute the larger part of temporomandibular joint disturbances generally encountered

    The purposes of this study were to evaluate the relationship between correlation of MR joint effusion of the temporomandibular joint and disk position, to evaluate the relationship between joint effusion and aging, and to assess the frequency of MR joint effusion of bilateral temporomandibular joints. The temporomandibular joints of 192 patients with clinical symptoms of temporomandibular joint disorders were imaged bilaterally using high field, surface-coil MR imaging. Oblique sagittal and coronal proton density-weighted and T2-weighted images were obtained. Imaging findings of joint effusion were correlated with disk position, aging, and bilateral temporomandibular joints. MR showed effusion in 4% of the joints with normal superior disk position, 36% of the joints with disk displacement with reduction, and 45% of the joints with disk displacement without reduction. There were significant differences in the incidence of joint effusion between normal disk position and anterior disk displacement with or without reduction. Younger patients less than 40 years were significant higher the incidence of joint effusion than those of older patients. A significant association was seen between joint effusion and aging. MR showed effusion in 17% of the unilateral temporomandibular joint, 24% of the bilateral temporomandibular joints. There was no significant difference between unilateral and bilateral case. These results indicated that joint effusion using MR imaging was associated with varied temporomandibular joint pathologic states. (author)

    The temporo-mandibular joint is distinguished from most other synovial joints of the body by two features: 1. the two jointed components carry teeth whose position and occlusion introduce a very strong influence on the movements of the temporo-mandibular joint and 2. its articular surfaces are not covered by hyaline cartilage, but by a dense, fibrous tissue. This paper describes the parts of the temporo-mandibular joint: the articular surfaces (the condylar process of the mandible and the glenoid part of the temporal bone), the fibrocartilaginous disc which is interposed between the mandibular and the temporal surface, the fibrous capsule of the temporo-mandibular joint and the ligaments of this joint. All these parts present a very strong adaptation at the important functions of the temporo-mandibular joint.

    Lyme borreliosis is an endemic disease in Slovenia with an incidence of around 150 patients per 100,000 inhabitants. Although the large joints are most typically affected in Lyme borreliosis, there are also periods of disease activity with arthritis or arthralgias involving smaller joints, including the temporo-mandibular joint. During the years between 2000 and 2003, two patients with Lyme borreliosis affecting the temporo-mandibular joints were treated. The patients presented with fatigue and pain in diverse muscle groups accompanied by arthralgia, which was most pronounced in the temporomandibular joint area. None of the patients were febrile or had joint effusions. Both patients were examined by means of biochemical and serological examinations for Borrelia burgdorferi using ELISA assay and Western blot test (both for IgM and IgG), plain radiographs, MR and CT scans, and scinti-scan of the temporo-mandibular joints They both had positive serum markers for an acute B. burgdorferi infection and were treated with intravenous ceftriaxone. None of the patients had clinical or laboratory signs of chronic Lyme disease activity two and four years following therapy, respectively. Roentgenographic and nuclear magnetic resonance imaging of the temporo-mandibular joints had not shown any persistent sign of acute inflammation. There are only few reports of patients with manifest temporo-mandibular joint involvement of Lyme borreliosis in the literature. This report emphasizes the importance of differential diagnosis of acute temporo-mandibular joint arthralgia, of early diagnosis of Lyme borreliosis, and of the necessity for prompt antibiotic treatment.

    The principles of interventional video tomography were applied for the real-time visualization of temporomandibular joint movements in an augmented reality environment. Anatomic structures were extracted in three dimensions from planar cephalometric radiographic images. The live-image fusion of these graphic anatomic structures with real-time position data of the mandible and the articular fossa was performed with a see-through, head-mounted display and an electromagnetic tracking system. The dynamic fusion of radiographic images of the temporomandibular joint to anatomic temporomandibular joint structures in motion created a new modality for temporomandibular joint motion analysis. The advantages of the method are its ability to accurately examine the motion of the temporomandibular joint in three dimensions without restraining the subject and its ability to simultaneously determine the relationship of the bony temporomandibular joint and supporting structures (ie, occlusion, muscle function, etc) during movement before and after treatment.

    Injuries of the temporomandibular joint are mostly due to injuries or fractures of the mandibular condyle. Fractures of the skull base involving the temporomandibular joint are rare. Classification of fractures refers to their anatomical positions and the presence or absence of a luxation. Further, it is important whether the fracture is intra- or extra-capsular. The primary imaging method should be orthopantomography. As for therapy planning, especially surgery, also evaluation of soft tissue is necessary, computed tomography is the imaging method of choice. For diagnosis of complications or internal derangement of the temporomandibular joint, magnetic resonance imaging is to be recommended. (orig.) [de

    We report an unusual and rare cause of preauricular swelling and review the most recent literature concerning synovial osteochondromatosis of the temporomandibular joint. We report the clinical and radiologic findings of a case of synovial osteochondromatosis of the temporomandibular joint that presented as preauricular swelling in a female patient. This disease typically affects large joints; fewer than 100 cases reported in the literature affect the temporomandibular joint. This case illustrates that disorders of the temporomandibular joint should also be included in the differential diagnosis of patients who present with a preauricular mass.

    Tinnitus has been described in temporomandibular joint dysfunction for a long time. Yet, other disorders, such as hearing loss, stress, anxiety and depression, play a major role in the pathophysiology of tinnitus. Temporomandibular joint dysfunctions seem to increase the risk of tinnitus in patients with other predisposing factors. Especially somatosensory tinnitus, which is characterized by sound modulations with neck or mandible movements, is frequently associated with temporomandibular joint dysfunction, but it is not pathognomonic of such a disorder. In such cases, functional therapy of the temporomandibular joint should be part of the multidisciplinary rehabilitation of patients with tinnitus. Copyright © 2016 Elsevier Masson SAS.

    This paper determines the frequency of MR signs of abnormal temporomandibular joints (TMJs) in asymptomatic volunteers. Forty-two volunteers with 84 clinically normal TMJs were imaged in the sagittal and coronal planes with surface coil MR imaging. Sagittal closed and open and coronal closed views were obtained bilaterally in all volunteers. The images were classified as normal (superior disk position) or abnormal (disk displacement of degenerative joint disease). Eighteen joints in 11 volunteers were abnormal; 12 had disk displacement with reduction and six had disk displacement without reduction, with associated degenerative joint disease in three of the six. Asymptomatic internal derangement and degenerative joint disease occur in about one-fourth of asymptomatic volunteers

    To determine whether there is a relationship between abnormal temporomandibular joint radiographic findings and age or gender in a sample of preorthodontic patients. Individualized corrected sagittal tomographs of 188 temporomandibular joints in 94 preorthodontic patients, aged 11 to 29 years, were taken and viewed by an observer blinded to clinical records. The study population was divided into 2 aged groups (11-15 years and 16-29 years) for comparative purpose. Temporomandibular joint radiographic findings were classified as normal or abnormal. There was no difference in ratio of abnormal to normal findings between the both aged groups. The frequency of osseous abnormalities was similar with that of abnormalities of condylar position. Abnormalities in CP and JS were most frequent in all aged groups. There is no significant difference between ages or genders for temporomandibular joint radiographic abnormalities.

    The presence and content of calcitonin gene-related peptide (CGRP) is evaluated in the hyperplastic retrodiscal tissue of the temporomandibular joint in patients with joint degenerative disease by radioimmunoassay. Study population has included 8 female patients in pre-menopausic status, without to be pregnant, without to be lactating for a year and with diagnostic of joint degenerative disease (osteoarthrosis). Pain levels are registered with visual analog scale, where 0 is absence of pain and 16 acute pain. A bone degeneration is classified as mild, moderate and severe, according to findings of nuclear magnetic resonance. The 15 retrodiscal hyperplastic tissue samples are taken from patients undergoing to open surgery of temporomandibular joint. The specimens were placed in plastic blocks with freezing medium and are stored at -70 degrees celsius until neuropeptide extraction by radioimmunoassay with kit for CGRP. A directly proportional relationship is established between the degree of bone degeneration and neuropeptide expression and between the osteoarthrosis classification with analogue visual scale. Findings have shown definitive correlation between pain levels and expression of neuropeptide. CGRP is expressed in the retrodiscal tissue of temporomandibular joint in human with joint degenerative disease and is directly related with levels osteoarthrosis and pain [es

    Temporomandibular joint (TMJ) forms an integral functional part of stomatognathic system. Position, shape, structure and function of teeth have an influence on the proper functioning and health of TMJ. But a problem associated with TMJ is often neglected, and treatment for it is mostly restricted to palliative therapy. A proper understanding of the underlying cause of temporomandibular joint disorder (TMD) is necessary to device a proper treatment plan. Etiology of TMDs varies from idiopathic...

    To construct self-assembly fibrocartilage model of goat temporomandibular joint disc and observe the biological characteristics of the self-assembled fibrocartilage constructs, further to provide a basis for tissue engineering of the temporomandibular joint disc and other fibrocartilage. Cells from temporomandibular joint discs of goats were harvested and cultured. 5.5 x 10(6) cells were seeded in each agarose well with diameter 5 mm x depth 10 mm, daily replace of medium, cultured for 2 weeks. One day after seeding, goat temporomandibular joint disc cells in agarose wells were gathered and began to self-assemble into a disc-shaped base, then gradually turned into a round shape. When cultured for 2 weeks, hematoxylin-eosin staining was conducted and observed that cells were round and wrapped around by the matrix. Positive Safranin-O/fast green staining for glycosaminoglycans was observed throughout the entire constructs, and picro-sirius red staining was examined and distribution of numerous type I collagen was found. Immunohistochemistry staining demonstrated brown yellow particles in cytoplasm and around extracellular matrix, which showed self-assembly construct can produce type I collagen as native temporomandibular joint disc tissue. Production of extracellular matrix in self-assembly construct as native temporomandibular joint disc tissue indicates that the use of agarose wells to construct engineered temporomandibular joint disc will be possible and practicable.

    Necrotising otitis externa is associated with high morbidity and mortality rates. This study investigated whether temporomandibular joint involvement had any prognostic effect on the course of necrotising otitis externa in patients who had undergone hyperbaric oxygen therapy after failed medical and sometimes surgical therapy. A retrospective case series was conducted of patients in whom antibiotic treatment and surgery had failed, who had been hospitalised for further treatment and hyperbaric oxygen therapy. Twenty-three patients with necrotising otitis externa were identified. The temporomandibular joint was involved in four patients (17 per cent); these patients showed a constant gradual improvement in C-reactive protein and were eventually discharged free of disease, except one patient who was lost to follow up. Four patients (16 per cent) without temporomandibular joint involvement died within 90 days of discharge, while all patients with temporomandibular joint involvement were alive. Three patients (13 per cent) without temporomandibular joint involvement needed recurrent hospitalisation including further hyperbaric oxygen therapy; no patients with temporomandibular joint involvement required such treatment. Patients with temporomandibular joint involvement had lower rates of recurrent disease and no mortality. Therefore, we suggest considering temporomandibular joint involvement as a positive prognostic factor in necrotising otitis externa management.

    Changing lifestyles, decreasing physical activity, which is increasing the number of degenerative joint diseases of various etiology, and certain dental procedures are increasing the number of patients complaining of pain in their temporomandibular joints. The aim of the study was to assess the benefits of comprehensive physiotherapy sessions in order to decrease the number of temporomandibular joint problems, thereby improving the patient's quality of life. An examination by a dentist determined each patient's treatment plan, which consisted of a medical exam, physical therapy and education. Each form of treatment was applied 10 times at intervals of 7-14 days. The main goal of the therapeutic physical education was to redress the muscle imbalance in the mandibular joint. This was achieved by restoring balance between the masticatory muscles, along with releasing the spastic shrouds found in the masticatory muscles. The aim of education was to teach the patient exercises focused on the temporomandibular joint and masticatory muscles. The intensity of the exercises and their composition were individually adjusted and adapted to their current state. Physical therapy consisted of the application of pulsed magnetic therapy, laser therapy, and non-invasive positive thermotherapy. The above procedure was conducted on a therapeutic group of 24 patients (3 men and 20 women). In the course of therapy, there were no complications, and all patients adhered to the prescribed regime. None reported any side effects. The mean treatment duration was 123 +/- 66 days. The outcome of the therapy was evaluated as described in the methodology, the degree of pain affecting the joint, and the opening ability of the mouth. In both parameters, there was a significant decline in patient pain. In a study devoted to tactics of rehabilitation treatment for temporomandibular joint disorders, the need for comprehensive long-term therapy, involving education, and learning proper chewing habits

    Bilateral assessment of the temporomandibular joint space in children without joint disease is reported. Twenty-eight children were examined with conventional radiography and 23 with tomography. High prevalence of asymmetric joint spaces with both techniques indicated that great care should be taken when using narrowing or widening of the joint space as a diagnostic criterion in children with juvenile rheumatoid arthritis. Other signs, such as restricted translation of the mandibular head, and clinical symptoms should be evaluated. (Auth.)

Un avance importante en cirugía reconstructiva es el alargamiento de la mandibula por distracción que tiene la ventaja de una cirugía menos agresiva que determinados tipos de osteotomías. Con esta técnica una osteotomía bicortical se hace en distintas zonas de la mandibula colocandose el distractor hasta alcanzar los efectos deseados. Aunque las fuerzas aplicadas se han mostrado eficaces para alargar la mandíbula, sus efectos en segmentos proximales y distales, incluyendo la articulación temporomandibular no han sido analizados sistemáticamente. En este artículo se repasa trabajos experimentales y clínicos en los que se detalla la relación entre distracción mandibular y articulación temporomandibular.Abstract: Patients with severe craniofacial abnormalities often require multiple and complex surgical procedures to reconstruct maldeveloped hard and soft tissues of the maxillofacial complex. An important advance in reconstructive surgery is mandibular lengthening by gradual distraction, which takes advantage to be less agressive surgery than some osteotomies. With this technique, a bicortical osteotomy is made at the angle of the deficient mandible, and an expansion appliance is placed across the osteotomy line. Although the applied forces have been shown to lengthen the mandible effectively in the region of the application, their effects on the proximal and distal mandibular segments, including the temporomandibular joint region, have not been analyzed systematically. In this article, we study several experimental and clinical papers where it describes the relationship between mandibular distraction and temporomandibular joint.

    The diagnostic value of conventional oblique-lateral transcranial standard projections for radiography of the temporomandibular joints is limited by various anatomical factors and the projection geometry. Improved results are obtained by individualization of the projection. The author describes a method for determining the individually optimum oblique-lateral projection, a method which is based on pre-exposure fluoroscopy of the temporomandibular joint with an electronic image intensifier system incorporating a television chain. The method has been employed as routine practice for 15 years; it has been modified several times and enables documentation studies to be made with an unusually high degree of reproducibility with respect to beam projection.

    Rear-end impacts account for more than one-third of vehicle accidents, and nearly 40% of these accidents produce whiplash injuries. Whiplash injury to the neck has often been considered a significant risk factor for the development of temporomandibular disorders (TMD). The objective of this study was to simulate the dynamic response of the temporomandibular joint during two types of impacts: a rear end and a frontal impact. To understand the dynamic forces acting on the joint, we extended a previous human temporomandibular joint model and analyzed the stress distributions in the soft elements of the joint. In the rear-end impact, it could be appreciated that the inertia of the mandible caused it to move posteriorly slower than the head, and this resulted in downward and forward displacements of the disc-condyle complex relative to the cranial base. Consequently, a rapid and big mouth opening occurs. In contrast, during the frontal impact, the mouth hardly opened, because the superior maxilla pushed the mandible to move together. There was not differential movement between bony components of the joint and therefore the soft tissues of the joint were not subjected to high loads. From these results, and despite the limitations of the simulations performed, we could conclude that neither a rear-end impact at low-velocity nor a frontal impact would produce damage to the soft tissues of the joint.

    Temporomandibular joint (TMJ) is one of the most complex joints of the human body. Due to its unique movement, in terms of combination of rotation and translator movement, disc of the joint plays an important role to maintain its normal function. In order to sustain the normal function of the TMJ, disc must be kept in proper position as well as maintain normal shape in all circumstances. Once the disc is not any more in its normal position during function of the joint, disturbance of the joint can be occurred which will lead to subsequent distortion of the disc. Shape of the disc can be influenced by many factors i.e.: abnormal function or composition of the disc itself. Etiology of the internal derangement of the disc remains controversial. Multifactorial theory has been postulated in most of previous manuscripts. Disc is composed of mainly extracellular matrix. Abnormal proportion of collagen type I & III may also leads to joint hypermobility which may be also a predisposing factor of this disorder. Thus it can be recognized as local manifestation of a systemic disorder. Different treatment modalities with from conservative treatment to surgical intervention distinct success rate have been reported. Recently treatment with extracellular matrix injection becomes more and more popular to strengthen the joint itself. Since multifactorial in character, the best solution of the treatment modalities should be aimed to resolve possible etiology from different aspects. Team work may be indication to reach satisfied results. Copyright © 2018. Published by Elsevier Taiwan.

    A 64-year-old woman with diabetes mellitus was admitted to our hospital with left hemiparesis of sudden onset. A brain MRI demonstrated a cerebral infarction in the ventral part of the right lower pons. When left hemiparesis worsened, she had dislocation of the temporo-mandibular joints repeatedly. Then, her lower jaw deviated to the right when she opened her mouth. Also, there was decreased contraction of the right masseter when she clenched her teeth. These findings suggest that there was trigeminal motor paralysis on the right side resulting from involvement of the intrapontine trigeminal motor nerve. She has no history of dislocation of the temporo-mandibular joints. An X-ray film showed that the temporo-mandibular joints were intact. Thus, it is possible that deviation of the lower jaw was the cause of this dislocation. We suspect that dislocation of the temporo-mandibular joints may occur as a complication of unilateral trigeminal motor paralysis. This has not been reported to our knowledge.

    Stock prosthetic temporomandibular joint replacements come in limited sizes, and do not always encompass the joint anatomy that presents clinically. The aims of this study were twofold. Firstly, to design a personalized prosthetic total joint replacement for the treatment of a patient's end-stage temporomandibular joint osteoarthritis, to implant the prosthesis into the patient, and assess clinical outcome 12-months post-operatively; and secondly, to evaluate the influence of changes in prosthetic condyle geometry on implant load response during mastication. A 48-year-old female patient with Grade-5 osteoarthritis to the left temporomandibular joint was recruited, and a prosthesis developed to match the native temporomandibular joint anatomy. The prosthesis was 3D printed, sterilized and implanted into the patient, and pain and function measured 12-months post-operatively. The prosthesis load response during a chewing-bite and maximum-force bite was evaluated using a personalized multi-body musculoskeletal model. Simulations were performed after perturbing condyle thickness, neck length and head sphericity. Increases in prosthetic condyle neck length malaligned the mandible and perturbed temporomandibular joint force. Changes in condylar component thickness greatly influenced fixation screw stress response, while a more eccentric condylar head increased prosthetic joint-contact loading. Post-operatively, the prosthetic temporomandibular joint surgery reduced patient pain from 7/10 to 1/10 on a visual analog scale, and increased intercisal opening distance from 22 mm to 38 mm. This study demonstrates effectiveness of a personalized prosthesis that may ultimately be adapted to treat a wide-range of end-stage temporomandibular joint conditions, and highlights sensitivity of prosthesis load response to changes in condylar geometry.

    Imaging of the temporomandibular joint(TMJ) is continuously evolving with advancement of imaging technologies. Many different imaging modalities are currently used to evaluate the TMJ. Magnetic resonance imaging is commonly used for evaluation of the TMJ due to its superior contrast resolution and its ability to acquire dynamic imaging for demonstration of the functionality of the joint. Computed tomography and ultrasound imaging have specific indication in imaging of the TMJ. This article focuses on state of the art imaging of the temporomandibular joint. Relevant normal anatomy and biomechanics of movement of the TMJ are discussed for better understanding of many TMJ pathologies. Imaging of internal derangements is discussed in detail. Different arthropathies and commontumors are also discussed in this article.

    Disc and condylar position were observed on MRIs of temporomandibular joint disorder patients and condylar position agreement between MRI and tranascranal radiography was evaluated. MRI and transcranial radiographs of both TM joints from 67 patients with temporomandibular disorder were used. On MRI, the position and shape of disc and condylar position as anterior, middle, posterior was evaluated at medial, center, and lateral views. On transcranial radiographs, condylar position was evaluated using the shortest distance from condyle to fossa in anterior, superior, and posterior directions. 1. On MRI, 96 joints (71.6%) of 134 had anterior disc dispalcement with reduction and 38 joints (28.4%) without reduction. 2. Fourteen (14.6%) of 96 reducible joints showed anterior condylar position. 19 (19.8%) showed central position, 63 joints (65.6%) showed posterior position. Two joints (5.3%) of 38 non-reducible joints showed anterior condylar position, while 9 (23.7%) showed central position, and 27 (71.1%)-posterior position. 3. In 85 joints (63.4%) of 134, the transcranial condylar position agreed with that of the central MRI view, 10 joints (7.5%) with that of medial, 16 joints (11.6%) with that of lateral, and 23 joints (17.2%) disagreed with that of MRI. On MRI, most of the reducible and non-reducible joints showed posterior condylar position. Transcranial radiographs taken with machine designed for TMJ had better agreement of condylar position with that of MRI. Extremely narrow joint spaces or very posterior condylar positions observed on transcranial radiographs had a little more than fifty percent agreement with those of MRIs.

    Headache is a common symptom, that can be extremely disabling, affecting 26 million of patients only in Italy. ICHD-II has reported two categories: "primary headaches" and "secondary headaches". Temporomandibular joint disorders can lead to a secondary headaches. We want to evaluate the prevalence and clinical features of headache among a series of patients having temporomandibular joint disorders and we illustrate the evolution of headache following medical treatament of temporomandibular joint (TMJ) disorders. This is a retrospective study carried out on chart review of 426 consecutive patients with various degrees of temporomandibular disorders and treated with medical devices from 2007 to 2011. Headache was reported by 73 patients (17.14%). Headache was observed in 36 of 51 patients with lock and in 32 out of 130 patients with mandibular deflections (Table I). The remaining 5 patients with headache had articular noise. Headache is not a rare finding in a population with temporomandibular dysfunctions and is more often a tension-type rather than trigeminal headache.

    The presence and content of calcitonin gene-related peptide (CGRP) is evaluated in the hyperplastic retrodiscal tissue of the temporomandibular joint in patients with joint degenerative disease by radioimmunoassay. Study population has included 8 female patients in pre-menopausic status, without to be pregnant, without to be lactating for a year and with diagnostic of joint degenerative disease (osteoarthrosis). Pain levels are registered with visual analog scale, where 0 is absence of pain and 16 acute pain. A bone degeneration is classified as mild, moderate and severe, according to findings of nuclear magnetic resonance. The 15 retrodiscal hyperplastic tissue samples are taken from patients undergoing to open surgery of temporomandibular joint. The specimens were placed in plastic blocks with freezing medium and are stored at -70 degrees celsius until neuropeptide extraction by radioimmunoassay with kit for CGRP. A directly proportional relationship is established between the degree of bone degeneration and neuropeptide expression and between the osteoarthrosis classification with analogue visual scale. Findings have shown definitive correlation between pain levels and expression of neuropeptide. CGRP is expressed in the retrodiscal tissue of temporomandibular joint in human with joint degenerative disease and is directly related with levels osteoarthrosis and pain [Spanish] La presencia y el contenido del peptido relacionado con el gen de la calcitonina (CGRP) es evaluado en el tejido retrodiscal hiperplasico de la articulacion temporomandibular en pacientes con enfermedad degenerativa articular mediante radioinmunoensayo.

    The aim of this study was to analyze three-dimensional images of the arterial supply to the temporomandibular joint. Ten patients (five men and five women, mean age 36 years) without signs or symptoms of temporomandibular disorders, who underwent contrast-enhanced computed tomographic (CT) scanning with intravenous contrast, were studied. The direct volume rendering technique of CT images was used, and a data set of images to visualize the vasculature of the human temporomandibular joint in three dimensions was created. After elaboration of the data through post-processing, the arterial supply of the temporomandibular joint was studied. The analysis revealed the superficial temporal artery, the anterior tympanic artery, the deep temporal artery, the auricular posterior artery, the transverse facial artery, the middle meningeal artery, and the maxillary artery with their branches as the main arterial sources for the lateral and medial temporomandibular joint. The direct volume rendering technique was found to be successful in the assessment of the arterial supply to the temporomandibular joint. The superficial temporal artery and maxillary artery ran along the lateral and medial sides of the condylar neck, suggesting that these arteries are at increased risk during soft-tissue procedures such as an elective arthroplasty of the temporomandibular joint.

    Full Text Available Temporomandibular joint (TMJ forms an integral functional part of stomatognathic system. Position, shape, structure and function of teeth have an influence on the proper functioning and health of TMJ. But a problem associated with TMJ is often neglected, and treatment for it is mostly restricted to palliative therapy. A proper understanding of the underlying cause of temporomandibular joint disorder (TMD is necessary to device a proper treatment plan. Etiology of TMDs varies from idiopathic reasons to systemic disorders. The option of Gnathological splint is a conservative, safe and an effective mode of therapy for TMDs caused by occlusal discrepancies (fulcrum/interferences.

    Full Text Available Congenital temporomandibular joint (TMJ ankylosis is an uncommon condition that presents itself at or soon after birth in the absence of acquired factors that could have contributed to the ankylosis such as infection and trauma. The experience of managing one such case is reported in light of a review of the literature on this condition. Key management principles include adequate removal of the ankylotic mass, costochondral grafting, and post-op physiotherapy. Most patients reported in the literature with the condition experienced relapse. This echoes our own experience where there was recurrence of the ankylosis. However, after removal of the ankylotic mass, the patient maintains a satisfactory maximal incisal opening (MIO till the present day. The additional challenges faced in the congenital form in addition to the already complex management of acquired paediatric temporomandibular joint ankylosis are (1 much earlier insult to the TMJ, (2 reduced opportunity for neuromuscular development of the muscles of mastication, and (3 reduced compliance with postoperative physiotherapy programmes due to the younger age of these patients.

    The radiation exposure caused by standardized examinations of the temporomandibular joint has been determined with the aid of 660 exposures of an Alderson phantom. Comparative examinations were performed with the classic contact technique according to Parma to elucidate the results obtained. The lowest surface exposure was observed in contact examinations of the temporomandibular joint. Application of a flat cone led to a 13-fold reduction in surface exposure compared to contact examinations according to Parma. Furthermore, radiation exposure strongly decreased from the irradiation field to the adjacent area if a cone (flat cone and ear cone) was used. (author)

    Disc displacement of the temporomandibular joint has been defined as an abnormal relationship between the articular disc and the mandibular condyle, fossa and articular eminence. Disc displacements may occur without immediate interference in the function of the joint. Magnetic resonance imaging shows high diagnostic accuracy in the determination of articular disc position and has been indicated as the diagnostic method of choice for soft tissue abnormalities of the temporomandibular joint. The aim of this study is to review the literature including the normal features and different types of disc displacement of the temporomandibular joint as well as the imaging findings, emphasizing the role of magnetic resonance imaging.

    Full Text Available The study describes a rare clinical case of synovial chondromatosis of the temporo-mandibular joint, in a 53 year-old patient. In the prehospital stage, the patient was examined by additional diagnostic methods – 3D CT and subsequent computer simulation, in view of subsequent surgery. In January 2015, partial synovektomy of the right temporo-mandibular joint with removal of cartilaginous impurities was performed under general anesthesia. After histopathological confirmation of the clinical diagnosis, the patient was discharged in satisfactory condition, with recommendations for further examination and radiological control. Synovial chondromatosis of the temporo-mandibular joint is a disease characterized by impaired formation of cartilage or of intraarticular, cartilaginous, and relatively rare bone impurities. An important role in the diagnosis of joints’ synovial chondromatosis is played by the instrumental research methods, especially X-ray. Surgical treatment is recommended as a function of the prevalence of lesions.

    Total prosthetic replacement of the temporo-mandibular joint (TMJ) has become a common procedure, but it is usually limited to the TMJ itself. We report about one case of complex prosthetic joint reconstruction extending to the neighbouring bony structures. A 57-year-old patient, operated several times for a cranio-facial fibrous dysplasia, presented with a recurring TMJ ankylosis and a complexe latero-facial bone loss on the right side. We performed a reconstruction procedure including the TMJ, the zygomatic arch and the malar bone by mean of custom made composite prosthesis (chrome-cobalt-molybdenum-titanium and polyethylene). Five years postoperatively, mouth opening, nutrition, pain and oral hygiene were significantly improved. Nowadays technical possibilities allow for complex facial alloplastic reconstructions with good medium term results. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    2018-01-01

    Full Text Available Summary:. Infection of the temporomandibular joint (TMJ is a rare pediatric condition resulting from the introduction of pathogens into the joint by hematogenous seeding, local extension, or trauma. Early recognition of the typical signs and symptoms including fever, trismus, preauricular swelling, and TMJ region tenderness are critical in order to initiate further evaluation and prevent feared complications of fibrosis, ankylosis, abnormal facial structure, or persistence of symptoms. Contrast-enhanced computed tomography with ancillary laboratory analysis including erythrocyte sedimentation rate, C-reactive protein, and white blood cell count are beneficial in confirming the suspected diagnosis and monitoring response to therapy. Initial intervention should include empiric parenteral antibiotics, early mandibular mobilization, and joint decompression to provide synovial fluid for analysis including cultures. This report describes a case of TMJ bacterial arthritis in a healthy 6-year-old male who was promptly treated nonsurgically with intravenous antibiotics and localized needle joint decompression with return to normal function after completion of oral antibiotics and physical therapy.

    Full Text Available Rheumatoid arthritis (RA is a chronic, systemic, autoimmune inflammatory disorder that is characterized by joint inflammation, erosive properties and symmetric multiple joint involvement. Temporomandibular joint (TMJ is very rare to be affected in the early phase of the disease, thus posing diagnostic challenges for the dentist. Conventional radiographs fail to show the early lesions due to its limitations. More recently cone-beam computed tomography (CBCT has been found to diagnose the early degenerative changes of TMJ and hence aid in the diagnosis of the lesions more accurately. Our case highlights the involvement of TMJ in RA and the role of advanced imaging (CBCT in diagnosing the bony changes in the early phase of the disease.

    Thirty patients with temporo-mandibular joint dysfunction were selected to investigate the changes in otoacoustic emissions before and after conservative treatment of their temporo-mandibular joints. Pure tone audiometry, transient-evoked otoacoustic emissions (TEOAE), distortion-product otoacoustic emissions (DPOAE) as well as a tinnitus questionnaire were administered to all patients before and after therapy. Therapy was conservative in the form of counselling, physiotherapy, anti-inflammatory agents, muscle relaxants, and occlusal splints. Results indicated insignificant changes in the TEOAEs, whereas there were significant increases in distortion product levels at most of the frequency bands. These results were paralleled to subjective improvement of tinnitus.

    Objective A survey was held to establish whether laypeople knew the location of their temporomandibular joint. Methods A sample of 61 participants, visiting their dental office for a routine check-up, was given a three-question survey of whether they knew the location of their temporomandibular joint and could point to this location. Results Thirty-eight participants answered the question affirmatively. Only 13 pointed to the correct location. Of these, six participants received consultation for TMD in the past, three participants were healthcare providers, and four participants actually had knowledge of the exact location. Out of 23 participants who did not know the location, one accidently designated the correct position. Conclusion The location of the temporomandibular joint is not a well-known site for many patients. In the presence of orofacial pain, it seems advisable to let the patient designate and record the site of the pain on a drawing on the patient chart.

    Aim and objectives. The morphology and position of the temporo-mandibular disc are key issues in the diagnosis and treatment of arthrogenous temporo-mandibular disorders. Magnetic resonance imaging and arthroscopy are used today to identify: flattening of the pars posterior of the disc, perforation and/or adhesions in the pars intermedia of the disc and disc displacements. The present study proposes the investigation of the temporo-mandibular joint disc by optical coherence tomography (OCT). Material and methods. 8 human temporo-mandibular joint discs were harvested from dead subjects, under 40 year of age, and conserved in formalin. They had a normal morphology, with a thicker pars posterior (2,6 mm on the average) and a thinner pars intermedia (1mm on the average). We investigated the disc samples using two different OCT systems: an en-face OCT (time domain (TD)-OCT) system, working at 1300 nm (C-scan and B-scan mode) and a spectral OCT system (a Fourier domain (FD)-OCT) system , working at 840 nm (B-scan mode). Results. The OCT investigation of the temporo-mandibular joint discs revealed a homogeneous microstructure. The longer wavelength of the TD-OCT offers a higher penetration depth (2,5 mm in air), which is important for the analysis of the pars posterior, while the FD-OCT is much faster. Conclusions: OCT is a promising imaging method for the microstructural characterization of the temporo-mandibular disc.

    The most frequent symptom of craniomandibular dysfunction is pain in the preauricular area or in the temporo-mandibular joint, usually localized at the level of the masticatory musculature. Patients sometimes also complain of reflect otalgia, headaches and facial pain. Osteoarthrosis is a frequent degenerative debilitating chronic disorder that can affect the temporomandibular joint. It causes pain and articular rigidity, a reduction in mobility, and radiological alterations are visible in stratigraphy. The aim of this study was to compare the efficacy of a topically applied non-steroid anti-inflammatory drug that has recently become commercially available (diclofenac sodium in a patented carrier containing dimethyl sulfoxide, that favours transcutaneous absorption) which is commonly used to alleviate pain in knee or elbow joints, versus oral diclofenac, in the treatment of symptoms of temporomandibular joint dysfunction. Dysfunction of the temporomandibular joint was diagnosed in 36 adult patients. The patients were randomized in two age- and gender -matched groups. Group A (18 patients) received oral diclofenac sodium administered after a meal in 50-mg tablets twice a day for 14 days. Group B (18 patients) received 16 mg/ml topical diclofenac (diclofenac topical solution, 10 drops 4 times a day for 14 days). All patients completed a questionnaire at the start and end of therapy. Patients were asked to quantify on a graded visual analogue scale and to reply to questions about the pain and tenderness of the temporomandibular joint and the functional limitation of mouth opening. Patients were also requested to report side-effects of the treatment. All patients showed relief from pain after treatment: the difference between the two groups was not significant (p > 0.05). Post-treatment, 16 patients of group A had epigastralgic symptoms. Three patients treated with topical diclofenac showed a modest irritation of the temporomandibular joint region, and disappeared

    Full Text Available The most common cause of orofacial pain is the Temporomandibular Joint Disorder (TMD, a collective term used to describe a group of medical disorders causing temporomandibular joint (TMJ pain and dysfunction. As the causes of TMD are varied and run the gamut from mechanical issues, such as disc degeneration and dislocation or erosion of the fibrocartilaginous surfaces of the condyle, fossa, and articular eminence, the treatment approaches for the chronic TMJ case are also quite varied. As surgery is considered a last resort for TMD, it is common for sufferers to seek out alternatives and one of the alternative treatments is ′Prolotherapy,′ which is also known as Regenerative Injection Therapy. This article provides an overview of this new alternative therapy.

    Recurrent pains of the temporomandibular joint represent a frequent symptom with numerous different causes. CT and MRI can reliably show the cause of these disorders and therefore have substituted conventional X-ray imaging. Modern multi-slice-CT (MSCT) allows for examination of the skull base including the mandible in a very short time with thinnest slice collimation (0.75 mm). With 2D- and 3D- reformations reconstructed out of this volume data set in parasagittal, coronal or any other arbitrary slice orientation excellent imaging of fractures and bony changes of arthrosis as well as benign and malignant tumors of the temporomandibular joint can be performed. MRI offers very good soft tissue contrast in order to visualize the intra-articular disc, the ligaments and muscles, as well the possibility to acquire cross sectional images in any user-defined orientation. MRI is the method of choice to diagnose 'internal derangement', particularly displacement of the intra-articular disc and inflammatory disease of the temporomandibular joint. The present paper will provide diagnostic strategies for the use of MSCT or MRI imaging concerning the different causes of disorders to the temporomandibular joint. (orig.)

    Attributing dysfunction of the temporomandibular joint (TMJ) to whiplash injury is a difficult problem to solve. TMJ disorders do not seem to be secondary to direct articular trauma but rather caused by a postural disorder of the cervical spine. Occlusal disorders and stress further complicate the picture. Four clinical cases illustrate a new hypothetical approach.

    The temporomandibular joint and its associated musculature are described in a neonate gray whale (Eschrichtius robustus) and serve as the basis for direct anatomical comparisons with the temporomandibular region in other clades of baleen whales (Mysticeti). Members of the right whale/bowhead whale clade (Balaenidae) are known to possess a synovial lower jaw joint, while members of the rorqual clade (Balaenopteridae) have a nonsynovial temporomandibular joint characterized by a highly flexible fibrocartilaginous pad and no joint capsule. In contrast, the gray whale possesses a modified temporomandibular joint (intermediate condition), with a vestigial joint cavity lacking a fibrous capsule, synovial membrane, and articular disk. In addition, the presence of a rudimentary fibrocartilaginous pad appears to be homologous to that seen in balaenopterid mysticetes. The intrinsic temporomandibular musculature in the gray whale was found to include a multibellied superficial masseter and a single-bellied deep masseter. The digastric and internal pterygoid muscles in E. robustus are enlarged relative to the condition documented in species of Balaenoptera. A relatively complex insertion of the temporalis muscle on the dentary is documented in the gray whale and the low, knob-like process on the gray whale dentary is determined to be homologous with the prominent coronoid process of rorquals. Comparison with the anatomy of the temporomandibular musculature in rorquals reveals an increased importance of alpha rotation of the dentary in the gray whale. This difference in muscular morphology and lines of muscle action is interpreted as representing adaptations for suction feeding. © 2015 Wiley Periodicals, Inc.

    Full Text Available Temporomandibular joint dysfunction is a functional disorder concerned with the abnormal functioning of the muscles of the stomatognathic system and temporomandibular joints involved in the dynamic movements of the jaw and surrounding structures. The aim of the study was to compare the level of C-reactive protein in patients with pain and painless forms of temporomandibular joint dysfunction. Materials and methods. The study group consisted of 72 patients who reported to the prosthetic treatment because of temporomandibular joint dysfunction. The study group included 36 patients with pain form of dysfunction, and the control group included 36 patients with painless form of disorder. Each patient underwent specialized examination of functional disorders in order to diagnose the type of dysfunction and was commissioned to carry out a study of the blood test concerned with evaluation of the C-reactive protein (CRP level in the same analytical laboratory. The results of the investigation were subjected to statistical analysis. The research obtained approval from the Ethics Committee of the Jagiellonian University (KBET/125/L/2013. Level of Evidence for primary research was established as type V. Results. The mean values of C-reactive protein levels in both groups were in the normal range and did not differ statistically significantly, which indicates the fact that the pain form of the temporomandibular joint disorders is not associated with inflammation of the soft tissues of the joint. Conclusion. Painful form of the temporomandibular joint dysfunctions is not connected with the inflammation of joints.

    Contrary to the accepted opinion, transverse movement is possible in the temporo-mandibular joint of the dog. This movement is arched and is important for mastication. Analysis of transverse movement of the temporo-mandibular joint was done in 20 dog breeds. Accidentally dysplasia of the temporo-mandibular joint was found in the dachshund, a phenomenon which has not been described before.

    Full Text Available ABSTRACT Temporomandibular joint dysfunction is a set of disorders involving the masticatory muscles, temporomandibular joint and associated structures. It is known that the progression of motor symptoms in Parkinson's disease is an indication that these people are more prone to the development of this dysfunction. Thus, this study aims to investigate the signs and symptoms of temporomandibular dysfunction in people with Parkinson's disease. The search was performed in the databases: MEDLINE/ PubMed, LILACs, CINAHL, SCOPUS, Web of Science and PEDro, without timing or language restriction. Specific descriptors were used for each database and keywords, evaluated by the instruments: Critical Appraisal Skill Program and Agency for Health care and Research and Quality. A total of 4,209 articles were found but only 5 were included. After critical analysis of the methodology of the articles, one did not reach the minimum score required by the evaluation instruments, thus, it was excluded. The selected articles addressed, as signs and symptoms of temporomandibular joint dysfunction, the following: myofascial pain, bruxism, limitation of mouth opening, dislocation of the articular disc and asymmetry in the distribution of occlusal contacts. Further studies are needed in order to determine the relationship between cause and effect of the analyzed variables, so as to contribute to more specific and effective therapeutic interventions.

    To assess the feasibility and clinical outcomes of artificial condylar process in reconstruction of the temporomandibular joint. Between January 2005 and January 2010, the reconstructions of the temporomandibular joints with artificial condylar process were performed in 10 cases (11 sides, including 7 left sides and 4 right sides). There were 7 males and 3 females with an average age of 50 years (range, 40-68 years). Mandibular condyle defects were caused by mandible tumor in 7 patients with a mean disease duration of 15 months (range, 9-24 months) and by bilateral condylar fractures in 3 patients with the disease duration of 2, 3, and 2 days respectively. According to Neff classification, there were type M and A in 1 case, type M and B in 1 case, and type M in one side and subcondylar fracture in the other side in 1 case. Incisions in all patients healed by first intention, and no complication occurred. All cases were followed up 1 to 4 years, showed facial symmetry and good occluding relation, and the mouth opening was 22-38 mm (mean, 30 mm). No temporomandibular joint clicking or pain and no recurrence of tumor were observed. Most of the artificial condylar process were in good position except 1 deviated from the correct angle slightly. All the patients could have diet normally. The results of temporomandibular joint reconstruction after tumor resection with artificial condylar process are good, but the clinical outcome for intracapsular condylar fracture is expected to be further verified.

    Temporomandibular disorders (TMD) are a subgroup of craniofacial pain problems involving the temporomandibular joint (TMJ), masticatory muscles, and associated head and neck musculoskeletal structures. These disorders are subclassified into TMJ articular disorders and masticatory muscle disorders. Patients with TMD most commonly present with pain, restricted or asymmetric mandibular motion, and TMJ sounds during mandibular movements. The prevalence tends to increase with age. Management of TMJ articular disorders consists of a combination of patient education, home-care plan, biobehavioral therapy, physical therapy, orthotic jaw appliance therapy, pharmacotherapy, and/or surgery. The goal is to increase function, reduce pain, and improve quality of life. Copyright © 2017 Elsevier Inc. All rights reserved.

    Injuries of the temporomandibular joint are mostly due to injuries or fractures of the mandibular condyle. Fractures of the skull base involving the temporomandibular joint are rare. Classification of fractures refers to their anatomical positions and the presence or absence of a luxation. Further, it is important whether the fracture is intra- or extra-capsular. The primary imaging method should be orthopantomography. As for therapy planning, especially surgery, also evaluation of soft tissue is necessary, computed tomography is the imaging method of choice. For diagnosis of complications or internal derangement of the temporomandibular joint, magnetic resonance imaging is to be recommended. (orig.) [German] Die Verletzungen des Kiefergelenks gehen zumeist mit einer Verletzung oder Fraktur des Kieferkoepfchens bzw. des Kiefergelenkfortsatzes einher. Frakturen der Schaedelbasis unter Beteiligung der Kiefergelenkpfanne sind selten. Unterschieden werden die Frakturen des Gelenkfortsatzes nach anatomischer Lokalisation und danach, ob eine Luxation vorhanden ist oder nicht. Weiter ist von Bedeutung, ob der Frakturspalt intraoder extrakapsulaer verlaeuft. Die primaere Bildgebung sollte mittels Orthopantomographie erfolgen. Da fuer eine weitere operative Behandlung auch die etwaige Verletzung der Weichteile von Bedeutung ist, bietet sich die Computertomographie als bildgebende diagnostische Methode an. Zur Abklaerung von Komplikationen bzw. des so genannten ''internal derangement'' ist die Magnetresonanztomographie zu empfehlen. (orig.)

    Dislocation of temporo-mandibular joint (TMJ) is an infrequent disease but still spectacular. This disease consists of a permanent, to some extent complete disruption of the temporo-mandibular joint. These dislocations often occur in a context of yawning, and less frequently after a burst of laughing or relatively mild facial trauma (slap, punch on the chin). We report a case of TMJ occurring in an uncommon circumstance: vaginal delivery. A woman aged 24-years with no special past medical history; primipara was admitted in the Department of Maternity of the University Hospital Hassan II of Fez for an imminent delivery of a twin pregnancy. Ten minutes after admission, the patient delivered vaginally with episiotomy. She gave birth to twins weighing 2800 g and 2400 g. During labour, and due to efforts of crying, the patient developed a sudden and immediate loss of function of the temporo-mandibular joint, with difficulty of speaking, the mouth permanently opened and with the chin lowered and thrown forward. The examination found an empty glenoid fossa of the temporo-mandibular joint in both sides. The diagnosis of dislocation of the TMJ was established. A CT scan of facial bones was done, objectifying a bilateral dislocation of TMJ. The reduction of this dislocation was performed in the operating room under sedation.

    To identify associations between clinical symptoms of temporomandibular joint disorders and radiographic findings. Two hundred four adult patients (156 women, 48 men, mean age 40 years) with temporomandibular joint (TMJ) pain/sounds or changes in mandibular motion were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Bilateral sagittal corrected TMJ tomograms in closed and open positions were assessed for the presence of flattening, erosion, osteophytes, and sclerosis in the joint components and the range of mandibular motion. Logistic regression analyses were performed with the radiographic findings as the dependent variables and the following clinical variables as independent variables: opening pattern, maximal jaw opening, TMJ sounds, number of painful muscle/TMJ sites, duration of pain, presence of arthritic disease, depression and somatization scores, graded chronic pain, and age and gender. Coarse crepitus on opening/closing (odds ratio [OR] > or = 3.12), on lateral excursions (odds ratio > or = 4.06), and on protrusion (OR > or = 5.30) was associated with increased risk of degenerative findings in tomograms. A clinical diagnosis of osteoarthritis increased the risk of radiographic findings (OR > or = 2.95) and so did increasing age (OR > or = 1.03 per year) and the female gender (OR > or = 2.36). Maximal assisted opening and maximal opening without pain (position (OR > or = 2.60). No other significant associations were observed. Age, gender, and coarse crepitus, but no pain-related variables, were associated with increased risk of degenerative findings in TMJ tomograms. Maximal opening < 40 mm was associated with a posterior condyle-to-articular tubercle relation on opening.

    Full Text Available The temporo-mandibular joint (TMJ it’s a joint closely related to the skull base, the spine, and the jaws; all these anatomical structures must be taken in consideration when evaluating pain involving the tmj. In order to detect patients affected by pathology or dysfunctions of the tmj, physical examination is of great value in orienting the diagnosis. Inspection must consider the symmetry of the body, the dental status and the type of occlusion. Palpation is a way to assess contractiont involving the muscles of the masticatory system and of the neck. Auscultation, based on articular noise provides means to determine whether we are dealing with degeneration of the joint or a dislocation of the intrarticular disc. In order to confirm the diagnosis obtained with the clinical evaluation, it’s useful to perform imaging techniques as opt, tomography and TC of the tmj and electromyokineosiography – index of the mandibular functionality and of the muscles status. MRI and dynamic MRI are among the non invasive exams which give the greatest amount of information, regarding the disc position and the joint degeneration. Arthroscopy is an invasive technique that allows early diagnosis of degeneration and is helpful to reveal early inflammatory processes of the joint.

    The optimal reconstruction of the mandible and of the temporo-mandibular joint after mandibular hemi-resection with disarticulation is still controversial in literature. This paperwork presents our experience on four cases in the reconstruction of the mandible together with the inferior arthroplasty of the temporo-mandibular joint, after the resection of extended benign tumors of the mandible, based on fibular free vascularized grafts having attached a Stryker titanium condylar prosthesis reconstructing the inferior segment of the temporo-mandibular joint. Our results for the this technique were excellent, with a functional rehabilitation very close to normal. After reviewing the various techniques and their arguments in literature, with accent on the TMJ reconstruction, we consider this method to be optimal for the reconstruction of mandibular defects in patients with neoplastic conditions.

    The most significant otologic symptoms, consisting of ear pain, tinnitus, dizziness, hearing loss and auricolar "fullness", generally arise within the auditory system, often are associated with extra auricolar disorders, particularly disorder of the temporo-mandibular joint. In our study we examined a sample of 200 consecutive patients who had experienced severe disabling symptom. The patiens came to maxillofacial specialist assessment for temporomandibular disorder. Each patient was assessed by a detailed anamnestic and clinical temporomandibular joint examination and they are divided into five main groups according classification criteria established by Wilkes; tinnitus and subjective indicators of pain are evaluated. The results of this study provide a close correlation between the joint pathology and otologic symptoms, particularly regarding tinnitus and balance disorders, and that this relationship is greater the more advanced is the stage of joint pathology. Moreover, this study shows that TMD-related tinnitus principally affects a younger population (average fifth decade of life) and mainly women (more than 2/3 of the cases). Such evidence suggests the existence of a specific tinnitus subtype that may be defined as "TMD-related somatosensory tinnitus".

    The stress and occlusion disturbance are very important etiologic factors in the temporomandibular joint (TMJ) pain dysfunction syndromes. Authors performed TMJ arthrograms in the patients with TMJ problem such as pain, click sound, limited motion and locking, etc. The following results noted: 1. The arthrographic findings of 22 TMJ were analyzed. a) Normal: 6 cases b) Anterior disc displacement with rediction: 6 cases · Early reduction: 2 cases · Intermediate reduction: 3 cases · Late reduction: 1 case c) Anterior disc displacement without reduction: 6 cases · Two cases had adhesion between the posterior portion of disc and the posterior surfaces of the articular eminence. 2. Among 22 cases, the clinical findings of 16 cases (73%) were compatible with arthrographic findings. 6 cases showed disparity between them.

    Nine patients with facial pain were evaluated with limited bone scans. The scintigrams correlated with microscopy in all patients, although radiographs correlated with microscopy in only five patients. The degenerative disease process in the temporomandibular joint was more extensive in the patients with radiographic and scintigraphic abnormalities than in those with scintigraphic abnormalities alone. The limited bone scan appears useful in detecting early degenerative changes in the temporomandibular joint

    This study was designed to investigate the efficacy of the temporomandibular joint arthrocentesis with and without injection of sodium hyaluronate (SH) in the treatment of temporomandibular joint disorders. A total of sixty two TMJs in 34 males and 28 females aged 20-65 years comprised the study material. The patients' complaints were limited mouth opening, TMJ pain, and joint noises during function. Patients were randomly divided into 2 groups in which arthrocentesis plus intra-articular injection of sodium hyaluronate was performed in 1 group and only arthrocentesis was performed in the other group. Both groups contained patients with disc displacement with reduction and without reduction. Clinical evaluation of the patients was done before the procedure, immediately after the procedure, at 1 week and 1, 3 and 6 months postoperatively. Intensity of TMJ pain was assessed using visual analog scales. Maximal mouth opening and lateral jaw movements also were recorded at each follow-up visit. Both techniques increased maximal mouth opening, lateral movements, and function, while reducing TMJ pain and noise. Although patients benefitted from both techniques, arthrocentesis with injection of SH seemed to be superior to arthrocentesis alone.

    The temporomandibular joint(TMJ) is really a complex of two synovial space separated by fibrocartilaginous disc. Single inferior joint space arthrography is commonly performed for evaluation of TMJ disorders, which is known to be superior in demonstrating joint dynamics. But it reveals only the inferior surface of the disc. Therefore, dual space arthrography is superior to demonstrate the soft tissue anatomic feature of the joint such as disc position and shape. Authors performed 83 TMJ arthrograms in TMJ problems. Initially, the inferior joint space was done and then the superior space was sequentially contrasted. The follow results were noted: 1. In all cases, dual space arthrography revealed accurate disc shape and positions. 2. Concordant findings between the two techniques: 68 cases (82%). Discordance between the two techniques: 15 cases (18%) 3. Possible causes of discordance between inferior and dual space arthrography. a) Normal varians of anterior recess: 3 cases b) Posterior disc displacement: 4 cases c) Influence of the patient's head position change :4 cases d) False perforation: 2 cases e) Reduction change: 2 cases 4. In 5 cases with anterior displacement, dual space arthrography gave additional findings such as adhesion within the superior space, which could not be evaluated by single inferior space.

    Several diseases should be considered in the differential diagnosis of disorders affecting the temporomandibular joints. Internal derangement is the main condition responsible for pain related to this joint. Clinical signs may, though, be quite non-specific, and many other conditions present with similar and not infrequently indistinguishable signs and symptoms. In the present study, the authors describe several non-dysfunctional conditions affecting the temporomandibular joints through computed tomography and magnetic resonance imaging, emphasizing the importance of these imaging methods in the diagnosis of inflammatory, neoplastic and traumatic diseases of this region. Considering that clinical presentations are frequently non-specific, radiologists play a critical role in the differential diagnosis. (author)

    Full Text Available Existen disímiles condiciones que hacen necesario el reemplazo articular temporomandibular; dentro de las más frecuentes se encuentran la anquilosis, la osteoatrosis, estadíos avanzados del Síndrome de disfunción temporomandibular, daño articular postrauma y procesos neoplásicos o tumorales. Los queratoquistes odontógenos que se agrupan para su estudio dentro de los quistes odontogénicos del desarrollo, representan cerca del 7 al 10 por ciento de todos los quistes maxilo-mandibulares. Se dice que tienen dos picos de incidencia entre la segunda y tercera década de vida y entre los 50 y 60 años de edad, con una ligera predilección por el sexo masculino. Aparece más frecuentemente en la región del tercer molar de la mandíbula con extensión a la rama ascendente El presente trabajo tuvo como objetivo mostrar el caso de un paciente masculino de 57 años de edad en el que fue necesario el reemplazo articular temporomandibular debido a un queratoquiste odontogénico que involucraba la totalidad de la rama mandibular derecha, incluyendo el proceso condíleo y coronoideo, así como el ángulo hasta el tercio posterior del cuerpo mandibular. Tras un año de realizada la intervención quirúrgica la evolución del paciente fue satisfactoria.Temporomandibular joint replacement is required in a variety of conditions. Among the most frequent are ankylosis, osteoarthrosis, advanced stages of the temporomandibular dysfunction syndrome, post-traumatic joint damage, and neoplastic or tumoral processes. Odontogenic keratocysts, which are classified as developmental odontogenic cysts for study purposes, constitute 7-10 per cent of all maxillomandibular cysts. Two peaks have been identified in their incidence: between the second and third decades of life, and between 50 and 60 years of age, with a slight predominance of the male sex. They are most common in the third molar area of the mandibule, with expansion to the ascending branch. A case is

    Computed tomography (CT) of the temporomandibular joint (TMJ) was compared with hypocycloidal tomography in 30 joints of 15 adults with rheumatic disease. CT included 1.5 mm thick axial scans (at 1.0 mm intervals) with reformatted oblique sagittal and oblique coronal sections. Multisection (at 2.0 mm intervals) tomography included oblique sagittal and occasionally, oblique coronal sections. CT demonstrated bone abnormalities in 21 and tomography in 20 joints, indicating high agreement between the imaging modalities regarding number of abnormal TMJs. Bone structures were, however, better visualized by multiplanar CT due to superior contrast and spatial resolution particularly in the most lateral and medial parts of the joint, indicating superiority of CT for depicting subtle bony TMJ abnormalities in patients with rheumatic disease.

    We retrospectively reviewed the MRI findings of 100 temporomandibular joints in 78 patients who had complained temporomandibular joint dysfunction. MRI findings were classified according to Wilke's staging criteria. And these findings were compared with arthographic findings in 22 joint and surgical findings in 44 joints. According to Wilke's staging, they were classified into 6 stages of abnormality: stage 0 (33 cases), stage I (19 cases), stage II (10 cases), stage III (18 cases), stage IV (6 cases), stage V (14 cases). Among the 22 cases in which arthography and MRI were done, both studies were well correlated in 10 joints. In 7 joints, MRI was superior to arthography, which correctly demonstrated the meniscal displacement in 2 joints and meniscal deformity in 5 joints. In 5 joints, arthography was superior to MR, which demonstrated the perforation (1 joint), adhesion (2 joints) and recapture of meniscus (2 joints). Compared with surgical findings, MRI correctly demonstrated the displacement of meniscus in all 44 joints. However, in case of the 10 meniscal perforation, MRI demonstrated the meniscal discontinuity in only 4 joints. Retrospective MR findings in 10 proven cases were the defect in posterior attachment in 4, far anterior meniscal displacement without recapture in 8, condylar spur in 4, and close bone to bone contact in 1. In conclusion, MRI as a primary diagnostic modality of temporomandibular joint derangement, is superior for the grading of displacement and deformity of meniscus but inferior for the evaluation of perforation, adhesion and recapture of meniscus to conventional arthrography. In case of the suspected meniscal perforation, arthrographic correlation is recommended preoperatively

    One hundred temporo-mandibular joints were examined with a super-conducting nuclear resonance tomograph (1.0 Tesla) using various high resolution surface coils. The optimal method proved to be a spin echo sequence with a repetition time of 1,000 msec and an echo period of 28 msec with a 4 mm slice width. There were significant advantages from the non-invasive MRT diagnosis of the temporo-mandibular joints when compared with CT and with arthrography in recognising abnormal discs, changes in the tissues and for post-operative control.

    The radiographic anatomy of the normal temporomandibular joint in newborns and children up to 4 years of age was investigated, partly on specimens, obtained at autopsy, with methods corresponding to clinical procedures, and partly on patients. A rather flat mandibular fossa and immature mandibular head were found at birth, whereas a well-developed articular tubercle and an adult-like radiographic appearance of the joint were found at about one year of age. No evident changes of the radiographic anatomy seemed to occur from one to 4 years of age. A striking similarity was observed between the dystrophic temporomandibular joint in patients with juvenile rheumatoid arthritis and micrognathia and the normal radiographic appearance in the first months of life, indicating an early involvement of this joint in patients developing micrognathia.

    Temporomandibular joint is one of the most complicated joints of the body and plays an important role in the head and neck system. One of the factors affecting the temporomandibular joint and lead to temporomandibular disorder is anxiety with all the events causing it. The aim of this study was to determine a relationship between anxiety and temporomandibular disorders. In this prospective study, subjects were randomly selected. One hundred and thirty pre-university students in Isfahan were evaluated with Ketel's test of anxiety, exam stress test and temporomandibular disorder questionnaires. The evaluation was done in two stages 10 months and 1 month prior to the university entrance exam (Konkour), clinical assessments consisted of masticatory muscles and sternocleidomastoid muscle palpation, temporomandibular joint palpation for pain and noise and its movement, and mouth opening limitations. The Wilcoxon rank test and paired t-test were used to analyze the data and the P value under 0.05 was considered significant. The level of anxiety and occurrence of temporomandibular disorders were increased between two stages and had the highest level in the second stage. There was a significant increase between two stages (Ptemporomandibular disorders and anxiety between the two stages can suggest a possible relationship between anxiety and temporomandibular disorders. Therefore, the effect of anxiety in triggering temporomandibular disorder symptoms is probable.

    Full Text Available Dislocation of temporo-mandibular joint (TMJ is an infrequent disease but still almost spectacular. This disease consists of a permanent, to some extent complete disruption of the temporo-mandibular joint. These dislocations often occurs in a context of yawning, and less frequently after a burst of laughing or relatively mild facial trauma (slap, punch on the chin.We report a case of TMJ occurring in an uncommon circumstance : vaginal delivery. A young woman aged 24-years with no special past medical history; primipara was admitted in the Department of Maternity of the University Hospital Hassan II of Fez for an imminent delivery of a twin pregnancy. Obstetrical analgesia was not possible so the parturient cried in a strong manner during labour. Ten minutes after admission, the patient delivered vaginally with episiotomy. She gave birth to twins weighing 2800g and 2400g. During labour, and effort of crying, the patient presented a sudden and immediate loss of function of the temporo-mandibular joint, with difficulty of speaking, the mouth permanently opened, with the chin lowered and thrown forward. The examination found an emptiness of the glenoid fossa of the temporo-mandibular joint in both sides. The diagnosis of dislocation of the TMJ has established. Performance of special radiologic screening to study the TM was technically not possible. A CT scan of facial bones has been achieved so objectifying a bilateral dislocation of TMJ. The reduction of this dislocation was performed in the operating room under sedation

However, little attention has been paid to temporomandibular joint disk abnormalities. To assess combinations of MRI findings in the symptomatic temporomandibular joint in children with juvenile idiopathic arthritis with focus on disk abnormalities. This was a retrospective study of 46 patients with juvenile idiopathic arthritis, mean age 12 years (range: 5-17 years). Mean disease duration was 70 months (standard deviation: 61 months). MR images of 92 temporomandibular joints were scored for thickness of abnormally enhancing synovium (synovitis), joint effusion, bone marrow oedema, abnormal bone shape, bone erosion and disk abnormalities. The 92 temporomandibular joints were categorized as A: No synovitis and normal bone shape (30/92; 33%), B: Synovitis and normal bone shape (14/92: 15%), C: Synovitis and abnormal bone shape (38/92; 41%) and D: No synovitis but abnormal bone shape (10/92; 11%). Thirty-six of the 46 patients (78%) had synovitis and 33/46 (72%) had abnormal bone shape, most frequently in combination (30/46; 65%). Disk abnormalities (flat disk, fragmented disk, adherent disk and displaced disk) were found in 29/46 patients (63%). Disk abnormalities were found in all categories of juvenile idiopathic arthritis involved temporomandibular joints (B: 8/14 [57%]; C: 25/38 [66%] and D: 7/10 [70%]). Disk displacement was found in half of the joints (7/14) in category B. Synovitis was most pronounced in this category. Disk abnormalities were frequent. Disk displacement also occurred in joints with early temporomandibular joint arthritis, i.e., with normal bone shape. Other disk abnormalities were found in joints with bone abnormalities.

    The occurrence of temporo-mandibular joint (TMJ) disease in ankylosing spondylitis is not widely recognized and its incidence is disputed. Seventy-nine patients attending two routine rheumatology clinics were therefore examined by dental surgeon and nine (11-5 per cent) were considered to have specific TMJ involvement. These patients were older than the remainder, and had more extensive spinal and peripheral joint disease. Symptoms were mild and the predominant clinical feature was restricted mouth opening, which could present considerable difficulties during emergency anaesthesia. Bilateral condylectomy was undertaken in one patient with some benefit. Images PMID:1124959

    Full Text Available The temporomandibular joint (TMJ is an articulation formed between the temporal bone and the mandibular condyle which is commonly affected. These affections are often so painful during fundamental oral activities that patients have lower quality of life. Limitations of therapeutics for severe TMJ diseases have led to increased interest in regenerative strategies combining stem cells, implantable scaffolds and well-targeting bioactive molecules. To succeed in functional and structural regeneration of TMJ is very challenging. Innovative strategies and biomaterials are absolutely crucial because TMJ can be considered as one of the most difficult tissues to regenerate due to its limited healing capacity, its unique histological and structural properties and the necessity for long-term prevention of its ossified or fibrous adhesions. The ideal approach for TMJ regeneration is a unique scaffold functionalized with an osteochondral molecular gradient containing a single stem cell population able to undergo osteogenic and chondrogenic differentiation such as BMSCs, ADSCs or DPSCs. The key for this complex regeneration is the functionalization with active molecules such as IGF-1, TGF-β1 or bFGF. This regeneration can be optimized by nano/micro-assisted functionalization and by spatiotemporal drug delivery systems orchestrating the 3D formation of TMJ tissues.

    Until recently, CT investigation of temporomandibular joint (TMJ) disorders has been regarded as a sophisticated procedure. A method of investigation was developed that allows easy evaluation of axial scans. The method was evaluated in a series of 65 joints with arthrographically diagnosed internal derangements. In anterior disk displacement CT findings led to an identical diagnosis in 56 of 65 joints (sensitivity, 86%). In clinically asymptomatic joints investigated for other reasons, only one of 12 showed signs of internal derangement on CT (specificity, 92%). This conservative approach to CT evaluation of internal derangement seems to be as accurate as more sophisticated methods. It is easy to perform, requires no additional manpower or computer time, and has a very good reproducibility

    Thirty-nine patients (forty-four joints) who had been diagnosed as having meniscus perforation of the temporomandibular joint by inferior joint space arthrography and had been treated by surgical procedures were evaluated retrospectively. Information of clinical findings, arthrotomographic findings and surgical findings was collected on a standardized form and evaluated. The results were as follows: 1. On the 34 patients of 38 joints which were surgically confirmed perforation of meniscus or its attachments of the temporomandibular joint, there were 29 females and 5 males (5.8:1). The average age was 36 years (range 17 to 70). 2. The common clinical findings of group that had meniscus displacement without reduction and with perforation were pain on the affected joint and limitation of mouth opening. In the group showing meniscus displacement with reduction and with perforation the common clinical findings were pain and clicking on the affected joint. 3. 32 joints (84.2%) were arthrotomographically anterior meniscus displacement without reduction and with perforation, 6 joints (15.8%) showed anterior meniscus displacement with reduction and with perforation. 4. Joints categorized arthrotomographically as having meniscus displacement without reduction and with perforation were less likely to have full translation of the condyle in comparison with the normal or meniscus displacement with reduction and with perforation groups (p<0.05) 5. The arthrographic findings of 44 joints having meniscus perforation were compared with surgical findings, there were 6 false positive findings of meniscus perforation, the reliability of arthrographic findings of meniscus perforation was a 86.4% correlation with surgical findings. 6. On the site of perforations of 38 joints which were surgically confirmed perforation of meniscus or its attachments, twenty-three of perforations (60.5%) were in location at the junction of the meniscus and posterior attachment, fourteen (36.9%) were

    The term "juvenile idiopathic arthritis" (JIA) encompasses a group of arthritis of unknown cause with onset before the age of 16 years that last for at least 6 weeks. The prevalence of temporomandibular joint involvement in published series ranges from 17% to 87%. Temporomandibular joint involvement is difficult to detect clinically, so imaging plays a key role in diagnosis and monitoring treatment. MRI is the technique of choice for the study of arthritis of the temporomandibular joint because it is the most sensitive technique for detecting acute synovitis and bone edema. Power Doppler ultrasonography can also detect active synovitis by showing the hypervascularization of the inflamed synovial membrane, but it cannot identify bone edema. This article describes the MRI technique for evaluating the temporomandibular joint in patients with juvenile idiopathic arthritis, defines the parameters to look for, and illustrates the main findings.

    The purpose of this study was to quantitatively evaluate contrast enhancement effects of the posterior disk attachment in the temporomandibular joint arthrosis using dynamic MRI with bilateral surface coils. One hundred twenty-four temporomandibular joints in 96 symptomatic patients and 27 control subjects were examined with a spoiled GRASS pulse sequence (TR: 35 ms, TE: 8 ms, flip angle: 60deg). One sagittal scan was performed prior to injection, then 0.1 mmol/kg of Gd-DTPA was given as a rapid bolus injection, immediately after which scans were performed at 30 seconds intervals for a period of 5 minutes. Signal intensity (SI) was measured from the ROI of the posterior disk attachment region. The contrast enhancement effects may be calculated by SI ratio (SIR) = ( SI post -SI pre )/SI pre , where SI post and SI pre were the signal intensities after and before administration of contrast medium. The time intensity curve of SIR versus time after injection was obtained on each symptoms. Join pain group (85 joints) tended to show a rapid enhancement pattern, while control group (54 joints), joint sound or opening limitation group (39 joints), and asymptomatic group (68 joints) showed a relatively gradual enhancement pattern. The drop of SIR in four groups were hardly observed during examination. Mean peak SIR of control group, joint pain group, joint sound or opening limitation group, and asymptomatic group was 0.62±0.24 (SD), 1.53±0.69, 0.73±0.38 and 0.78±0.44 respectively. The mean SIR of pain group was significantly (P<0.001, t-test) higher than that of other groups. These results suggested that dynamic MRI of the temporomandibular joint may effectively depict the inflammatory changes of the posterior disk attachment. (author)

    A rapidly increasing number of mandibular condylar fractures and some complications related to injuries of temporomandibular elements make this study important. Intra-articular disorders lead to secondary pathological findings such as osteoarthritis, deforming osteoarthrosis, and temporomandibular joint ankylosis that limits mouth opening, mastication, swallowing, breathing, and decreased/lost working capacity or disability. Early diagnosis of intra-articular disorders can prevent from long-lasting functional complications caused by temporomandibular joint injuries. This study was performed for the purpose of early detection and investigation of organic pathological changes in the cartilaginous and osseous tissues of the temporomandibular joint caused by traumatic fractures of the mandibular condyle. Twenty patients underwent a general clinical examination, magnetic resonance imaging (MRI), and immune-enzyme testing for biochemical markers of connective tissue injury (pyridinoline and deoxypyridinoline) in urine. Disk dislocation, deformation, adhesion, perforation or squeeze, tension or disruption of ligaments, and injury of articular surfaces are among complications of mandibular fractures that can be revealed on MRI. As regards biochemical findings, we revealed a sharp rise in the levels of pyridinoline and deoxypyridinoline before treatment and a lack of stabilization within 21 days of treatment.

    The author analysed the bone changes, the positional relationships between condylar head and articular fossa, and the interrelationship between the bone changes and the abnormal position of condylar head, from 1,036 radiographs of 259 patients with temporomandibular joint arthrosis, which were obtained by the oblique-lateral transcranial projection and orthopantomograms. The results were as follows: 1. Among the radiographic bone changes of the temporomandibular joint arthrosis, deformity was 36..90% (217 cases), sclerosis 34.18% (201 cases), erosive change 25.58% (152 cases) and marginal proliferation 3.06% (18 cases) respectively. 2. In the positional changes between condylar head and articular fossa, the downward positioning of condylar head in centric occlusion was most frequent (36.90%), of which frequency was significantly higher than forward positioning (11.22%) and backward positioning (4.76%) in same condition. Also, radiographs showed that the enlargement of articular space showed higher frequency than its narrowing. In the opening position of mouth, the restrict ed movement of condylar head within articular fossa was most frequent (35.03%). The forward positioning and the downward positioning was 15.65% and 9.52% respectively. Also, radiographs revealed that the incomplete movement or no positional change of condylar head was most frequent. 3. In the interrelationship between bone changes and abnormal position of condylar head, deformity was 42.79% in the cases of downward positioning of condylar head in centric occlusion and 37.50% in those of normal positioning of condylar head in same condition. This revealed that deformity was most frequent bone change in above condylar positionings. However, erosive change was 34.62% in the cases of downward positioning of condylar head in centric occlusion and 33 .33% in those of forward positioning. In opening position of condylar head, and deformity in the cases of norma l positioning, forward positioning and

    The three-dimensional (3D) temporomandibular joint (TMJ) model derives from a study of the cranium by 3D virtual reality and mandibular function animation. The starting point of the project is high-fidelity digital acquisition of a human dry skull. The cooperation between the maxillofacial surgeon and the cartoonist enables the reconstruction of the fibroconnective components of the TMJ that are the keystone for comprehension of the anatomic and functional features of the mandible. The skeletal model is customized with the apposition of the temporomandibular ligament, the articular disk, the retrodiskal tissue, and the medial and the lateral ligament of the disk. The simulation of TMJ movement is the result of the integration of up-to-date data on the biomechanical restrictions. The 3D TMJ model is an easy-to-use application that may be run on a personal computer for the study of the TMJ and its biomechanics.

    Full Text Available Temporomandibular joint dysfunction with clicking symptom is sound “click” when open and close the mouth. The purpose of this study was to obtain the description of the frequency of temporomandibular joint dysfunction with clicking symptom caused by premature loss of primary molar teeth in children aged 6-12 years old at SDIT Imam Bukhari. The study was a descriptive survey, 136 students as samples were taken by purposive sampling technique. Premature loss of primary molar teeth examined by checking up the first and second primary molars upper and lower jaw using the hand mirror and explorer. Temporomandibular joint dysfunction examined by palpation and using a stethoscope. The result of this study showed that from 136 students having premature loss there are 49 students (36,03% had temporomandibular joint dysfunction with clicking symptom. The conclusion of this study indicates that more than one-fourth students at SDIT Imam Bukhari with premature loss of primary molar teeth had temporomandibular joint dysfunction with clicking symptom.

    We conducted a genetic analysis of the developing temporo-mandibular or temporomandi-bular joint (TMJ), a highly specialized synovial joint that permits movement and function of the mammalian jaw. First, we used laser capture microdissection to perform a genome-wide expression analysis of each of its developing components. The expression patterns of genes identified in this screen were examined in the TMJ and compared with those of other synovial joints, including the shoulder and the hip joints. Striking differences were noted, indicating that the TMJ forms via a distinct molecular program. Several components of the hedgehog (Hh) signaling pathway are among the genes identified in the screen, including Gli2, which is expressed specifically in the condyle and in the disk of the developing TMJ. We found that mice deficient in Gli2 display aberrant TMJ development such that the condyle loses its growth-plate-like cellular organization and no disk is formed. In addition, we used a conditional strategy to remove Smo, a positive effector of the Hh signaling pathway, from chondrocyte progenitors. This cell autonomous loss of Hh signaling allows for disk formation, but the resulting structure fails to separate from the condyle. Thus, these experiments establish that Hh signaling acts at two distinct steps in disk morphogenesis, condyle initiation, and disk-condyle separation and provide a molecular framework for future studies of the TMJ.

    To report the temporo-mandibular joint (TMJ) kinetics and masticatory function in healthy children. Temporo-mandibular joint palpation and electrognathographic registrations of chewing cycles were repeated for 3 years in order to evaluate changes. Healthy children without systemic pathologies, decayed cavities and previous dental treatment. Electrognathographic (EGN) registration of masticatory cycles and TMJ palpation were carried out on 52 patients (mean age: 5 years 8 months, range: 5 years 1 month, 6 years 8 months), by two university researchers, once a year for 3 consecutive years. TMJ palpation, differentiated TMJ synchronism (simultaneous bilateral opening movement) and TMJ asynchronism (not simultaneous bilateral opening movement), TMJ subluxation and click were observed. Electrognathographic registrations differentiated normal and abnormal jaw chewing cycles, and narrow and large cycles. Temporo-mandibular joint asynchronism was evident in 34 of 52 patients in the primary dentition, in 42 of 52 patients after the eruption of the first permanent molar, and in 31 of 52 patients after the eruption of the permanent incisors. TMJ subluxation increased during the full period of observation. Three temporomandibular clicks appeared after the eruption of the permanent incisors. Altered mastication was not always associated with TMJ disorders. In children, normal chewing cycles can coexist with occlusal discrepancies, cranio-facial growth and TMJ alterations.

    Ten temporomandibular joints (TMJs) of 5 healthy volunteers and 19 TMJs of internal derangements in 16 patients with splint therapy were examined with MR imaging. T1-weighted images were obtained only in the closed mouth position, and gradient recalled acquisition in steady state (GRASS) images were obtained in active opening and closing phases, allowing a pseudodynamic display of TMJ movement. All patients received protrusive splint treatment. The usefulness of MR imaging to assess the efficacy of splint therapy was evaluated. Corrected disk position with the splint in place was clearly demonstrated in 9 TMJs, corresponding with elimination of reciprocal clicking. Ten other TMJs of anterior disk displacement without reduction showed uncorrected disk position by the splint. This information could confirm the therapeutic efficacy, or suggest other treatment alternatives. GRASS MR imaging can provide accurate and physiologic information about disk function in initial and follow-up assessment of protrusive splint therapy. (orig.)

    Temporomandibular joint syndrome, or Costen syndrome, is a clinically diagnosed disorder whose most common symptoms include joint pain and clicking, difficulty opening the mouth, and temporomandibular joint discomfort. The temporomandibular joint (TMJ) is supplied by the auriculotemporal nerve, a collateral branch of the mandibular nerve (the V3 branch of the trigeminal nerve). The aim of this study is to assess the effectiveness and safety of permanent peripheral nerve stimulation to relieve TMJ pain. This case series is a prospective study. Pain Unit of a regional universitary hospital. The study included 6 female patients with temporomandibular pain lasting from 2 to 8 years that did not respond to intraarticular local anesthetic and corticoid injections. After a positive diagnostic block test, the patients were implanted with quadripolar or octapolar leads in the affected preauricular region for a 2-week stimulation test phase, after which the leads were connected to a permanent implanted pulse generator. Results of the visual analog scale, SF-12 Health Survey, Brief Pain Inventory, and drug intake were recorded at baseline and at 4, 12, and 24 weeks after the permanent implant. Five out of 6 patients experienced pain relief exceeding 80% (average 72%) and received a permanent implant. The SF-12 Health Survey results were very positive for all specific questions, especially items concerning the physical component. Patients reported returning to normal physical activity and rest at night. Four patients discontinued their analgesic medication and 1 patient reduced their gabapentin dose by 50%. Sample size; impossibility of placebo control. Patients affected with TMJ syndrome who do not respond to conservative treatments may find a solution in peripheral nerve stimulation, a simple technique with a relatively low level of complications.

    The purpose of the present review is to systematically and critically analyze the available literature regarding the importance, applicability, and practicality of (MRI), computerized tomography (CT) or cone-beam CT (CBCT) image registration for TMJ anatomy and assessment. A systematic search of 4 databases; MEDLINE, EMBASE, EBM reviews and Scopus, was conducted by 2 reviewers. An additional manual search of the bibliography was performed. All articles discussing the magnetic resonance imaging MRI and CT or CBCT image registration for temporomandibular joint (TMJ) visualization or assessment were included. Only 3 articles satisfied the inclusion criteria. All included articles were published within the last 7 years. Two articles described MRI to CT multimodality image registration as a complementary tool to visualize TMJ. Both articles used images of one patient only to introduce the complementary concept of MRI-CT fused image. One article assessed the reliability of using MRI-CBCT registration to evaluate the TMJ disc position and osseous pathology for 10 temporomandibular disorder (TMD) patients. There are very limited studies of MRI-CT/CBCT registration to reach a conclusion regarding its accuracy or clinical use in the temporomandibular joints.

    The purpose of this study was to prove the relationship between arthrographic and clinical features in temporomandibular joint disorders. In order to carry out this study, ninety-eight arthrographic examinations of temporomandibular joints were performed in eighty-two patients who had the temporomandibular joint disorders. As the arthrographic examination, the cases were classified in three groups, disk displacement with reduction, disk displacement without reduction, within normal limit. After this, the cases were clinically examined, and the results were compared and analyzed in each other group. The obtained results were as follows ; 1. As the classification by arthrographic examination, three groups (disc displacement with reduction, disc displacement without reduction, within normal limit) were 41%, 54%, 5% of total cases in this study, respectively. 2. The third decade (65%) was most frequent in this study. The average age of each group (disc displacement with reduction, disc displacement without reduction, within normal limit) was 24, 28, 21, and disc displacement without reduction group was higher than any other group. 3. In the chief complaint, pain was the most frequent in all three groups. Joint sound was also frequent in disc displacement with reduction group, but in disc displacement without reduction group, limitation of mouth opening was more frequent. 4. Of the various pain, the movement pain was most frequent (61%) in this study. In joint sound, click (63%) was the most frequent in disc displacement with reduction group, but sound history (42%) and no sound (31%) were more frequent in disc displacement without reduction group. 5. The average maximum opening of each group (disc displacement with reduction, disc displacement without reduction, within normal limit) was 44 mm, 32.9 mm, 44 mm, and disc displacement without reduction group was less than any other group. 6.

    Temporo-Mandibular Joints (TMJ) and orthognathic surgery are closely linked. In the past, some authors have even described (with mixed results) the correction of some dysmorphosis through direct procedures on the TMJs. Nowadays, performing orthognathic surgery involves the TMJ in three different occasions: (1) TMJ disorders potentially responsible for dento-maxillary dysmorphosis, (2) effects of orthognathic surgery on TMJs, and (3) condylar positioning methods in orthognathic surgery. These three chapters are developed in order to focus on the close relationships between TMJ and orthognathic surgery. Some perspectives close this article. Copyright © 2016 Elsevier Masson SAS.

    Virtually all the articles in literature addressed only a specific type of dislocation. The aim of this review was to project a comprehensive understanding of the pathologic processes and management of all types of dislodgement of the head of the mandibular condyle from its normal position in the glenoid fossa. In addition, a new classification of temporomandibular joint dislocation was also proposed. A thorough computer literature search was done using the Medline, Cochrane library and Embase database. Key words like temporo-mandibular joint dislocation were used for the search. Additional manual search was done by going through published home-based and foreign articles. Case reports/series, and original articles that documented the type of dislocation, number of cases treated in the series and original articles. Treatment done and outcome of treatment were included in the study. A total of 128 articles were reviewed out which 79 were found relevant. Of these, 26 were case reports, 17 were case series and 36 were original articles. 79 cases were acute dislocations, 35 cases were chronic protracted TMJ dislocations and 311 cases were chronic recurrent TMJ dislocations. Etiology was predominantly trauma in 60% of cases and other causes contributed about 40%. Of all the cases reviewed, only 4 were unilateral dislocation. Various treatment modalities are outlined in this report as indicated for each type of dislocation. The more complex and invasive method of treatment may not necessarily offer the best option and outcome of treatment, therefore conservative approaches should be exhausted and utilized appropriately before adopting the more invasive surgical techniques.

    Full Text Available Background: Ankylosis of the temporomandibular joint (TMJ is an intracapsular union of the disc-condyle complex to the temporal articular surface that restricts mandibular movements, including the fibrous adhesions or bony fusion between condyle, disc, glenoid fossa, and eminence. It is a serious and disabling condition that may cause problems in mastication, digestion, speech, appearance, and hygiene. Case Report: This report describes a case of a 12-year-old girl with inability to open her mouth, diagnosed with unilateral right bony TMJ ankylosis. The surgical approach consisted of gap arthroplasty with interpositional temporalis muscle flap followed by vigorous physiotherapy. Conclusion: The treatment of TMJ ankylosis poses a significant challenge because of technical difficulties and a high incidence of recurrence. Its treatment includes the orthodontist, oral and maxillofacial surgeon, pediatric dentist, and psychologist and physical therapist as part of the healthcare team.

    To evaluate the clinical effect of joint reconstruction by using autogenous coronoid process graft to treat temporomandibular joint(TMJ) ankylosis. Nine cases of TMJ ankylosis from September 2008 to September 2010 were surgically treated by joint reconstruction with autogenous coronoid process graft, using autogenous articular disc or prosthodontic membrane as interpositional material. Mouth opening, occlusion and cone beam CT(CBCT) were used for evaluation before and after surgery. Satisfactory mouth opening was achieved in all patients and no one got occlusal changes or reankylosis during follow-up. CBCT showed that coronoid process graft reached bone union with the ramus and turned to be round. It is effective to cure TMJ ankylosis through joint reconstruction with autogenous coronoid process graft.

    Anterior disc displacement (ADD) of temporomandibular joint (TMJ) is regarded as one of the major findings in temporomandibular disorders (TMD). It is related to joint noise, pain, mandibular dysfunction, degenerative change and osteoarthritis. In the mean time, the pathological changes were found in synovial membrane and synovial fluid. Hyaluronic acid is a principal component of the synovial fluid which plays an important role in nutrition, lubrication, anti-inflammation and cartilage repair. The synthesis, molecule weight, and concentration of hyaluronic acid are decreased during TMD and cause TMJ degenerative changes. The clinical conditions, pathological changes, the mechanism of action for hyaluronic acid and the treatment of anterior disc displacement of TMJ are discussed in this article.

    This report is a retrospective study of fluid extravasation as a complication of temporomandibular joint pumping and perfusion. Contrast-enhanced 3D-CT of the upper joint compartment was performed for presurgical diagnosis before temporomandibular joint arthroscopic surgery in our hospital from 1996 to 2000. From these cases, 43 joints and 38 patients were selected because they had not improved under conservative treatment during the previous six months. Fluid extravasation of the articular capsule was recognized in 9 joints (20.9%) in 9 patients, 3 males and 6 females. Two of the nine patients had undergone arthroscopic observation before surgery. This test had revealed only thin articular capsule, not a perforation, in any of these cases. The data indicate only extremely tiny perforations or infiltration leakage due to the fluid pressure in the upper joint compartment during pumping or perfusion. Oral and maxillofacial surgeons should be aware of this complication. (author)

    Full Text Available Temporomandibular joint disorders are disturbances of mastication system due to one or more component of mastication system does not properly function. The factors that play a role in this problem divided into three factors; a predisposition factor (systemic, occlusion disturbances and psychological trouble, b initiation factor (traumatic and c perpetuation factor (social behavior. These disorders are able to cause a variety of symptom suck as limitedness of jaw movement, clicking, deviation locked joint, muscle pain, joint pain, jaw movement pain and pain of ear and headache. The objective of this study was to obtain information about the prevalence degree of severity of the temporomandibular joint disorder, the differences of prevalence between man and woman and the different among age groups. The study was descriptive and analysis survey, done to 134 patients as an experimental sample of 3–75-year old that have visited Dental Hospital, Padjadjaran University Bandung, during February 2008. Sample consist of 57 men and 77 women were evaluated by using Helkimo Index and analysis by using Z statistical proportion test to know the existence of difference prevalence degree of severity between man and woman and using the chi-square test to know the difference prevalence among age groups.The result of this study shows that there is highly prevalence severity of temporomandibular joint disorder (84,33% and significantly different on prevalence severity between man and woman and among a group of ages.The conclusion can be drawn that patients who visited the dental hospital, Padjadjaran University have higher prevalence severity of temporomandibular joint disorder where a woman has higher level compare to man, and the young adult group has highest either man and woman. Clicking is the most often symptom appear to man and woman.

    Tinnitus is frequently associated with temporomandibular joint (TMJ) dysfunction. However, the nature of the relationship is not fully understood. Here the authors compared 30 patients with a confirmed diagnosis of temporomandibular joint dysfunction and tinnitus to a group of 61 patients with tinnitus but without any subjective complaints of TMJ dysfunction with respect to clinical and demographic characteristics. Case-control study. Tertiary referral center. Tinnitus patients with and without TMJ dysfunction presenting at the Department of Prosthetic Dentistry and th: Tinnitus Clinic at the University of Regensburg. Tinnitus patients with TMJ disorder had better hearing function (P neck movements (P = .001). Classical risk factors for tinnitus (age, male gender, hearing loss) are less relevant in tinnitus patients with TMJ disorder, suggesting a causal role of TMJ pathology in the generation and maintenance of tinnitus. Based on this finding, treatment of TMJ disorder may represent a causally oriented treatment strategy for tinnitus.

    Synovial chondromatosis (SC) is an uncommon disease characterized by a benign nodular cartilaginous proliferation arising from the joint synovium, bursae, or tendon sheaths. Although the temporomandibular joint is rarely affected by neoplastic lesions, SC is the most common neoplastic lesion of this joint. The treatment of this disease consists in the extraoral surgery with a wide removal of the lesion; in this study, the authors described a more conservative intraoral surgical approach. Patient with SC of temporomandibular joint typically refer a limitation in the mouth opening, together with a persistent not physiological mandibular protrusion and an appearance of a neoformation located at the right preauricular region: the authors reported 1 scholar patient. After biopsy of the neoformation, confirming the synovial chondromatosis, the patient underwent thus to the surgical excision of the tumor, via authors' conservative transoral approach, to facilitate the enucleation of the neoformation. The mass fully involved the pterygo-maxillary fossa with involvement of the parotid lodge and of the right TMJ: this multifocal extension suggested for a trans-oral surgical procedure, in the light of the suspicion of a possible malignant nature of the neoplasm. Our intraoral conservative approach to surgery is aimed to reduce the presence of unaesthetic scars in preauricular and facial regions, with surgical results undoubtedly comparable to the traditional surgical techniques much more aggressive. Our technique could be a valid, alternative, and safe approach to treat this rare and complex kind of oncological disease.

    The purpose of this study was to clarify the spatial relationship of temporomandibular joint and to an aid in the diagnosis of temporomandibular disorder. For this study, three-dimensional images of normal temporomandibular joint were reconstructed by computer image analysis system and three-dimensional reconstructive program integrated in computed tomography. The obtained results were as follows : 1. Two-dimensional computed tomograms had the better resolution than three dimensional computed tomograms in the evaluation of bone structure and the disk of TMJ. 2. Direct sagittal computed tomograms and coronal computed tomograms had the better resolution in the evaluation of the disk of TMJ. 3. The positional relationship of the disk could be visualized, but the configuration of the disk could not be clearly visualized on three-dimensional reconstructive CT images. 4. Three-dimensional reconstructive CT images had the smoother margin than three-dimensional images reconstructed by computer image analysis system, but the images of the latter had the better perspective. 5. Three-dimensional reconstructive images had the better spatial relationship of the TMJ articulation, and the joint space were more clearly visualized on dissection images.

    Hematic cyst refers to accumulation of blood or blood breakdown products in a non epithelium-lined fibrous tissue capsule. Hepatic cyst is a term often used for deeply placed, incompletely resorbed hematoma hemorrhagic cyst, which may remain unchanged and unidentified for long periods of time. Trauma is the major causative factor, although it is often vague or totally uncalled by the patient. Chronic hematic cysts are uncommon lesions those can present diagnostic challenge. In this article we report a first case of a chronic hematic cyst of the temporomandibular joint TMJ. (author)

    Patients with temporo-mandibular joint (TMJ) dysfunction need complex treatment that includes prosthetic treatment in intrajoint relation stabilization. In cases of TMJ pathology it is necessary to examine patients and make axiography, function analysis, MPI-analysis, magnetic resonance tomography and zonography of TMJ, electromyography of the masticatory muscles. The authors examined 47 patients with TMJ dysfunction, 43 of them had occlusion pathology. We managed to eliminate the dysfunction symptoms and to receive stable result of the treatment in all the patients.

    Crepitus is an important sign for diagnosis of arthrosis of the temporomandibular joint (TMJ). The presence of crepitus can be evaluated by the listening test previously proposed by our group. However, TMJ can be diagnosed by MR imaging showing the disc position and related findings including bony changes and joint effusion. This study investigated the relationship between the presence of crepitus and pathology of the joint. Fourteen joints with crepitus diagnosed by the listening test were examined in this study. TMJ was categorized into four types based on findings on double spin echo MR images. The results were as follows: Of fourteen joints with crepitus, five (36%) were showed as normal superior disc position. The remaining 9 joints (64%) were diagnosed with disc displacement, of which, 6 showed reduction, one was without reduction and 2 without reduction were associated with arthrosis. Statistical analysis using the data obtained here and other data showed that the joints with crepitus tended to show disk displacement. There was no significant difference between the degree of certainty about the presence of the crepitus and the distribution of joint pathology. Joint effusion was observed only in the joints with displacement. These results indicated that TMJ with crepitus is associated with varied joint pathology. (author)

    To evaluate the effect of total joint replacement in treatment of temporomandibular joint(TMJ) osteoarthropathy with stock prostheses. Six female patients involving 10 joints (2 unilateral and 4 bilateral), with an average age of 59 years old, were involved in this study. Three patients (5 joints) were diagnosed as internal derangement in V stage depending on MRI, 3D-CT findings and clinical characteristics. The other 3 patients (5 joints) had histories of failed temporomandibular joint operation using costochondral graft or temporalis fascial flap. The maximal mouth opening was 1.9 cm on average (range, 1.0 to 2.9cm). All the joints were replaced with Biomet standard prosthesis under general anesthesia. The follow-up period was from 7 to 49 months (average, 17.5 months). All the operations were successfully performed. Heterotopic ossification happened in a bilateral case 1 year postoperatively. One patient with bilateral joint disease complained of severe uncomfortable feeling in the region of the ears and the temples, although there was no significant positive signs according to an ENT examination. Pain relief of the joint and mouth opening improvement were significant in 4 patients. No failure was noted secondary to infection or loosening of the prostheses. The occlusal relationship kept stable postoperatively in all cases. Total TMJ joint replacement with standard prosthesis is a good choice for TMJ reconstruction. It can significantly reduce joint pain and the mouth opening limitation resulted from osteoarthritis. Long-term result remains to be evaluated based on a long-term follow-up.

    Full Text Available Abstract Background Virtually all the articles in literature addressed only a specific type of dislocation. The aim of this review was to project a comprehensive understanding of the pathologic processes and management of all types of dislodgement of the head of the mandibular condyle from its normal position in the glenoid fossa. In addition, a new classification of temporomandibular joint dislocation was also proposed. Method and materials A thorough computer literature search was done using the Medline, Cochrane library and Embase database. Key words like temporo-mandibular joint dislocation were used for the search. Additional manual search was done by going through published home-based and foreign articles. Case reports/series, and original articles that documented the type of dislocation, number of cases treated in the series and original articles. Treatment done and outcome of treatment were included in the study. Result A total of 128 articles were reviewed out which 79 were found relevant. Of these, 26 were case reports, 17 were case series and 36 were original articles. 79 cases were acute dislocations, 35 cases were chronic protracted TMJ dislocations and 311 cases were chronic recurrent TMJ dislocations. Etiology was predominantly trauma in 60% of cases and other causes contributed about 40%. Of all the cases reviewed, only 4 were unilateral dislocation. Various treatment modalities are outlined in this report as indicated for each type of dislocation. Conclusion The more complex and invasive method of treatment may not necessarily offer the best option and outcome of treatment, therefore conservative approaches should be exhausted and utilized appropriately before adopting the more invasive surgical techniques.

    2007-01-01

    Synovial Chondromatosis (SC) is a disease whose etiology is unknown, can be defined as a benign synovial process characterized by the formation of metaplastic cartilaginous nodes inside connective tissue of articular surfaces, is considered an active metaplastic phenomenon better than a neoplastic process; it presents a greater preference to affect women who constitute almost 70% of reported cases, the age range is wide and oscillates between 18-75 years (average 44.6 years). Between the main clinical findings are: pain, crackle, volume augmentation and a limited buccal opening. SC is an unusual state and the reports in the English literature are no more than 75 cases, only 66 of those where histologically verified, most of those were affecting great joints like hip, knee and shoulder, but if SC is not frequent in this sites, is even more infrequent on temporomandibular joint. The aim of this paper is to report a clinical case and at the same time to realize a brief review of the literature.

We are reporting two cases of TMJ dislocation resulted from acute severe intoxication with pure propranolol (PPL for the first time. Bilateral TMJ dislocation happened in two patients who were admitted to intensive care unit with diagnosis of severe acute PPL toxicity. Clinical diagnosis of TMJ dislocation was obtained by physical examination. Successful reduction was performed for both patients without subsequent recurrence in two weeks following hospital discharge. Both of our subjects had no previous history of lower jaw dislocation. There was not any risk factor for dislocation such as convulsion during admission period, recent face trauma, or oral manipulation by the medical team. This study showed that TMJ dislocation may occur after severe acute PPL toxicity probably due to spastic contraction of the lateral pterygoid muscle. This is against previously mentioned hypothesis that stated masseteric muscles contraction as the main cause of a bilateral dislocated TMJ.Keywords: propranolol, toxicity, temporomandibular joint dislocation

    Recent years have shown an increase in the number of patients reporting for treatment of pain due to musculoskeletal joint, associated with temporomandibular joint dysfunction. Therefore, studies were undertaken, aimed at analyzing the symptoms of the dysfunction, because of which patients come to the prosthetic treatment. Aim of the thesis: The aim of the study was a retrospective analysis of symptoms of temporomandibular joint dysfunction reported by patients diagnosed with this problem. The research material was a retrospective medical records of 120 patients, aged 19 to 45 years who have taken prosthetic treatment due to temporomandibular joint dysfunction in the Consulting Room in Prosthetics Department in Kraków, from June 2015 to December 2016. During the test patients, in addition to interviewing a physician, completed a personal survey in their own study. The material has been divided into I group of patients who reported pain form of dysfunction and II group, who had no symptoms of pain within the stomatognatic system. The analysis covered type of symptoms, the share of local factors (para-functions) and systemic, as well as the time a er which the patients reported for the treatment of functional disorders since the appearance of the first symptoms. Analysis of the research material showed that the main reason for reporting patients was pain in one or both temporal joints of significant intensity (5 to 8 in VAS scale,) accompanied by acoustic symptoms. A large group of questioners reported problems with the range of jaw movement and head and face pain, as well as subjective symptoms from the auditory, sight, neck, neck and shoulder areas.

    Full Text Available The aim of this study was to compare treatment outcomes following intramuscular injection of botulinum neurotoxin (BoNT in patients with recurrent temporomandibular joint dislocation, with and without muscle hyperactivity due to neurological diseases. Thirty-two patients (19 women and 13 men, mean age: 62.3 years with recurrent temporomandibular joint dislocation were divided into two groups: neurogenic (8 women and 12 men and habitual (11 women and 1 man. The neurogenic group included patients having neurological disorders, such as Parkinson’s disease or oromandibular dystonia, that are accompanied by muscle hyperactivity. BoNT was administered via intraoral injection to the inferior head of the lateral pterygoid muscle. In total, BoNT injection was administered 102 times (mean 3.2 times/patient. The mean follow-up duration was 29.5 months. The neurogenic group was significantly (p < 0.001 younger (47.3 years than the habitual group (84.8 years and required significantly (p < 0.01 more injections (4.1 versus 1.7 times to achieve a positive outcome. No significant immediate or delayed complications occurred. Thus, intramuscular injection of BoNT into the lateral pterygoid muscle is an effective and safe treatment for habitual temporomandibular joint dislocation. More injections are required in cases of neurogenic temporomandibular joint dislocation than in those of habitual dislocation without muscle hyperactivity.

    A finite element model of the temporomandibular joint (TMJ) and the human mandible was fabricated to study the effect of abnormal loading, such as awake and asleep bruxism, on the articular disc. A quasilinear viscoelastic model was used to simulate the behaviour of the disc. The viscoelastic nature of this tissue is shown to be an important factor when sustained (awake bruxism) or cyclic loading (sleep bruxism) is simulated. From the comparison of the two types of bruxism, it was seen that s...

  8. Management of temporomandibular joint ankylosis with combination of gap arthroplasty surgery and physiotherapy

    Directory of Open Access Journals (Sweden)

    2017-08-01

    Full Text Available Background. Temporomandibular joint (TMJ ankylosis is a union of the articular surface of the temporal bone to the disc-condyle complex that restricts mandibular movements due to either a fibrous or bony union between the head of the condyle and the glenoid fossa. Common etiological factors are trauma, infection, and pathology in the joint or systemic diseases. The diagnosis of TMJ ankylosis is established through physical and clinical evaluation, and imaging examination. Currently, the surgical techniques used to treat TMJ ankylosis are gap arthroplasty, interpositional arthroplasty, joint reconstruction, and distraction osteogenesis. Purpose. To provide overview about management of temporomandibular joint ankylosis with gap arthroplasty combined with physiotherapy post surgery. Case. A 12-year-old female patient came to Department of Oral and Maxillofacial Surgery with complaint of opening mouth restriction, which occured since one year prior to admission. After complete physical and radiographic examination, patient then was diagnosed with TMJ ankylosis due to neglected odontogenic infection. The treatment was performed with gap arthroplasty under general anesthesia. Patient then underwent physiotherapy after the surgery, including application of heat on the affected region and exercises to open and close mouth. Discussion. Ankylosis of TMJ is an uncommon case that results in chronic and severe limited mouth opening. The critical factor of successful treatment of TMJ ankylosis is early detection, correct surgery approach, implementation of an intensive physiotherapy program, and a good post-operative conduct. Therefore on this patient, gap arthroplasty was the chosen surgery approach followed by intensive physiotherapy. Conclusion.Management goal in TMJ ankylosis is  to increase the patient’s mandibular function, correct associated facial deformity, decrease pain, and prevent reankylosis. Careful surgical technique and subsequent atten

    Using an autoradiographic method, the temporomandibular joint (TMJ) complex of five aged female baboons was studied for the presence of receptors for estradiol-17 beta. The study was performed in an effort to learn more of the pathophysiology of this joint and in an attempt to provide a scientific basis to explain the reported preponderance of women who seek and undergo treatment for signs and symptoms referable to the TMJ. This experiment revealed that the TMJ complex contains numerous cells with receptors for estrogen, particularly the articular surface of the condyle, articular disk, and capsule. Muscles of mastication contained relatively fewer receptors. As a result, one may postulate a role for the sex steroid hormones in the maintenance, repair, and/or pathogenesis of the TMJ. Additional studies are necessary to fully determine the significance of hormone receptors in this site and any correlation between diseases of the TMJ and the endocrine status of affected patients.

    This is a histological study of the human temporo-mandibular joint and its surrounding muscles. Using a microscopic study of serial sections from anatomical specimens from six subjects, the detailed anatomy of the joint is presented with particular regard to the histology. This study has allowed, in particular, the description of the ligaments and capsule as well as the insertions of the masticatory muscles (temporalis, masseter, lateral pterygoid) on this joint. These observations are then compared with the anatomical and histological data already reported on this subject. This study shows that the bulk of the muscular fibres of the lateral pterygoid passes under the foot of the disc is attached over the whole height of the condylar, unite and extend as far as the medial pole of the joint under the insertion of the articular disc. An insertion of the temporo-masseter musculo-tendinous complex on the anterior and lateral capsulo-discal structures was observed. The lateral pterygoid is composed of a succession of tendinous and fleshy fibres. This study confirms the thickening of the lateral capsule that corresponds to a lateral collateral ligament, and the absence of a medial collateral ligament. Medial stability is conferred by the lateral ligament of the contralateral joint.

  14. Long-Term Symptoms Onset and Heterotopic Bone Formation around a Total Temporomandibular Joint Prosthesis: a Case Report

    Luca Guarda-Nardini

    2014-04-01

    Full Text Available Background: The literature on total alloplastic temporomandibular joint (TMJ reconstructions is encouraging, and studies on total alloplastic TMJ replacements outcomes showed acceptable improvements in terms of both pain levels and jaw function. Nevertheless, some adverse events, such as heterotopic bone formation around the implanted prosthesis, may occur. In consideration of that, the present manuscript describes a case of heterotopic bone formation around a total temporomandibular joint prosthesis, which occurred several years after the implant. Methods: The present manuscript describes a case of heterotopic bone formation around a total TMJ prosthesis, which occurred several years after the implant in patients, who previously underwent multiple failed TMJ surgeries. Results: Ten years after the surgical TMJ replacement to solve an ankylotic bone block, the patient came to our attention again referring a progressive limitation in mouth opening. A computerized tomography showed evidence of marked heterotopic bone formation in the medial aspects of the joint, where a new-born ankylotic block occupied most part of the gap created by resecting the coronoid process at the time of the TMJ prosthesis insertion. Conclusions: Despite this adverse event has been sometimes described in the literature, this is the first case in which its occurrence happened several years after the temporomandibular joint replacement. It can be suggested that an accurate assessment of pre-operative risk factors for re-ankylosis (e.g., patients with multiple failed temporomandibular joint surgeries and within-intervention prevention (e.g., strategies to keep the bone interfaces around the implant separated should be better standardized and define in future studies.

    This systematic review provides an overview of the historical evolution of the prosthetic temporomandibular joint and addresses the challenges and complications faced by engineers and surgeons, in an effort to shed light on why only a few systems remain available. A better understanding of the history of temporomandibular joint prostheses might also provide insights into the origin of the negative public opinion of the prosthesis, which is based on outdated information. A computerized search using the PubMed Central, ScienceDirect, Wiley Online, Ovid, and Cochrane Library databases was performed following the PRISMA guidelines. Out of 7122 articles identified, 41 met the inclusion criteria for this systematic review. Although several historical reviews have been published previously, none has covered such an extensive time period or has described all designs. Furthermore, besides providing a historical overview, this review discusses the rationale behind the evolution in design and biomaterials, which have largely contributed to the outcomes of the prosthetic systems.

  17. Reevaluating Antidepressant Selection in Patients With Bruxism and Temporomandibular Joint Disorder.

    Science.gov (United States)

    Rajan, Royce; Sun, Ye-Ming

    2017-05-01

    Temporomandibular joint disorder (TMD) is a broad pain disorder that refers to several conditions affecting the temporomandibular joint of the jaw and the muscles of mastication. As with most pain disorders, a high prevalence of depression and anxiety is associated with TMD. Research has shown that selective serotonin reuptake inhibitors (SSRIs), the first-line drug therapy for major depressive disorder, may not be suitable for TMD patients because SSRIs can induce teeth-grinding, otherwise known as bruxism. This is problematic because bruxism is believed to further exacerbate TMD. Therefore, the purpose of this literature review is to better understand the mechanism of SSRI-induced bruxism, as well as discuss alternative antidepressant options for treating depression and anxiety in patients with bruxism and TMD. Alternative classes of antidepressants reviewed include serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants, atypical antidepressants, and monoamine oxidase inhibitors. Findings indicate that dopamine agonists and buspirone are currently the most effective medications to treat the side effects of SSRI-induced bruxism, but results regarding the effectiveness of specific antidepressants that avoid bruxism altogether remain inconclusive.

    A new technique of manufacturing dual-colour stereolithographic models of hard and soft tissues of the temporomandibular joint (TMJ) is presented. Sagittal T1/PD weighted magnetic resonance (MR) images of joints with and without disc displacement were obtained in the closed and open mouth positions. Individual interactive contour identification of bony structures and the articular disc followed by binary interpolation provided the data for the generation of acrylic TMJ models. Three dimensional in vivo visualization of the articular disc in relation to bony structures in the closed and open mouth positions allows a new perception of normal and pathological TMJ anatomy.

    The present study was designed to verify the correlation between tinnitus and temporomandibular joint dysfunction.86 consecutive patients were enrolled in the study, all affected by subjective tinnitus without hearing impairment, from both genders, age between 18 and 60 years old. The final number of patients included in the study was 55. All patients received a temporo-mandibular joint examination. All the patients were asked to rate the severity of their symptoms before and after treatment using a VAS scale and the Tinnitus Handicap Inventory (THI) and they followed a standardized protocol for the investigation of tinnitus. All the subjects were monitored by the same researcher and they underwent the same splint treatment. The comparison between pre- and posttreatment phase scores showed in patients with predisposition of TMD and with TMD a statistically significant decrease of THI and VAS values. The characteristics of tinnitus and the degree of response to treatment confirmed the relationship between tinnitus and TMD. The authors believe that, when the most common causes of tinnitus, such as otologic disorders and neurological diseases are excluded, it is correct to evaluate the functionality of the temporo-mandibular joint and eventually treat its pathology to obtain tinnitus improvement or even resolution.

    Full Text Available BackgroundThis study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty.MethodsA prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpositional arthroplasty in 13 cases. The patients were followed for three years. Collected data were tabulated and subjected to Fisher's exact test, chi-square test and probability estimation.ResultsA significant increase in interincisal distance of 32 mm was seen in 12 (92.31% patients in the T-plate interposition group, in 2 (25% cases of the temporalis muscle flap interposition group, and in 1 case (14.28% of the condylectomy group at 12, 24, and 36 months. Re-ankylosis was observed in 1 case (9.69% of the T-plate interposition group, while as it was observed in 4 (50% cases in the temporalis muscle flap interposition group and 4 (57.14% cases in the condylectomy group, and these differences were statistically significant.ConclusionsOur clinical experience with the use of the T-plate over the past 5 years has been encouraging, and our physiotherapy technique is quite simple. Even illiterate parents can assess it easily. Hence, we recommend this easy technique that does not damage the temporalis muscle for the management of temporomandibular joint ankylosis.

    Temporomandibular joint and dental occlusion are joined for better and worse. TMJ has its own weaknesses, sometimes indicated by bad functional habits and occlusal disorders. Occlusal analysis needs to be addressed simply and clearly. The term "malocclusion" is not reliable to build epidemiological studies, etiologic mechanisms or therapeutic advice on this "diagnosis". Understanding the impact of pathogenic malocclusion is not just about occlusal relationships that are more or less defective, it requires to locate them within the skeletal framework, the articular and behavioural context of the patient, and above all to assess their impact on the functions of the masticatory system. The TMJ-occlusion couple is often symbiotic, developing together in relation to its environment, compensating for its own shortcomings. However, a third partner may alter this relationship, such as bruxism, or more generally oral parafunctions, trauma or an interventionist practitioner. Copyright © 2016 Elsevier Masson SAS.

    The purpose of this study was to investigate the distribution and frequency of temporomandibular joint (TMJ) effusion in magnetic resonance (MR) images of patients with disc displacements. On T2 weighted MR images of 148 TMJs taken from 74 patients presenting with TMJ pain and dysfunction, we assessed the cases showing TMJ effusion, defined as an amount of fluid that exceeded the maximum amount seen in a control group of asymptomatic volunteers. The amount of TMJ fluid was graded as: I (none or minimal), II (moderate), III (marked), and IV (extensive), according to a standard set by a reference. Disc displacement categories were also recorded. Of the 148 TMJs examined in this study, 52 joints (35.1%) presented with joint effusion, 24 (16.2%) showing bilateral joint effusion. 38 joints showed upper joint space effusion, and 3 showed lower joint space effusion, and 11 showed both upper and lower joint space effusion. 96 joints (64.9%) had grade I joint fluid, 27 (18.2%) grade II, 15 (10.1%) grade III, and 10 (6.8%) grade IV. 80.0% of the joints presenting with grade IV effusion showed disc displacement without reduction. Joint effusion was found not only in upper, but also in lower joint spaces. The higher the effusion grade, the greater the frequency of disc displacement without reduction.

    13 patients who sustained mandibular trauma were investigated with radiographs and scintiscans. The scintiscans showed abnormal uptake of radiopharmaceutical in the temporomandibular joint (TMJ). In patients with a long history of traumatic arthrosis, there was more positive correlation between the scintiscans, and clinical symptoms and histology than between radiographs, and symptoms and histology. In patients with mandibular body fractures and no TMJ symptoms, the scans showed abnormal uptake in the TMJ in 7/8 joints, in the absence of radiographic abnormality. The significance of the abnormal uptake and the value of scintigraphy is discussed.

    To examine the possible relationship between condylar position and disk displacement in the temporomandibular joint. 79 temporomandibular joints in 40 patients having temporomandibular disorders were classified into three categories: no disk displacement (NDD), disk displacement with reduction (DDWR), and disk displacement without reduction (DDWOR). Disk positions were assessed from clinical and MRI findings. The relationship between the three categories and condylar positions was evaluated using lateral individualized corrected tomography. Clinical findings regarding the relationship between condyle and disk positions having anterior, centric, and posterior positions were 27%, 27%, and 46%, respectively, in NDD, 43%, 17%, and 40%, respectively, in DDWR, and 44%, 22%, and 34%, respectively, in DDWOR. There were no significant differences in condylar positions between each of the groups (P>0.05). In the relationship between condyle and disk positions with MRI findings, anterior, centric, and posterior positions were 38%, 38%, and 24%, respectively, in NDD, 29%, 21%, and 50%, respectively, in DDWR, and 44%, 9%, and 47% respectively, in DDWOR. There were significant differences in the condylar positions when MRI was utilized (P<0.05). There was a significant correlation between the condyle and disk positions with MRI findings on lateral individualized corrected tomography.

    Osteohistometric studies were performed in 15 female and 15 male cadavers aged 18-25. Condyloid process and right and left acetabulum of the temporo-mandibular joint have been studied. Density has been investigated using monitor screen linked with microscope (magnification 80x). Density in the spongy part of the condyloid process was 26.67-26.77%; in the subchondrial layer--72.13-72.72%, and in the acetabular wall 75.03-75.91%. Microscopic structure of the bones of the temporo-mandibular joint revealed no differences when compared with images of compact and cancellous bone shown in the histology textbooks. Sex and the side of the body had no influence on microscopic image and proportional bone density. Isles of chondrocytes in the trabeculae of the spongy structure of the condyloid process were found in 4 cases and isles of the condensed bone resembling the compact pattern in 7 cases.

    Recurrent pains of the temporomandibular joint represent a frequent symptom with numerous different causes. CT and MRI can reliably show the cause of these disorders and therefore have substituted conventional X-ray imaging. Modern multi-slice-CT (MSCT) allows for examination of the skull base including the mandible in a very short time with thinnest slice collimation (0.75 mm). With 2D- and 3D- reformations reconstructed out of this volume data set in parasagittal, coronal or any other arbitrary slice orientation excellent imaging of fractures and bony changes of arthrosis as well as benign and malignant tumors of the temporomandibular joint can be performed. MRI offers very good soft tissue contrast in order to visualize the intra-articular disc, the ligaments and muscles, as well the possibility to acquire cross sectional images in any user-defined orientation. MRI is the method of choice to diagnose 'internal derangement', particularly displacement of the intra-articular disc and inflammatory disease of the temporomandibular joint. The present paper will provide diagnostic strategies for the use of MSCT or MRI imaging concerning the different causes of disorders to the temporomandibular joint. (orig.)

    The purpose of this study was to determine the diagnostic value of high-resolution ultrasonography (US) in temporomandibular joint (TMJ) disc displacements. A number of 74 patients (148 TMJs) with signs and symptoms of TMJ disorders, according to the Research Diagnostic Criteria for Temporomandibular Disorders, were included in this study. All patients received US and magnetic resonance imaging (MRI) of both TMJs 1 to 5 days after the clinical examination. MRI examinations were performed using 1.5 T MRI equipment (Siemens Avanto, Siemens, Erlangen). Ultrasonographic examination was performed on a Hitachi EUB 8500 (Hitachi Medical Corp., Tokyo, Japan) scanner with L 54 M6.5-13 MHz linear transducer. MRI depicted 68 (45.95%) normal joints, 47 (31.76%) with disc displacement with reduction, 33 (22.3%) with disc displacement without reduction and 34 (22.97%) with degenerative changes. US detected 78 (52.7%) normal joints, 37 (25%) with disc displacement with reduction, 33 (22.3%) with disc displacement without reduction and 21 (14.19%) with degenerative changes. Compared to MRI, US showed a sensitivity of 93.1%, specificity of 87.88%, accuracy of 90.32%, a positive predictive value of 87.1% and a negative predictive value of 93.55% for overall diagnosis of disc displacement. The Youden index was 0.81. Based on our results, high-resolution ultrasonography showed high sensitivity, specificity and accuracy in the diagnosis of TMJ disc displacement. It could be a valuable imaging technique in assessing TMJ disc position. The diagnostic value of high-resolution ultrasonography depends strictly on the examiner's skills and on the equipment used.

    Full Text Available Background: Temporomandibular joint (TMJ ankylosis or hypomobility involves fusion of the mandibular condyle to the base of the skull. It is a major clinical problem that affects many patients suffering from facial trauma, infection, or systemic disease. The treatment of TMJ ankylosis poses a significant challenge because of technical difficulties and a high incidence of recurrence. Case Report: This report describes a case of a 4-year-old boy with inability to open mouth, diagnosed with unilateral right bony TMJ ankylosis. The surgical approach consisted of gap arthroplasty followed by vigorous physiotherapy. Conclusion: A detailed history, clinical and functional examination, radiographic examination facilitating correct diagnosis followed by immediate surgical intervention, and physiotherapy can help us to restore physical, psychological, and emotional health of the child patient.

    This paper determines the prevalence of internal derangement (ID) of the temporomandibular joint (TM) in a population of children prior to orthodontic therapy. Thirty-two children, aged 7-15 years, with a variety of orthodontic disorders underwent both MR imaging and physical examination to assess ID of the TMJ. With MR imaging, the disks were graded as normal, borderline anterior displaced, or anterior displaced. Fifty-nine TMJs in 32 patients were successfully imaged. Five TMJ MR examinations could not be interpreted because of patient motion. Fifty seven of the 59 joints (97%) were normal. One disk (1.7%) was anterior displaced, and one (1.7%) was considered borderline

    Full Text Available Complicated tooth extractions may lead to various post-extraction complications, including Temporomandibular Joint Disorders (TMD. Despite of the rare incidence, a delayed treatment of the TMD will cause more problems in the future as well as increased morbidity rate. The purpose of the current study was to elaborate the symptoms as well as the management of TMD as a post tooth extraction complication. The types of TMD as a post tooth extraction complication includes dislocated condyle, osteoarthritis, fracture condyle and disc displacement. These type of complications may resulted from an extensive opening of the mouth as well as an over pressure on the mandible during tooth extraction. In relation to this, some of the TMD symptoms that might cause a certain level of interference for patients may include pain, limited mouth opening and joint sounds, with pain and limited mouth opening as the initial symptoms. The first measure of the pain management would be warm light compress around the TMJ followed by a soft diet for food intake. A definitive treatment should then be based on the diagnosis of the TMD. It is concluded that TMD may occur as a complication of a tooth extraction that initiated by pain and limited mouth opening. Immediate treatment would be pain relieve and load reduction of the Temporomandibular Joint by employing soft diet and mandibular movement restriction.

    Background Petrotympanic fissure (PTF) is a fissure in the temporal bone that runs from the temporomandibular joint (TMJ) to the tympanic cavity (TC). In PTF, the discomallear ligament (DML) connects the malleus in the tympanic cavity and the articular disc and capsule of the temporomandibular joint. PTF with the DML is a possible cause of aural symptoms related to temporomandibular joint dysfunction (TMD). Purpose To investigate the prevalence of different types of PTF in TMD using dental volumetric tomography (DVT) and determine whether PTF type correlates with age. Material and Methods DVT scans in the sagittal planes of PTFs of 134 patients with TMD were examined for the types of PTF present. Three main PTF types were described: wide, tunnel-shaped structure (type 1); tunnel-shaped structure that is wide open in the PTF entrance to the mandibular fossa and gradually thins out in the tympanic cavity (type 2), tunnel-shaped structure that is wide open in the entrance of the mandibular fossa, with a middle region with a flat-shaped tunnel structure and a narrow exit in the tympanic cavity (type 3). Results In DVT scans, PTF types 1, 2 and 3 were seen in 67.2%, 1.5%, and 31.3% of cases, respectively. We found no significant relationship between age or gender and PTF type. Conclusion The low percentage of type 2 PTF and high percentage of type 1 PTF must be taken into consideration during pre-surgical planning related to TMD. However, future well-designed clinical studies involving larger numbers of subjects will be necessary to confirm the findings of this study

    2014-06-01

    A finite element model of the temporomandibular joint (TMJ) and the human mandible was fabricated to study the effect of abnormal loading, such as awake and asleep bruxism, on the articular disc. A quasilinear viscoelastic model was used to simulate the behaviour of the disc. The viscoelastic nature of this tissue is shown to be an important factor when sustained (awake bruxism) or cyclic loading (sleep bruxism) is simulated. From the comparison of the two types of bruxism, it was seen that sustained clenching is the most detrimental activity for the TMJ disc, producing an overload that could lead to severe damage of this tissue.

    Temporo-mandibular joint ankylosis is a common cause of acquired deformity in children. Surgical correction of the ankylosis only leaves the patient with an uncorrected mandibular deformity. This study was to evaluate the use of distraction osteogenesis for simultaneous correction of the mandibular deformity. This study was done on six children with temporo-mandibular joint ankylosis and mandibular deformity. Uniaxial double pin distractors with Schanz pins were used in this study. The patients underwent simultaneous gap arthroplasty and mandibular osteotomy (retromolar) with distractor insertion. Distraction was started on the fifth post-operative day. The patients were put on dynamic temporo-mandibular joint exercises on the first post-operative day. All patients had a satisfactory mouth opening on follow-up. Satisfactory cosmetic correction of the mandibular deformity was also achieved in all these patients. Some degree of malocclusion resulted from treatment due to which the patients were placed on orthodontic treatment. Distraction osteogenesis can be used simultaneously with gap arthroplasty in patients with temporo-mandibular ankylosis, for the correction of the mandibular deformity.

    Temporo-mandibular joint (TMJ) dislocation is an unusual complication of transoesophageal echocardiography (TEE). We report a rare case of bilateral TMJ dislocation in an 84-year-old man prior to DC cardioversion (DCCV) for atrial flutter. Shortly after TEE and DCCV, the patient complained of bilateral facial pain. An orthopantomogram revealed bilateral TMJ dislocation. A closed reduction was performed by maxillo-facial surgeons under intravenous anaesthesia. Although very uncommon, the physician should be aware of the complication and its management.

    Case report: A 59-year-old male presented to our department with bony ankylosis of his temporomandibular joints bilaterally as a result of previous osteomyelitis. He underwent bilateral temperomandibular joint replacements in a two-stage procedure. Six weeks post discharge he presented to the emergency department in haemorrhagic shock, having lost significant blood volume from a pulsatile lesion over his right mandible. Computed tomography angiography revealed a pseudoaneurysm of the right facial artery. He proceeded to emergent embolisation with resolution of the pseudoaneurysm.

    Temporomandibular (TM) joint pain results from many etiologic factors. The aim of this study was to evaluate the utility of Bone SPECT in patients with TM joint pain. The subjects were 34 patients with TM joint pain. All patients underwent plain radiography, planar bone scan, and Bone SPECT. The intensity of radioisotope uptake at TM joint was graded into three; no increased uptake above the background activity as grade 0, uptake similar to occipital bone as grade I, and uptake similar to maxillary sinus as grade II. Clinical findings and therapeutic methods were reviewed. Twenty-seven patients (80%) out of 34 patients with TM joint pain had increased uptake in bone SPECT. Twenty-one (78%) out of 27 patients had increased uptake in the mandibular condyle and remaining six patients (22%) had uptake in the mandibular and maxillary arch, which proved to be dental problem. Seven patients (21%) out of 34 were grade as 0, four (12%) were grade I, 23 (68%) were grade. II. Four patients with grade I had clicking sound and symptoms which were subsided with medication in all cases. Among 23 patients with grade II, 7 patients had clicking sound and 14 patients underwent medication and decompression therapy. With Planar bone scan, 11 cases (32%) had increased uptake in TM joint area. Plain radiography revealed narrowing, distension, erosion and limitation of TM joint in 16 cases (47%). Bone SPECT can be valuable for screening and managing the patients with TM joint pain. Patients with grade II needed intensive treatment such as joint aspiration. However degree of the radioisotope uptake did not well correlated with clinical symptoms

    Objective: the present study was aimed at identifying temporomandibular joint inflammatory processes employing technetium-99m hexamethyl propylene amine oxime (99mTc-HMPAO)-labeled autonomous leukocytes. Materials and methods: we have utilized an experimental model of arthritis induction in ten adult male New Zealand rabbits by means of ovalbumin intra-articular injection into each left temporomandibular joint. For control purposes, saline solution was injected. After leukocytes radiolabeling with 99mTc-HMPAO and injection into rabbits, scintigraphic images were obtained. Results: a higher 99mTc-HMPAO-leukocytes uptake was observed in left temporomandibular joint in comparison with the contralateral joint. Wilcoxon non-parametric test was applied for statistical analysis. There was a statistically significant difference between counts of radioactivity per minute in the inflamed joint and the contralateral one (p = 0.0073). Conclusion: the method employing 99mTc-HMPAO-labelled autologous leukocytes allows an early and accurate detection of inflammatory processes, contributing to the adoption of a therapeutic conduct for patients before structural alterations have occurred.

    Pathological changes in soft tissues surrounding the fracture site as well as in the structural elements of temporo-mandibular joint always occured in condylar process fracture with shift at cervical mandibular jaw level. Other changes were also seen in the joint on the opposite normal side. Modelling of condylar process fracture at mandibular cervical level by means of three-dimensional computer model of temporo-mandibular joint contributed to proper understanding of this pathology emergence as well as to prediction and elimination of disorders arising in adjacent to the fracture site tissues.

    To analyze the possible association between magnetic resonance imaging signal intensity of temporomandibular joint disk and posterior attachment, and the type and extent of disk displacement, disk donfiguration, effusion and clinical signs in patients with internal derangement. Magnetic resonance images of the 132 temporomandibular joints of 66 patients with temporomandibular joint displacement were analyzed. The clinical findings were obtained by retrospective review of the patients' records. The type and extent of disk displacement, disk configuration and effusion were evaluated on the proton density MR images. The signal intensity from the anterior band, posterior band and posterior attachment were measured on MR images. The associations between the type and extent of disk displacement, disk configuration, effusion and clinical signs and the MR signal intensity of disk and posterior attachment were statistically analyzed by student's t-test. Of 132 joints, 87 (65.9%) showed anterior disk displacement with reduction (ADR) and 45 (34.1%) showed anterior disk displacement without reduction (ADnR). This signals from posterior attachments were lower in joints with ADnR than those of ADR (p<0.05). The results showed statistically significant (p<0.05) association between the type and extent of disk displacement and disk configuration, and decreased signal intensity of posterior attachment. There were no statistical associations between pain, noise and limited mouth opening, and signal intensity of disk and posterior attachment. The average signal from posterior attachment was lower in joints with ADnR than that of ADR. The type and extent of disk displacement and disk configuration appeared to be correlated with the signal intensity from posterior attachment

    Robert Pellecchia, DDS

    2015-12-01

    Full Text Available Tophaceous pseudogout, a variant of calcium pyrophosphate dihydrate deposition, is a relatively rare juxta-articular disease. It is a metabolic condition, in which patients develop pseudo-tumoral calcifications associated with peri-articular structures secondary to calcium pyrophosphate deposition into joints with fibrocartilage rather than hyaline cartilage. These lesions are reported in the knee, wrist, pubis, shoulder, and temporomandibular joint (TMJ and induce a histocytic foreign body giant cell reaction. We report a case of tophaceous pseudogout affecting the left TMJ with destruction of the condyle and glenoid and middle cranial fossa that was reconstructed with a TMJ Concepts (Ventura, CA custom-fitted prosthesis in a 2-staged surgical approach using a silicone spacer. The surgical management using a patient-specific TMJ is a viable option when the fossa or condylar component has been compromised due to breakdown of bone secondary to a pathologic process. Our case describes and identifies the lesion and its rare occurrence in the region of the temporomandibular region. The successful management of tophaceous pseudogout of the TMJ must include a thorough patient workup including the involvement of other joints as well as the modification of bone of the glenoid fossa and condylar relationship of the TMJ.

    Full Text Available Background: Fractures of the mandibular condyle may lead to complications such as disturbance of occlusal function, internal derangement of the joint, ankylosis and mandibular growth disturbance. When treating young patients with the history of mandible trauma, ankylosis of the temporomandibular joint and mandibular growth disturbance are two most important complications of condyle fracture that should be considered. Purpose: This case report attempts to emphasize the long term complication of neglected condylar fracture in children i.e. ankylosis of the temporomandibular joint and subsequently lead to mandibular growth disturbance. Case: A case of right temporo-mandibular joint ankylosis and mandibular growth disturbance in a 28 years old male patient is presented. He had a history of trauma to the mandible after a traffic accident when he was 8 years old. Since then, he experienced difficulty in mouth opening which eventually developed into severe trismus. Case management: The case was treated surgically with gap and interpositional arthroplasty using Mersilen mesh™. Conclusion: Mandibular fractures involving temporomandibular joint in young children should be examined thoroughly and treated adequately in order to prevent ankylosis of the TMJ and the subsequent mandibular growth disturbance.Latar belakang: Fraktur pada kondilus mandibula dapat menyebabkan beberapa komplikasi berupa: gangguan oklusi, internal derangement sendi, ankilosis serta gangguan pertumbuhan mandibula.

    Temporomandibular joint (TMJ) disc derangement is defined as a malpositioning of the articular disc relative to the condyle and eminence. Arthrocentesis of the TMJ is a minimally invasive chair side procedure for the patients with TMJ internal derangement. This case report presents convincing results to keep arthrocentesis as an imperative procedure to relieve such patients of their acute symptoms. TMJ dynamics has also been discussed for an in-depth understanding of the pathology in cases with internal derangement.

    To determine the relationship between clinical symptoms and magnetic resonance (MR) images in patients presenting with temporomandibular joint (TMJ) disorders. This study was based on 172 joints in 86 patients presenting with TMJ disorders. Joint pain and sound during jaw opening and closing movements were recorded, and the possible relationship between disc positions and bony changes of the condylar head and the articular fossa in MR images in the oblique sagittal planes were examined. Data were analyzed by Chi-square test. There was no statistically significant relationship between clinical symptoms and MR images in the patients with TMJ disorders. In the patient with TMJ disorders, joint pain and sound could not be specific clinical symptoms that are related with MR image findings, and asymptomatic joint did not necessarily imply that the joints are normal according to MR image findings.

    In the field of orthopedics, CT arthrography has been utilized for the shoulder and the knee joints diagnosis. In this study, CT arthrography was applied to the temporomandibular joint (TMJ) and the usefulness of this method was evaluated experimentally and clinically. In the experimental study, CT, CT arthrography and arthrotomogtaphy were compared each other with serial section from human autopsy specimen. It was confirmed that arthrography was indispensable for diagnosis of the location and configuration of the articular disk. In the sagittal section, CT arthrography was almost equal to arthrotomography. But in the coronal section, CT arthrography proved to be advantageous to arthrotomography, because there were various blur images on the arthrotomographic images from the complex bony structures of the skull. In the clinical study, coronal CT arthrography was applied for the patients with internal derangements of the TMJ. The mesio-lateral displacement of the disk (62%), perforation of the attachment (23%), and the intra-articular adhesion (70%) could be diagnosed. BY CT arthrography, the mesio-lateral displacement of the disk was more clearly diagnosed and the intra-articular adhesions were proved with higher rate than by the arthrotomography. From this study, it was concluded that CT arthrography has an important role in diagnosis of the TMJ soft tissue. (author) 51 refs.

    Temporomandibular dysfunctions (TMD) comprise a great number of disruptions that may affect the temporomandibular joint (TMJ), the masticatory muscles, or both. TMJ internal derangement is a specific type of TMD, of which the etiology and physiopathology are broadly unknown, but have been suggested to be linked to head, neck, and body posture factors. This study aimed at verifying possible relationships between body posture and TMJ internal derangements (TMJ-id), by comparing 30 subjects presenting typical TMJ-id signs to 20 healthy subjects. Subjects' clinical evaluations included anamnesis, stomatognatic system evaluation, and plotting analysis on body posture photographs. No statistically significant differences were found between the groups. Results do not support the assertion that body posture plays a role in causing or enhancing TMD; however, these results should be cautiously considered because of the small number of subjects evaluated and the many posture variables submitted to statistical procedures that lead to high standard deviations.

    Twenty-five postmeniscoplasty temporomandibular joints (TMJs) were studied in 20 patients. In all patients, preoperative MR images showed anteriorly dislocated disks. The patients underwent a similar postoperative MR examination 4-12 months after surgery. Surgical results were classified clinically as either poor, fair, good, or excellent at the time of the follow-up MR imaging. Forty percent of patients had good or excellent clinical results, and 60% had poor or fair results. The good/excellent group all had disks that appeared to be in normal or near normal position. Almost all disks were fixed in position. The degree of condylar translation was variable. The poor/fair group all had postoperative joints with anteriorly dislocated disks that were fixed in place. Recapture of the disk was variable, as was the degree of condylar translation

    The aim of this evaluation was to examine correlations between internal derangement of the temporomandibular joint (TMJ) and cervical spine disorder (CSD). A prospective controlled clinical study was carried out. Thirty patients with signs and symptoms of internal derangement but without any subjective neck problems and 30 age- and gender-matched control subjects without signs and symptoms of internal derangement were examined. The investigation of the temporomandibular system was carried out using a 'Craniomandibular Index'. Afterwards an examiner-blinded manual medical investigation of the craniocervical system was performed. This included muscle palpation of the cervical spine and shoulder girdle as well as passive movement tests of the cervical spine, to detect restrictions in the range of movement as well as segmental intervertebral dysfunction. The internal derangement of the TMJ was significantly associated with 'silent' CSD (t-test, P temporomandibular system exhibited significantly more often pain on pressure of the neck muscles than patients without muscle tenderness of the temporomandibular system (t-test, P < 0.05). As a result of the present study, for patients with internal derangement of the TMJ an additional examination of the craniocervical system should be recommended.

    Postoperative management of patients suffering from symptoms of the temporomandibular joint does not differ considerably from the one of preoperative examination protocols. Knowledge of previous surgery helps to plan patient work-up and to interpret normal postoperative findings (eminectomy, discectomy, susceptibility artefacts from metallic residues..) and typical complications (intraarticular loose bodies, dislocations, avascular necrosis, foreign body granulomatous reactions) appropriately.

    The Carey-Finema-Ziter syndrome (CFZS, MIM 254940) is an apparently autosomal recessively inherited disorder consisting of the combination of non-progressive congenital myopathy with Moebius and Pierre Robin sequence, facial anomalies and growth delay. Mental development has been described as normal or delayed. Temporomandibular joint (TMJ) ankylosis is the immobility of the joint caused by ankylotic fusion of the mandible to the cranial base or zygoma. It is a serious and disabling condition that may cause problems in mastication, digestion, speech, appearance, and oral hygiene. Most often is a true ankylosis of the TMJ but other pathological mechanisms are described (i.e., the fusion of the coronoid process to temporal bone or with the zygoma, or a variety of soft tissues disorders like Fibrodysplasia Ossificans Progressiva). Here we report a 2-year-old girl fitting with a clinical diagnosis of CFZS associated with a limited mouth opening in which temporomandibular joint ankylosis was suspected. Because it has been postulated that many clinical features in CFZS may only be secondary effects of brainstem anomalies and muscle weakness during development, the limited opening of the mouth observed in our patient could represent a rare clinical feature of CFZS itself. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Bennatan Ferreira dos Santos

    Full Text Available Abstract Introduction: The instrumental practice for a long time, the high performance level, the strict technique and the specific shape of each musical instrument can take musicians to overcome their physiological limits, giving a high prevalence of musculoskeletal injuries. Objective: Investigate the prevalence of temporomandibular joint disorder and neck pain in musicians. Methods: Between August and September 2015 were reviewed five databases: LILACS, SciELO, Medline / PubMed, Scopus and Web of Science. The articles were read and evaluated by the criteria of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE, items, that obtained a percentage above of 50 percent, were considered in the analysis of this work. Results: 15 articles attended the inclusion criteria. Among all musicians the prevalence of TMJ pain ranged from 10 - 81% and the prevalence of neck pain ranged from 29 - 80%. Conclusion: In this study was observed that the musicians showed both, temporomandibular joint disorders and neck pain, watching a high prevalence especially in violinists and the horn players. In the risk factors identified in the literature for the emergence of painful symptoms in musicians, stand out the biomechanical factors involved in maintaining anti-physiologic postures.

    This review described lesions of articular disk and its surrounding tissues revealed by MR examination in temporomandibular arthrosis, and problems and limits of the examination. Apparatus and imaging methods: Spin echo method was generally used and gradient echo method was alternatively used. Author`s apparatus was 1.5 tesla Signa, Advantage type, equipped with surface coil for temporomandibular joint. Imaging conditions were T1-weighted spin echo method, T2-weighted fast spin echo method, spoiled GRASS (gradient recalled acquisition in the steady state) method and GRASS method. MR findings of articular disk: MR images of normal and abnormal temporomandibular joint were presented together with computed radiographic findings. The role of dynamic imaging was described for evaluation and analysis of the joint functioning. MR findings of surrounding tissues of the disk: Dynamic MRI of the tissues was found useful to see whether the cause of pain was present inside or outside of the articular capsule. Joint effusion could not be fully imaged in T2-weighted conditions. (K.H.)

    The sensory innervation of the temporomandibular joints (TMJs) of 8 STR/IN mice was investigated by means of light and electron microscopy. Through the cutting of complete semithin sections in series it was possible to investigate the joints thoroughly. Additionally, one joint with its nerve supply was reconstructed three-dimensionally with a computerized three-dimensional programme. The reconstruction was based on one complete semithin section series. The joint's nerve supply originates from the nervus auriculotemporalis and additionally from motor branches of the n. mandibularis: n. massetericus, n. pterygoideus lateralis and the nn. temporales posteriores. The greatest number of nerve fibres and endings is located in the dorsolateral part of the joint capsule. They lie only in the stratum fibrosum and subsynovially. Neither the stratum synoviale nor the discus articularis contain any nerve fibres or endings, whereas the peri-articular loose connective tissue is richly innervated. The only type of nerve ending observed within the joint was the free nerve ending, which is assumed to serve not only as a nociceptor but also as a polymodal mechanoreceptor. Merely within the insertion of the musculus pterygoideus lateralis at the collum mandibulae single stretch receptors of the Ruffini type were observed. Ultrastructurally, they correspond to those described in the cat's knee joint. Neither lamellated nor nerve endings of the Golgi or Pacini type were observed in the joint or in the peri-articular connective tissue. The unexpected paucity of nerve fibres and endings in the TMJ itself of the mouse suggests that the afferent information from the joint is less important for position sense and movement than the afferent information from muscles, tendons and periodontal ligaments.

    A prospective study to determine the accuracy of computed tomography (CT) for the diagnosis of dislocation of the temporomandibular joint (TMJ) meniscus was made by performing both CT and contrast arthrography on 18 joints suspected of meniscus dislocation. Arthography rather than surgery was chosen as the quality standard for comparing CT findings, as not all patients undergoing the studies underwent surgery. The results of each test were reported independently by the radiologist who obtained either all of the arthograms or all of the CT scans. For dislocation of the meniscus, there were excellent agreement between the two methods. CT seems to be nearly as accurate as arthrography for showing meniscus dislocation, is performed with lower x-ray exposure, and is noninvasive. Arthrograpy discloses more detailed information about the joint meniscus, such as perforation and maceration, and should continue to be used when this kind of information is clinically important

    Correction of severe malocclusions with skeletal discrepancies requires orthodontic treatment in combination with orthognathic surgery. Even though conventional orthognathic surgery (COS) is a common and well-accepted approach its influence on the signs and symptoms of temporomandibular disorders (TMDs) is still debated. Recently with the introduction of surgery first approach, a different timing for the management of dentoskeletal imbalances has been proposed. The present study is aimed at assessing the relationship between surgery first approach and temporomandibular joint (TMJ) disorders. The study sample consisted of 24 patients who were selected to be treated with surgery first approach. Clinical follow-ups after surgery were performed every week for the first month, at 3 months, 6 months, and at 1 year. A radiological follow-up was performed at 1 week and at 1 year after the operation with a panorex and a latero-lateral teleradiograph. To assess the effect of surgery first approach on the TMDs signs and symptoms, a clinical assessment was performed 4 days before surgery (T1), 6 months after surgery (T2), and 1 year postoperatively (T3). The results of the authors' study show that pain assessment revealed a general improvement of this symptom in correspondence to TMJ and masticatory muscles except in the masseter and neck region. Also joint noises, TMJ functioning, migraine, and headache underwent a considerable improvement. Surgery first approach is an innovative orthognathic procedure and, by undergoing surgery first approach, patients with pre-existing TMJ dysfunction may experience a significant improvement or even resolution of the TMDs signs and symptoms.

    Acute dislocation of the temporomandibular joint is a situation that, although rare, may present to the dentist in practice at any time. A number of activities, such as removal of a tooth, may cause dislocation. The event is painful and distressing for the patient, their family and the dental team. Prompt management minimises discomfort, distress and long-term morbidity to the patient. We describe the aetiology of acute dislocation and outline a number of techniques that will aid the clinican in dealing with this event.

    The author presents an attempt of using ultrasonographic technique in diagnosis, planning and observation of treatment results of temporo-mandibular joint pain dysfunctions. Temporo-mandibular joint pain dysfunctions are interchangeably also called temporo-mandibular joint functional disorders. The assessment of pain symptoms in temporo-mandibular joint dysfunctions pain symptoms is principally based on a subjective estimation by the examining practitioner. There is no univocal definition of the disease or a simple index evidencing important symptoms in decision making. Additionally X-ray technique examinations, being hitherto used, in early stages of the disorder do not allow to diagnose it, and are also burdensome to a patient. The aim of this study was to confirm visibility of anatomical elements of the temporo-mandibular joint in an ultrasound examination, assess the mobility of the articular disc before, during and after prosthetic treatment with and without the use of ultrasound technique, and to determine the period of time necessary to obtain a therapeutic effect. The study material consisted of 180 patients, 128 women and 52 men, aged 20 to 60 years, treated by applying prostheses because of temporo-mandibular joint pain dysfunction, in the Department of Prosthetic Dentistry of the Pomeranian Medical Academy. The patients were divided into 2 groups, control and study group. The control group consisted of 90 patients, 63 women and 27 men. In this group prosthetic treatment planning and observation of results was based on a subjective estimation of the practitioner. The study group here comprised 90 patients, 65 women and 25 men, aged 26 to 60 years. In this group prosthetic treatment planning and observation of treatment results were carried on with the use of ultrasound technique. Data from both groups concerning history, results of examinations carried out by ultrasound technique, and the assessment of ultrasound examination were noted on standard

    Full Text Available Abstract Introduction: Temporomandibular joint disorders (TMD are the most common disorders of the jaw, and despite their clinical importance, they are not completely understood. This study was aimed to evaluate the changes of temporomandibular joint (TMJ on cone beam computed tomography (CBCT images in disc displacement vs. osteoarthritis of the TMJ. Methods: In this study, 45 patients, including 37 women and 8 men (13-89 years of age, were examined. The patients were selected based on RDC/TMD criteria and group I disorders were excluded from the study. Accordingly, group II consisted of 43 joints with jaw clicking or displaced discs, and group III comprised 46 joints with crepitus. CBCT images in sagittal, coronal, and axial sections were examined to assess osseous changes in terms of flattening, sclerosis, erosion, resorption, and osteophyte formation. Data were analyzed using statistical tests including the chi-square, Mann-Whitney, and Kolmogorov-Smirnov tests with the confidence interval of 95%. Results: Mann-Whitney test for the comparison of mean age between groups II and III was not statistically significant (p value=0.06. A significant differences was found between two (RDC/TMD groups according to the prevalence of condylar erosion, resorption, and osteophyte (p

    A standardized CT procedure for examination of the temporomandibular joint (TMJ) with axial and coronal scanning as well as reformatted coronal and sagittal sections, was performed on 32 adults. These included subjects with normal TMJ and patients suffering from muscular dysfunction/disc displacement, arthrosis or rheumatoid arthritis. Some normal CT appearances simulating disease were presented. Axial CT scanning appeared to be the most useful method for demonstrating osseous abnormalities of the TMJ. The diagnostic information was occasionally supplemented by the coronal scanning, which may be difficult to perform on patients with neck stiffness. Reformatted coronal or sagittal sections mostly confirmed TMJ abnormality and supplemented the findings at axial scans in about one third of the patients. (orig.)

    The purpose of this study was to evaluate and review the diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value of imaging diagnosis for temporomandibular disorders. The role of diagnostic imaging is to detect and document specific anatomic abnormalities associated with the signs and symptoms in the temporomandibular joint. Magnetic resonance imaging (MR imaging) can accurately depict disc displacement and disc deformity. MR imaging is our first choice among the various imaging modalities for the patients with clinical signs and symptoms. However, it has been shown that intra-capsular adhesions and perforations of the disc and retrodiscal tissue are sometimes not detected by MR imaging. To improve the diagnostic technique for adhesions and perforations, double-contrast arthrotomography with fluoroscopy should be employed. The irregular surface of the eminences and the glenoid fossae shown by MR imaging and tomography are correlated with subchondral bone exposure by arthroscopy. Erosion of the condyles detected by MR imaging, tomography and rotational panoramic radiography is correlated with subchondral bone exposure detected by arthroscopy. (author). 69 refs

    Aim: To describe condylar deformation in the temporomandibular joint (TMJ) in subjects with idiopathic condylar resorptions (ICR) and compare these changes to a healthy control group. Materials and method: CBCT scans were analyzed using anatomical points on the skull to create a reference line....... Subsequently, anatomical structures were identified on the mandible to measure the condylar axial angle, the condylar neck angle as well as the condylar width, length, and height in 25 patients with ICR and 25 controls (50 joints in each group). Secondly, cross sections of the TMJs were evaluated for deformity...... %), cavitation defect (22 %), and flattering (22 %). In the control group condylar flattening was seen in 2 %. More than 70 % of the joints with deformity changes evaluated in the sagittal and the coronal plane respectively showed deformity changes along the entire condylar surface. Conclusion: The results...

    The objective of this study was to determine the extent to which altered loading in the temporomandibular joint (TMJ), as might be associated with a malocclusion, drives degeneration of articulating surfaces in the TMJ. We therefore sought to quantify the effects of altered joint loading on the mechanical properties and biochemical content and distribution of TMJ fibrocartilage in the rabbit. Altered TMJ loading was induced with a 1mm splint placed unilaterally over the maxillary and mandibular molars for 6 weeks. At that time, TMJ fibrocartilage was assessed by compression testing, biochemical content (collagen, glycosaminoglycan (GAG), DNA) and distribution (histology), for both the TMJ disc and the condylar fibrocartilage. There were no changes in the TMJ disc for any of the parameters tested. The condylar fibrocartilage from the splinted animals was significantly stiffer and the DNA content was significantly lower than that in control animals. There was significant remodeling in the condylar fibrocartilage layers as manifested by a change in GAG and collagen II distribution and a loss of defined cell layers. A connection between the compressive properties of TMJ condylar fibrocartilage after 6 weeks of splinting and the changes in histology was observed. These results suggest a change in joint loading leads to condylar damage, which may contribute to pain associated with at least some forms of TMJ disease. Copyright © 2014 Elsevier Ltd.

    The use of artificial joint implants has risen greatly over the past years. However, few investigations of the cancer risk associated with implants have been performed. We investigated cancer risk in patients with finger and hand joint and temporo-mandibular (TMJ) joint implants. A nationwide cohort in Denmark of patients with finger and hand joint prostheses (n = 858) or TMJ implants (n = 389) was followed from January 1, 1977, to December 31, 1995, to evaluate any potential cancer risks subsequent to receiving these implants. Standardized incidence ratios (SIRs) for all cancers were 1.0 (95% CI = 0.8-1.2) for the finger and hand joint cohort and 1.1 (95% CI = 0.8-1.7) for the TMJ cohort. A significant risk for non-Hodgkin's lymphoma was found in the finger and hand joint cohort (SIR = 3.8, 95% CI = 1.5-7.8). When the finger and hand joint cohort was stratified by diagnosis of rheumatoid arthritis, the excess risk was seen only in the group with rheumatoid arthritis. This is consistent with past studies, which have found an association between rheumatoid arthritis and non-Hodgkin's lymphoma. Our results provide evidence that the cancer risk for patients with finger and hand joint prostheses and TMJ implants is similar to that for the general population.

    Full Text Available Drug induced dystonic reactions are among common presentations of patients in emergency departments, and typically occur with antidopaminergic agents as their extra-pyramidal side effects. Dystonic reactions usually occur within the first few hours or days after commencing a drug or dose increase. Unlike other extra-pyramidal side effects, a patient may experience acute dystonic reactions (ADRs with the administration of just a single dose. Oromandibular dystonia is a subtype of dystonia which can present with perioral manifestations. In extreme cases, it can lead to temporomandibular dislocation. Haloperidol, as a high potent typical antipsychotic drug, can induce dystonia with blocking D2 dopamine receptors. The present paper reports a case of bilateral dislocation of temporomandibular joint following ingestion of haloperidol in a suicidal attempt in a 17 years old girl.

    Full Text Available Internal derangements of the temporomandibular joint are conditions in which the articular disc has become displaced from its original position the condylar head. Relevant anatomic structures and their functional relationships are briefly discussed. The displacement of the disc can result in numerous presentations, with the most common being disc displacement with reduction (with or without intermittent locking, and disc displacement without reduction (with or without limited opening. These are described in this article according to the standardized Diagnostic Criteria for Temporomandibular Disorders, as well as the less common posterior disc displacement. Appropriate management usually ranges from patient education and monitoring to splints, physical therapy, and medications. In rare and select cases, surgery may be necessary. However, in for the majority of internal derangements, the prognosis is good, particularly with conservative care.

    The aim of this study was to determine the frequency and relationship between disk position and degenerative bone changes in the temporomandibular joints (TMJ), in subjects with internal derangement (ID). MRI and CT scans of 180 subjects with temporomandibular disorders (TMD) were studied. Different image parameters or characteristics were observed, such as disk position, joint effusion, condyle movement, degenerative bone changes (flattened, cortical erosions and irregularities), osteophytes, subchondral cysts and idiopathic condyle resorption. The present study concluded that there is a significant association between disk displacement without reduction and degenerative bone changes in patients with TMD. The study also found a high probability of degenerative bone changes when disk displacement without reduction is present. No association was found between TMD and condyle range of motion, joint effusion and/or degenerative bone changes. The following were the most frequent morphological changes observed: flattening of the anterior surface of the condyle; followed by erosions and irregularities of the joint surfaces; flattening of the articular surface of the temporal eminence, subchondral cysts, osteophytes; and idiopathic condyle resorption, in decreasing order.

    For the study of the temporomandibular joint in rheumatoid arthritis 30 patients were selected who were diagnosis as rheumatoid arthritis through the clinical, radiographic examination and laboratory finding. Temporoman dibular 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 1 inch 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.

    Although temporo-mandibular joint (TMJ) ankylosis is one of the most common pathologies afflicting the facial skeleton, it is also the most overlooked and under-managed problem in children. The TMJ forms the very cornerstone of cranio-facial integrity and hence its ankylosis in growing children adversely affects the growth and development of the jaws and occlusion. Impairment of speech, difficulty in mastication, poor oral hygiene, rampant caries and acute compromise of the airway pose a severe psychologic burden on the tender minds of children. The aim of this article is to present an overview of efficient management strategies, based on a case report, so as to increase its awareness among all dental surgeons involved in the treatment of children.

    2001-01-01

    Since its introduction in the 1980s, magnetic resonance imaging has become the preferred method for diagnosing soft tissue abnormalities of temporomandibular joint (TMJ). MR imaging is non-invasive and more accurate than arthorography. In addition, it requires less operator skill and is well tolerated by patients. We are usually taking MR images of the TMJ with the fast spin echo technique that can simultaneously obtain both T2-weighted and proton density images. The purpose of this study was to determine the utility of T2-weighed and proton density images for diagnosing the disk status in TMJ, comparing the results with those obtained by T1-weighted images. We studied 104 TMJs in 52 patients with both T2-weighted and proton density images, and 80 TMJs in 40 patients with only T1-weighted images. The joints were evaluated by two oral radiologists who looked at three aspects of the joints-disk displacement, disk reduction and disk shape - giving ratings of good'' or ''fair'' in each category. Ratings of ''good'' were significant higher in all three categories in T2-weighted and proton density images than in T1-weighted images (p<0.01). Based on these results, we conclude that T2-weighted and proton density images taken with the fast spin echo technique are useful for diagnosing the disk status of the TMJ. (author)

    Comparison between orthopantomography, conventional radiography and lateral tomography for diagnosing arthritic lesions in the temporomandibular joints of 42 children with juvenile rheumatoid arthritis showed that each method seems to have diagnostic limitations. Concordance values of about 70 per cent were obtained. Most often destructive lesions of both the mandibular head and the fossa were observed at tomography. Secondary arthrosis, particularly sclerosis of the fossa, was most often diagnosed at conventional radiography. A combination of radiographic techniques seems to be most reliable for diagnosing arthritic joint abnormalities in children. (Auth.)

    1988-01-01

    Triple correlation of MR imaging with arthrography, arthroscopy, and open surgery was performed in 24 patients (34 temporomandibular joints) with ages ranging from 17 to 66 years. MR imaging showed disk position and morphologic features accurately in 30 joints (88%). It was false negative in one joint and false positive in three joints (9%). Degenerative changes were accurately detected with MR imaging, arthrography, and arthroscopy. Adhesions were diagnosed with arthrography in eight joints, arthroscopy in 14, and MR imaging in none. Disk perforations seen at open surgery were not detected with MR imaging. In conclusion, there is an overlap of information presented by various modalities. MR imaging is better than arthrography detecting disk morphologic features and displacement. Arthrography may add information by showing meniscal dynamics. Arthroscopy entails direct observation of superior joint space only and can detect adhesions and perforations better, but it may alter disk position and dynamics. In the more difficult cases, triple correlation may be needed, as modalities can be complementary

    Temporomandibular joint dysfunction are often accompanied by symptoms of headache such as tension-type headache which is the most frequent spontaneous primary headache. Masseter muscle pain is commonly reported in this group. The purpose of the study was to assess the efficiency of intramuscular botulinum toxin type A injections for treating masseter muscle pain in patients with temporomandibular joint dysfunction and tension-type headache. This prospective outcome study consisted of 42 subjects of both genders aged 19-48 years diagnosed with masseter muscle pain related to temporomandibular joint dysfunction and tension-type headache. The subjects were treated by the intramuscular injection of 21 U (mice units) of botulinum toxin type A (Botox, Allergan) in the area of the greatest cross-section surface of both masseter bellies. Pain intensity was evaluated using visual analogue scale (VAS) and verbal numerical rating scale (VNRS) 1 week before the treatment and 24 weeks after the treatment. The obtained data were analyzed using the Wilcoxon matched pairs test (p ≤ 0,005). The results of this study showed a decrease in the number of referred pain episodes including a decrease in pain in the temporal region bilaterally, a reduction of analgesic drugs intake as well as a decrease in reported values of VAS and VNRS after injections (p = 0,000). The intramuscular botulinum toxin type A injections have been an efficient method of treatment for masseter muscle pain in patients with temporomandibular joint dysfunction and tension-type headache.

    Full Text Available Intubating a patient with temporomandibular joint ankylosis is always a challenge particularly when fibreoptic laryngo-scope is not available. In a 20-year-old male patient we successfully carried out endotracheal intubation with 7 mm portex cuffed PVC tube with the help of two flexible J tipped guide wires. One guide wire was passed into the airway from cricothyroid puncture site and another from subcricoid site. Both were brought out through the nose. The first guide wire was used for retracting the epiglottis and the second as a guide for passing the endotracheal tube.

    The aim of the present study was to assess the relationship between temporomandibular joint disorder (TMJD) and headache in children and adolescents. A prospective cross-sectional cohort study was carried out involving 93 children and adolescents (6 to 14 years of age) at the outpatient service of a dental school. All participants underwent a clinical examination involving Axis 1 of the Research Diagnostic Criteria for Temporomandibular Disorders, along with a characterization of headache and an anthropometric evaluation. Statistical analysis involved the chi-squared test for quantitative variables and the Student's t-test, ANOVA and Tukey's test for quantitative data. An adjusted logistic regression model was used to determine significant associations among gender, age, TMJD and headache. Mild TMJD was identified in 35.8% of the sample and was not associated the presence of headache. Moderate TMJD was found in 25.8% of patients and severe TMJD was found in 11.8%; both forms of TMJD were associated with headache. A significant correlation was found between the intensity of TMJD and the risk of headache. The present findings demonstrate a positive correlation between TMJD and headache in children and adolescents, independently of gender and age.

    Temporomandibular joint pain dysfunction syndrome (TMJPDS) is the most common temporomandibular disorder. This condition presents with symptoms of pain, restricted jaw movement and joint noise. Other symptoms include otalgia, headache, neck pain and trismus. To determine the pattern of Temporomandibular joint pain dysfunction syndrome patients managed at the Lagos University Teaching Hospital, Lagos, Nigeria. A descriptive study of patients with signs and symptoms of Temporomandibular joint pain dysfunction syndrome attending the Oral Medicine Clinic of Lagos University Teaching Hospital. Twenty-one patients with Temporomandibular joint pain dysfunction syndrome were enrolled into the study, out of which 10(48%) were females and 11(52%) were males. The age range was 23-81years with a mean of 45.2 ± 18.9 years. Majority of the patients 20(95.2%) complained of pain around the joint, in the pre-auricular region, in the muscles of mastication and the ear. While 7(35%) complained of clicking sounds, 10(47.6%) complained of pain on mouth opening and during mastication only. In all 5(23.8%) had impaired movement of the jaws, mouth opening was normal in 18(85.7%) but reduced in 3(14.3%) patients. Over half of patients 12(57%) experienced clicking sounds, there was tenderness around the temporomandibular joint in 16(76.2%) cases, pain in the ear of 7(33.3%) patients and 13(61.9%) people presented with tenderness of the muscles of mastication. Conservative management of all the cases resulted in resolution of the symptoms. Temporomandibular joint pain dysfunction syndrome has diverse clinical presentation and though distressing, it responds to prompt and effective conservative management.

    The classical technique for temporomandibular joint (TMJ) arthrocentesis provides a double access to the joint space, which may lead to patient's postoperatory discomfort. For this reason, a less invasive, single-needle approach has been recently described, and the present investigation reports findings on a case series of patients with TMJ osteoarthritis treated with hyaluronic acid injections following a single needle arthrocentesis. METHODS. Fourteen consecutive patients with a diagnosis of TMJ osteoarthritis according to the Research Diagnostic Criteria for Temporo-mandibular Disorders were treated with a cycle of five weekly injections of hyaluronic acid after arthrocentesis. A number of subjective (pain at rest and mastication, masticatory efficiency, functional limitation, subjective efficacy of treatment, tolerability of treatment) and objective (maximum assisted and unassited mouth opening, protrusive and laterotrusive movements) outcome variables were assessed before and after the treatment period. At the end of the five-injection protocol, significant improvements were showed in almost all the subjective outcome variables. Tolerability of the treatment was good on a four-point ordinal scale since the time of the first injection. The present investigation suggested that the single needle technique for TMJ hyaluronic injection following arthrocentesis in osteoarthritic joints may have promising applications in the clinical setting, which have to be confirmed with future studies.

    One hundred and ten patients with psoriatic arthritis (PA) and 100 matched control patients were examined by using orthopantomography to discover radiographic changes in the condyle of the temporomandibular joint (TMJ). 31% of the PA patients and 13% of the control patients had radiographic changes in the condyle of the TMJ. The most common radiographic finding in PA patients was unilateral erosion of the condyle. Of the radiographic changes in the PA group, cortical erosions correlated negatively with age, whereas osteophytes correlated positively with the duration of PA. (orig.)

    Microwave plasma chemical vapour deposition of nanostructured diamond films was carried out on curved surfaces of Ti-6Al-4V alloy machined to simulate the shape of a temporomandibular joint (TMJ) dental implant. Raman spectroscopy shows that the deposited films are uniform in chemical composition along the radius of curvature of the TMJ condyle. Thin film x-ray diffraction reveals an interfacial carbide layer and nanocrystalline diamond grains in this coating. Nanoindentation hardness measurements show an ultra-hard coating with a hardness value of 60{+-}5 GPa averaged over three samples. (rapid communication)

    Personalized prosthetic joint replacements have important applications in cases of complex bone and joint conditions where the shape and size of off-the-shelf components may not be adequate. The objective of this study was to design, test and fabricate a personalized 3D-printed prosthesis for a patient requiring total joint replacement surgery of the temporomandibular joint (TMJ). The new 'Melbourne' prosthetic TMJ design featured a condylar component sized specifically to the patient and fixation screw positions that avoid potential intra-operative damage to the mandibular nerve. The Melbourne prosthetic TMJ was developed for a 58-year-old female recipient with end-stage osteoarthritis of the TMJ. The load response of the prosthesis during chewing and a maximum-force bite was quantified using a personalized musculoskeletal model of the patient's masticatory system developed using medical images. The simulations were then repeated after implantation of the Biomet Microfixation prosthetic TMJ, an established stock device. The maximum condylar stresses, screw stress and mandibular stress at the screw-bone interface were lower in the Melbourne prosthetic TMJ (259.6MPa, 312.9MPa and 198.4MPa, respectively) than those in the Biomet Microfixation device (284.0MPa, 416.0MPa and 262.2MPa, respectively) during the maximum-force bite, with similar trends also observed during the chewing bite. After trialing surgical placement and evaluating prosthetic TMJ stability using cadaveric specimens, the prosthesis was fabricated using 3D printing, sterilized, and implanted into the female recipient. Six months post-operatively, the prosthesis recipient had a normal jaw opening distance (40.0 mm), with no complications identified. The new design features and immediate load response of the Melbourne prosthetic TMJ suggests that it may provide improved clinical and biomechanical joint function compared to a commonly used stock device, and reduce risk of intra-operative nerve damage

    Magnetic resonance (MR) imaging of the temporomandibular joint (TMJ) has now been established as a procedure of choice in the evaluation of TMJ disorders. In this study, we evaluated the dynamics of TMJ motion on MR imaging, which resembles arthrography. Sixty-eight TMJs in 38 symptomatic patients and one healthy volunteer were examined using pseudodynamic images with gradient echo sequences using a 0.5 Tesla MR unit and 8 cm circular planar surface coil. For depiction of each compartment of the meniscus, the optimum sequence was 200/15/2 (TR/TE/excitations) with 50 deg or 60 deg flip angle in gradient refocused acquisition in steady-state (GRASS) sequences. Three contiguous slices on sagittal MR images were routinely obtained at 14-18 different phases of the opening cycle and displayed in closed-loop cine fashion. Internal derangement was observed in 57% of 68 joints. The most common type was anterior meniscal displacement without reduction. Sideway and rotational displacements, observed in 10% each, were noted on both sagittal multislice images and axial reference images. As a pseudodynamic MR technique, jaw movement specifically designed to check bite procedure to adjust splints is useful for detecting the exact time of meniscal redisplacement on the second click. After conservative therapy for arthrosis, pseudodynamic MR provided information on changes in the meniscus and condylar relationship. Pseudodynamic MR with multiple phases is suitable for evaluating subtle motion abnormality of the meniscus and for post-therapeutic monitoring. (author)

    There is no reliable predictor for therapeutic efficacy for temporomandibular joint (TMJ) disease. The aim of the present study was to evaluate the usefulness of Tc-99m HDP bone scan in the pre-therapeutic assessment of prognosis for TMJ disease. Between January 2005 and July 2007, 94 patients (M: F=18: 76; mean age, 33.4±14.0 y) with TMJ disease who underwent pre-therapeutic bone scan were enrolled. Planar bone scan images were obtained at right and left lateral skull areas 3 hours post Tc-99m HDP injection (dose=1295 MBq). TMJ uptake of Tc-99m HDP was quantitated using 13X13 pixel-square region-of-interest over TMJ and parietal skull area as background. TMJ uptake ratio was calculated as; (TMJ background) / background. Asymmetric indices for involved TMJ uptake (Al invovle ) were defined as; TMJ uptake ratio of involved/non-involved joint. Asymmetric indices for greater TMJ uptake regardless of disease involvement (AI greater ) were defined as; TMJ uptake ratio of greater/smaller TMJ uptake. Splint therapy was applied to all patients with mean duration of 7 months (range; 3-34 months). Therapeutic efficacy was dichotomised as improved or non-improved in consideration of mandibular movement, TMJ noise, pain, and tenderness. Seventy-six patients experienced improvement, whereas 18 patients non-improvement. There was no significant difference between improved versus non-improved patients regarding TMJ uptake ratio of involved joint (2.92±0.82 vs. 2.91±0.66), and AI invovle (1.16±0.22 vs. 1.10±0.12) (p>0.05, t-test). However, AI greater was significantly higher in improved patients than non-improved patients (1.20±0.19 vs. 1.13±0.09, p<0.05, t-test). Regardless of disease involvement of TMJ disease, asymmetricities of Tc-99m HDP uptake were more frequently found in improved group after splint therapy. Tc-99m HDP bone scan can predict the efficacy of splint therapy in TMJ disease

    This study was performed to evaluate the relationship between pterygoid plate asymmetry and temporomandibular joint disorders. Cone-beam computed tomography (CBCT) images of 60 patients with temporomandibular disorders (TMD) involving pain were analyzed and compared with images of 60 age- and gender-matched controls. Three observers performed linear measurements of the lateral pterygoid plates. Statistically significant differences were found between measurements of the lateral pterygoid plates on the site that had pain and the contralateral site (p<0.05). The average length of the lateral pterygoid plates (LPPs) in patients with TMD was 17.01±3.64 mm on the right side and 16.21±3.51 mm on the left side, and in patients without TMD, it was 11.86±1.97 mm on the right side and 11.98±1.85 mm on the left side. Statistically significant differences in the LPP length, measured on CBCT, were found between patients with and without TMD (p<0.05). The inter-examiner reliability obtained in this study was very high for all the examiners (0.99, 95% confidence interval: 0.98-0.99). Within the limits of the present study, CBCT lateral pterygoid plate measurements at the side with TMD were found to be significantly different from those on the side without TMD. More research is needed to explore potential etiological correlations and implications for treatment.

    2013-12-01

    Clinicians who address temporomandibular joint (TMJ) pathology and dentofacial deformities surgically can perform the surgery in 1 stage or 2 separate stages. The 2-stage approach requires the patient to undergo 2 separate operations and anesthesia, significantly prolonging the overall treatment. However, performing concomitant TMJ and orthognathic surgery (CTOS) in these cases requires careful treatment planning and surgical proficiency in the 2 surgical areas. This article presents a new treatment protocol for the application of computer-assisted surgical simulation in CTOS cases requiring reconstruction with patient-fitted total joint prostheses. The traditional and new CTOS protocols are described and compared. The new CTOS protocol helps decrease the preoperative workup time and increase the accuracy of model surgery.

    Objective. To evaluate the efficiency of DVT in comparison with OPG in the assessment of bony condylar changes in patients of TMJ pain. Methods. 100 temporomandibular joints of 62 patients with the complaint of temporomandibular joint pain were included in the study. DVT and OPG radiographs were taken for all the 100 joints. Three observers interpreted the DVT and OPG radiograph for the bony changes separately for two times with an interval of one week. The bony changes seen in the condyle were given coding from 0 to 6. (0: Normal, 1: Erosion, 2: Flattening, 3: Osteophyte, 4: Sclerosis, 5: Resorption, and 6: other changes). Interobserver and intra observer variability was assessed with one-way Anoka statistics. Z test was used to see the significant difference between OPG and DVT. Results. In the present study the inter examiner reliability for Og and DVT was 0.903 and 0.978, respectively. Intra examiner reliability for OPG and DVT was 0.908 and 0.980, respectively. The most common condylar bony change seen in OPG and DVT was erosion followed by flattening and osteophyte. There was significant difference between OPG and DVT in detecting erosion and osteophytes. The other changes observed in our study were Elys cyst, pointed condyle, and bifid condyle. All the bony changes are more commonly seen in females than males. Conclusion. DVT provides more valid and accurate information on condylar bony changes. The DVT has an added advantage of lesser radiation exposure to the patient and cost effectiveness and could be easily accessible in a dental hospital

    To investigate the histopathological changes in the temporomandibular joint in streptozotocin-induced diabetic rat following irradiation. Sprague-Dawley rats weighing about 250 gm were divided into three groups: control, diabetic, and diabetic-irradiated groups. Diabetes mellitus was induced in the rats by injecting streptozotocin. Rats in the control group were injected with citrate buffer only. After 5 days, the head and neck region of the rats in diabetic-irradiated group were irradiated with single absorbed dose of 10 Gy. The rats were killed at 1, 3, 7, 14, 21, and 28 days after irradiation. The specimen including the temporomandibular joint were sectioned and observed using a histopathological method. In the diabetic group, severe bone resorption in the mandibular condyle was observed throughout the period of experiment. Necrosis of bone marrow and trabeculae was observed at 28 days after diabetic state. Atrophy and fibrosis in the retrodiscal tissue was gradually progressed during the time of the experiment. In the diabetic-irradiated group, severe bone resorption in the mandibular condyle was observed during the early experimental phases, but regeneration of bone marrow was initiated at 14 days after diabetic state and irradiation. Also, calcification of abnormal trabeculae was observed at 28 days after diabetic state and irradiation. The retrodiscal tissue was degenerated in the early experimental phases, but it had been gradually regenerated during the experimental time. This experiment suggests that bone resorption and degeneration in the mandibular condyle are caused by the induction of diabetes, and abnormal bone formation is induced after irradiation in diabetic state.

    Purpose: The influence of dental alloys on MRI of the temporomandibular joint was studied using a phantom model for this joint. Methods: At 1,5 T, 15 dental alloys and 14 of their most important components were investigated acquiring sagittal (FOV: 150 mm) and transverse (FOV: 250 mm) T 1 -weighted SE additionally. The artifacts were assessed qualitatively as well as quantitatively, and the samples were subdivided into four artifact categories. Results: Ag, Cu, Ga, In, Ti, Sn, Zn, amalgan, the precious alloys, the Au-Pd and Ag-Pd alloys showed no artifacts (category I). Minimal artifacts below 10 mm on transverse images (category II) were found for Cr, Pd, Pt and for the Ni-Cr alloy. Mn and the remaining non-precious alloys induced artifacts up to 30 mm (category III). Significant artifacts - more than 30 mm - (category IV) were to be more susceptible for artifacts than T 1 -weighted SE and FLASH techniques. Conclusions: In contrast to dental alloys for fixed prosthodontics, Ni-Cr- or 18/8 wires used for orthodontic bands can influence not only the image quality, but also the diagnostic reliability of MRI of the temporomandibular joint.

    This study was designed to evaluate the suggestion that the clinical findings and MR image findings of anterior disc displacement with reduction cases could not reduce the disc displacement within the follow-up period. We selected 26 joints without remarkable bone changes in the condylar head or glenoid fossa in which reduction disappeared during follow-up. Clinical evaluation focused on temporomandibular pain, trismus, and joint sound. MR imaging was targeted for configuration of articular disc, degree of disc displacement, and condylar head position. Clinical signs observed with progression of the condition were disappearance of joint sound in 12/26 joints (46.1%), temporomandibular pain in 15/26 joints (57.6%), and decreased distance of opening mouth in 19/26 joints (73%). MR image findings were disc configuration changes in 12/26 joints (46.1%), increased degree of anterior displacement of disc in 20/26 joints (76.9%), and condylar head position changes in 9/26 joints (34.6%). It is suggested that the advanced stage of internal derangement is closely associated with the degree of disc displacement. (author)

    Chronic dislocation of the temporo-mandibular joint (TMJ) is rare. It occurs when an acute dislocation is left untreated, in certain situations, including severe illness, neurologic or psychiatric diseases or prolonged oral intubation. A 79 years old woman, with Meige syndrome, suffered from bilateral dislocation of the TMJ for over 1 year. Surgical repositioning of the mandibular condyles and temporal bone eminectomy were performed. At the 18 postoperative months control, no recurrence has been noted. Treatment of chronic TMJ dislocations often requires a surgical procedure. Manual reduction, even under general anaesthesia, often fails because of severe muscular spasm and periarticular fibrotic changes. The management of this disorder is still controversial. We review available surgical procedures. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    The ectodermal dysplasias are a heterogenous group of diseases, which have one or more anomalies of the hair, teeth, nails, and sweat glands. Hypohidrotic ectodermal dysplasia (HED) is the most common type and is usually transmitted as an X-linked recessive trait. It is characterized by classical triad of hypotrichosis, anhidrosis/hypohidrosis, and hypodontia/anodontia. Here, we describe an Indian boy affected with HED and rare features including ankylosis of temporomandibular joint and cleft palate. PMID:25684924

    Modern health care in the field of Medicine, Dentistry and Nursing is grounded in fundamental philosophy and epistemology of translational science. Recently in the U.S major national initiatives have been implemented in the hope of closing the gaps that sometimes exist between the two fundamental components of translational science, the translational research and translational effectiveness. Subsequent to these initiatives, many improvements have been made; however, important bioethical issues and limitations do still exist that need to be addressed. One such issue is the stakeholder engagement and its assessment and validation. Federal, state and local organizations such as PCORI and AHRQ concur that the key to a better understanding of the relationship between translational research and translational effectiveness is the assessment of the extent to which stakeholders are actively engaged in the translational process of healthcare. The stakeholder engagement analysis identifies who the stakeholders are, maps their contribution and involvement, evaluates their priorities and opinions, and accesses their current knowledge base. This analysis however requires conceptualization and validation from the bioethics standpoint. Here, we examine the bioethical dilemma of stakeholder engagement analysis in the context of the person-environment fit (PE-fit) theoretical model. This model is an approach to quantifying stakeholder engagement analysis for the design of patient-targeted interventions. In our previous studies of Alzheimer patients, we have developed, validated and used a simple instrument based on the PE-fit model that can be adapted and utilized in a much less studied pathology as a clinical model that has a wide range of symptoms and manifestations, the temporomandibular joint disorders (TMD). The temporomandibular joint (TMJ) is the jaw joint endowed with sensory and motor innervations that project from within the central nervous system and its dysfunction can

    To explore the selection of temporomandibular joint (TMJ) disc reduction and fixation methods in condylar sagittal fracture surgery. A total of 36 patients with condylar fractures were chosen. The follow-up period was more 6 months. All 36 cases of condylar sagittal fracture were fixed with long screw. In the operation, the displaced joint disc was repositioned and fixed. The fixed method included direct suture (22 cases) and anchorage (14 cases). Clinical followups were performed before surgery and 1 month, 3 months, 6 months and 1 year after surgery. Clinicians recorded data related to the Fricton craniomandibular index (CMI) and evaluated the postoperative joint function during followup before surgery and 6 months after surgery. In both groups, function of TMJ significantly improved after surgery. The CMI decreased from 0.213±0.162 and 0.273±0.154 to 0.059±0.072 and 0.064±0.068 (P0.05) before or after surgery. Both methods could effectively improve the dysfunction of the TMJ caused by trauma. The selection of joint disc reduction and fixation methods is based on the displacement and damage degree of the joint disc.

Methods: A cross-sectional study carried with 21 patients receiving physiotherapy care during the year of 2007 at the Center for Integrated Medical Care (Núcleo de Atenção Médica Integrada - NAMI, in Fortaleza-CE, Brazil. Those were submitted to anamnesis (age, presence of pain, affected sites and parafunctional habits and functional assessment (presence of trigger points, movement amplitude and postural evaluation. Results: The age varied from 16 to 56 years, with an average of 31.3 ± 14.85 and female gender was the most affected with 17 (81.0% patients. Of the assessed patients, 13 (61.9% presented pain of moderate intensity, with an average of 5.4 ± 0.50. The most common sites of pain were the temporomandibular joint (TMJ, reported by 15 (71.4%,and cervical region, reported by 13 (61.9% patients. We found that 13 (61.9% assessed patients reported clenching as parafunctional habit. Significant limitation of mouth opening and movements of the cervical region were observed when compared to normal values (p <0.05. The most painful muscles on palpation were upper trapezius (n=19, medial pterygoid (n=15 and the masseter (n=15. The TMJ presented strong pain (degree 3 on palpation in 3 (14.3% patients. In postural assessment, 10 (47.6% had cervical hyperlordosis, 7 (33% had forward head posture and 7 (33% had raised shoulders. Conclusion: Patients with TMJD receiving physical therapy present limitations in TMJ and cervical movement, pain, presence of trigger points and postural changes at a more compromised and symptomatic stage of this dysfunction. In view of this, it becomes necessary to provide early evaluation and treatment with physical therapy.

    Although an interaction of malocclusion, parafunction, and temporomandibular joint disorders (TMD) can be inferred from the experience of daily practice, scientific evidence to corroborate this hypothesis does not exist. However, there are indications that TMD and headaches may be intertwined. The purpose of this study was to identify the presence or absence of an association of occlusal interferences, parafunction, TMD, or physiologic, muscular, or prosthodontic factors with the occurrence of headache. In a private practice population of 1031 subjects (436 men and 595 women, mean age 49.6 years) the demographic parameters, headache and general pain history, habits and general personal information were recorded. Clinical examination for dental, muscular, and temporomandibular joint pathology was accomplished. Data were statistically analyzed using the Mann-Whitney U, Kruskal-Wallis, and Chi-Square tests (α = .05). A multinomial logistic regression analysis was performed with respect to confounding variables. Headache affliction was found to affect women more frequently than men (1.7:1). Students and non academics were more prone to suffer from headache. Parafunction (P=.001), TMD (P=.001) and gross differences between centric occlusion and maximum intercuspation of more than a 3 mm visible track marked with 8 μm articulation foil (P=.001) significantly influenced the presence of headache. Headache intensity and frequency decreased with age. While tension-type headache was most frequently diagnosed, the parameters studied were not significantly associated with one certain headache diagnosis more frequently than others. Stomatognathic factors of TMD, parafunction, and gross differences between centric occlusion and maximum intercuspation of more than 3 mm are associated with headache. These findings should be interpreted with caution due to the cross-sectional nature of this study. Copyright © 2011 The Editorial Council of the Journal of Prosthetic Dentistry

    We report a case of a 66-year-old white woman with calcium pyrophosphate dihydrate (CPPD) crystal deposition disease. The patient related a 2-month history of swelling with tenderness over the left pre-auricular region. A CT scan suggested a synovial chondromatosis. Surgical removal was done and histologic study showed CPPD crystals. This disease rarely involves the temporomandibular joint (TMJ) and is not usually considered in the differential diagnosis. To our knowledge, only 14 cases have been reported in the literature. (orig.)

    Full Text Available The temporomandibular joint has a very important role in the stomatognathic system. Its main function is for the opening and closing movement, mastication, and speech. It is located anterior to the ear. The temporomandibular joint connects maxilla and mandible through the articular fossa, hence the slightest change that happens would cause serious matters such as pain, exiting, speech disorder, difficulty in opening and closing movement, headache, and even trismus. In a child or an adolescent, the symptoms are often vague; everything is interpreted as “pain”. This is probably why temporomandibular disorder are often undetected by dentists. Therefore, patience and accuracy is needed to determine the actual disorder through means of clinical and radiographic examination. The radiographic examination suitable for child is the transcranial projection. This projection is believed to be more accurate amongst other projection for child patients.

    The purpose of orthognathic surgery is to correct facial deformity and dental malocclusion and to obtain normal orofacial function. However, there are controversies of whether orthognathic surgery might have any negative influence on temporomandibular (TM) joint. The purpose of this study was to evaluate the influence of orthognathic surgery on articular disc position and temporomandibular joint symptoms of skeletal CI II patients by means of magnetic resonance imaging. For this purpose, fifteen patients with skeletal CI II malocclusion, aged 19-32 years (mean 23 years), 10 women and 5 men, from the Isfahan Department of Oral and Maxillofacial Surgery were studied. All received LeFort I and bilateral sagittal split osteotomy (BSSO) osteotomies and all patients received pre- and post-surgical orthodontic treatment. Magnetic resonance imaging was performed 1 day preoperatively and 3 month postoperatively. Descriptive statistics and Wilcoxon and Mc-Nemar tests were used for statistical analysis. P surgery (mean=5.74±1.21). After surgery disc position range was 4.36 to 7.40 (mean=5.65±1.06). Statistical analysis proved that although TM disc tended to move anteriorly after BSSO surgery, this difference was not statistically significant ( p valuesurgery does not alter the disc and condyle relationship. Therefore, it has minimal effects on intact and functional TM joint. Key words: Orthognathic surgery, skeletal class 2, magnetic resonance imaging, temporomandibular disc.

    Temporomandibular disorders (TMD) are a heterogeneous group of musculoskeletal and neuromuscular conditions involving the temporomandibular joint complex, and surrounding musculature and osseous components. TMD affects up to 15% of adults, with a peak incidence at 20 to 40 years of age. TMD is classified as intra-articular or extra-articular. Common symptoms include jaw pain or dysfunction, earache, headache, and facial pain. The etiology of TMD is multifactorial and includes biologic, environmental, social, emotional, and cognitive triggers. Diagnosis is most often based on history and physical examination. Diagnostic imaging may be beneficial when malocclusion or intra-articular abnormalities are suspected. Most patients improve with a combination of noninvasive therapies, including patient education, self-care, cognitive behavior therapy, pharmacotherapy, physical therapy, and occlusal devices. Nonsteroidal anti-inflammatory drugs and muscle relaxants are recommended initially, and benzodiazepines or antidepressants may be added for chronic cases. Referral to an oral and maxillofacial surgeon is indicated for refractory cases.

    Dislocation of the temporomandibular joint (TMJ) is a thorny problem not only for a patient but also a doctor. Especially for the elderly edentulous patients, it is very hard to treat the condition although there are many surgical and non-surgical procedures. We successfully treated it in two elderly edentulous patients by injection of OK-432 as a sclerosing agent.

    Full Text Available The aims of this preliminary study were to present a modified mandibular splint together with a treatment regimen and to evaluate their effects on the treatment of reciprocal joint sounds of the temporomandibular joint (TMJ. The study participants were recruited from 312 consecutive patients in the temporomandibular disorder clinic of a medical center in Taiwan from January 2003 to December 2003. From among these, 59 cases with typical reciprocal clicking were selected for this study. All participants were treated with a modified mandibular splint and then followed up for 6 months. Successful treatment was defined as leading to the disappearance of the joint sounds of TMJ, as described by patients. Based on clinical evaluation, the overall success rate was 71.2% (42/59 with minimal temporary complications. Patients with clicking at less than 3.5 cm of interincisal opening had a success rate of 92.5%, which was higher than the success rate of patients with clicking at a mouth opening of 3.5 cm or more. This study showed that a modified mandibular splint can be used to treat reciprocal clicking of the TMJ effectively and encouraged us to conduct further study on the efficacy of this splint to treat disc displacement with reduction of TMJ using magnetic resonance imaging examination.

    Purpose: To study the CT depiction of bone demarcations in the temporomandibular joint, using conventional window level and window width; and to evaluate observer performance in estimating bone thickness in these images. Material and Methods: Seven joint specimens were imaged by CT and then cryosectioned. The measurements of bone wall thickness in the images were compared to the true bone thickness at each cutting level. In addition, 4 experienced radiologists estimated the thickness of the bone walls in the images. Results: The relative difference between the CT reproduction and the true bone thickness was small for bone walls thicker than 2 mm. This difference increased with the decrease in bone thickness and the increase in the inclination of the bone wall from the perpendicular to the image plane. Bone walls thinner than 1 mm were reproduced as considerably thicker than their true thickness. This resulted in a clinical overestimation of bone thickness. Conclusion: Both the CT representation and the interpretation of bone demarcation in the temporomandibular joint may constitute a problem. Partial volume averaging effects can result in an overestimation of bone dimensions amounting to 200% for thin bones. The central white zone in images of thin bone walls obtained with the parameters described here could serve as an indicator that could help to reduce the risk of overestimating bone thickness.

The presence or absence of a perforation of the posterior attachment or disk was recorded. Later, tomograms of the same patient were interpreted. The presence or absence of evidence of temporomandibular degenerative joint disease (TMDJD) was recorded. The condyle-to-fossa relationship was characterized as retropositioned or not retropositioned. O the 106 cases with tomographic evidence of TMDJD, 100 (94%) had arthrographic evidence of internal derangement (p less than 0.0001), whereas 47% of the cases with internal derangement (211) had evidence of TMDJD. Perforations were seen in 29 (27%) of the cases with degenerative joint disease and in none (0%) of the cases without TMDJD (p less than 0.001). In cases without TMDJD, 90% of the cases with internal derangement revealed condylar retropositioning (p less than 0.0001). With tomographic evidence of TMDJD present, the relationship between condylar position and disk position was not significant.

    Establishing the patient's clinical diagnosis depends on gathering as much information of the patient and his or her signs and symptoms as possible. This information can be gathered from history, physical and psychological examination, diagnostic analysis. It is also important to look upon pain as a disorder and to consider the relationship between pain and psychological factors. The differential diagnosis is constructed through a biopsychological model of illness rather than through a more traditional biomedical model of disease. To arrive at a consistently accurate clinical diagnosis in patients with TMJ and craniofacial pain, the technique of clinical diagnosis must be well defined, reliable and include examination of the head and the neck, cranial nerves and the stomatognathic system. The craniomandibular index provides a standardized examination of the stomatognathic system that has been tested on validity and reliability. This chapter focuses on the techniques of history taking clinical and psychological examination and diagnostic criteria for temporomandibular joint disorders and muscle pain.

    The purpose of the present study was to explore the potential use of platelet-rich-plasma (PRP) in the treatment of temporomandibular joint osteoarthritis (TMJ-OA). Surgical defects were created bilaterally on the condylar fibrocartilage, hyaline cartilage, and bone to induce an osteoarthritic TMJ in rabbits. PRP was applied to the right joints of the rabbits (PRP group), and the left joints received physiologic saline (control group). After 4 weeks, the rabbits were sacrificed for histologic and scanning electron microscopy (SEM) examinations. The data were analyzed statistically. The new bone regeneration was significantly greater in the PRP group (P fibrocartilage and hyaline cartilage was greater in the PRP group, no statistically significant difference was found between the 2 groups. SEM showed better ultrastructural architecture of the collagen fibrils in the PRP group. PRP might enhance the regeneration of bone in TMJ-OA.

    Purpose: We aimed to assess the contrast enhancement patterns of the retrodiscal tissue with dynamic contrast-enhanced MR imaging (DCE-MRI) with respect to different temporomandibular joint disc pathologies. Additionally, we questioned the relationship between the temporomandibular joint (TMJ) pain and the contrast enhancement pattern of the retrodiscal tissue regardless of the TMJ disc position. Materials and methods: 52 joints of 26 patients (4 males and 22 females) who have pain in at least at one of their TMJ were included in this study. For the qualitative analysis, the joints were divided into four groups in terms of their disc positions: normal (1), partially displaced with or without reduction (2), totally dislocated with reduction (3) and totally dislocated without reduction (4). Besides, two different joint groups were constituted, namely the painful group and painless group according to the clinical findings without taking the TMJ disc positions into account. Quantitative analyses were made by means of measuring signal intensity ratios (SI) ratio at the retrodiscal tissue (from internal side and external side of the each joint) using DCE-MRI and these measurements were analyzed with paired samples t test to define the difference between the measurements. At the second stage, the time-dependent arithmetical mean values of the SI ratios were calculated for each joint group and significant differences between the groups were questioned using analysis of variance (ANOVA) test. Besides, painful and painless groups which were classified on the basis of the clinical data were compared according to the mean SI ratios found for each joint and the significant differences between these two groups were assessed by means of Student's T test. The results were assessed in 95% confidence interval where the significance level was p < 0.05. Results: A significant difference was observed between the internal and external contrast enhancement of the joints with partial

    Background The purpose of orthognathic surgery is to correct facial deformity and dental malocclusion and to obtain normal orofacial function. However, there are controversies of whether orthognathic surgery might have any negative influence on temporomandibular (TM) joint. The purpose of this study was to evaluate the influence of orthognathic surgery on articular disc position and temporomandibular joint symptoms of skeletal CI II patients by means of magnetic resonance imaging. Material and Methods For this purpose, fifteen patients with skeletal CI II malocclusion, aged 19-32 years (mean 23 years), 10 women and 5 men, from the Isfahan Department of Oral and Maxillofacial Surgery were studied. All received LeFort I and bilateral sagittal split osteotomy (BSSO) osteotomies and all patients received pre- and post-surgical orthodontic treatment. Magnetic resonance imaging was performed 1 day preoperatively and 3 month postoperatively. Descriptive statistics and Wilcoxon and Mc-Nemar tests were used for statistical analysis. Psurgery (mean=5.74±1.21). After surgery disc position range was 4.36 to 7.40 (mean=5.65±1.06). Statistical analysis proved that although TM disc tended to move anteriorly after BSSO surgery, this difference was not statistically significant (p valueorthognathic surgery does not alter the disc and condyle relationship. Therefore, it has minimal effects on intact and functional TM joint. Key words:Orthognathic surgery, skeletal class 2, magnetic resonance imaging, temporomandibular disc. PMID:28936287

    The purpose of this study was to assess the tissue alterations in the temporomandibular joint (TMJ) of the New Zealand White rabbit (Oryctolagus cuniculus L.), after a unilateral occlusal interference insertion on the animal's right side back teeth. A total of 36 animals were used, thirty of which belonged to the experimental group and six to the control group. We established three experimental periods: 24 hours, three days and seven days. The control group animals were divided two by two; each pair followed the same experimental periods of the former one. The experimental group animals were submitted to the use of a 0.3 mm thick metallic cap with a visor. All animals were euthanized, and the TMJs were removed. Using a microscope for examination we observed, in all experimental periods, the presence of intra-articular hemorrhage in the supra- and infra-disk compartments as well as in the retro-disk zone. There were no inflammatory cells detected. The thickness of the condylar fibrocartilage presented significant alterations among the animals of the three experimental groups. In the left TMJs no inflammatory cells were detected. The results suggest that the insertion of a unilateral occlusal interference in rabbit back teeth does not cause any inflammatory intra-articular process within seven days; however, it does cause bilateral intra-articular hemorrhage and a larger compression of the condylar fibrocartilage in the joint opposite the side where the interference is placed. We also concluded that, in order to do research on the temporomandibular joint using animals, it is necessary have an independent (or separate) group of animals as controls.

    Purpose. To evaluate the effectiveness of diagnostic and interventional radiological techniques for neoplastic lesions of the temporomandibular joint (TMJ). Material and methods. Modern diagnosis of the TMJ is based on the clinical use of conventional X-ray techniques, computed tomography (CT), magnetic resonance imaging (MRI) and interventional techniques like biopsies, vascular occlusion and ablation. Results. Conventional X-ray still forms the basic diagnostic procedure applied in open and closed mouth position. CT improves the diagnostic information and serves as the standard diagnostical instrument for cartaliganeous or osseous neoplastic lesions. MRI evaluates soft tissue infiltration in multiplanar techniques and high spatial resolution. Interventional vascular and ablative techniques improve the treatment of neoplastic disorders. (orig.)

    Full Text Available Abstract Background Glial cells have been shown to directly participate to the genesis and maintenance of chronic pain in both the sensory ganglia and the central nervous system (CNS. Indeed, glial cell activation has been reported in both the dorsal root ganglia and the spinal cord following injury or inflammation of the sciatic nerve, but no data are currently available in animal models of trigeminal sensitization. Therefore, in the present study, we evaluated glial cell activation in the trigeminal-spinal system following injection of the Complete Freund's Adjuvant (CFA into the temporomandibular joint, which generates inflammatory pain and trigeminal hypersensitivity. Results CFA-injected animals showed ipsilateral mechanical allodynia and temporomandibular joint edema, accompanied in the trigeminal ganglion by a strong increase in the number of GFAP-positive satellite glial cells encircling neurons and by the activation of resident macrophages. Seventy-two hours after CFA injection, activated microglial cells were observed in the ipsilateral trigeminal subnucleus caudalis and in the cervical dorsal horn, with a significant up-regulation of Iba1 immunoreactivity, but no signs of reactive astrogliosis were detected in the same areas. Since the purinergic system has been implicated in the activation of microglial cells during neuropathic pain, we have also evaluated the expression of the microglial-specific P2Y12 receptor subtype. No upregulation of this receptor was detected following induction of TMJ inflammation, suggesting that any possible role of P2Y12 in this paradigm of inflammatory pain does not involve changes in receptor expression. Conclusions Our data indicate that specific glial cell populations become activated in both the trigeminal ganglia and the CNS following induction of temporomandibular joint inflammation, and suggest that they might represent innovative targets for controlling pain during trigeminal nerve sensitization.

    The author analysed the routine radiographic changes and clinical symptoms of 205 cases of temporomandibular joint arthrosis. The clinical symptoms of the patients were classified and the morphological changes of condylar head, articular eminence, and articular fossa were analyzed and discussed from radiographic view point. The positional change of condylar head and articular fossa relation in TMJ arthrosis were observed. The frequencies of coincidence between the site of complaints and the site of the abnormal images which could be detected were examined. The results were obtained as follows; 1. Bone erosion, deformity, marginal proliferation and sclerosis were selected from many abnormal images as the radiographic diagnostic criteria of TMJ arthritic lesions. 2. Abnormal radiographic findings were revealed in 150 cases (73.9%) of 205 total TMJ arthrosis cases and site with abnormal findings coincided with the site of complaints in 105 cases (70.7%) of 150 cases and coincidence rates were higher above fourth decades than below third decades. 3. Sclerosis of the abnormal radiographic findings could be found more often below third decades than above fourth decades. 4. The positional changes of condylar head were revealed in 176 cases (85.9%) of 205 total cases. 5. Pain complaints were revealed in 170 cases(82.9%) and clicking sounds were revealed in 120 cases (58.6%) of clinical symptoms of TMJ arthrosis. 6. No tendency was found so far the differential diagnosis between pain dysfunction syndrome and osteoarthrosis of TMJ.

    Temporomandibular joint (TMJ) ankylosis is characterized by difficulty to open the mouth. The ankylosis may be articular when TJM is involved and extra-articular when other factors lead to a restriction of chewing movements without TJM involvement. Case report of one patient with unilateral ankylosis and his surgical planning through the tomography imaging. CT imaging helps preoperative planning because it can locate the exact point of injury and can make the difference between the true and false ankylosis of the TJM. (author)

    Psychological assessment has been used successfully to predict patient outcomes after cardiothoracic and bariatric surgery. The purpose of this study was to determine whether preoperative psychological assessment could be used to predict patient outcomes after temporomandibular joint arthroscopy. Consecutive patients with temporomandibular dysfunction (TMD) who could benefit from arthroscopy were enrolled in a prospective cohort study. All patients completed the Millon Behavior Medicine Diagnostic survey before surgery. The primary predictor variable was the preoperative psychological scores. The primary outcome variable was the difference in pain between the pre- and postoperative periods. The Spearman rank correlation coefficient and the Pearson product-moment correlation were used to determine the association between psychological factors and change in pain. Univariable and multivariable analyses were performed using a mixed-effects linear model and multiple linear regression. A P value of .05 was considered significant. Eighty-six patients were enrolled in the study. Seventy-five patients completed the study and were included in the final analyses. The mean change in visual analog scale (VAS) pain score 1 month after arthroscopy was -15.4 points (95% confidence interval, -6.0 to -24.7; P psychological factors was identified with univariable correlation analyses. Multivariable analyses identified that a greater pain decrease was associated with a longer duration of preoperative symptoms (P = .054) and lower chronic anxiety (P = .064). This study has identified a weak association between chronic anxiety and the magnitude of pain decrease after arthroscopy for TMD. Further studies are needed to clarify the role of chronic anxiety in the outcome after surgical procedures for the treatment of TMD. Copyright © 2015. Published by Elsevier Inc.

    2001-01-01

    To evaluate displacement and morphologic changes of the temporomandibular joint (TMJ) disc in patient with internal derangement using magnetic resonance imaging (MRI). One hundred and forty five MR images of TMJs in 73 patients were evaluated. Positional and morphologic changes of the TMJ disc were assessed. Lateral or medial disc displacement was also evaluated on cornal images. 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 disc. 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. 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

    In this work, we propose a self-compiled questionnaire, for those patients showing dysfunctions of the temporomandibular joint. The questionnaire, composed by 33 closed multiple-choice questions, represents one of the steps in the diagnostic procedure, together with the clinical notes compiled by the medical specialist and with the other necessary diagnostic researches. It also has the purpose to make easier anamnesis and clinic procedure and gathering of all informations useful for a right clinical diagnosis, and so for an appropriate therapy.

    Findings in 31 pediatric patients with pain and dysfunction of the temporomandibular joint (TMJ) are reported. The average age was 14 years and the average duration of symptoms was 21.4 months. Internal derangements were found in 29 patients (94%) and degenerative arthritis in 13 (42%). In 12 patients (39%), the problem could be traced to an injury to the jaw. Secondary condylar hypoplasia was associated with the meniscal abnormality in 3 patients (10%). Further awareness of internal derangements of the TMJ in the pediatric population should permit greater recognition of their etiology. It is important that threatment be initiated as soon as possible, not only to minimize the development of osseous disease in young adults but also to prevent facial growth deformities

    Many factors have been implicated in the development of bony ankylosis following trauma to the temporomandibular joint (TMJ) or ankylosis that recurs after surgical treatment for the condition. Although many reports have been published, to our knowledge very little has been written about the pathogenesis of the process and there are few scientific studies. Over the last 70 years various treatments have been described. Different methods have been used with perceived favourable outcomes although recurrence remains a problem in many cases, and ankylosis presents a major therapeutic challenge. We present a critical review of published papers and discuss the various hypotheses regarding the pathogenesis of the condition.

    Radiographic findings of the upper and lower jaw bone of 20 adult patients with micrognathia, bird face, and juvenile rheumatoid arthritis are reported. In all patients a symmetrically underdeveloped mandible with the chin posteriorly positioned was found at cephalometry. Arthritic lesion of the temporomandibular joint, mostly symmetric, with limitation of movement and secondary arthrosis, was observed in all patients. Complete absence of the mandibular head was frequent (75%). The fossa was generally flat, probably due to growth disturbance of the tubercle. Abnormal anterior position of the mandibular head occurred in almost half of the patients. The degree of mandibular growth disturbance seemed to be correlated to the severity of the arthritis, indicating the arthritis to be a causal mechanism of micrognathia.

    2005-06-15

    To determine the clinical correlation of magnetic resonance imaging (MRI) findings of temporomandibular joint internal derangements. The MR images of 150 TMJs in 75 patients were analyzed. The clinical symptoms were pain in the pre auricular area and masticatory muscles and TMJ sounds. There was a statistically significant relationship between the MRI diagnoses of different types of disc displacements and clinical findings of pain, clicking, and crepitus. The risk of TMJ pain was increased when the disc displacement without reduction occurred at the same time in combination with the osteoarthrosis and effusion. Regardless of the results, the data indicate that each of these MR imaging variables may not be regarded as the unique and dominant factor in defining TMJ pain occurrence.

    Full Text Available Abstract Background Temporomandibular joint disorders (TMJD are multifactor, complex clinical problems affecting approximately 60–70% of the general population, with considerable controversy about the most effective treatment. For example, reports claim success rates of 70% and 83% for non-surgical and surgical treatment, whereas other reports claim success rates of 40% to 70% for self-improvement without treatment. Therefore, the purpose of this study was to (1 identify systematic reviews comparing temporomandibular joint disorder surgical and non-surgical treatment, (2 evaluate their methodological quality, and (3 evaluate the evidence grade within the systematic reviews. Methods A search strategy was developed and implemented for MEDLINE, Cochrane Library, LILACS, and Brazilian Dentistry Bibliography databases. Inclusion criteria were: systematic reviews (± meta-analysis comparing surgical and non-surgical TMJD treatment, published in English, Spanish, Portuguese, Italian, or German between the years 1966 and 2007(up to July. Exclusion criteria were: in vitro or animal studies; narrative reviews or editorials or editorial letters; and articles published in other languages. Two investigators independently selected and evaluated systematic reviews. Three different instruments (AMSTAR, OQAQ and CASP were used to evaluate methodological quality, and the results averaged. The GRADE instrument was used to evaluate the evidence grade within the reviews. Results The search strategy identified 211 reports; of which 2 were systematic reviews meeting inclusion criteria. The first review met 23.5 ± 6.0% and the second met 77.5 ± 12.8% of the methodological quality criteria (mean ± sd. In these systematic reviews between 9 and 15% of the trials were graded as high quality, and 2 and 8% of the total number of patients were involved in these studies. Conclusion The results indicate that in spite of the widespread impact of TMJD, and the multitude of

    To determine abnormalities of the temporomandibular joint (TMJ) associated with cervical extension-flexion injury (whiplash) with use of MR imaging. Sixteen patients (32 joints) with TMJ syndrome-related symptoms after whiplash injuries from automobile accidents were evaluated by MR imaging. None of the patients had direct trauma to the jaw, mouth, or face. T1-weighted closed- and opened-mouth views were obtained in the sagittal plane, and closed-mouth views were obtained in the coronal plane. T2-weighted closed-mouth views obtained in the sagittal plane were also obtained to optimize identification of fluid/edema. Fourteen (87%) of 16 patients had one or more of the following TMJ abnormalities: 11 (34%) had anterior displacement of the disk with reduction and 2 (6%) had anterior displacement of the disk without reduction. On T2-weighted images, 17 TMJs (53%) had joint fluid and 5 (16%) had fluid localized to the capsule and/or pterygoid muscle. These data demonstrated a high incidence of TMJ abnormalities related to whiplash injury. The predominant finding was associated fluid/edema, suggesting that T2-weighted images are particularly useful for the evaluation of patients who present with whiplash injury

    Full Text Available This paper describes a case of a young patient who sought help because of pain in the right temporomandibular joint (TMJ. She also reported increasing of pain during chewing. Clinical examination revealed limited mouth opening with uncorrected deviation to the ipsilateral side. Palpation of the lateral pole of the right condyle discovered crepitus, and maximum assisted opening elicited a report of “familiar pain”. The diagnosis of osteoarthritis of the TMJ (RDC / TMD criteria, Axis I, Group III was confirmed by CBCT of TMJ. There is no “gold standard” for the management of TMD, but the need for TMD treatment has to be based on precise indications related to the presence of pain, limitation in function of the lower jaw and signs of degenerative joint disease. Conservative, reversible therapeutic procedures are considered as the first choice for TMD treatment and their task is to improve the function of the entire masticatory system. In this case patient was treated with the combination of physical therapy and stabilization splint, in order to reduce the pain and restore the normal function of the lower jaw. At 6 months’ follow-up symptoms have almost completely disappeared, while 3 years later, the patient still has no significant subjective symptoms. In the present case non-invasive therapy was sufficient to bring, otherwise recurrent nature of osteoarthritis, in complete remission and keep it like that for years.

    Maxillofacial trauma in cats often results in mandibular symphyseal separation in addition to injuries of the caudal mandible and/or temporomandibular joint (TMJ). Caudal mandibular and TMJ injuries are difficult to access and stabilize using direct fixation techniques, thus indirect fixation is commonly employed. The immediate goals of fixation include stabilization for return to normal occlusion and function with the long-term objective of bony union. Indirect fixation techniques commonly used for stabilization of caudal mandibular and temporomandibular joint fracture/luxation include maxillomandibular fixation (MMF) with acrylic composite, interarcade wiring, tape muzzles, and the bignathic encircling and retaining device (BEARD) technique. This article introduces a modification of the previously described "labial reverse suture through buttons" technique used by Koestlin et al and the "labial locking with buttons" technique by Rocha et al. In cases with minimally displaced subcondylar and pericondylar fractures without joint involvement, the labial button technique can provide sufficient stabilization for healing. Advantages of the modified labial button technique include ease of application, noninvasive nature, and use of readily available materials. The construct can remain in place for a variable of amount of time, depending on its intended purpose. It serves as an alternative to the tape muzzle, which is rarely tolerated by cats. This technique can be easily used in conjunction with other maxillomandibular repairs, such as cerclage wire fixation of mandibular symphyseal separation. The purpose of this article is to demonstrate a modified labial button technique for maintaining occlusion of feline caudal mandibular fractures/TMJ luxations in a step-by-step fashion.

    The aim of this study was to investigate the effect of the autologous blood injection (ABI) for chronic recurrent temporomandibular joint (TMJ) dislocation using magnetic resonance imaging (MRI). ABI was applied to 14 patients who had chronic recurrent TMJ dislocation. MRIs of the patients were taken and compared before and one month after the injection. All of the patients had no dislocations of their TMJs on clinical examination one month after the injection. In the pre-injection, unilateral or bilateral TMJ dislocations were observed on MRIs in all patients. One month after the injection, TMJ dislocations were not observed in MRI evaluation of any patients. A significant structural change that caused by ABI was not observed. The procedure was easy to perform and it caused no foreign body reaction. However, it was unclear how the procedure prevented the dislocation.

    Laterality of function in the orofacial musculature suggests there may be side-to-side asymmetry of proprioceptive acuity in lip movement compared to the temporomandibular joint (TMJ). In the present work, 14 young adults were tested for acuity of lip and TMJ closure movements onto plugs varying from 5 to 8mm without visual feedback. Testing was conducted on both left and right sides, using the same psychophysical task and stimuli. Results showed superior proprioceptive acuity at the lips, with no significant side effect. However, there was side-to-side asymmetry in the correlations between proprioceptive performance for the two anatomical structures, with performance on the right side strongly correlated but not on the left. This is consistent with the need for coordination between structures during chewing. When acuity at different points in the stimulus range was examined, the right side lips were better with small stimuli. Overall, results support enhanced use-specific proprioception.

    The influence of circulating serotonin (5-HT) on the effects of intra-articular administration of granisetron on temporomandibular joint (TMJ) pain was investigated in 11 patients with chronic polyarthritides. An analgesic effect superior to placebo has been shown previously. The change in TMJ movement pain intensity was negatively correlated to circulating 5-HT; that is, the higher the 5-HT before injection, the greater the reduction of pain intensity. The resting pain intensity reduction was not related to 5-HT. In conclusion, this study indicates a stronger short-term analgesic effect on TMJ movement pain by intra-articular administration of the 5-HT3 receptor antagonist granisetron in patients with high levels of circulating 5-HT.

    This study aims at analysing the stresses distribution in the temporomandibular joint (TMJ) using a complete high-resolution finite element model (FE Model). This model is used here to analyse the stresses distribution in the discs during a closing jaw cycle. In the end, this model enables the prediction of the stress evolution in the TMJ disc submitted to various loadings induced by mandibular trauma, surgery or parafunction. The geometric data for the model were obtained from MRI and CT scans images of a healthy male patient. Surface and volume meshes were successively obtained using a 3D image segmentation software (AMIRA(®)). Bone components of skull and mandible, both of joint discs, temporomandibular capsules and ligaments and dental arches were meshed as separate bodies. The volume meshes were transferred to the FE analysis software (FORGE(®)). Material properties were assigned for each region. Boundary conditions for closing jaw simulations were represented by different load directions of jaws muscles. The von Mises stresses distribution in both joint discs during closing conditions was analyzed. The pattern of von Mises stresses in the TMJ discs is non-symmetric and changed continuously during jaw movement. Maximal stress is reached on the surface disc in areas in contact with others bodies. The three-dimension finite element model of masticatory system will make it possible to simulate different conditions that appear to be important in the cascade of events leading to joint damage.

    The aim of this study was to assess the electromyographic characteristics of the masticatory muscles (masseter and temporalis) of patients with either "temporomandibular joint disorder" or "neck pain". Surface electromyography of the right and left masseter and temporalis muscles was performed during maximum teeth clenching in 38 patients aged 21-67 years who had either (a) temporomandibular joint disorder (24 patients); (b) "neck pain" (13 patients). Ninety-five control, healthy subjects were also examined. During clenching, standardized total muscle activities (electromyographic potentials over time) were significantly different in the three groups: 75 microV/microVs% in the temporomandibular joint disorder patients, 124 microV/microVs% in the neck pain patients, and 95 microV/microVs% in the control subjects (analysis of variance, Ptemporomandibular joint disorder patients also had significantly (Pneck pain patients (87%) or control subjects (92%). A linear discriminant function analysis allowed a significant separation between the two patient groups, with a single patient error of 18.2%. Surface electromyographic analysis during clenching allowed to differentiate between patients with a temporomandibular joint disorder and patients with a neck pain problem.

    Full Text Available The central importance of BMP signaling in the development and homeostasis of synovial joint of appendicular skeleton has been well documented, but its role in the development of temporomandibular joint (TMJ, also classified as a synovial joint, remains completely unknown. In this study, we investigated the function of BMPRIA mediated signaling in TMJ development in mice by transgenic loss-of- and gain-of-function approaches. We found that BMPRIA is expressed in the cranial neural crest (CNC-derived developing condyle and glenoid fossa, major components of TMJ, as well as the interzone mesenchymal cells. Wnt1-Cre mediated tissue specific inactivation of BmprIa in CNC lineage led to defective TMJ development, including failure of articular disc separation from a hypoplastic condyle, persistence of interzone cells, and failed formation of a functional fibrocartilage layer on the articular surface of the glenoid fossa and condyle, which could be at least partially attributed to the down-regulation of Ihh in the developing condyle and inhibition of apoptosis in the interzone. On the other hand, augmented BMPRIA signaling by Wnt1-Cre driven expression of a constitutively active form of BmprIa (caBmprIa inhibited osteogenesis of the glenoid fossa and converted the condylar primordium from secondary cartilage to primary cartilage associated with ectopic activation of Smad-dependent pathway but inhibition of JNK pathway, leading to TMJ agenesis. Our results present unambiguous evidence for an essential role of finely tuned BMPRIA mediated signaling in TMJ development.

    When occurring in childhood, temporomandibular ankylosis joint is responsible for complex maxillofacial deformities, including mandibular growth deficiency. We present a case of temporomandibular joint ankylosis associated with severe mandibular asymmetry treated by mandibular bone distraction performed under computer assistance. A 27-year-old patient presented with a severe facial asymmetry consisting in hypoplasia of the left hemi-mandible and maxilla. Mouth opening was non-existent. The CT-scan showed a left temporomandibular ankylosis. A left mandibular distraction was decided. The distraction characteristics (choice and positioning of the distractor, axis and amount of distraction) were determined preoperatively on the 3D CT-scan. The planning has been transferred to a navigation console (Kolibri®, Brainlab®). A combined intraoral and cutaneous was performed. Navigation allowed for an appropriate placement of the osteotomy line and fixation of the distractor. Distraction was started at the 5th postoperative day at the rate of 1mm per day and lasted 25 days without complication. 3D planning allows for better indication setting, better preparation of the procedure, reducing complications and operative time. It may help as an educational tool for young surgeons and for a better understanding from the patient. Navigation is an accurate method for the transfer of the planning in the operation room.

    Temporomandibular joint (TMJ) is a synovial joint that represents the junction of mandible with skull. TMJ and mastication muscles are affected by temporomandibular disorders (TMDs). During the last two decades the advances in imaging diagnostic of TMJ have greatly contributed to the assessment of the TMJ disorders. Labelled leukocytes with technetium- 99m hexamethyl propylene amine oxime ( 99m Tc-HMPAO) represent an efficient method that generates images based in physiological and/or biochemical changes related to inflammation. The aim of this study was to investigate the potential usefulness of technetium-99m labelled leukocytes scintigraphy in the diagnosis of TMJ inflammatory process applying a rabbit TMJ arthritis model. Arthritis was induced unilaterally with an intra-articular injection of ovalbumin in left ATM. On the contra-lateral side, the same dose of saline was injected. After five days, leukocytes were labeled with HMPAO and 99m Tc-HMPAO TMJ scintigraphic images were made. After twelve days a computed tomography was realized. Scintigraphic images obtained five days after induction of TMJ inflammation showed the localization of inflammatory process. The results were expressed as cpm of activity found in left ATM and contra-lateral side. Significant differences of activity were found between inflamed articulation and contra-lateral side (P = 0,0073). In conclusion, the method of leukocytes labeled with 99m Tc showed to be sensitive in detection of inflammatory disorders of TMJ and can be of great value in early diagnostic of these disorders.

Osseous changes of the TMJ were evaluated in forty-three patients. Osseous changes of the condylar head and articular eminence were observed in 41 joints and 64 joints, respectively on transcranial radiographs, and 48 joints and 59 joints, respectively on MRI. The flattening, sclerosis, erosion, and osteophyte formation of the condylar heads were observed in 36.6%, 43.9%, 12.2%, and 7.3%, respectively on transcranial radiographs compared with 35.4%, 20.8%, 37.5%, and 6.3%, respectively on MRI. While, the flattening, sclerosis, and erosion of the articular eminences were observed in 26.6%, 67.2%, and 6.2%, respectively on transcranial radiographs compared with 32.2%, 59.3%, and 8.5%, respectively on MRI. There were no statistical differences between transcranial radiographs and MRI scans in the detection of osseous changes of the TMJ. However, MRI scans were superior to the transcranial radiographs in the detection of erosion of the condylar head (p<0.01).

    Temporomandibular disorders (TMD) refer to a group of clinical picture affecting the masticatory muscles and temporomandibular joint that are characterized by muscular or joint pain, dysfunction (limited or altered functions) and joint noises, as well as other associated symptoms, such as tension headaches, otalgia, dizziness, tinnitus, and others. Fibromyalgia (FM) is a syndrome of unknown etiology involving generalized chronic pain accompanied, in a high percentage of cases, by other symptoms such as asthenia, anxiety, depression, sleep disturbances, and other less frequent symptoms, such as temporomandibular disorders (TMD). Data were compiled by two experienced examiners following a specific form. An electronic search was carried out in the Cochrane Central Register of Controlled Trials (CENTRAL), PUBMED, and SCOPUS electronic databases (up to April 2016, unrestricted by date or language). Comparative clinical studies with patients with both clinical pictures involving the study of pathogenic processes. Fibromyalgia and temporomandibular disorders with muscle pain both have profiles that affect the muscular system and therefore share many epidemiological, clinical, and physiopathological symptoms. Because of this, we are led to think that there is, if not a common etiology, at least a common pathogenesis. This article revises the physiopathological processes of both clinical pictures in an attempt to determine their similarities and likenesses. This would undoubtedly help in providing a better therapeutic approach.

    To report the number and frequency of incidental findings (IFs) detected during magnetic resonance (MR) imaging screening of the temporomandibular joint (TMJ) and to define related diseases. Bilateral TMJ MR images in the sagittal and coronal sections, from 518 patients with TMJ symptoms were evaluated retrospectively. Patients who were diagnosed with IFs were sent for consultation and clarification of the findings. Patient age, gender, IFs, locations, and diseases were classified and noted.  Results: Seventy-eight (15%) patients were diagnosed with 117 IFs. Of them, 43 were diagnosed with a single IF, and 35 were diagnosed with more than one IF. The most frequent locations were paranasal sinuses and mastoid air cells. The most frequent diseases were inflammatory and cystic lesions.  Discussion: While examining TMJ MR images, it is important to check for evidence of IFs or pathologies that may have mimicked signs and symptoms of TMJ disorders.

    In the last decade, the equine masticatory apparatus has received much attention. Numerous studies have emphasized the importance of the temporomandibular joint (TMJ) in the functional process of mastication. However, ultrastructural and histological data providing a basis for biomechanical and histopathological considerations are not available. The aim of the present study was to analyze the architecture of the collagen fiber apparatus in the articular surfaces of the equine TMJ to reveal typical morphological features indicating biomechanical adaptions. Therefore, the collagen fiber alignment was visualized using the split-line technique in 16 adult warmblood horses without any history of TMJ disorders. Within the central two-thirds of the articular surfaces of the articular tubercle, the articular disc and the mandibular head, split-lines ran in a correspondent rostrocaudal direction. In the lateral and medial aspects of these articular surfaces, the split-line pattern varied, displaying curved arrangements in the articular disc and punctual split-lines in the bony components. Mediolateral orientated split-lines were found in the rostral and caudal border of the articular disc and in the mandibular fossa. The complex movements during the equine chewing cycle are likely assigned to different areas of the TMJ. The split-line pattern of the equine TMJ is indicative of a relative movement of the joint components in a preferential rostrocaudal direction which is consigned to the central aspects of the TMJ. The lateral and medial aspects of the articular surfaces provide split-line patterns that indicate movements particularly around a dorsoventral axis. Copyright © 2016 Elsevier Ltd.

    A descriptive, comparative and prospective study of 132 patients with disorders of the temporomandibular joint, classified according to the degree of severity, who attended the specialized department of the Provincial Teaching Dental Clinic from Santiago de Cuba was carried out from March, 2009 to September, 2010, in order to determine the benefits obtained with the ultrasonic therapy in the sick persons. In the series, the most affected were: the female sex, the age group 40-49, and the severe cases were few in number, while the mild and moderate disorders had similar proportions. When applying the ultrasonic and conventional therapies, the group that received treatment with the first one was that with a satisfactory clinical course.

    Orthodontists are fully prepared to treat the problems of occlusion that they are called upon to deal with every day. On the other hand temporo-mandibular joint disorders present more obscure difficulties from the point of view of detection and diagnosis as well the management of their treatment. That is why a profound understanding of the anatomical and physiological functioning of the temporo-mandibular joint has become indispensable for today's orthodontists who are now asked to detect and diagnose an assortment of TMJ disturbances whose etiology may vary greatly. By performing a rigorous diagnostic procedure, based on a thorough clinical examination supported by careful axiographic and radiological studies, of temporo-mandibular malfunctioning and its underlying etiological causes, which are primarily dento-alveolar and occlusal in nature, orthodontists will be able to adopt an appropriate therapeutic approach that might be purely orthodontic or multi-disciplinary and carried out with the collaboration of specialists in occlusion, oral surgery, and even osteopathy.

    Full Text Available Synovial inflammation (synovitis frequently accompanies intracapsular pathologic conditions of the temporomandibular joint (TMJ such as internal derangement (ID and/or osteoarthritis (OA, and is suggested to be associated with symptom severity. To identify the putative factors associated with synovitis, we investigated interleukin (IL-1β- and/or tumor necrosis factor (TNF-α-responsive genes of fibroblast-like synoviocytes (FLS from patients with ID and/or OA of TMJ using microarray analysis. In this review, we first summarize the FLS of TMJ and the signaling pathways of IL-1β and TNF-α. Next, we show the up-regulated genes in FLS after stimulation with IL-1β or TNF-α, and summarize the gene functions based on recent studies. Among the top 10 up-regulated factors, molecules such as IL-6 and cycrooxygense-2 have been well characterized and investigated in the inflammatory responses and tissue destruction associated with joint diseases such as RA and OA, but the roles of some molecules remain unclear. The FLS reaction can lead to the synthesis and release of a wide variety of inflammatory mediators. Some of these mediators are detected in joint tissues and synovial fluids under intracapsular pathologic conditions, and may represent potential targets for therapeutic interventions in ID and/or OA of TMJ.

    Magnetic Resonance Images (MRI) of the temporomandibular joint (TMJ) are usually performed to study the opening/closing movements of the mandible and have up to now been pseudodynamic step-by-step images simulating condylar motion by post-processing reconstruction. The aim of this study was: 1. to optimize a TMJ cine-imaging method to give a better clinical result than the step-by-step methods; 2. to develop an ultra-fast MRI Gradient Echo (GE) sequence for this purpose; and 3. to analyze condylar movements in the sagittal, coronal and para-axial planes during border mandibular displacements and chewing. Both TM joints were studied in six asymptomatic volunteers. The method involved a compromise between in-plane resolution, slice thickness, signal-to-noise ratio and time resolution. Routine clinical use was found to be a GE pulse sequence providing three images per second with an isometric voxel resolution of approximately two millimeters in ridge. This did not allow visualization of the disk. Using this sequence enabled real and simultaneous condylar displacement observation in the three planes of space and therefore contributed to a better functional diagnosis of pathologic TMJ motions.

    2017-01-01

    This study reviewed the dental literature in order to determine the association of bone marrow edema with osteoarthritis and temporomandibular joint (TMJ) internal derangement disorders. A literature search was performed using electronic databases PubMed/Medline (National Library of Medicine, Bethesda, Maryland) and Cochrane for articles published during the last 15 years (January 2000-December 2014). A predetermined inclusion and exclusion criteria were used for filtering the scientific papers. Research articles fulfilling the basic inclusion criteria were included in the review. The reviewed studies showed that bone marrow edema is found in painful joints with osteoarthritis in a majority of cases. A few cases with no pain or significant degenerative changes are reported to have a bone marrow edema pattern as well. Bone marrow edema, increased fluid level, and pain are associated with osteoarthritis in the majority of patients reporting TMJ arthritis. Degenerative and disc displacement conditions are multifactorial and require further investigations. Magnetic resonance imaging can be employed to detect bone marrow edema even in the absence of pain and clinical symptoms in the patients of internal derangements.

    The aim of this study was to assess the influence of protraction facemask (PFM) on temporomandibular joint (TMJ) of skeletal Class III malocclusion patients. Literature searches were carried out electronically in five English and three Chinese databases (Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, PubMed, Embase, MEDLINE (via Ovid), Chinese Biomedical Literature Database, China National Knowledge Infrastructure, and VIP Database). The date of the most recent search was 22 March 2017. Randomized controlled trials, controlled clinical trials, cohort studies, and before-after studies comparing the effect of PFM and other treatments on TMJ were included. The data were collected and extracted by three authors. The risk of bias in the RCTs was assessed in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. For the nonrandomized studies, the risk of bias was judged with Newcastle-Ottawa Scale. For the 261 articles identified, 13 studies with 522 participants were included for the final qualitative analysis. Three studies were graded as high value of evidence, while seven studies and the other three studies were graded as moderate value and low value respectively. According to the available evidence, PFM contributed to the significant increase of CondAx-SBL and the significant decrease of CondAx-ML. Thin-plate spline (TPS) analysis showed a horizontal compression in condyles. Condyles tended to move superiorly and posteriorly. Concerning the occurrence of temporomandibular disorders (TMD), PFM was not involved in aggravating TMJ symptoms and signs. Clinical evidence suggests that PFM might contribute to the morphologic adaptation of TMJs and displacement of condyles, and PFM may well be not a risk factor for the development of TMD.

    Temporomandibular disorders (TMD) consist of a group of pathologies that affect the masticatory muscles, temporomandibular joints (TMJ), and/or related structures. String instrumentalists, like many orchestra musicians, can spend hours with head postures that may influence the biomechanical behavior of the TMJ and the muscles of the craniocervicomandibular complex (CCMC). The adoption of abnormal postures acquired during performance by musicians can lead to muscular hyperactivity of the head and cervical muscles, with the possible appearance of TMD. Medical infrared thermography is a non-invasive procedure that can monitor the changes in the superficial tissue related to blood circulation and may serve as a complement to the clinical examination. The objective of this study was to use infrared thermography to evaluate, in one subject, the cutaneous thermal changes adjacent to the CCMC that occur before, during, and after playing a string instrument.

    2007-12-01

    Pathologies currently defined as temporomandibular disorders may be different in nature. Temporomandibular joint (TMJ) disorders and craniofacial and cervical myogenous pain (MP) are distinct pathologies but may be superimposed and share some etiologic factors. Tension-type headache (TTH) may often be associated with craniofacial and cervical pain, and the same pharmacologic and nonpharmacologic treatment may be efficacious for both. Psychiatric comorbidity (depression and/or anxiety disorder) is less frequent in sheer TMJ disorders, compared with MP and TTH. A screening for the presence of an underlying psychiatric disorder should be part of the clinical evaluation in patients suffering from headache and facial pain.

    2015-06-01

    This article reviews the pathophysiology of scleroderma (systemic sclerosis [SSc]) and its destructive effects on the mandible in general and the temporomandibular joint (TMJ) in particular. It discusses the considerations of operating on patients with devastating chronic disease and presents 2 cases of TMJ reconstruction in patients with the diagnosis. Two patients with different degrees of SSc involvement underwent TMJ reconstruction with costochondral grafts. The patients represent the surgical considerations pertinent to this disease and different outcomes as determined by the variance in severity of their afflictions. The 2 patients tolerated the surgeries well and exhibited improvement in function in the long-term. One patient thrives and continues to do well despite her SSc approximately 10 years postoperatively; the second patient died of her disease approximately 9 years after her initial surgical care. The experience with these 2 cases showed that patients with SSc can safely undergo TMJ reconstruction with anticipated good results, but that the overall severity of the disease remains paramount in determining the feasibility of corrective surgery under this diagnosis.

    In the present study, we investigated whether bone changes are present in sites impossible to observe by panoramic X-ray and Schuller's X-ray examination, namely the medial of the condylar head and mandibular fossa, in patients with type IV temporomandibular joint disorders. We observed the articular fossa using computed tomography, which is able to obtain detailed 3-dimensional information, in patients with type IV temporomandibular disorders. We examined 120 joints of 60 patiens who visited the Department of Oral Surgery, Osaka Medical College Hospital. Each condylar head was clearly visualized in panoramic X-ray and Schuller's X-ray examination findings, and shown to have possible changes unilaterally. Each joint was diagnosed as type IV, according to the diagnostic guidelines set by Japanese Society for Temporomandibular Joint, and further examined using helical CT. Changes in condylar head; We concluded that bone changes were present with considerable probability in the medial of condylar head in a manner similar to those found in the lateral and center of joints with type IV temporomandibular disorders. Changes in mandibular fossa; The bone changes occurred in various locations of the mandibular fossa, while they appeared significantly more frequently in the condylar head. We think that our finding will contribute to development of treatment strategies for temporomandibular disorders, as they clarify bone changes in sites previously unreported. (author)

    .PURPOSE: to submit an oral miofunctional therapeutic proposal, the procedures used in cases of bilateral ankylosis of the temporomandibular and the results, joint standing out the importance of interdisciplinary work and the oral miofunctional therapy contribution to rehabilitation of the stomatognatic system in these cases. METHODS: this case report is about an adult, male, referred to evaluation and specific procedures three months after the joint surgery. Core complaint was great restriction of mouth opening range. The oral miofuncional exam assessment has shown: mouth opening of 25 mm, lack of laterality and protrusion movements, previous open bite of 8 mm, difficulty in chewing, swallowing, speech articulation and pain in temporal muscles. The therapeutical objectives were: stimulate and allow the execution of mandible movements, preventing restrictive cicatricial tissue and functional rehabilitation. Procedures related to increasing the amplitude through looseness, stretching, massages, and specific maneuvers as distraction and lever had been essential to stabilize the opening of the mouth, to liberate the mandible movements partially and to co-ordinate them as long as it improves the functionality of the stomatognatic system. RESULTS: after 24 sessions were: gain of 16 mm in the opening, passing to 41 mm with stability according to annual control; reduction of the previous bite open for 4 mm; improvement in the hygienic cleaning, in the speech articulation, in the alimentary conditions with acquisition of chewing strength and reduction of the compensatory mechanisms; elimination of pain in the region of the temporal muscles in addition to improvement in the facial esthetics. CONCLUSION: the oral miofunctional therapeutic reveals itself efficient in adult with bilateral ankylosis of the temporomandibular joint, after surgical procedure, with stability of results maintained according to annual control.

    Ankylosis of the temporomandibular joint in children is one the most difficult and complex conditions managed by oral and maxillofacial surgeons, and often leads to some facial deformity. Distraction osteogenesis of the mandible provides an excellent treatment for mandibular airway obstruction in children who do not respond to conservative measures, and allows for early removal of the tracheostomy. We report the case of a 1-year-old boy with severe micrognathia and temporomandibular ankylosis who was dependent on a tracheostomy; he was treated with piezosurgery and mandibular advancement by distraction osteogenesis.

    Aim: To compare clinical feasibility of static two-dimensional (2D) to three-dimensional (3D) sonography of the temporomandibular joint (TMJ) in assessment of disk dislocation and joint degeneration compared to magnetic resonance imaging (MRI). Method: Thirty-three patients, 66 TMJ were prospectively sonographed 2D and 3D (8-12.5 MHz step motor scan), in occlusion and maximum opening with a probe position parallel inferior to the zygomatic arch. Axial 2D images were judged independent from the 3D scans; 3D volumes were cut axial, sagittal, frontal and rotated in real-time. Disk position and joint degeneration were assessed and compared to a subsequent MRI examination. Results: The specific appearance of the disk was hypoechogenic overlying a hyperechogenic condyle in axial (2D) or sagittal and frontal (3D) viewing. Specificity of 2D sonography for disk dislocation was 63%, sensitivity 58%, accuracy 64%, positive predictive value 46%, negative predictive value 73%; for joint degeneration synonymously 59/68/61/38/83%. 3D sonography for disk displacement reached synonymously 68/60/69/51/76%, for joint degeneration 75/65/73/48/86%. 2D sonographic diagnoses of disk dislocation in the closed mouth position and of joint degeneration showed significantly different results from the expected values (MRI) in {chi} {sup 2} testing; 3D diagnoses of disk dislocation in closed mouth position, of joint degeneration, 2D and 3D diagnoses in open mouth position were nonsignificant. Conclusions: Acceptable was the overall negative predictive value, as specificity and accuracy for joint degeneration in 3D. 3D appears superior diagnosing disk dislocation in closed mouth position as for overall joint degeneration. Sensitivity, accuracy and positive predictive value will have to ameliorate with future equipment of higher resolution in real-time 2D and 3D, if sonographic screening shall be clinically applied prior to MRI.

    Patients with orofacial pains are generally treated by physicians. A small number of patients are treated for pain in the temporomandibular joint, the masticatory and the neck muscles, by dentists and orofacial surgeons. Among half of the patients being treated in neurological headache clinics, the temporomandibular joint and the masticatory muscles are the source of the pain. In order to achieve better research and a classification, the International Headache Society, consisting largely of neurologists, developed a classification system. A comparable development occurred among oral health specialists. Employing these 2 methods with the same patients leads to different diagnoses and treatments. Both the International Classification of Headache Disorders II and the Research Diagnostic Criteria for Temporomandibular Disorders are being revised. This creates the opportunity to establish a single classification for these orofacial pains, preferably within the new International Classification of Headache Disorders.

    Temporomandibular disorder (TMD) is still not defined with respect to the point of an entity, terminological problems, and clinical classification and gradings. Moreover, diagnostic problems of internal deranegement and osteodeformity at the temporomandibular joint such as type IV and mechanism of bone remodeling at condylar head are also still not clear. In this investigation, we tried to classify the severity and progressive grading according to the symptoms and objective laboratory data taken from soft tissues such as muscles related to mastication, discs and ligaments, and hard tissues such as condylar head and temporal bone changes around the temporomandibular joint. Preliminary diagnostic clinical tool of the assessment of temporomandibular joint by maens of bone scintigraphy was attributed to the additional diagnostic procedure and research for the bone remodeling for the temporomandibular disorder because this can be defined between subjective and objective symptoms in this disorder. Bone scintigraphy will solve many problems concerning undefined degenerative bone changes in TMD, enable more accurate diagnosis, and the selection of treatment and prognosis in future investigation. Also, it is believed single photon emission computed tomography (SPECT) nuclear bone imaging is a highly accurate diagnostic method for craniomandibular disorders. (author)

  5. The role of molecular pain biomarkers in temporomandibular joint internal derangement.

    Ernberg, M

    2017-06-01

    There is evidence that low-grade inflammation may be responsible for pain and development of degenerative changes in temporomandibular joint internal derangement. This article reviews the current knowledge of the molecular mechanisms behind TMJ internal derangements. A non-systematic search was carried out in PubMed, Embase and the Cochrane library for studies regarding pathophysiological mechanisms behind internal derangements focusing on pain-mediating inflammatory and cartilage-degrading molecules. Recent data suggest that release of cytokines may be the key event for pain and cartilage destruction in TMJ internal derangements. Cytokines promote the release of matrix metalloproteinases (MMPs), and due to hypoxia, vascular endothelial growth factor (VEGF) is released. This activates chondrocytes to produce MMPs and reduce their tissue inhibitors (TIMPs) as well as the recruitment of osteoclasts, ultimately leading to cartilage and bone resorption. Also, proteoglycans have an important role in this process. Several cytokines, MMPs, TIMPs and VEGF have been identified in higher concentrations in the TMJ synovial fluid of patients with painful internal derangements and shown to be associated with the degree of degeneration. Other molecules that show elevated levels include hyaluronic acid synthase, disintegrin and metalloproteinase with thrombospondin motifs (ADAMTs), aggrecan, fibromodulin, biglycan and lumican. Taken together, more or less pronounced inflammation of TMJ structures with release of cytokines, MMPs and other molecular markers that interact in a complex manner may be responsible for tissue degeneration in internal derangements. As internal derangements may be symptom-free, the degree of inflammation, but also other mechanisms, may be important for pain development. © 2017 John Wiley & Sons Ltd.

    OBJECTIVES: The temporomandibular joints (TMJs) are frequently affected in children with juvenile idiopathic arthritis (JIA). Early detection is challenging, as major variation is present in scoring TMJ pathology on Magnetic Resonance Imaging (MRI). Consensus-driven development and validation...... of a MRI scoring system for TMJs has important clinical utility in timely improvement of diagnosis, and serving as an outcome measure. We report on a multi-institutional collaboration towards developing a TMJ MRI scoring system for JIA. METHODS: Seven readers independently assessed MRI scans from 21...... preferable for assessing minor joint changes over time. Eight items were considered sufficiently reliable and/or important for integration into the consensus scoring system: bone marrow edema and enhancement (avICC=0.57-0.61; %SDD=±45-63% prior to re-defining), condylar flattening (0.95-0.96; ±23...

    The Ehlers-Danlos syndrome, hypermobility type (EDS-HT) is a rare genetic disease. Diagnosis is based on a combination of clinical criteria described in the classification of Villefranche. Diagnosis is difficult to make because of the lack of specific clinical signs and the absence of genetic testing. The EDS-TH manifests itself manly by musculoskeletal pain and joint hypermobility. Temporomandibular disorders (TMD) are also reported. Our aim was to objectify the presence and to qualify the type of TMD associated with the EDS-HT in order to propose an additional diagnostic argument. A prospective, monocenter case-control study, comparing a cohort of patients suffering from EDS-HT to a paired control group of healthy volunteers has been conducted. Clinical examination was standardized, including a general questioning, an oral examination and a temporomandibular joint examination following the TMD/RDC (temporomandibular disorders/research diagnostic criteria). Fourteen EDS-HT patients and 58 control patients were examined. The prevalence of TMDs (n=13; 92.9% vs. n=4; 6.9%; P=10(-11)) was significantly higher in the EDS-HT group. TMDs occurring in the EDS-HT group were complex, combining several mechanisms in contrast to the control group, where only one mechanism was found in all the patients (n=13; 92.9% vs. n=0; 0.0%). TMDs are strongly associated with RDS-HT. TMDs could therefore be used in the diagnosis of this disease. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Numerous procedures have been described for the treatment of chronic recurrent dislocation of the temporo-mandibular joint (TMJ), either in the form of enhancement or restriction of the condylar movement, with their obvious merits and demerits. We present a new technique of using U shaped iliac bone graft to restrict the condylar movement and its advantages over the conventional techniques.We have used this technique successfully in 8 cases where Dautrey's procedure had failed with follow up period of 2 years. No patient complained of recurrent dislocation postoperatively. This a very simple and effective technique where other procedures have failed.

    Full Text Available Herein we report treatment for a 19-year-old female patient with severe osteoarthritis of the temporomandibular joint. The patient had severe open bite with a Class II molar relationship. She had limited mouth opening and pain. Clinical examination and magnetic resonance imaging revealed that she had anterior disc displacement without reduction. By splint therapy, limited mouth opening and pain was eliminated, but an anterior open bite developed after the treatment. By orthodontic treatment, an acceptable occlusion was achieved with a Class I molar relationship.

    The aim of this article was to review the literature about temporomandibular disorders and bruxism and their relationships in children and adolescents. The literature was searched using Medline, ISI, Cochrane Library, Scielo and the Internet, from March 1970 to the end of June 2007. The inclusion criteria were: they evaluated a possible association between TMD and bruxism, and they dealt with child and/or adolescent samples. Furthermore, interim reports, related Internet sites and chapters in textbooks were considered. From 64 records found, 30 fulfilled the inclusion criteria. The prevalence of temporomandibular disorders in children and adolescent varies widely in the literature. Temporomandibular disorders are often defined on the basis of signs and symptoms, of which the most common are: temporomandibular joint sounds, impaired movement of the mandible, limitation in mouth opening, preauricular pain, facial pain, headaches and jaw tenderness on function, having mainly a mild character, fluctuation and progression to severe pain and dysfunction is rare. One of the possible causal factors suggested that temporomandibular disorders in children is a functional mandibular overload variable, mainly bruxism. Bruxism, defined as the habitual nonfunctional forceful contact between occlusal tooth surfaces, is involuntary, excessive grinding, clenching or rubbing of teeth during nonfunctional movements of the masticatory system. Its etiology is still controversial but the multifactorial cause has been attributed, including pathophysiologic, psychologic and morphologic factors. Moreover, in younger children, bruxism may be a consequence of the masticatory neuromuscular system immaturity. Complications include dental attrition, headaches, temporomandibular disorders and masticatory muscle soreness. Some studies have linked oral parafunctional habits to disturbances and diseases of the temporomandibular joint, mainly bruxism, suggesting its association with temporomandibular

    Objective: To analyze related factors on the number of mesenchymal stem cells in the synovial fluid of the temporomandibular joint (TMJ) and provide an research basis for understanding of the source and biological role of mesenchymal stem cells derived from synovial fluid in TMJ. Methods: One hundred and twenty-two synovial fluid samples from 91 temporomandibular disorders (TMD) patients who visited in Department of TMJ Center, Guanghua School of Stomatology, Hospital of Stomatology, Sun Yat-sen University from March 2013 to December 2013 were collected in this study, and 6 TMJ synovial fluid samples from 6 normal volunteers who were studying in the North Campus of Sun Yat-sen University were also collected, so did their clinical information. Then the relation between the number of mesenchymal stem cells derived from synovial fluid and the health status of the joints, age of donor, disc perforation, condylar bony destruction, blood containing and visual analogue scale score of pain were investigated using Mann-Whitney U test and Spearman rank correlation test. Results: The number of mesenchymal stem cells derived from synovial fluid had no significant relation with visual analogue scale score of pain ( r= 0.041, P= 0.672), blood containing ( P= 0.063), condylar bony destruction ( P= 0.371). Linear correlation between the number of mesenchymal stem cells derived from synovial fluid and age of donor was very week ( r= 0.186, P= 0.043). The number of mesenchymal stem cells up-regulated when the joint was in a disease state ( P= 0.001). The disc perforation group had more mesenchymal stem cells in synovial fluid than without disc perforation group ( P= 0.042). Conclusions: The number of mesenchymal stem cells derived from synovial fluid in TMJ has no correlation with peripheral blood circulation and condylar bony destruction, while has close relation with soft tissue structure damage of the joint.

    Introduction: The temporomandibular joint (TMJ) forms the very cornerstone of craniofacial integrity and its ankylosis in a growing child may cause problems in daily food intake, speech, appearance, and oral hygiene is affected to a major extent. It is one of the common acquired pathologies afflicting the skeleton. It is also the most overlooked and under-managed problem in children. Materials and Methods: A house to house survey was conducted between 2010 and 2011 in rural and urban areas of Lucknow. A total of 21,720 children aged between 3-15 years from 9090 houses comprising a representative sample were included. Results: Ten TMJ ankylosis cases were identified in 21,720 children. Of these, six were bilateral and four were unilateral. Male to female ratio was 1:9, with most patients (70.0%) being in the 10-15 years’ age group (mean age was 11.1 years ± 3.34). The most common cause of ankylosis was trauma for 90.0% of cases. The majority of patients (70%) were reporting the condition for the first time, with 30% patients having had previous treatment. Conclusion: TMJ ankylosis is an acquired condition in most of the cases. Birth/childhood trauma would be the major causative factor. Knowledge amongst parents, providers of health about this entity was poor. Initial management of the causative factor was poor. Mere knowledge among the general population and healthcare providers can result in primary prevention and also secondary prevention along with its successful definitive treatment. PMID:23251054

    Full Text Available Temporomandibular disorder (TMD is an inclusive term in which those conditions disturbing the masticatory function are embraced. It has been estimated that 33% of the population have signs of TMD, but less than 5% of the population will require treatment. The objective of this study was to measure the frequency of TMD in rheumatoid arthritis (RA, osteoarthrosis (OA, ankylosing spondylitis (AS and systemic lupus erythematosus, and to define the limitations in everyday’s life that patients perceive when present. A six-month survey of consecutive outpatients in a rheumatology clinic in a teaching hospital in Mexico was carried out. We defined TMD as: 1 the presence of pain; 2 difficulty on mouth opening, chewing or speaking; 3 the presence of non-harmonic movements of the temporomaxilar joints. All three characteristics had to be present. Z test was used to define differences between proportions. We present the results of 171 patients. Overall, 50 patients had TMD according to our operational definition (29.24%. Up to 76% of the sample had symptoms associated with the condition. TMD is more frequent in OA and in AS (29.24% vs 38% OA, P=0.009; 39% AS; P=0.005. We found no association between the severity of TMD and the request for specific attention for the discomfort produced by the condition. Only 8 of 50 (16% patients with TMD had requested medical help for their symptoms, and they were not the most severe cases. TMD is more frequent in RA and OA. Although it may produce severe impairment, patients seem to adapt easily.

    Thirty-nine temporomandibular joints (TMJ) from 20 patients with suspected internal derangements were imaged by a 1.5 T MR imager. The on-resonance binomial magnetization transfer contrast (MTC) pulse was applied to gradient echo images with a dual receiver coil (9 s/section). With the use of an opening device, a series of sequential images were obtained at increments of mouth opening and closing. The tissue signal intensities with (Ms) and without (Mo) MTC were measured and subjective image analysis was performed. Compared with the standard images, MTC technique provided selective signal suppression of disks. The average of Ms/Mo ratio of the disks (0.56) was lower than that of the retrodiskal pad (0.79) and of the effusion (0.89). With MTC technique, fluid conspicuity was superior to standard image. However, no significant superiority was found in disk definition subjectively. (orig.)

    The objective of this study was to describe the arthroscopic findings of chondromalacia and its relation with the internal derangement of the temporomandibular joint (TMJ). A total of 161 patients (299 TMJs) who underwent arthroscopy were included in the study. The TMJs were evaluated objectively under arthroscopic vision, and 4 groups of patients were established according to the degree of involvement, degree I, II, III and IV. Statistical analyses were conducted using logistic regression models (P chondromalacia and 66 (41%) in 88 joints exhibited some degree of chondromalacia (44 patients unilaterally and 22 bilaterally). Of the 88 joints with chondromalacia, 14 (15.9%) had chondromalacia degree I, 12 (13.6%) chondromalacia degree II, 20 (22.7%) chondromalacia degree III and 42 (47.7%) chondromalacia degree IV. The chondromalacia was more significantly found in patients with ADDwR and discal perforation (P Chondromalacia degree IV was a significant finding in cases of ADDwoR (P = 0.000619). Chondromalacia of the TMJ is a common finding in patients with internal derangement even at the early stages. Copyright © 2016 European Association for Cranio-Maxillo-Facial Surgery.

    Background: disorders (TMDs) such as pain, joint sounds, and impaired movement are common, and magnetic resonance imaging (MRI) is now the method of choice for diagnostic assessment. Purpose: To describe MR criteria chosen and the amount of temporomandibular joint (TMJ) pathology registered when examining MR images from patients referred to a university hospital for imaging of their TMJs. Material and Methods: The TMJs of 152 consecutive patients, 102 women and 40 men, referred for MRI during an 18 month period were imaged with a 1.5 T imaging system. Twelve asymptomatic students, seven women and five men, gave informed consent and acted as a control group. Results: Moderate to extensive disk displacement was registered in 53% of the patients' TMJs, and 38% of the disks were deformed. Degenerative changes registered were flattening of the condyle heads in 50% of the TMJs and erosion of their cortical surfaces in 30%. Osteophytes were present in 31% of the condyles and bone marrow edema in 30%. Marked to extensive effusion in synovial compartments was registered in 39% of the studied TMJs. In the control group, none of the TMJs showed anterior disk displacement, deformed disks or degenerative changes, but 8 of the 24 joints showed marked effusion. A tendency for a higher amount of disk displacement and deformation was seen among young age groups and more degenerative changes in older age groups, but differences among groups were not significant when tested with chi-square analysis. Conclusion: Defined MR criteria that allow for comparative assessment are presented. According to these criteria, a large proportion of the patients referred for MR examination showed morphologic changes indicating TMJ pathology. Keywords Disk displacement, arthrosis

    Since publication of the UK guidelines on total replacement of the temporomandibular joint (TMJ) in 2008 by the British Association of Oral and Maxillofacial Surgeons (BAOMS), pain scores, mouth opening, and diet have been used as markers of success. We have looked at quality of life (QoL) as another. We analysed the data from a single surgeon on patients who had had joints replaced and devised a questionnaire to find out about the subjective, functional, psychological, and social aspects of TMJ disease. A total of 18 patients who had the same operation were included (mean (range) age 50 (33 - 73) years, mean (range) follow up 30 (18 - 48) months). Jaw function and facial aesthetics had improved, and patients needed less analgesia. Overall, they reported a better QoL with improvements in mood and social interaction, and the activities of daily life were easier. The NHS uses QoL questionnaires to measure success in fields such as orthopaedic surgery, but currently we know of no nationally accepted questionnaire that measures success after total replacement of the TMJ.

    Full Text Available Purpose. We evaluated the efficacy of arthrocentesis in the treatment of temporomandibular joint (TMJ disorders. Material and Methods. In this prospective clinical case series, 30 consecutive patients with TMJ disorders underwent arthrocentesis using saline and sodium hyaluronate injections. Outcome measures were TMJ pain, maximum mouth opening (MMO, joint noises, and anatomical changes in the TMJ architecture. Patients were evaluated using cone-beam computed tomography (CBCT and magnetic resonance imaging (MRI at the beginning of treatment and 60 days after the last arthrocentesis. Pretreatment and posttreatment clinical parameters were compared using paired and unpaired t-tests, and McNemar’s test was used to evaluate CBCT and MRI changes (. Results. At 1-year follow-up examinations, visual analogue scale scores indicated that pain was reduced significantly and mean postoperative MMO was increased significantly. CBCT findings showed no significant change, and MRI showed only slight reductions in inflammatory signs. Conclusions. Within the limitations of this study, we can conclude that arthrocentesis is a simple, minimally invasive procedure with a relatively low risk of complications and significant clinical benefits in patients with TMJ disorders. This trial is registered with NCT01903512.

    The aim of this study is to present the preliminary clinical data on the OMX Temporomandibular Joint (TMJ) Prosthetic total joint replacement system. A prospective, cohort, clinical study was undertaken of consecutive adult patients with Category 5 end-stage joint disease who were implanted with the OMX TMJ prosthesis between May 2015 and April 2017. A total of 50 devices were implanted in 38 patients, with 12 patients receiving bilateral prosthetic joints. There were 31 females and 7 males in this cohort, who ranged in age from 20 to 66 years, with a mean of 43.8 years (±14.0 years). Ten of the 50 prosthetic joints (20%) were fully customized, while the remaining were patient matched using virtual planning software. Based on a mean follow-up period of 15.3 months (range 12-24 months) following the TMJ total joint replacement, preliminary results suggest the OMX TMJ prosthesis has made a positive impact on clinical outcomes, with a mean 74.4% reduction in joint pain levels and significant improvements (p < 0.05) in jaw function as measured by the visual analogue scales for mouth opening (30.8%), diet (77.1%), and function (59.2%). No device failures were reported during the study period. This study suggests that the print-on-demand OMX TMJ prosthesis, designed for rapid delivery of both patient-matched and fully customize devices, represents a safe, reliable and versatile implantable joint replacement system for the treatment of category 5 end-stage TMJ disease.

    Full Text Available BACKGROUND AND AIM: The aim of this study was to assess the association between the clinical and cone-beam computed tomography (CBCT findings in relation to bony changes in patients with temporomandibular disorders (TMD. METHODS: According to the research diagnostic criteria for temporomandibular disorder (RDC/TMD, forty-one patients with type II TMD (42 TM joints and type III TMD (40 TM joints were recruited for this study. Condylar position and bony changes including flattening, sclerosis, osteophytes, resorption, and erosion of joint were evaluated by CBCT and compared with clinical findings. Data were analyzed by SPSS software. RESULTS: Condylar flattening, sclerosis, resorption, and erosion were not significantly associated with joint/masticatory muscles pain or crepitus sound. The vertical or horizontal position of the condyle showed no significant relationship with the clinical findings. Condylar osteophyte was significantly associated with pain in masticatory muscles and crepitus (P = 0.030 and P = 0.010, respectively. There was no association between the condylar range of motion and pain in joint or masticatory muscles. CONCLUSION: Condylar osteophyte was significantly associated with both masticatory muscles pain and crepitus sound. No significant relationship was found between the other temporomandibular joint (TMJ radiographic and clinical findings in patients with TMD.

    Full Text Available The articular disc of the temporomandibular joint (TMJ is composed of fibrocartilage, and the extracellular matrix of this disc is composed mainly of collagen, glycosaminoglycan and proteoglycans. Research on the changes that occur in the composition of the articular disc of the TMJ is necessary for understanding the basis of the pathological process of internal derangement (ID, and a number of reports have been published in recent years on the application of refined histochemical techniques to investigate the structure and function of the TMJ. The direction of future TMJ disc studies should be towards obtaining more evidence to support previous results, and should hopefully be of practical use in terms of prevention and cure of ID.

    The aim of this study was to evaluate the feasibility of using preshaped hydroxyapatite/collagen condyles as carriers for platelet-rich plasma after gap arthroplasty in patients with temporomandibular ankylosis, to assess the aesthetic and functional outcomes, and to find out if neocondylar regeneration was possible. We studied 19 patients with temporomandibular joint ankylosis (25 joints), in whom preshaped hydroxyapatite/collagen condyles with platelet-rich plasma were fixed to the ramus with a titanium miniplate, and temporal fascia was placed in between. We evaluated the type of ankylosis, mouth opening before and after operation, deviation on mouth opening, lateral excursion, protrusion, postoperative anterior open bite, radiographic assessment, and complications. All patients showed appreciable improvements in mouth opening and excursion of the jaw. There were a few complications such as mild fever, and temporary involvement of the facial nerve, which improved with time. No open bite or recurrence was reported during the 18 months' follow up. Radiographic evaluation at 3 months showed a less opaque condyle, but the opacity at 18 months was more defined, suggesting a newly formed condyle. A preshaped hydroxyapatite/collagen condyle with platelet-rich plasma improves both aesthetics and function. However, a long term study is required to follow the growth patterns to see if the patients develop any facial deformity as they grow.

En nuestro país se han llevado a cabo en las 2 últimas décadas, varios estudios epidemiológicos sobre los trastornos temporomandibulares (TTM y se ha hecho un esfuerzo notable por esclarecer su causa. De forma general, se acepta la idea de que el origen de los disturbios funcionales del sistema estomatognático es multifactorial, pero a pesar de que tanto en niños como en adultos la prevalencia de los trastornos temporomandibulares (TTM ha sido alta, no se ha evidenciado un factor causal predominante. La literatura alude que estas disfunciones afectan a un porcentaje muy elevado de la población mundial (80 %, con una edad media de 34 años y una proporción de 3 mujeres por cada hombre. Este dato es muy interesante, porque los estudios precisan que las mujeres de edades comprendidas entre los 25 y los 35 años presentan trastornos temporomandibulares (TTM con más asiduidad.A documental review of different sources was carried out to study the disfunctions of temporal mandibular joint (TMJ with the objective of updating and enlarge our knowledge of this disorder.

    2016-07-01

    Chondrosarcoma is the second most common sarcoma arising in the bone, but it rarely involves the temporomandibular joint (TMJ). To date, 30 cases of TMJ chondrosarcoma have been reported in the English literature, and the authors report an additional case arising from a cystic lesion in a 60-year-old female patient. The clinical and radiological diagnosis of the lesion was initially synovial cyst, and periodic check-ups were done after aspiration of the lesion. After three years, the patient perceived swelling of the lesion, and surgical excision was performed. The final diagnosis was grade I chondrosarcoma. When clinicians detect a cystic lesion in the radiographic imaging of the TMJ, chondrosarcoma should be included in the differential diagnosis. In addition, computed tomography (CT) as well as magnetic resonance imaging (MRI) is recommended for the accurate diagnosis and proper preoperative planning in TMJ chondrosarcoma.

    We examined the frequency of incidentally found or unexpected tumors discovered at the time of magnetic resonance imaging (MRI) examinations in the temporomandibular joint (TMJ) region for patients with suspicion of TMJ arthrosis. Five MR images (T1-weighted transverse scout image and proton density and T2-weighted oblique sagittal images at the open and closed mouth) were acquired. In 2776 MRI examinations of TMJ arthrosis, two tumors were discovered. They consisted of an adenoid cystic carcinoma in the deep portion of the parotid gland, and a malignant tumor extending from the infratemporal fossa to the parapharyngeal space. The rate of incidentally founded or unexpected tumors in TMJ examinations was low (0.072%), but the two tumors found were malignant tumors, and therefore, scout image should be carefully examined, not only used for positing the slice

Five MR images (T1-weighted transverse scout image and proton density and T2-weighted oblique sagittal images at the open and closed mouth) were acquired. In 2776 MRI examinations of TMJ arthrosis, two tumors were discovered. They consisted of an adenoid cystic carcinoma in the deep portion of the parotid gland, and a malignant tumor extending from the infratemporal fossa to the parapharyngeal space. The rate of incidentally founded or unexpected tumors in TMJ examinations was low (0.072%), but the two tumors found were malignant tumors, and therefore, scout image should be carefully examined, not only used for positing the slice.

    Full Text Available Temporomandibular disorders (TMD are clinical conditions characterized by pain and sounds of the temporomandibular joint (TMJ. This study was designed to assess the effect of low-level laser therapy (LLLT on healing of osteoarthritis in rats with TMD.Thirty-two male Wistar rats (250-200 g were housed in standard plastic cages. After injection of Complete Freund's adjuvant into the TMJ, rats were randomly divided into two groups of 16 (case and control and anesthetized; then osteoarthritis was induced via intraarticular injection of 50 µl of Complete Freund's adjuvant; into the bilateral TMJs. In the case group, LLLT was done transcutaneously for 10 minutes daily, starting the day after the confirmation of osteoarthritis. Exposure was performed for 10 minutes at the right side of the TMJ with 880 nm low-level laser with 100 mW power and a probe diameter of 0.8 mm. Control rats were not treated with laser.After three days of treatment the grade of cartilage defects, number of inflammatory cells, angiogenesis, number of cell layers and arthritis in rats in the case group were not significantly different compared with controls (P>0.05. After seven days, the grade of cartilage defects, number of inflammatory cells, number of cell layers, and arthritis in the case group improved compared to controls (P<0.05; angiogenesis in both groups was similar.Treatment of TMD with LLLT after 7 days of irradiation with a wavelength of 880 nm was associated with a greater improvement compared to the control group.

    To estimate the incidence of disc displacement, disc deformity, and bone changes of the temporomandibular joint in elderly patients with temporomandibular disorders, 55 elderly patients (110 joints) were examined by magnetic resonance imaging. The ages of the patients ranged from 65 to 89 years (average, 70 years). They consisted of 13 men and 42 women. Normal disc position was found in 40 joints (36.4%), anterior disc displacement with reduction in 17 joints (15.5%), and anterior disc displacement without reduction in 53 joints (48.2%) on magnetic resonance imaging. Thirty-eight (71.6%) of the 53 joints with anterior disc displacement without reduction had disc deformity and 33 (62.3%) had bone changes. The frequency of bone changes in the elderly group was higher than that in the younger group. Women had a higher incidence of bone changes than men. (author)

  15. Temporomandibular joint assessment in patients with articular disc displacement by way of computed tomography - radiological parameters of shape, size and location of mandibular heads

    Full Text Available Conventional and modern methods of radiological imaging are often used in the diagnosis of temporomandibular joint disorders, and the CT technique is particularly characterized by an excellent visualization of bony structures. The aim of the study was to show the importance and role of CT in the evaluation of TMJ bone structures in both patients with articular disc displacement and in a group of healthy subjects. Both study groups were assessed with the use of the transverse plane. Herein, multi-slice spiral computed tomography was performed in 47 subjects. These individuals were qualified for CT by way of magnetic resonance imaging, due to their being diagnosed with a displacement of their temporomandibular joint disc. The product of our study is presented as a set of tables. These are comparisons of radiological parameters based on the shape, size and location of the mandibular head, in the examined patients, in a control group, and with regard to sex. The results of our work indicate that CT can be successfully used in the imaging of TMJ bone structures, specifically, the condylar process of the mandibular head and the joint socket. However, statistically significant differences of the utilized parameters between patients with articular disc displacement and controls, warrant further analysis of this issue.

    Ten temporomandibular joints (TMJs) of 5 healthy volunteers and 19 TMJs of internal derangements in 16 patients with splint therapy were examined with MR imaging. T1-weighted images were obtained only in the closed mouth position, and gradient recalled acquisition in steady state (GRASS) images were obtained in active opening and closing phases, allowing a pseudodynamic display of TMJ movement. All patients received protrusive splint treatment. The usefulness of MR imaging to assess the efficacy of splint therapy was evaluated. Corrected disk position with the splint in place was clearly demonstrated in 9 TMJs, corresponding with elimination of reciprocal clicking. Ten other TMJs of anterior disk displacement without reduction showed uncorrected disk position by the splint. This information could confirm the therapeutic efficacy, or suggest other treatment alternatives. GRASS MR imaging can provide accurate and physiologic information about disk function in initial and follow-up assessment of protrusive splint therapy. (orig.).

    Chondrosarcoma is a malignant mesenchymal tumour of cartilaginous origin. It represents 11% of all malignant primary bone tumours, and the pelvis, ribs, femur and humerus are most frequently involved. Chondrosarcoma of the head and neck region is a rare disease, and represents approximately 0.1% of all head and neck neoplasms. This report describes a rare localisation of chondrosarcoma in a 56-year-old man who presented with swelling in the right preauricular area and mild limitation and pain in the mouth opening. Since 1959, just a few cases of temporomandibular joint (TMJ) chondrosarcoma have been described. Computed tomography revealed a large mass (39 x 46 x 40 mm) in the right preauricular and parotid region with morpho-structural alterations of the condyle and an intense periostotic reaction. The tumour was treated by total parotidectomy and condylotomy. The VII cranial nerve was preserved. Histopathologic examination revealed a low grade chondrosarcoma with a 50% proliferation index. At present, the patient is still receiving routine follow-up after radiotherapy and physiotherapy.

    Temporomandibular Joint (TMJ) ankylosis is a situation in which the mandibular condyle is fused to the glenoid fossa by bone or fibrous tissue. The management of TMJ ankylosis has a complicated chore and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of re-ankylosis. Interpositional gap arthroplasty is one of the modalities for its management. A range of inter-positional materials have been used to avert recurrence after gap arthroplasty in TMJ anky...

    The most common temporomandibular joint (TMJ) internal derangement is an abnormal relationship of the disc with respect to the mandibular condyle, articular eminence and glenoid fossa-disc displacement. The aim of our study was to analyse the correlation between partial/complete disc displacement in the intercuspal position (IP) and its reduction in the open-mouth position (OMP) in both oblique sagittal and coronal planes on magnetic resonance imaging (MRI) in patients with temporomandibular disorders. Multisection MRI analysis of 382 TMJs was conducted in 191 patients with disc displacement according to the RDC/TMD criteria (148 women, 43 men; aged 14-60 years). The disc position was evaluated on all oblique sagittal and coronal images in the IP and the OMP. Univariate logistic regression analysis showed that the severity of disc displacement in the sagittal plane is a statistically significant predictor of reduction ability during mouth opening (B = 3.118; P displacement in both planes is also a significant predictor of disc reduction in OMP (B = 2.200; P displacement in IP, in both sagittal and coronal planes. Multisection analysis of all MR images allows distinguishing the correct disc position from disc displacement and can improve the ability to distinguish between various stages of TMJ internal derangement. © 2017 John Wiley & Sons Ltd.

    The standing posture of humans has created both morphological and functional adaptations in the temporo-mandibular joint and the masticatory function. This biped state is the one of the most important characteristic of human evolution. It is furthermore the agent determining most of the functional changes in the whole body. This survey will be carried out in several levels including, a descriptive anatomy, biomechanics, radiological imaging, functioning in the articulation of TMJ. The descriptive anatomic picture will be obtained by the traditional dissection techniques. 20 TMJ joints are dissected from 10 cadavers: 7 cadavers, 65-75 year old, 3 cadavers, 60-65 year old. The x-rays are lateral view and the subjects of the radiological imaging are young's, adults and olds: 1, 3 y-old Male; 1, 7 y-old Female; 1, 14 y-old Female; 10, 19-23 y-old Male; 1, 26 y-old Female; 1, 34 y-old Male; 1, 75 y-old Female. The anatomic elements in the TMJ well resembled the ones described in the literature of the capsule, the ligament, the masticator muscles (masseter, temporal, medial and lateral pterygoids). The temporo-mandibular ligament proved to be difficult to separate from the capsule in some of the specimens. Sometimes it was not always found after a dissection.

    Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder of the synovial membrane. PVNS generally affects large joints but occasionally involves the temporomandibular joint (TMJ), with occasional extension into the middle cranial fossa. The purpose of this study was to report our experience with PVNS along with a focused literature review. Patients with PVNS of the TMJ treated at the University of California - San Francisco from 2007 to 2013 were reviewed. A PubMed search was performed to identify additional cases. Five patients underwent surgical resection, with 1 recurrence at 61 months. A literature review identified 58 patients, 19 of which had intracranial involvement. Interestingly, intracranial extension was more common in men. Intracranial extension was not associated with an increased rate of recurrence. PVNS of the TMJ is a rare entity associated with excellent outcomes, even with intracranial extension. Management should consist of maximal resection, with radiotherapy reserved for extensive or recurrent lesions. © 2014 Wiley Periodicals, Inc.

  4. Comparison of three radiographic methods in screening of temporomandibular joint involvement in patients with psoriatic arthritis

    1990-01-01

    Fifty-three randomly selected subjects with psoriatic arthritis (PA) were examined radiographically by means of orthopantomography, transcranial radiography, and transmaxillary radiography. Two examiners graded the radiographic signs of flattening, osteophytes, erosion, and sclerosis. The findings obtained were then compared to determine the best technique for screening of temporomandibular joint (TMJ) bone changes. Together the techniques showed definite (24%) and possible (6%) changes, suggesting TMJ involvement in 31 of 106 joints. In all projections, radiographic signs suggesting TMJ involvement were most frequent in the condyle. Erosion in the condyle was the most frequent finding. Agreement with regard to definite changes in the condyle was found in only one-third to half of the cases. It is concluded that in radiography of the TMJ in subjects with PA, a combination of radiographic techniques should be used to obtain maximum information. However, orthopantomography is well suited for screening of TMJ involvement in subjects with PA. 30 refs., 2 figs., 3 tabs

    Temporomandibular joint (TMJ) arthroscopy is a minimally invasive surgical approach for intra-articular TMJ diseases. Office-based arthroscopy using the smallest TMJ scope allows for good visualization, as well as the ability to lavage the joint in an office setting. This study aimed to assess the efficacy of an office-based TMJ arthroscopic technique. A retrospective evaluation of 363 patients with a TMJ disorder was performed. These patients underwent office-based arthroscopy using the OnPoint 1.2mm Scope System (Biomet Microfixation, Jacksonville, FL, USA) in Florida, USA, from July 2007. The following outcomes of the procedure were assessed: improvement in painless range of mandibular motion, pain on loading, and functional jaw pain; these were evaluated using a visual analog scale (VAS) over an average follow-up period of 263.81±142.1 days. The statistical analysis was performed using IBM SPSS Statistics version 20. Statistically significant improvements in TMJ pain and function, and other variables (P=0.001) were shown following TMJ arthroscopic lysis and lavage. Office-based arthroscopy using the OnPoint System was demonstrated to be a safe and efficient procedure for the treatment of patients with TMJ disorders as the first level of the algorithm of care.

    The purpose of this study is to describe the methodological innovations of a web-based system for storage, integration and computation of biomedical data, using a training imaging dataset to remotely compute a deep neural network classifier of temporomandibular joint osteoarthritis (TMJOA). This study imaging dataset consisted of three-dimensional (3D) surface meshes of mandibular condyles constructed from cone beam computed tomography (CBCT) scans. The training dataset consisted of 259 condyles, 105 from control subjects and 154 from patients with diagnosis of TMJ OA. For the image analysis classification, 34 right and left condyles from 17 patients (39.9 ± 11.7 years), who experienced signs and symptoms of the disease for less than 5 years, were included as the testing dataset. For the integrative statistical model of clinical, biological and imaging markers, the sample consisted of the same 17 test OA subjects and 17 age and sex matched control subjects (39.4 ± 15.4 years), who did not show any sign or symptom of OA. For these 34 subjects, a standardized clinical questionnaire, blood and saliva samples were also collected. The technological methodologies in this study include a deep neural network classifier of 3D condylar morphology (ShapeVariationAnalyzer, SVA), and a flexible web-based system for data storage, computation and integration (DSCI) of high dimensional imaging, clinical, and biological data. The DSCI system trained and tested the neural network, indicating 5 stages of structural degenerative changes in condylar morphology in the TMJ with 91% close agreement between the clinician consensus and the SVA classifier. The DSCI remotely ran with a novel application of a statistical analysis, the Multivariate Functional Shape Data Analysis, that computed high dimensional correlations between shape 3D coordinates, clinical pain levels and levels of biological markers, and then graphically displayed the computation results. The findings of this

    This study determines the value of three-dimensional (3-D) sonography for the assessment of disk dislocation of the temporomandibular joint (TMJ). Sixty-eight patients (i.e.,136 TMJ) with clinical dysfunction were examined by 272 sonographic 3-D scans. An 8- to 12.5-MHz transducer, angulated by step-motor, was used after picking a volume box on 2-D scan; magnetic resonance imaging followed immediately. Every TMJ was scrutinized in closed- and open-mouth position for normal or dislocated disk position. Fifty-three patients had complete data sets, i.e., 106 TMJ, 212 examinations. Sonographic examination took 5 min, with 74% specificity (62% closed-mouth; 85% open-mouth); sensitivity 53% (62/43%); accuracy 70% (62/77%); positive predictive value 49% (57/41%); and negative predictive value 77% (67/86%). This study encourages more research on the diagnostic capacity of 3-D TMJ sonography, with the advantage of multidimensional joint visualization. Although fair in specificity and negative predictive value, sensitivity and accuracy may ameliorate with future higher-sound frequency, real-time 3-D viewing and automated image analysis.

    1994-01-01

    The morphological changes of the mandibular condyle in patients with temporomandibular joint disorder were studied. The subjects were 420 patients (103 males and 317 females, 8 to 80 years of age, mean age 39.8 years) who were clinically diagnosed as temporomandibular joint disorder. MR imaging was performed with a GE-Signa 1.5 Tesla MR imaging system using the body coil as a transmitter and 3-inch bilateral surface coils. The patients were examined by a multiplanar gradient echo technique in a closed-loop cine fashion on both sagittal and coronal planes. The results obtained were as follows: 1) Morphological changes of the mandibular condyle were detected in 47.0% of the patients. The predominant morphological changes were then formation of osteophyte and marginal proliferation (65.8%). 2) The incidence of morphological changes in the mandubular condyle did not show any significant difference between male and female, and tended to be higher in patients over 40 years of age, and the incidence in patients under 20 years of age was lower, compared to that in patients from 20 to 39 years of age. 3) The incidence of morphological changes in patients with anterior disk displacement without reduction was higher than in those with anterior disk displacement with reduction (P<0.001). The incidence of morphological changes in patients with rotational disk displacement was higher than in those with medial disk displacement (P<0.001). 4) The anterior translation of mandibular condyle was influenced more by anterior disk displacement rather than by morphological changes. From these results. it is suggested that simultaneous bilateral condyle pseudodynamic MR imaging was useful in the diagnosis of internal derangement, evaluation of morphological changes and assessment of motional abnormality of the condyle.

    To compare prevalences of self-reported comorbid headache, neck, back, and joint pains in respondents with temporomandibular joint and muscle disorder (TMJMD)-type pain in the 2000-2005 US National Health Interview Survey (NHIS), and to analyze these self-reported pains by gender and age for Non-Hispanic (NH) Whites (Caucasians), Hispanics, and NH Blacks (African Americans). Data from the 2000-2005 NHIS included information on gender, age, race, ethnicity, education, different common types of pain (specifically TMJMD-type, severe headache/migraine, neck, and low back pains), changes in health status, and health care utilization. Estimates and test statistics (ie, Pearson correlations, regressions, and logistic models) were conducted using SAS survey analysis and SUDAAN software that take into account the complex sample design. A total of 189,977 people (52% female and 48% males, 73% NH Whites, 12% Hispanic, 11% NH Blacks, and 4% "Other") were included. A total of 4.6% reported TMJMD-type pain, and only 0.77% overall reported it without any comorbid headache/migraine, neck, or low back pains; also 59% of the TMJMD-type pain (n = 8,964) reported ⋝ two comorbid pains. Females reported more comorbid pain than males (odds ratio [OR] = 1.41, P neck pain, 64% low back pain, and 62% joint pain. Differences in gender and race by age patterns were detected. For females, headache/migraine pain with TMJMD-type pain peaked around age 40 and decreased thereafter regardless of race/ethnicity. Neck pain continued to increase up to about age 60, with a higher prevalence for Hispanic women at younger ages, and more pronounced in males, being the highest in the non-Whites. Low back pain was higher in Black and Hispanic females across the age span, and higher among non-White males after age 60. Joint pain demonstrated similar patterns by race/ethnicity, with higher rates for Black females, and increased with age regardless of gender. TMJMD-type pain was most often associated with

    Full Text Available Abstract Background Many epidemiological studies of temporomandibular disorders (TMDs in children and adolescents have been performed. However, the results of such studies have varied, and a comprehensive view of the prevalence and severity of symptoms and signs is difficult to obtain. In the present study, temporomandibular joint (TMJ sounds, which are the most common signs and symptoms of TMD, were observed longitudinally, and the need for treatment was evaluated. Methods Seventy individuals in six age groups (5, 6, 7, 8, 9, and 10 years old at the beginning of the observation period participated in an epidemiological investigation conducted between 1987 and 1992. During each clinical examination, the following parameters were examined: maximum unassisted jaw opening, TMJ clicking, and the coincidence or difference between the midlines of the upper central incisors and the lower central incisors. In addition, the bilateral bite force was recorded, and the numbers of erupted, decayed, and filled teeth were recorded. Results Eight individuals dropped out because they moved. No TMJ dysfunction requiring treatment was observed in this series. TMJ clicking was observed in 30 subjects (48%; however, this symptom was temporary in most of subjects (26 subjects; 42%, and only 3 subjects (5% had persistent clicking (continuing until the end of the observation period. The incidences of clicking were not significantly different among the six groups (x2 = 4.265. Clicking was significantly more common among girls (19 subjects than among boys (11 subjects; P = 0.042. A significantly lower bite force (17 ± 18 kg was recorded for the subjects with persistent clicking, compared with that of the other subjects (8- and 9-year-olds; mixed dentition without persistent clicking (32 ± 17 kg. The persistent clicking began at an age of 11 or 12 years (permanent dentition. Conclusion Most of the clicking observed in the children and adolescents was temporary, and no

  14. How effective are geometric morphometric techniques for assessing functional shape variation? An example from the great ape temporomandibular joint.

    Functional shape analyses have long relied on the use of shape ratios to test biomechanical hypotheses. This method is powerful because of the ease with which results are interpreted, but these techniques fall short in quantifying complex morphologies that may not have a strong biomechanical foundation but may still be functionally informative. In contrast, geometric morphometric methods are continually being adopted for quantifying complex shapes, but they tend to prove inadequate in functional analyses because they have little foundation in an explicit biomechanical framework. The goal of this study was to evaluate the intersection of these two methods using the great ape temporomandibular joint as a case study. Three-dimensional coordinates of glenoid fossa and mandibular condyle shape were collected using a Microscribe digitizer. Linear distances extracted from these landmarks were analyzed using a series of one-way ANOVAs; further, the landmark configurations were analyzed using geometric morphometric techniques. Results suggest that the two methods are broadly similar, although the geometric morphometric data allow for the identification of shape differences among taxa that were not immediately apparent in the univariate analyses. Furthermore, this study suggests several new approaches for translating these shape data into a biomechanical context by adjusting the data using a biomechanically relevant variable.

    Osteoarthrosis associated with findings of avascular necrosis of the mandibular condyle on magnetic resonance imaging was clinically evaluated. The subjects consisted of 5 female unilateral cases, with an average age of 55.4 years who had a mean duration of illness of 15.2 months. The symptoms were a mean interincisal opening distance of 32.8 mm with arthralgia in mild to moderate degree, and joint noise (crepitation) in all joints. MRI documented decreasing signal intensity of the condyle with 2 joints in high degree and 3 joints in moderate, as well as variable low signal density of the articular eminence, associated with concomitant anterior disk displacement. X-ray showed deformity of the condyle and eminence. The operative findings disclosed disk rupture and comparatively smooth cartilage with minimum remodeling of the condylar surface; however, avascular evidence was suggested when corticotomy was performed. 4 joints underwent diskectomy, condylar shaving, auricular cartilage grafts and corticotomy of the condyle. Arthroscopic corticotomy was applied for 1 joint with mild symptoms. Postoperative symptoms improved to mean opening distance of 41.4 mm and disappeared arthralgia in 4 joints. The surgical outcome was excellent in 3 joints and good in 2 joints. Follow-up MRI in 2 cases disclosed increasing signal intensity, which suggested recovery of condylar vascularity following corticotomy. It is suggested that the low-signal intensity on MRI in osteoarthrosis might indicate avascular lesions of the condyle, secondary to degenerative change. Histological investigations are required to evaluate avascular necrosis of the temporomandibular joints. (author)

    To evaluate the relationship between internal derangement and osteoarthrosis in the temporomandibular joint (TMJ) using magnetic resonance imaging (MRI). 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. 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. The relationship between internal derangement and osteoarthrosis is obscure, but it is thought that both disorders adversely affect each other.

    The aim of this study was to assess the prevalence of erosive osseous changes of the articular eminence in the temporomandibular joint without internal derangement. Sixty joints of 30 consecutive patients with mandibular prognathism were evaluated with both MR imaging and helical CT. On MPR images obtained with helical CT, erosive osseous changes of the articular eminence were observed in 18 joints (30%) of 13 patients. None of the joints studied demonstrated an osseous change in the mandibular condyle. MR imaging failed to detect erosive osseous changes of the articular eminence in all of the joints studied. In conclusion, MPR images obtained with helical CT were of value to detect erosive osseous changes of the articular eminence. (author)

    The objective of this systematic review was to examine the effect of orthognathic surgery (OS) on the temporomandibular joint and oral function. Electronic databases were systematically searched for studies published until October 2015. Articles were assessed against predefined inclusion criteria. The included papers were divided into four groups based on the type of OS performed. The following items were recorded: quality of evidence using the Oxford Centre for Evidence-Based medicine (CEBM) criteria, number of patients, presence/absence of controls, mean age at treatment, follow-up time, clinical examination findings, bite force, use of the Helkimo Index and Research Diagnostic Criteria for Temporomandibular Disorders, imaging findings, and patient questionnaire results. A total of 4669 articles were identified; 76 relevant articles were included in the review. These studies assessed a total 3399 patients and 380 controls, with a mean age of 25.4 years. The great variety of OS techniques, examination techniques, diagnostic criteria, and imaging techniques used in the articles studied, as well as the quality of the study designs, made it difficult to compare studies and to draw conclusions. However, looking at the different aspects studied in general, it can be stated that OS seems to have little or no harmful effect on the TMJ and oral function (level of evidence: levels II, III, and IV).

    Full Text Available Occlusal splints are a standard method to treat disc displacement with reduction of the temporomandibular joint (TMJ. They can be classified into three major groups on the basis of function: stabilization splints, distraction splints (pivot, and anterior repositioning splints. The aim of this paper is to introduce a modified mandibular splint, the Kaohsuing Medical University splint, and its associated treatment regimen for management of disc displacement with reduction of the TMJ. The key points for fabrication of the KMU splint include the occlusal surface of the mandibular splint must be indented and average bite elevation 1.5 mm vertically. The patient should wear it 24 hours a day for the first 4 weeks, then wear it while eating and sleeping for the next 2 weeks, and wear it only while sleeping for the last 2 weeks. Patients must understand that the success of treatment depends on their compliance with the regimen.

    No epidemiological studies have targeted the association between experience of orthodontic treatment and symptoms of temporomandibular joint (TMJ) in a large adult population. In this study, we investigated whether experience of orthodontic treatment is associated with symptoms of TMJ in adults. We used data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V), conducted in 2011. Trained dentists asked subjects to report their experience of orthodontic treatment and symptoms of TMJ. Overall, 5936 subjects aged over 19 yr were included in this study (2528 males). The data were analyzed using the chi-square test and multiple logistic regression tests. The group with experience of orthodontic treatment had more symptoms of TMJ than the group without orthodontic experience. After adjusting for all covariates (i.e., age, sex, marital status, income, education, stress, teeth injury, and occupation), the adjusted odds ratio was 2.53 (95%CI 1.74-3.67). Experience of orthodontic treatment could be related to increased symptoms of TMJ.

    To identify signs of temporomandibular disorders and cervical pain in individuals with episodic and chronic (transformed) migraine (CM), relative to controls without headaches. In this prospective, controlled, double-blind study, we examined 93 individuals divided in 3 groups: episodic migraine EM, (n=31), CM chronic migraine (n=34), and controls without migraine (n=28). We recorded signs of temporomandibular disorders, and of pain in the neck, after the protocol of Helkimo (1974). We calculated the odds ratio (OR) and confidence intervals (CI) of symptoms as a function of headache status. Data from all groups were paired and compared using the chi test. The level of significance was 5% in 2-tailed tests. Relative to controls, participants with EM and CM were significantly more likely to have tenderness in the masticatory muscles [controls=28%, migraine=54%, (OR=3.0, 95% CI=1.1-8.9), CM=73% (OR=6.9, 95% CI=2.3-21.2)], and in the temporomandibular joint [controls=25%, migraine=61%, (OR=4.7, 95% CI=1.5-14.5), CM=61% (OR=4.8, 95% CI=1.6-14.5)]. They were numerically (but nonsignificantly) more likely to have limited lateral jaw movements (CM=34%; EM=26%; NP=18%), joint sounds (CM=44%; EM=29%; NP=28%), and tenderness in neck muscles (CM=64%; EM=51%; NP=35%). In a tertiary care population, individuals with EM and CM are more likely to have tenderness at the temporomandibular joint and on the masticatory muscles, relative to controls. Studies are needed to investigate whether treatment of 1 disorder will improve the other.

  8. Natural history of minimal anterior displacements of the temporomandibular joint meniscus

    Drace, J.E.

    1988-01-01

    Magnetic resonance (MR) imaging of the temporomandibular joint (TMJ) often provides more precise localization of the meniscus than other imaging modalities. Previous study of the distribution of meniscus position in a control population showed that anterior displacements of more than 10 0 were more than 2 standard deviations from the mean, but the clinical significance and natural history of minimal displacements remained uncertain. Twenty follow-up MR studies were performed after 1-2 years in subjects with minimal meniscus displacements drawn from an original series of 125 symptomatic patients and 50 asymptomatic volunteers. These were correlated with repeated clinical histories and clinical examinations. A significant increase in the amount of anterior displacement was found in 55% of the originally asymptomatic volunteers with minimal displacements, which was accompanied by new symptoms in 40%. This was seen exclusively among those with a history of orthodontia. Worsening anterior displacements were seen in 50% of the patient population, and 25% had associated worsening symptoms. These findings indicate that detection of even minimal displacements of the TMJ meniscus is necessary and warrants follow-up MR examinations. Routine follow-up MR images should be obtained following malocclusion treatment and after major dental procedures

    This study aimed to evaluate the possibility of any correlation between disc displacement and parameters used for evaluation of skull positioning in relation to the cervical spine: craniocervical angle, suboccipital space between C0-C1, cervical curvature and position of the hyoid bone in individuals with and without symptoms of temporomandibular dysfunction. The patients were evaluated following the guidelines set forth by RDC/TMD. Evaluation was performed by magnetic resonance imaging for establishment of disc positioning in the temporomandibular joints (TMJs) of 30 volunteer patients without temporomandibular dysfunction symptoms and 30 patients with symptoms. Evaluation of skull positioning in relation to the cervical spine was performed on lateral cephalograms achieved with the individual in natural head position. Data were submitted to statistical analysis by Fisher's exact test at 5% significance level. To measure the degree of reproducibility/agreements between surveys, the kappa (K) statistics was used. Significant differences were observed between C0-C1 measurement for both symptomatic (p=0.04) and asymptomatic (p=0.02). No statistical differences were observed regarding craniocervical angle, C1-C2 and hyoid bone position in relation to the TMJs with and without disc displacement. Although statistically significant difference was found in the C0-C1 space, no association between these and internal temporomandibular joint disorder can be considered. Based on the results observed in this study, no direct relationship could be determined between the presence of disc displacement and the variables assessed.

    Congenital deformities of the mandibular ramus and of the temporo-mandibular joint are treated by surgery since the early 20th century. However, morphological and functional results are often disappointing, accounting for iterative operations. Today, a clear consensus concerning the type of intervention to be proposed, and at what age it should be carried out does not yet exist. For mild cases, "conventional" orthognathic or osteogenic distraction procedures seem to work well, especially if they are carried out at the end of growth. In severe cases, it is often necessary to proceed in several surgical steps, usually starting with a chondrocostal graft, especially when interceptive surgery, performed before the end of growth, is preferred in order to improve the patient's quality of life.

    2017-04-01

    This study was designed to determine the stability of counterclockwise rotation (CCWR) of the maxillomandibular complex (MMC) in orthognathic surgery with or without surgical correction of coexisting temporomandibular joint (TMJ) pathology. The authors implemented a systematic review and meta-analysis. A search of major databases through PubMed, EMBASE, and Cochrane CENTRAL was performed. Inclusion criteria were studies that analyzed CCWR of the MMC in regard to skeletal stability after orthognathic surgery in patients with or without pre-existing TMJ pathology that was or was not surgically corrected concomitantly. The predictor variables were patients who underwent CCWR of the MMC in the following subgroups: 1) healthy TMJs (presumed healthy based on history, clinical evaluation, and radiographic analysis but without magnetic resonance imaging [MRI] confirmation), 2) no TMJ assessment, 3) untreated TMJ disc displacement (confirmed by MRI), 4) TMJ disc displacement (confirmed by MRI) repositioned using Mitek anchors, and 5) reconstruction with TMJ total joint prosthesis. Outcome variables were surgical relapse for angular and linear measurements. Postsurgical mean changes for the occlusal plane (OP) and linear measurements using a fixed-effects model with a 95% confidence interval were analyzed. A total of 345 patients enrolled in 12 studies were included in this study. There was significant OP relapse and horizontal relapse at the B point and menton for studies with untreated TMJ disc displacement and studies without TMJ assessment (P < .005). There was significant horizontal relapse at the A point for studies with healthy TMJs, without assessment of the TMJs, and with TMJ reconstruction with total joint prostheses (P < .005). There was no significant vertical relapse at the B and A points for all subgroup analyses (P < .005). The result of the meta-analysis suggests that CCWR of the MMC is a stable procedure for patients with healthy TMJs, patients undergoing

    The purpose of this study was to assess the safety and the accuracy of surgical navigation technology in the resection of severe ankylosis of the mandibular condyle with the middle cranial fossa. The computed tomography scan data were transferred to a Windows-based computer workstation, and the patient's individual anatomy was assessed in multiplanar views at the workstation. In the operation, the patient and the virtual image were matched by individual registration with the reference points which were set on the skull bone surface and the teeth. Then, the real-time navigation can be performed. The acquisition of the data sets was uncomplicated, and image quality was sufficient to assess the operative result in 2 cases. Both of the operations were performed successfully with the guidance of real-time navigation. The application of surgical navigation has enhanced the safety and the accuracy of the surgery for bony ankylosis of temporomandibular joint. The use of surgical navigation resulted in the promotion of accurate and safe surgical excision of the ankylosed skull base tissue.

    Purpose: The temporomandibular dysfunction is a common pathology. It appears with many symptoms as: joint pain, mechanic disturbance, and loss of mouth motion. The Magnetic Resonance Image is the chose method to study these alterations. The purposes of this paper are to demonstrate according to sex, the distribution of temporomandibular dysfunction and to determinant the relationships between the disc dislocation and the degenerative disease of the junction. Material and Method: 215 patients were evaluated between January 1999 and August 2004. An Elscint MRI 2 Tesla machine was used with Spin-echo (T1 and T2) Fat-sat sequences, in coronal, axial and sagittal planes. The follow alterations were evaluated: dislocation, degenerative disease of articular surface, osteochondritis, discal perforation, and retrodiscal lesions. Results: 175 of all showed pathologic alterations in IRM examination. The other 40 patients were excluded due to present a normal (MRI) study. The patients were 146 females and 29 men. The most common dislocation site was the anterior. Performance of the IRM was useful in all the cases to demonstrate degenerative changes in the temporomandibular joint (TMJ). And was a very precise relationship between the dislocation and degenerative disease of the joint. Conclusion: the female patient is the most frequently affected by temporomandibular joint pathology. The IRM is the selection method to study the TMJ. The degenerative changes are responsible for joint dislocation without reduction. (author) [es

    Temporomandibular joint (TMJ) is a synovial joint that represents the junction of mandible with skull. TMJ and mastication muscles are affected by temporomandibular disorders (TMDs). During the last two decades the advances in imaging diagnostic of TMJ have greatly contributed to the assessment of the TMJ disorders. Labelled leukocytes with technetium- 99m hexamethyl propylene amine oxime ({sup 99m}Tc-HMPAO) represent an efficient method that generates images based in physiological and/or biochemical changes related to inflammation. The aim of this study was to investigate the potential usefulness of technetium-99m labelled leukocytes scintigraphy in the diagnosis of TMJ inflammatory process applying a rabbit TMJ arthritis model. Arthritis was induced unilaterally with an intra-articular injection of ovalbumin in left ATM. On the contra-lateral side, the same dose of saline was injected. After five days, leukocytes were labeled with HMPAO and {sup 99m}Tc-HMPAO TMJ scintigraphic images were made. After twelve days a computed tomography was realized. Scintigraphic images obtained five days after induction of TMJ inflammation showed the localization of inflammatory process. The results were expressed as cpm of activity found in left ATM and contra-lateral side. Significant differences of activity were found between inflamed articulation and contra-lateral side (P = 0,0073). In conclusion, the method of leukocytes labeled with {sup 99m}Tc showed to be sensitive in detection of inflammatory disorders of TMJ and can be of great value in early diagnostic of these disorders.

    Tooth grinding and tooth clenching are unvoluntary mainly nocturnal habits that result in an hypertrophy of masseter and temporalis muscles with an unbalance between opening and closing muscles of the jaw and lead to an alteration of mandibular condyles movements and to hyper pressure in the temporo-mandibular joints (TMJ) which can generate severe pain. Intra muscular injections of botulinum toxin permit to restablish the balance between closing and opening muscles, to relieve pain, to treat masseteric hypertrophy with improvement of face outline and to recover a normal cinetic of temporo-mandibular joints. Moreover, botulinum toxin injections permit to quit habits of tooth grinding and clenching and one single session of injections is curative for 2/3 of the patients. There are no side effects apart from slight diffusion to superficial muscles of the face resulting in a "fixed" smile for about 6 to 8 weeks. So injections of botulinum toxin in masseter and temporalis muscles are an efficient treatment of bruxism and TMJ dysfunction, cheap with no lasting side effect.

    The aim of this study was to compare and evaluate the efficacy of different concentrations of dextrose prolotherapy for the treatment of temporomandibular joint (TMJ) hypermobility. A prospective, randomized clinical trial including patients with subluxation or dislocation was performed. The study comprised 40 patients. Patients were randomly divided into 4 groups: control group, 10% dextrose, 20% dextrose, and 30% dextrose group. Patients in all groups received injections into 4 different areas of each TMJ in 4 sessions at monthly intervals. Visual analog scale of TMJ pain intensity, maximum mouth opening (MMO), joint sounds, and frequency of luxations were recorded preoperatively and postoperatively after 1 month of last injection. The collected data were then statistically analyzed. Each group showed postoperatively significant improvement in TMJ pain, significant decrease in both MMO and joint sound. Besides that, TMJ locking was not observed in any patient during the follow-up period. There were no statistically significant differences throughout the study intervals between the groups. It was concluded that there was no significant difference between control group and dextrose groups and there is no superiority of any concentration of dextrose over the others in TMJ prolotherapy, and all treatment procedures were efficient in improvement of clinical symptoms related to TMJ hypermobility. If dextrose is used as a proliferant, it can be said that 10% dextrose can be sufficient in TMJ hypermobility treatment.

    Because the concept of whiplash as a causative factor for temporomandibular disorders (TMD) is highly controversial, we decided to do a retrospective analysis of patients treated in our office who had sustained whiplash injuries and were treated for cervical and temporomandibular disorders. The records of 300 patients with TMD preceded by a motor vehicle accident were examined retrospectively. The most common presenting symptoms, in order, were: jaw pain, neck pain, post-traumatic headache, jaw fatigue, and severe temporomandibular joint (TMJ) clicking. The most common TMD diagnoses were: masseter trigger points, closing jaw muscle hyperactivity, TMJ synovitis, opening jaw muscle hyperactivity, and advanced TMJ disk derangement. Based primarily on the physical examination, we concluded that the TMJ and surrounding musculature should be examined similarly to other joints, with no preconceived notion that TMD pathology after whiplash is unlikely.

    Full Text Available Objective: To evaluate the association between exostosis and / or torus along with the variables: sex, age, ethnic aspects, anatomic site and temporomandibular joint dysfunction (TMD. Methods: This was a retrospective and serial case study. The sample consisted of 75 patients, of both genders, aged between the 1st and 10th life decades, sorted from the Center of Oral facial Pain of Pernambuco Dentistry School at the State University of Pernambuco (CDO-FOP-UPE. The data were obtained by means of patients’ interview, complemented by analyses of clinical records, besides intraoral examination for the identification, description and classification of the exostosis and/or palatal and/or mandibular torus. The descriptive statistical analyses was accomplished considering anthropometric and demographic data of the patients, applying Pearson’s chi-square test and Fisher’s exact test (p>5. Results: The torus was present in 20.0% of the cases, of which 60.0% were palatal torus. The majority of the cases occurred in male patients (25.0%, brown in color (24.3% and at the 5th decade of life (23.1%, with no association between its presence and the sex, age or race. It was observed that the displacement of the disc with reduction was the type of intra-capsular TMD most related to these alterations. Conclusion: In the studied sample, the presence of torus was registered in 20.0% of the studied subjects, although there was no statistically significant association between the presence of exostosis and the analyzed variables – sex, race and age. The displacement of the disc with reduction was the temporomandibular joint dysfunction most associated to the presence of torus.

    Objective of the study was to evaluate the clinical status of the masticatory system in young adults with full permanent dentition and no stomatognathic system complaints. The study involved 186 randomly selected people with full dental arches with normal occlusal conditions corresponding to Angle's Class I aged 18 - 21 years with an average age of 19 years. Subjects were clinically examined and temporomandibular joint (TMJ) vibrations were recorded during open-wide and close movements using BioJVA. Then, patients were categorized into groups according to Piper's classification system. The TMJs of the subjects were categorized according to the values of the vibration energy and the Piper protocol. This detected 33.4% of the joints with loosened ligaments, subluxation in 8.28%, initial signs of disc dysfunction in 5.08% and disc displacement without locking in 1.6 %. Median frequency differed significantly (p vibrations. However, a subset of people manifested higher vibrations that may indicate an early stage of TMJ dysfunction. Median Frequency was an important parameter for detecting initial symptoms of TMJ dysfunction. Peak Frequency was an important characteristic parameter for detecting TMJ subluxation.

    Full Text Available We present a case involving a late diagnosis of chondroblastoma of the temporal skull base involving the temporomandibular joint (TMJ. Following an initial misdiagnosis and unsuccessful treatment over a period of 5 years, the patient was referred to our department for further evaluation and possible surgical intervention for occlusal abnormalities, trismus, clicking of the TMJ, and hearing impairment. Based on preoperative immunochemical studies showing positive reaction of multinucleated giant cells for S-100 protein, the final diagnosis was chondroblastoma. The surgical approach – postauricular incision and total parotidectomy, with complete removal of the temporal bone, including the TMJ via the extended middle fossa – was successful in preserving facial nerves and diminishing clinical manifestations. This study highlights a misdiagnosed case in an effort to underline the importance of medical examinations and accurate differential diagnosis in cases involving any tumor mass in the temporal bone.

    This article describes the results of treating temporomandibular joint (TMJ) articular disc perforation and advanced chondromalacia arthroscopically by the use of discoplasty and abrasion arthroplasty. Forty-four joints were treated in 25 patients (23 females and 2 males). Twenty-nine disc perforations were present, 24 joints had grade III chondromalacia (fibrillated cartilage), and 14 joints had grade IV chondromalacia (exposed bone). Surgical procedures included 14 abrasion arthroplasties and 24 motorized shavings or holmium laser vaporizations. Holmium laser discoplasty with mobilization was used in 29 joints. Patients were followed-up for an average of 40.8 months (11 to 74 months). Preoperative pain on the visual analog scale (VAS) (1 to 10 cm) ranged from 5 to 10 cm, with an average of 7.4 cm. Postoperatively, nine patients had no pain and 16 patients had an average VAS of 2.7 cm (range, 1 to 5 cm). Preoperatively, 30 joints had clicking, and 14 joints had crepitation. Postoperatively, 25 joints had no noise, 12 joints had slight intermittent clicking, and seven joints had crepitation. The preoperative range of motion averaged 29.7 mm. Postoperatively, the range of motion averaged 37.7 mm (range, 33 to 42 mm). All patients could masticate a regular diet except hard food after an average of 40.8 months (11 to 74 months). These findings seem to justify the arthroscopic surgical procedures of discoplasty for disc perforations, motorized shaving, or holmium laser vaporization of grade III chondromalacia, and abrasion arthroplasty for bone exposure. The results also question the need for discectomy in the treatment of disc perforation.

    This study was performed to compare the condylar position in patients with temporomandibular joint disorders (TMDs) and a normal group by using cone-beam computed tomography (CBCT). In the TMD group, 25 patients (5 men and 20 women) were randomly selected among the ones suffering from TMD according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). The control group consisted of 25 patients (8 men and 17 women) with normal temporomandibular joints (TMJs) who were referred to the radiology department in order to undergo CBCT scanning for implant treatment in the posterior maxilla. Linear measurements from the superior, anterior, and posterior joint spaces between the condyle and glenoid fossa were made through defined landmarks in the sagittal view. The inclination of articular eminence was also determined. The mean anterior joint space was 2.3 mm in the normal group and 2.8 mm in the TMD group, respectively. The results showed that there was a significant correlation between the superior and posterior joint spaces in both the normal and TMD groups, but it was only in the TMD group that the correlation coefficient among the dimensions of anterior and superior spaces was significant. There was a significant correlation between the inclination of articular eminence and the size of the superior and posterior spaces in the normal group. The average dimension of the anterior joint space was different between the two groups. CBCT could be considered a useful diagnostic imaging modality for TMD patients.

    2008-09-01

    We present a case of spontaneous subluxation of the Temporo-mandibular joint (TMJ) induced by succinylcholine, to compare our experience with previous cases reported in the literature, and to review the pathophysiology, preoperative screening, and intraoperative management of TMJ instability. A 39-yr-old female with primary hyperparathyroidism and a normal airway examination presented for elective parathyroidectomy. Following induction of anesthesia and the administration of succinylcholine prior to jaw manipulation, her mouth could not be opened, and we suspected spontaneous subluxation of the TMJ. We secured the airway with the use of a Trachlight and, subsequently, reduced the joint. Postoperatively, a history of mild TMJ-related symptoms was elicited. Instability of the TMJ is not uncommon, and has several implications for airway management, highlighting the importance of preoperative screening. Limited mouth opening, due to spontaneous subluxation of the TMJ following succinylcholine-induced muscle relaxation in the absence of airway manipulation, has only twice been reported in the literature. This report highlights how tracheal intubation may be accomplished using the Trachlight, in order to secure the airway prior to reduction of the subluxed joint.

    Temporomandibular disorders (TMD) are defined as clinical conditions that involve the masticatory muscles, temporomandibular joint (TMJ) or both. The aim of this study was to evaluate serum 17β-oestradiol and progesterone levels in menstruating women affected by internal derangement of the TMJ. A total of 142 women (mean age 30·2 ± 6·7) who referred to medical diagnostic laboratory of Iranian Academic Centre for Education, Culture and Research (ACECR), Mashhad Branch, were enrolled during 2007 and 2008. Forty-seven individuals had disc displacement with reduction (Group IIa) according to Research Diagnostic Criteria (RDC)/TMD Axis I diagnosis. Radioimmunoassay was used for the detection of serum 17β-oestradiol and progesterone levels in all 142 subjects. The mean progesterone level was significantly higher in control group (11·6 ± 10·4 ng mL(-1) ) compared to women with TMD (8·4 ± 6·8 ng mL(-1) , P = 0·03). No significant difference was found in two groups regarding 17β-oestradiol level. Lower progesterone level in women with TMD can suggest the more important role of this hormone in the development of the disorder. © 2013 John Wiley & Sons Ltd.

    We compared the diagnostic reliability of 3.0-T magnetic resonance imaging (MRI) for detection of osseous abnormalities of the temporomandibular joint (TMJ) with that of the gold standard, cone-beam computed tomography (CBCT). Fifty-six TMJs were imaged with CBCT and MRI, and images of condyles and fossae were independently assessed for the presence of osseous abnormalities. The accuracy, sensitivity, and specificity of 3.0-T MRI were 0.88, 1.0, and 0.73, respectively, in condyle evaluation and 0.91, 0.75, and 0.95 in fossa evaluation. The McNemar test showed no significant difference (P > 0.05) between MRI and CBCT in the evaluation of osseous abnormalities in condyles and fossae. The present results indicate that 3.0-T MRI is equal to CBCT in the diagnostic evaluation of osseous abnormalities of the mandibular condyle.

    Full Text Available OBJECTIVE: This study aimed to evaluate the possibility of any correlation between disc displacement and parameters used for evaluation of skull positioning in relation to the cervical spine: craniocervical angle, suboccipital space between C0-C1, cervical curvature and position of the hyoid bone in individuals with and without symptoms of temporomandibular dysfunction. MATERIAL AND METHODS: The patients were evaluated following the guidelines set forth by RDC/TMD. Evaluation was performed by magnetic resonance imaging for establishment of disc positioning in the temporomandibular joints (TMJs of 30 volunteer patients without temporomandibular dysfunction symptoms and 30 patients with symptoms. Evaluation of skull positioning in relation to the cervical spine was performed on lateral cephalograms achieved with the individual in natural head position. Data were submitted to statistical analysis by Fisher's exact test at 5% significance level. To measure the degree of reproducibility/agreements between surveys, the kappa (K statistics was used. RESULTS: Significant differences were observed between C0-C1 measurement for both symptomatic (p=0.04 and asymptomatic (p=0.02. No statistical differences were observed regarding craniocervical angle, C1-C2 and hyoid bone position in relation to the TMJs with and without disc displacement. Although statistically significant difference was found in the C0-C1 space, no association between these and internal temporomandibular joint disorder can be considered. CONCLUSIONS: Based on the results observed in this study, no direct relationship could be determined between the presence of disc displacement and the variables assessed.

La existencia de variados enfoques terapéuticos para los trastornos temporomandibulares queda justificada por la multifactorialidad de la etiología; las 2 alternativas más utilizadas son las férulas oclusales y el tallado selectivo. Se prefiere la fisioterapia a la quimioterapia, como coadyuvante terapéutica de los trastornos temporomandibulares, ya que disminuye el peligro de producir reacciones adversas. Solo se indicará el tratamiento quirúrgico cuando han fracasado los métodos conservadores.A literature review was made to provide updated information on the different therapeutic alternatives at the disposal of dental professionals for the treatment of termporomandibular disorders aimed at relieving pain and re-establish the functioning of the joint. However, it is necessary to firstly make a good diagnosis and then detect the causative factors, emphasizing that stress is a key element to be taken into consideration. The existence of various therapeutical approaches for temporomandibular disorders is due to the multiple factors present in the etiology; the two most used alternatives are occlusal splints and selective carving. Physiotherapy is prefered over chemotherapy, as therapeutic coadjuvant for temporomandibular disorders, because likely occurence of adverse reaction decreases. The surgical treatment will be advised only in the event of failure of standard methods.

    Sagittal and coronal images of the bilateral temporomandibular joint (TMJ) simultaneously have been obtained to evaluate displacement of the meniscus in nine patients with TMJ clicking using a 0.2-Tesla permanent magnetic unit. The obtained images were displayed in closed loop cine fashion and recorded on videotapes. Anterior displacement of meniscus was seen on sagittal images in 5 of 9 paients. In the other four patients, no anterior displacement was observed, but in three of them, medial and lateral displacement on coronal images were shown in the closed position. Even using the 0.2-Tesla unit, simultaneous pseudodynamic display of the bilateral TMJ in sagittal and coronal planes was useful for evaluating internal derangement of the TMJ. This technique not only saves time but provides accurate evaluation of meniscal position and motion. (H.O.)

    jaw dysfunction and its association with the level of temporomandibular symptoms. METHODS: 28 women, with ages between 19 and 56 years, who had temporomandibular jaw dysfunction and had not been submitted to a preview treatment, made part of this study. All subjects answered a questionnaire written by Fonseca et al (1994 entitled Anamnesic Index, that enabled us to classify temporomandibular jaw symptoms level and also to check the symptoms of this oral parafunction behavioral bruxism; the subjects were submitted an odontological evaluation, that was composed by an exam of masticatory muscles, though the digital touch in the oral and extra-oral muscles, examination in the temporomandibular joint and a teeth examination. The results were analyzed in a descriptive form, and in order to check the relationship between the severity level of temporomandibular dysfunction with the bruxism occurrence Independent Square-Qui test and the Fisher test were used with a statistic significance of 5%. RESULTS: it was observed the parafuntional habit was presented in 50% of the cases with temporomandibular dysfunction. It wasn't possible a relationship between bruxism and the level of symptoms in temporomandibular jaw dysfunction, by Anamnesic Index. CONCLUSION: the results of this study suggest that subjects with symptoms of temporomandibular jaw dysfunction must be asked and evaluated about bruxism, regardless of the level of temporomandibular dysfunction. Besides this, it is important to investigate the diagnosis and the treatment of bruxism also in patients without temporomandibular jaw dysfunction in order to prevent development of lesions in the temporomandibular joints and the other structures of the stomatognatic system.

    Full Text Available Temporomandibular joint (TMJ ankylosis as a complication of neonatal septic arthritis is rarely reported in the literature. We report two clinical cases of unilateral TMJ ankylosis occurring in paediatric patients subsequent to neonatal septic arthritis. The first case was a 15-month-old male infant who presented to the Sultan Qaboos University Hospital, Muscat, Oman, in May 2010. According to the published English scientific literature, he is the youngest person yet to be diagnosed with this condition. The second case was a five-year-old female who presented to the Al-Nahda Hospital, Muscat, Oman, in October 2011. Both cases presented with facial asymmetry and trismus. They subsequently underwent gap arthroplasty and interpositional temporalis muscle and fascia grafts which resulted in an immediate improvement in mouth opening. Postoperatively, the patients underwent active jaw physiotherapy which was initially successful. Both patients were followed up for a minimum of two years following their surgeries.

    Full Text Available Objective: Chronic periodontitis is a world-wide infectious and inflammatory disease and may have a relationship with other inflammatory diseases such as fibromyalgia syndrome (FMS. The aim of this study was to determine whether the prevalence of periodontitis is increased in individuals with FMS or not. Materials and Methods: Sixty-four patients with FMS and 70 systemically healthy individuals were included in the present study. Fibromyalgia patients did not have any other systemically disease. All subjects had at least 20 functioning teeth and underwent detailed oral and radiographic examination, in addition, bruxism and temporomandibular joint (TMJ examinations were performed. All clinical attachment levels, plaque and gingival indices were recorded. Results: Fibromyalgia patients tend to have higher gingival index scores than healthy individuals. There was a significant difference in the presence of bruxism between the study groups (p0.05. Conclusion: We found that the prevalence of periodontitis was not changed in FMS patients but was increased in healthy subjects above age 45.

    The objectives were to find specific factors that are mathematically distinct between the chewing timings, movement pattern shapes, variability, and movement velocities of: (1) normal asymptomatic subjects and (2) a group of subjects with verified temporomandibular joint (TMJ) internal derangements. Left- and right-sided chewing movement recordings of 28 subjects (34.5 ± 14.0 years) were randomly selected from a large database of patients exhibiting verified unilateral or bilateral TMJ internal derangements. The chewing movements of an age- and gender-matched control group of 20 asymptomatic subjects (32.5 ± 11.6 years, P>0.60) with verified normal TMJ function were also recorded. Means and standard deviations of the opening, closing, turning point, terminal chewing position, and velocity patterns were calculated. A two-tailed Student's t-test with unequal variances was used to compare the parameters between the two groups (alpha = 0.05). The dysfunctional group functioned significantly slower and with greater variability than the control group. The vertical dimension was consistently smaller in the dysfunctional group (Pchewing position was significantly less precise in the dysfunctional group (vertical: Pchewing patterns than the control group. The functional pattern of mastication appears to be significantly altered in the presence of an internal derangement of the TMJ.

    The histological fate of abdominal dermis-fat grafts implanted into the temporomandibular joint (TMJ) following condylectomy was studied. 21 rabbits underwent left TMJ discectomies and condylectomies; 6 were controls (Group A; no graft used); 15 (Group B) had autogenous abdominal grafts transplanted into the left TMJ. Animals were killed after 4, 12 and 20 weeks. Specimens of the TMJ were histologically and histomorphometrically evaluated. At 4 weeks, fat necrosis was clear in all specimens. The dermis component survived and formed cysts with no necrosis. By 12 weeks, viable fat deposits appeared with no evidence of necrotic fat. At 20 weeks, large amounts of viable fat were present in Group B specimens. Group A had no fat, although the missing condyles regenerated. In the presence of viable fat, Group B showed little condyle regeneration 20 weeks after condylectomy. Non-vascularised fat grafts do not survive transplantation, but stimulate neoadipogenesis. The fate of the dermis component of the graft is independent of the fat component. Fat in the joint space disrupts the regeneration of a new condylar head. Neoadipogensis inhibits growth of new bone and cartilage. This has clinical implications for TMJ ankylosis management and preventing heterotopic bone formation around prosthetic joints.

    Objective: Although it is a rare condition, pigmented villonodular synovitis (PVNS) may involve temporomandibular joint (TMJ). The purpose of this study was to describe magnetic resonance (MR) findings of PVNS of the TMJ. Methods and material: Between April 1992 and August 2000, four patients (two men and two women, 22-58-year-old) who had histologically proven diagnoses of PVNS in their TMJ were found in our institution. Their MR findings were reviewed retrospectively, and were correlated with pathologic findings. Results: In all four patients, MR images invariably showed profound hypointensity on both T1- and T2-weighted sequences. This finding was seen diffusely and homogeneously throughout the lesion, and was considered to be due to paramagnetic effect attributed to heavy hemosiderin pigmentation, which was revealed by histopathological examination. MR images also showed aggressive nature of the lesions with adjacent skull base destruction and intracranial extension in two of them. Conclusion: As is the case in the other anatomic site, PVNS of the TMJ can be confidently diagnosed on MR imaging on the basis of the presence of hemosiderin. MR imaging also plays a pivotal role in surgical planning by precise and detailed localization of the lesion.

    The purpose of this case series study was to evaluate the advantages and disadvantages of using local anesthesia and conscious sedation (CS) rather than general anesthesia (GA) for performing functional surgery on patients suffering from temporomandibular joint (TMJ) closed lock, using the eminectomy procedure. Performing this procedure using CS allows functional assessment of the TMJ meniscus at the time of surgery. The objectives of this study were to determine if this surgery is possible under CS, to determine the benefits of being able to see the meniscus in action, and to investigate the patients\\' acceptability for this form of anesthesia.

    The articulation of the temporomandibular joint (TMJ) is composed of the temporal bone dorsally, the mandibular condyle ventrally and a fibrous articular disc. The TMJ disc plays an essential role in distributing load between the two articular surfaces. Degeneration of the disc in the presence of joint pathology has been shown in man; however, TMJ pathology has not been documented previously in tigers (Panthera tigris). The mandibular condyle and TMJ disc of a Bengal tiger (P. tigris tigris) and a Siberian tiger (P. tigris altaica) were evaluated grossly and the TMJ disc was characterized biochemically and mechanically. Characterization of the TMJ disc verified region- and direction-dependent biochemical and mechanical properties, reflective of the functional demands on the joint. Degenerative joint disease was observed in both cases and this was more severe in the Siberian tiger. Simultaneous evaluation of joint pathology, biochemical composition and mechanical properties of the TMJ disc revealed a loss in functional properties (tensile anisotropy) of the disc as joint pathology advanced from moderate to severe. TMJ degeneration may compromise the ability of the animal to eat and thrive and may be a factor contributing to the endangered status of these species. Copyright © 2013 Elsevier Ltd.

    A new cine-technique in a prospective study using rapid gradient echo sequences was evaluated for the MRT investigation of the temporo-mandibular joint. A newly developed hydraulic apparatus was used to produce progressive opening of the jaw and MRT appearances were recorded during predetermined points of mandibular movement. The investigation included 16 normals and 34 patients. A modified gradient echo sequence was combined with an optimised surface coil or a special double coil and this provided good spatial resolution of the articular disc and of the muscular and bony structure. Amongst the abnormal findings were luxation of the disc (15 cases), tears in the disc (5 cases), late effects of internal derangements (12 cases) and condylar hypermobility (7 cases). The new cine-technique provides specific images in any chosen position of the mandible depending on the clinical disability of the patient. (orig.) [de

    Full Text Available Abstract This review explores the aetiology of temporomandibular disorders and discusses the controversies in variable treatment modalities. Pathologies of the temporomandibular joint (TMJ and its' associated muscles of mastication are jointly termed temporomandibular disorders (TMDs. TMDs present with a variety of symptoms which include pain in the joint and its surrounding area, jaw clicking, limited jaw opening and headaches. It is mainly reported by middle aged females who tend to recognize the symptoms more readily than males and therefore more commonly seek professional help. Several aetiological factors have been acknowledged including local trauma, bruxism, malocclusion, stress and psychiatric illnesses. The Research Diagnostic Criteria of the Temporomandibular Disorders (RDC/TMD is advanced to other criteria as it takes into consideration the socio-psychological status of the patient. Several treatment modalities have been recommended including homecare practices, splint therapy, occlusal adjustment, analgesics and the use of psychotropic medication; as well as surgery, supplementary therapy and cognitive behavioural therapy. Although splint therapy and occlusal adjustment have been extensively used, there is no evidence to suggest that they can be curative; a number of evidence-based trials have concluded that these appliances should not be suggested as part of the routine care. Surgery, except in very rare cases, is discouraged since it is the most invasive alternative; recent studies have shown healthier outcome with cognitive behavioural therapy.

    The purpose of this study was to compare changes in temporomandibular joint (TMJ) and ramus morphology between class II and III cases before and after sagittal split ramus osteotomy (SSRO) and Le Fort I osteotomy. The subjects were 39 patients (78 sides) who underwent bi-maxillary surgery. They consisted of 2 groups (18 class II cases and 21 class III cases), and were selected randomly from among patients who underwent surgery between 2012 and 2016. The TMJ disc tissue and joint effusion were assessed by magnetic resonance imaging (MRI) and the TMJ space, condylar height, ramus height, ramus inclination and condylar square were assessed by computed tomography (CT), pre- and post-operatively. The number of joints with anterior disc displacement in class II was significantly higher than that in class III (p bi-maxillary surgery. The findings of the numerical analysis also demonstrated that reduction of condylar volume occurred frequently in class II, although TMJ disc position classification did not change significantly, as previously reported.

    To compare Computed Tomography (CT) and Magnetic Resonance (MR) features and their diagnostic potential in the assessment of Synovial Chondromatosis (SC) of the Temporo-Mandibular Joint (TMJ). Eight patients with symptoms and signs compatible with dysfunctional disorders of the TMJ underwent CT and MR scan. We considered the following parameters: soft tissue involvement (disk included), osteostructural alterations of the joints, loose bodies and intra-articular fluid. These parameters were evaluated separately by two radiologists with a "double blinded method" and then, after agreement, definitive assessment of the parameters was given. CT and MR findings were compared. Histopathological results showed metaplastic synovia in all patients and therefore confirmed diagnosis of SC. MR resulted better than CT in the evaluation of all parameters except the osteostructural alterations of the joints, estimated with more accuracy by CT scan. CT scan is excellent to define bony surfaces of the articular joints and flogistic tissue but it fails in the detection of loose bodies when these are not yet calcified. MR scan therefore is the gold standard when SC is suspected since it can visualize loose bodies at early stage and also evaluate disk condition and eventual extra-articular tissues involvement. The use of T2-weighted images and contrast medium allows identifying intra-articular fluid, estimating its entity and discriminating from sinovial tissue. Copyright © 2009 Elsevier Ireland Ltd.

    The present study was conducted to investigate the relationship between magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) and clinical findings of patients having symptoms of temporomandibular disorders, and to consider the possibility to grasp the internal derangement of the TMJ from clinical findings. Subjects were 80 patients who visited to ask orthodontic treatment 16 males and 64 females. The average age was 22 years and 4 months. We performed a investigation of both their previous and present illness. In addition, to decide the correct condition concerning the internal derangement of the TMJ, patients were given MRI examinations (G. E. medical system Signa 1.5 Tesla) before orthodontic treatment. Results were as follows: The three symptoms of temporomandibular disorders-noise, pain, and abnormal mandibular movement, were not related to constant disk displacement. It seemed difficult to infer and obtain the diagnosis of the condition of internal derangement of the TMJ only from clinical findings. In a dental clinics having no medical imaging instrument such as MRI, it was, however, considered that the following items will make it possible to define the condition of internal derangements of the TMJ from clinical findings. As to respects concerning clinical findings, it is necessary to consider the previous illness as well as present illness. TMJ noise indicates a higher relationship to the disk displacement in MRI findings. The temporomandibular joint with plural symptoms indicated a higher incidence of disk displacement examined by MR Imaging than that with a single symptom. (author)

    The diagnosis and appropriate management of temporo-mandibular disorders (TMDs) remains controversial. Current scientific evidence highlights the importance of psychosocial factors in sufferers and the reducing emphasis on occlusal or dental/prosthetic factors. This paper describes the findings of a survey of 211 patients reporting pain from their temporo-mandibular joint area and associated structures. This article offers busy primary dental care practitioners a cost effective questionnaire for obtaining relevant information from patients about the history of their condition and highlights what patients hope to achieve through the management of their disorder. It also emphasises the importance of communicating effectively with patients and offers practical tips for the management of TMDs in primary care.

    To examine the occurrence of intermittent lock, we investigated the correlation between the frequency of intermittent lock of the temporomandibular joint and magnetic resonance imaging (MRI) findings. The subjects consisted of 25 patients (25 joints) with unilateral intermittent lock who were treated from April 1994 through March 2000 at our department. MRI examination of the joint was performed on the affected side. We divided the patients into two groups: a high-frequency group consisting of 15 patients who had symptoms of intermittent lock every day and a low-frequency group consisting of 10 patients who did not have symptoms every day. The results showed no statistical difference between the two groups in clinical findings such as age, sex, clicking side of the joint, duration of intermittent lock, method of unlocking, muscle pain on palpation, degree of maximal mouth opening, distance between the maxillary and mandibular tooth midline, or the degree of overbite and overjet. However, the two groups differed significantly in the degree of anterior disc displacement as assessed by MRI. (author)

    To test in vitro and in vivo the reliability and accuracy of a new algometer, the pressure algometer for palpation (PAP), for measuring pressure pain thresholds (PPTs) and to compare its features with those of a commercially available pressure algometer. For in vitro accuracy testing, 6 repeated measurements were made at 8 defined test weights from 0.5 to 5 lb. In vivo validity testing compared the PAP to a standard instrument, the hand-held Somedic algometer, at 16 sites including the masticatory muscles, the temporomandibular joints, and the frontalis (as the control site) in 15 temporomandibular disorder (TMD) cases and 15 controls. Intraexaminer reliability was also assessed for both algometers. In vitro reliability was high, with coefficients of variation of test weights at r = .99 (P algometer. PPT values correlated moderately between the 2 devices (r ranged from 0.38 to 0.66; P algometers (P algometer showed high reliability. Concurrent validity was demonstrated by statistically significant correlations between the devices. Both showed equally high capacity for differentiating TMD cases from controls. The PAP yielded significantly higher PPTs than the Somedic algometer.

    The urokinase plasminogen activator system is believed to play an important role in degradation of the extracellular matrix associated with cartilage and bone destruction; however its precise roles in temporomandibular disorders have not yet been clarified. The aims of this study were to investigate the gene expression of fibrinolytic factors urokinase plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) in the articular cartilage of rabbit temporomandibular joint (TMJ) with disc displacement (DD) and to probe the relationship between fibrinolytic activity and cartilage remodeling. Disc displacement of right joints was performed in 36 of 78 rabbits under investigation. The animals were sacrificed at 4 days and 1, 2, 4, 8 and 12 weeks after surgery, respectively. The right joints of these animals were harvested and processed for the examination of mRNA expression of uPA and PAI-1 in articular cartilage using in situ hybridization techniques. The expression of uPA and PAI-1 was co-expressed weakly in the chondrocytes from transitive zone to hypertrophic zone and mineralized zone, while no hybridizing signals were shown in proliferative zone and superficial zone in control rabbits. The most striking was the up-regulation of uPA and PAI-1 mRNA in 4-day rabbits postoperatively at the onset of cartilage degeneration. The strongest hybridizing signals for uPA and PAI-1 were seen in 2-week rabbits postoperatively. After 2 weeks, the expression of uPA and PAI-1 began to decrease and reached nearly normal level at 12 weeks. The expression of the uPA/PAI-1 system coincides with the pathological changes in condylar cartilage after DD. The uPA/PAI-1 system may be one of the essential mediators in articular cartilage remodeling.

    This study investigated the prevalence of Temporomandibular Disorders (TMD) in the elderly and its association with palpation of the temporomandibular joint (TMJ), masticatory and cervical muscles as well as the presence of headache and joint noises. The sample consisted of 200 elderly of both genders (mean age: 69.2±5.7 years). The clinical evaluation of TMD signs and symptoms was divided into three stages: an anamnestic questionnaire, a TMJ evaluation, and a muscular examination. The results were analyzed through descriptive statistics as well as using χ2 and the tendency tests. The presence of TMD was observed in 61% of the sample (mild: 43.5%, moderate: 13%, severe: 4.5%). A significantly greater prevalence of TMD was found for females (72.4%) compared with that for men (41.1%) (pheadaches and the presence of TMD (p=0.0001). The association between the presence of joint noises and sensitivity to TMJ palpation was not significant. The elderly presented high TMD prevalence, mostly in females, with mild severity and related to TMJ and masticatory/cervical muscles palpation. Thus, the accomplishment of a detailed clinical examination to investigate the presence of such disorders is essential and it must not be neglected during the treatment of elderly patients.

    Full Text Available Background: Patient suffering from occlusal abnormality is usually detected months or even years when the acute patient visits a dentist, and generally the patient does not receive direct treatment upon his complaints since minimum information is available on this type of treatment. In general, the dentist provides medication only or conducts incorrect selective grinding where in fact, the patient does not feel better from the previous conditions. Purpose: The objective of this study is to discuss the treatment on the dysfunctional temporomandibular joint followed by orofacial pain caused by occlusal disorder using occlusal splint. Case: In this case, a forty three years old male having trouble with the joint on the left jaw followed by orofacial pain caused by occlusal disorder. Case Management: Initial treatment with occlusal splint makes the patient comfortable and recovers from his complaints since the patient could restructure the chewing muscles. This treatment will be more successful if the dentist has the knowledge to use and choose occlusal splint method properly. Occlusal Splint could be used as a supporting therapy and consideration as one of the therapies to avoid the unwanted side effects. The use of occlusal splint is meant as an alternative of the main therapy in overcoming the problem of occlusal splint. Conclusion: Finally, therapy with occlusal splint is very effective as an alternative treatment to handle the dysfunction of temporomandibular joint caused by occlusion.

    In human medicine, magnetic resonance imaging (MRI) is considered the 'gold standard' imaging procedure to assess the temporomandibular joint (TMJ). However, there is no information regarding MRI evaluation of equine TMJ. To describe the normal sectional MRI anatomy of equine TMJ by using frozen and plastinated anatomical sections as reference; and determine the best imaging planes and sequences to visualise TMJ components. TMJs from 6 Spanish Purebred horse cadavers (4 immature and 2 mature) underwent MRI examination. Spin-echo T1-weighting (SE T1W), T2*W, fat-suppressed (FS) proton density-weighting (PDW) and fast spin-echo T2-weighting (FSE T2W) sequences were obtained in oblique sagittal, transverse and dorsal planes. Anatomical sections were procured on the same planes for a thorough interpretation. The oblique sagittal and transverse planes were the most informative anatomical planes. SE T1W images showed excellent spatial resolution and resulted in superior anatomic detail when comparing to other sequences. FSE T2W sequence provided an acceptable anatomical depiction but T2*W and fat-suppressed PDW demonstrated higher contrast in visualisation of the disc, synovial fluid, synovial pouches and articular cartilage. The SE T1W sequence in oblique sagittal and transverse plane should be the baseline to identify anatomy. The T2*W and fat-suppressed PDW sequences enhance the study of the articular cartilage and synovial pouches better than FSE T2W. The information provided in this paper should aid clinicians in the interpretation of MRI images of equine TMJ and assist in the early diagnosis of those problems that could not be diagnosed by other means.

    ABSTRACT The relationship between Temporomandibular Disorders (TMD) and malocclusion is an extremely critical issue in dentistry. Contrary to the old concept that malocclusion causes TMD, occlusal changes, especially those observed as sudden, may be secondary and reflect joint or muscle disorders due to the obvious connection between these structures and the dental occlusion. Objectives The aim of this article is to present the most commonly occlusal changes secondary to TMD. Methods The clinical presentation of these conditions is discussed. Details regarding diagnosis, treatment, and follow-up of patients presenting TMD prior or during treatment are also presented. Conclusions All plans for irreversible therapy should be preceded by a meticulous analysis of TMD signs and symptoms in such a way that patients are not submitted to irreversible treatment, based on an untrue occlusal relationship, secondary to articular and/or muscular disorders. When present, TMD symptoms must always be controlled to reestablish a “normal” occlusion and allow proper treatment strategy. PMID:27556214

    OBJECTIVES The aim of the current study is to collect scientific data on all branded hyaluronic acid (HA) products in Italy that are in use for intra-articular (IA) injection in osteoarthritis (OA) compared with that reported in the leaflet. METHODS An extensive literature research was performed for all articles reporting data on the IA use of HA in OA. Selected studies were taken into consideration only if they are related to products based on HAs that are currently marketed in Italy with the specific joint indication for IA use in patients affected by OA. RESULTS Sixty-two HA products are marketed in Italy: 30 products are indicated for the knee but only 8 were proved with some efficacy; 9 products were effective for the hip but only 6 had hip indication; 7 products proved to be effective for the shoulder but only 3 had the indication; 5 products proved effective for the ankle but only one had the indication; 6 products were effective for the temporomandibular joint but only 2 had the indication; only 2 proved effective for vertebral facet joints but only 1 had the indication; and 5 products proved effective for the carpometacarpal joint but only 2 had the indication. CONCLUSIONS There are only a few products with some evidences, while the majority of products remain without proof. Clinicians and regulators should request postmarketing studies from pharmaceuticals to corroborate with that reported in the leaflet and to gather more data, allowing the clinicians to choose the adequate product for the patient.

    Early treatment of temporomandibular joint (TMJ) arthritis is crucial in children with juvenile idiopathic arthritis (JIA) to prevent permanent functional impairment. As involvement of TMJs is often asymptomatic, contrast-enhanced MRI is regarded as the most sensitive noninvasive diagnostic tool. To evaluate the degree of contrast enhancement in TMJs of children and adolescents with JIA in comparison to normal controls from a previous study. Dynamic contrast-enhanced MRI of 50 children and adolescents with JIA (6.3 to 18 years of age; mean: 12 years) were retrospectively analysed. We assessed morphological abnormalities and postcontrast time-intensity curves of the soft joint tissue and the mandibular condyle. Ratios were calculated to quantify postcontrast signal intensities (SI) in relation to precontrast SI at initial (1 min postcontrast) and maximum (6 min postcontrast) increase. Time-intensity curves followed similar biphasic patterns in normal and pathological joints. In joints with morphological signs of arthritis, mean SI ratios were on average higher than in normal joints of the reference group, but ranges of values widely overlapped. Arthritis: mean initial increase of SI 62% (±2 S.D. 18-105%), mean maximum SI 106% higher than precontrast (±2 S.D. 46-166%). Normal: mean initial increase of SI 49% (±2 S.D. 14- 85%), mean maximum of SI 73% (±2 S.D. 23-123%). Given this considerable overlap of results in dynamic contrast-enhanced MRI, the degree of contrast enhancement alone did not allow differentiation between TMJs with and without signs of inflammation. Thickening of the soft joint tissue seems to remain the earliest sign to reliably indicate TMJ arthritis. (orig.)

    We investigated the ability to detect the articular disk and joint effusion of the temporomandibular joint (TMJ) of a method of dual echo volumetric isotropic turbo spin echo acquisition (DE-VISTA) additional fusion images (AFI). DE-VISTA was performed in the 26 TMJ of 13 volunteers and 26 TMJ of 13 patients. Two-dimensional (2D) dual echo turbo spin echo was performed in the 26 TMJ of 13 volunteers. On a workstation, we added proton density-weighted images (PDWI) and T 2 weighted images (T 2 WI) of the DE-VISTA per voxel to reconstruct DE-VISTA-AFI. Two radiologists reviewed these images visually and quantitatively. Visual evaluation of the articular disk was equivalent between DE-VISTA-AFI and 2D-PDWI. The sliding thin-slab multiplanar reformation (MPR) method of DE-VISTA-AFI could detect all articular disks. The ratio of contrast (CR) of adipose tissue by the articular disk to that of the articular disk itself was significantly higher in DE-VISTA-AFI than DE-VISTA-PDWI (P 2 WI but in only 3 of those joints in 2D-T 2 WI. The CR of joint effusion to adipose tissue on DE-VISTA-AFI did not differ significantly from that on DE-VISTA-PDWI. However, using DE-VISTA-T 2 WI in addition to DE-VISTA-PDWI, we could visually identify joint effusion on DE-VISTA-AFI that could not be identified on DE-VISTA-PDWI alone. DE-VISTA-AFI can depict the articular disk and a small amount of joint effusion by the required plane of MPR using the sliding thin-slab MPR method. (author)

    The aims of this study are to evaluate the prevalence of disorders of the lumbar region and the temporo-mandibular district co-morbidity in drivers and workers of the State Police employed for different office activities. The study population included 103 drivers as cases and 100 police officers as controls. The study was carried out through questionnaire and clinical evaluation of the spine and temporo-mandibular region. At clinical examination, the drivers were found to have a higher prevalence (p temporo-mandibular joint (TMJ), when compared with the controls. The results also showed a higher prevalence (p < 0.05) of co-morbidity in the two districts among the drivers, when compared with the controls. These results confirm that morbidity related to back and TMJ and increase in co-morbidity between the two districts are higher in professional drivers.

    The aim of the study was to define clinical predictors of magnetic resonance imaging (MRI) findings of temporomandibular joint (TMJ) involvement in juvenile idiopathic arthritis (JIA). Forty-six patients, aged 2.08-36.7 years, with JIA (oligoartitular 18, polyarticular 17, systemic type 11) were examined with standard plain and contrast-enhanced sequences. Of 88 TMJs examined, an abnormal condyle was observed in 32%, flattened articular eminence in 27%, flattened articular disk in 17%, intra-articular fluid in 10%, enhancing pannus in 45% and restricted condylar motion in 9%. Logistic regression analysis revealed that for abnormal condyle and flattened articular eminence, independent predictors were type of JIA (P 0.5 when the disease started before 4 years of age. In conclusion, the systemic type of JIA, young age at onset and long duration of activity are risk factors for TMJ damage. MRI of the TMJ should be performed in patients who are less than 4 years of age at the onset of JIA, and in those with the systemic type, whatever the age of onset. (orig.)

    An optimized examination protocol for the MRI evaluation of the temporomandibular joint (TMJ) is presented. The MRI protocol is based on an optimized coil technology, sequence design, and a programmed examination protocol for diagnostics of the TMJ. Depending on the clinical findings, MRI provides an all-in-one diagnostic protocol for the diagnosis of degenerative, inflammatory and tumorous lesions of the TMJ. MRI using an optimized examination protocol should become the primary examination protocol for diseases of the TMJ. (orig.)

    Full Text Available Osteoarthrosis (OA of temporomandibular joint (TMJ is a progressive degenerative disease, gradually affecting cartilage, synovial membrane and bone structures. OA of TMJ clinically manifests with joint noises, pain and restricted mouth opening. In late stages, it results in severe damage of TMJ structures and development of ankylosis. Osteoarthrosis is a multifactorial disease; the occurrence is associated with TMJ overloading. The cohort included 619 patients [538 women (87% and 81 men (13%, with average age 40.6 years (age range 8–89 years] with TMJ disorder, who were examined in the year 2014 in Department of Dental Medicine, First Faculty of Medicine, Charles University and General University Hospital in Prague, Czech Republic. The aim of this retrospective study was to analyse, if the lack of posterior teeth (supporting teeth zones is the main etiologic factor of osteoarthrosis of TMJ. Diagnosis of OA was established on the clinical signs and the panoramic X-ray signs. Simultaneously other etiologic factors of OA were assessed. The presence of OA changes on X-ray had 171 patients (i.e. 27.6% of the total number of 619. 17.5% from these patients with OA had defect in posterior dentition. Other aetiological factors (stress, skeletal or vertebrogenous disorders showed higher incidence of OA changes on X-ray. Defect of posterior dentition is not negligible, but it is not the main aetiological factor for osteoarthrosis of TMJ.

    To determine the effect of unilateral condylectomy on dental occlusion in cats. Twelve feline cadaver heads were randomly submitted to either a right or left unilateral condylectomy of the temporo-mandibular joint. The distance between the mandibular and maxillary canine tooth was measured before (B0) and after the unilateral condylectomy (P0). A right or left latero--lateral standardised force (4 N) was applied to the mandibular mentus area before and after the surgical procedure. These measurements were analysed with a linear model for repeated measures. The comparative analysis between pre- and postsurgical values indicated no significant variation in teeth displacement following condylectomy between B0 and P0 measurements. Statistically significant differences were detected after either left or right condylectomy with respect to all measurements after application of the standardised forces. Occlusion changes are significant when comparing bites before and after surgery. Unilateral condylectomy causes a significant increase in latero-lateral amplitude of jaw movement which might clinically affect feline dental occlusion. Clinical studies are required to determine the effect of unilateral condylectomies on mastication and dental occlusion in feline patients. © 2011 British Small Animal Veterinary Association.

    The purpose of this study was to elevate comparison of static MRI and pseudo-dynamic (cine) MRI in temporomandibular joint (TMJ) disorder patients. In this investigation, 33 patients with TMJ disorders were examined using both conventional static MRI and pseudo-dynamic MRI. Multiple spoiled gradient recalled acquisition in the steady state (SPGR) images were obtained when mouth opened and closed. Proton density weighted images were obtained at the closed and open mouth position in static MRI. Two oral and maxillofacial radiologists evaluated location of the articular disk, movement of condyle and bony change respectively and the posterior boundary of articular disk was obtained. No statistically significant difference was found in the observation of articular disk position, mandibular condylar movement and posterior boundary of articular disk using static MRI and pseudo-dynamic MRI (P>0.05). Statistically significant difference was noted in bony changes of condyle using static MRI and pseudo-dynamic MRI (P<0.05). This study showed that pseudo-dynamic MRI didn't make a difference in diagnosing internal derangement of TMJ in comparison with static MRI. But it was considered as an additional method to be supplemented in observing bony change

    Due to their nature as tissue composites, skeletal joints pose an additional challenge in terms of evaluating the functional significance of morphological variation in their bony and cartilaginous components in response to altered loading conditions. Arguably, this complexity requires more direct means of investigating joint plasticity and performance than typically employed to analyze macro- and micro-anatomical phenomena. To address a significant gap in our understanding of the plasticity of the mammalian temporomandibular joint (TMJ), we investigated the histology and mechanical properties of condylar articular cartilage in rabbits subjected to long-term variation in diet-induced masticatory stresses, specifically cyclical loading. Three cohorts of male weanlings were raised for six months on different diets until adulthood. Following euthanasia, the TMJ condyles on one side were dissected away, fixed, decalcified, dehydrated, embedded and sectioned. Safranin O staining was employed to identify variation in proteoglycan content, which in turn was used to predict patterns of articular cartilage stiffness in contralateral condylar specimens for each treatment group. Hematoxylin and eosin staining was used to quantify diet-induced changes in chondrocyte hypertrophy and cellularity. Mechanical tests document significant decreases in articular cartilage stiffness corresponding to patterns of extracellular matrix relative protein abundance in rabbits subjected to greater cyclical loading. This indicates that TMJs routinely subjected to higher masticatory stresses due to a challenging diet eventually develop postnatal decreases in the ability to counter compressive loads during postcanine biting and chewing. These findings provide novel information regarding TMJ performance, with broader implications about the costs and benefits of phenotypic plasticity as well as implications for how such biological processes affect connective tissue mechanobiology and pathobiology

    This study was performed to find the relationship between pain and joint effusion using magnetic resonance imaging (MRI) in temporomandibular disorder (TMD) patients. 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 chi2 test with SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). Spontaneous pain, provoked pain, and both spontaneous and provoked pain were significantly related to joint effusion in TMD patients (p 0.05). 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.

    Pure trigeminal motor neuropathy (PTMN) is a rarely described condition. We report the case of a 41-year-old woman infected with the human immunodeficiency virus (HIV1) and hepatitis C virus who presented with weakness of left temporalis and masseter muscles and painful left temporomandibular joint dysfunction (TMD) a few months after cerebral toxoplasmosis revealing acquired immunodeficiency syndrome (AIDS). Magnetic resonance imaging revealed severe wasting and fat replacement of the left temporalis, pterygoid and masseter muscles and showed neither abnormalities in the left motor nucleus of the trigeminal nerve nor compression of the left trigeminal nerve. Electromyographic examination gave evidence of denervation in the left temporalis, masseter and pterygoid muscles and blink reflex studies were normal, confirming the diagnosis of PTMN which was probably secondary to HIV and HCV co-infection.

    2014-05-01

    Headache and temporomandibular disorders should be treated together but separately. If there is marked limitation of opening, imaging of the joint may be necessary. The treatment should then include education regarding limiting jaw function, appliance therapy, instruction in jaw posture, and stretching exercises, as well as medications to reduce inflammation and relax the muscles. The use of physical therapies, such as spray and stretch and trigger point injections, is helpful if there is myofascial pain. Tricyclic antidepressants and the new-generation antiepileptic drugs are effective in muscle pain conditions. Arthrocentesis and/or arthroscopy may help to restore range of motion.

    2009-01-01

    Full Text Available Because nonespecific symptoms and signs are associated with others well-established in the temporomandibular disorders, it is difficult for the clinician to decide what symptoms and signs should be considered during the diagnosis and the treatment plan. Therefore, the aim of this literature review was to evaluate the prevalence of aural symptoms (otalgias, tinnitus, dizziness and deafness in patients with orofacial pain. Although several hypotheses have been proposed to explain the association between aural symptoms and temporomandibular disorders, the results of the previous studies differed in magnitude. For this reason, it is difficult to establish the prevalence of these aural symptoms concomitantly with temporomandibular disorders. Moreover, such relationship does not necessarily imply a cause-effect relationship. Because of the diagnosis complexity, different treatments must be considered, so the nonespecific symptoms of temporomandibular disorders can be effectively controlled as well. It is crucial for the the clinician to be aware of the possible etiology of aural symptoms, so he should determine if such symptoms may be associated with temporomandibular disorders and thus include them in the treatment.

    Full Text Available Objective: The purpose of this prospective study was to evaluate the incidence and degree of facial nerve damage and time taken for its recovery following surgery for temporomandibular joint (TMJ ankylosis. Materials and Methods: A total of 30 subjects with the TMJ ankylosis with or without history of previous surgery were included in this prospective study. House-Brackmann grading system was used to assess the function of the facial nerve post-operatively. Results: Most of the subjects were in the age range of 13-15 years. Eight subjects had bilateral ankylosis and remaining 22 had unilateral ankylosis. Out of 32 joints in which gap arthroplasty was performed, 4 had Grade 1 injury, 14 had Grade 2 injury, 12 had Grade 3, and 2 with the Grade 4 injury 24 h post-operatively. Whereas, out of 6 cases of interpositional arthroplasty 4 had Grade 1 injury and 2 had Grade 4 injury. According to House-Brackmann grading system, at 24 h, 78.9% patients had different grades of facial nerve injury, which gradually improved and came to normal limits within 1-3 months post-operatively. Comparison of change in the Grade of injury at 3 months follow-up as compared to baseline (24 h showed full recovery in all the cases (100% showing a statistically significant difference from baseline (P < 0.001. Conclusion: When proper care is taken during surgery for TMJ ankylosis, permanent facial nerve injury is rare. However, the incidence and degree of temporary nerve injury could be either due to the heavy retraction causing compression and or stretching of nerve fiber resulting in neuropraxia.

    A study was performed on the articular disk and periarticular tissues of the temporo-mandibular joint (TMJ) with immunohistochemical techniques to give evidence to the presence of neuroreceptors (NRec) in these sites. The study was carried out on tissue samples obtained from 10 subjects without TMJ disease and from 7 patients with severe TMJ arthritis and arthrosis. We use antibodies directed against following antigens: Gliofibrillary Acidic Protein (GFAP), Leu-7, Myelin Basic Protein (MBP), Neurofilaments 68 kD (NF), Neuron Specific Enolase (NSE), S-100 protein (S-100) and Synaptophysin (SYN). This study revealed that Ruffini's-like, Pacini's-like and Golgi's-like receptors can be demonstrated in TMJ periarticular tissues and that free nervous endings are present in the subsynovial tissues but not within the articular disk. We observed elongated cytoplamic processes of chondrocytes that demonstrated strong S-100 immunoreactivity but they were unreactive with all other antibodies. These cytoplamic processes were more abundant and thicker in the samples obtained from patients with disease TMJ. The results of this study confirm that different Nrec are detectable in TMJ periarticular tissues but they are absent within the articular disk. In the latter site, only condrocytic processes are evident, especially in diseased TMJ, and they might have been confused with nervous endings in previous morphological studies. Nevertheless the absence of immunoreactivity for NF, NSE and SYN proves that they are not of neural origin.

    The purpose of this study was to examine the differences in expert ratings of quality of magnetic resonance images (MRI) of the temporomandibular joint in 24 patients with suspected anterior disc displacement examined in randomized order at 1.5 and 3.0 T. Parasagittal (closed and opened mouth) and paracoronal sections were performed with a surface coil. Two experienced examiners blinded to patient status and type of MRI diagnosed the images according to position of condyle, position and changes in the signal, and disc shape. In addition, perceptibility of position and disc shape were assessed. A highly significant difference in the perceptibility of disc shape (P < 0.001) and position (P < 0.001) was obtained. With comparable examination sequences and identical resolution, the 3.0 T MRI of the temporomandibular joint increases the perceptibility of joint structures. (orig.)

    Bony fusion between the mandibular condyle and skull base involves temporomandibular joint (TMJ) bony ankylosis. This condition might originate from trauma, infection, or systemic disease. TMJ adhesion can develop after synovial damage. Both TMJ ankylosis and adhesion lead to functional impairment and pain. Here, we present a case of a 50-year-old female who had bony ankylosis of the right TMJ and adhesion of the left TMJ. She had otitis media in the right ear. A large mass in the right TMJ was observed on computed tomograph. Magnetic resonance image showed a large fused bone mass with normal bone marrow in the right TMJ and flattening of the condyle with a thin disk in the left TMJ. Gap arthroplasty with temporal fascia was performed on the right TMJ, and discectomy, high condylectomy, and coronoidectomy were performed on the left TMJ. During a 2-year follow-up after surgery, the patient had no recurrence

    To implement high-resolution morphologic and quantitative magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) using ultrashort time-to-echo (UTE) techniques in cadavers and volunteers. This study was approved by the institutional review board. TMJs of cadavers and volunteers were imaged on a 3-T MR system. High-resolution morphologic and quantitative sequences using conventional and UTE techniques were performed in cadaveric TMJs. Morphologic and UTE quantitative sequences were performed in asymptomatic and symptomatic volunteers. Morphologic evaluation demonstrated the TMJ structures in open- and closed-mouth position. UTE techniques facilitated the visualization of the disc and fibrocartilage. Quantitative UTE MRI was successfully performed ex vivo and in vivo, reflecting the degree of degeneration. There was a difference in the mean UTE T2* values between asymptomatic and symptomatic volunteers. MRI evaluation of the TMJ using UTE techniques allows characterization of the internal structure and quantification of the MR properties of the disc. Quantitative UTE MRI can be performed in vivo with short scan times. (orig.)

  8. On the analysis of condylar path versus real motion of the temporomandibular joint: application for Sicat Function.

    2015-01-01

    Analysis of temporomandibular joint (TMJ) function using condylar path tracings is a challenge in functionally oriented dentistry. In most cases, reference points on the skin surface over the TMJ region are defined as "arbitrary", "individual" or "kinematic" condylar hinge axis points, which are displayed as "condylar paths" in motion. To what extent these reference points represent the actual condylar paths in each individual patient is ultimately unclear because the geometric relationship of the actual condyle to the selected reference point is usually unknown. Depending on the location of the point on the condyle and the centers of rotation of mandibular movement, these trajectories can vary greatly during combined rotational and sliding movements (eg, opening and closing movements of the mandible); this represents a grid of points located in the vicinity of the TMJ. To record the actual condylar path as the movement trajectory of a given point (eg, the condylar center), technological solutions are needed with which to link the tracing technology with the appropriate imaging technology capable of scanning the condyle, including the points of interest, and displaying them in real dynamic motion. Sicat Function (Sicat, D-Bonn) is such a solution. Sicat Function links cone beam computed tomography (CBCT) scans (made using the Galileos CBCT scanner; Sirona, Bensheim, Germany) with ultrasound-based, three-dimensional (3D) functional jaw movement recordings of the mandible (made using the JMT+ Jaw Motion Tracker; Sicat, Bonn, Germany). Digital images of the dental arches acquired with the intraoral scanner Cerec system (Sirona) can also be superimposed. This results in the generation of a 3D model of the bony mandible, including the TMJ, which reproduces the 3D real dynamic movement of the condyles simultaneously with that of the condylar paths at defined points (with the condylar centers being a particular point of interest). Sicat Function is an integrated, digital

    Knowledge of normal appearances of the temporomandibular joint (TMJ) is paramount when assessing the joint for disease in juvenile idiopathic arthritis. Reliable features defining normal TMJs in children are limited. To establish reliable normal standards for the TMJ at magnetic resonance imaging (MRI). We included children and young adults aged 2-18 years undergoing a head MRI for reasons not believed to affect the TMJs. We assessed TMJ anatomy and contrast enhancement using a high-resolution 3-D T1-weighted sequence. We noted joint fluid and bone marrow oedema based on a T2-weighted sequence. Three experienced radiologists read all examinations twice in consensus and defined intraobserver consensus agreement. We evaluated the TMJs in 101 children and young adults (45 female), mean age 10.7 years (range 2-18 years). The intraobserver consensus agreement for the assessment of anterior condylar inclination in the sagittal/oblique plane was moderate to good (Cohen κ=0.7 for the right side). Cohen κ for intraobserver consensus agreement for condylar shape in the coronal plane on a 0-2 scale was 0.4 for the right and 0.6 for the left. Intraobserver agreement for measurement of joint space height and assessment of bone marrow oedema was poor. There was a statistically significant increase in anterior inclination by age in the sagittal plane on a 0-2 scale (P<0.0001). Eighty percent of the condyles showed a rounded shape in the coronal plane while 20% showed mild flattening. Thirty-five of 36 right TMJs showed contrast enhancement (mild enhancement in 32 joints, moderate in 3 joints). Subjective assessment of the anterior condylar inclination in the sagittal/oblique plane and condylar flattening in the coronal plane can be considered precise features for describing TMJ anatomy in healthy children. There is an increasing anterior inclination by age. Mild contrast enhancement of the TMJs should be considered a normal finding. (orig.)

    Although the etiopathophysiology of internal temporomandibular joint internal disorders (TMJ ID) is still unknown, it has been suggested that head and body posture could be related to its initial onset, development and perpetuation. The purpose of the present study was to observe the relationship between cervical spine X-ray abnormalities and TMJ ID. This investigation evaluated 30 subjects with internal TMJ disorder symptoms (test group) and 20 healthy subjects (control group). Subjects were submitted to clinical and radiographic evaluation. Clinical evaluation comprised anamnesis and stomatognathic system physical examination. Radiographic evaluation comprised analysis of lateral cervical spine X-rays by three physical therapists and tracing on the same images. The test group presented twice as much cervical spine hyperlordosis as the control group (20.7% versus 10.5%), but almost half of rectification prevalence (41.4 versus 79.0%, p = 0.03). After that, the test group was divided into three subgroups according to TMJ dysfunction severity, evaluated by Helkimo's index. These subgroups were not significantly different, but the subgroup with more severe TMD showed a tendency to cervical spine hyperlordosis prevalence. Results showed a tendency for subjects with more severe TMD to exhibit cervical spine hyperlordosis. Nevertheless, studies with a larger number of subjects suffering from severe TMD are encouraged in order to corroborate the present findings.

    The aim of this study was to investigate dentist's approaches to the use of splint therapy for myofascial pain, bruxism, and temporomandibular joint (TMJ) disorders and to assessment of treatment modalities. A 12-item questionnaire was developed to determine dentists' knowledge of TMJ disorders and approaches for occlusal splint treatments. The researchers spoke with each dentist included in the study at his/her clinic or by telephone to assess their immediate knowledge and approach to the TMJ disorders. Chi-squared test was performed to analyze the values. The confidence interval was set as 95%. A total of 370 dentists working in Turkey were participated in this study. The most common splint application reason for occlusal splint treatment was bruxism (77.8%) while TMJ pain was very rare (%1.4). The use of hard splint ratios for 0-5 years of professional experience was 57.0%, 42.4.0%, and 26.8% for the experience of 5-15 years and over 15 years groups, respectively (P < 0.001). While the dentists' with sufficient knowledge soft splint application rates were 11.6%, hard splint application rates were 43.4% for the dentists with sufficient knowledge. Occlusion adjustment rate of dentists who practice in all three groups was under 16.0%. The knowledge of the dentists about TMJ disorders and occlusal splint therapy were found to be insufficient. Their knowledge decreased with increasing experience.

    The morphology of the temporal part of the human temporomandibular joint (TMJ) changes drastically during postnatal development. The glenoid fossa will acquire its characteristic S shape and a tubercle will develop. The combined results of the literature and of this study allow a reconstruction of the actual growth processes. The roof of the glenoid fossa appears to enlarge forward by remodeling while sagittal and vertical growth is mainly achieved by deposition at the top of the tubercle. These latter changes result in a steeper slope of the eminence and take place in 3 phases, parallelling the eruption of the first incisors, the permanent first molars and the permanent second molars. While the zygomatic arch thickens by deposition at all surfaces, it also remodels downward relative to the external meatus. As a result, the neonate anulus occupies a lower position relative to this arch than does the adult meatus.

    A randomized clinical trial involving adult patients with bilateral temporomandibular joint (TMJ) hypermobility referred for treatment was implemented. The sample comprised 30 consecutive patients, who were divided randomly into two groups. The TMJ hypermobility was treated with either saline (placebo group) or dextrose injections (study group). The solution was injected into five different TMJ areas in three sessions at monthly intervals. The predictor variable was the treatment technique. The outcome variables were visual analogue scale (VAS) evaluations and maximum inter-incisal opening (MIO). Outcome variables were recorded preoperatively and at 12 months postoperatively. Descriptive and bivariate statistics were computed, and significance was set at a P-value of dextrose prolotherapy is no more effective than placebo treatment for any of the outcome variables of TMJ hypermobility assessed.

    Published descriptions of nonseptic arthritis of the equine temporomandibular joint (TMJ) are rare and large studies investigating variations in the TMJ for asymptomatic horses are lacking. The objectives of this cross-sectional, retrospective, multi-institutional study were to describe anatomical variations in the TMJ detected using computed tomography (CT) in an equid population asymptomatic for TMJ disease and determine whether these variations were associated with patient signalment, reason for CT examination, or CT slice width. Medical records at eight hospitals were searched for horses that had head/neck CT scans and no clinical signs of TMJ disease. Age, breed, sex, clinical presentation, and CT slice width data were recorded. Alterations in CT contour and density of the mandibular condyles, mandibular fossae, and TMJ intra-articular discs were described for each horse. Generalized logistic regression was used to test associations between anatomical variations and horse age. A total of 1018 horses were sampled. Anatomical variations were found in TMJ CT images for 40% of horses and 29% of joints. These were dichotomous with regard to age. Horses horses commonly had spherical hypodensities within the mandibular condyles consistent with bone cysts; and hyperdense regions of the intra-articular disc consistent with dystrophic mineralization. Findings indicated that TMJ anatomic variations were common in CT images of younger and older horses asymptomatic for TMJ disease. Future studies are needed to more definitively characterize these CT variations using gross pathology and histopathology. © 2016 American College of Veterinary Radiology.

    A penetrating injury by a foreign body is comparatively common in the oral and maxillofacial region. On the other hand, injury to the temporomandibular joint (TMJ) by a foreign object is very rare. The TMJ is an anatomically narrow space surrounded by hard bony processes. An unusual case of trauma with severe trismus caused by a foreign body that impaled the TMJ is reported. A 55-year-old man presented with a 5 × 1-cm laceration to the right cheek caused by a flying object propelled during the use of a lawn mower. The edge of the foreign body had a metallic wire, which became imbedded in the wound. His jaw opening was severely limited. Computed tomography revealed that the foreign body was 3 mm in diameter and was impaled on the articular capsule. The object was successfully removed, and the wound and interior of the TMJ were irrigated. Rehabilitation of mouth opening was started on postoperative day 3. On day 9, mouth opening had improved to 35 mm, and he was discharged. After 1 year, mouth opening was 45 mm with no sign of any TMJ disorders. © 2016 John Wiley & Sons A/S.

    The purpose of this study was to characterize the tensile stress-strain behavior of the porcine temporomandibular joint (TMJ) disk with respect to collagen orientation and strain rate dependency. The apparent elastic modulus, ultimate tensile strength, and strain at maximum stress were measured at three elongation rates (0.5, 50, and 500 mm/min) for dumbbell-shaped samples oriented along either anteroposterior or mediolateral axes of the disks. In order to study the effects of impact-induced fissuring on the mechanical behavior, the same properties were measured along each orientation at an elongation rate of 500 mm/min for disks subjected to impulsive loads of 0.5 N. s. The results suggested a strongly orthotropic nature to the healthy pristine disk. The values for the apparent modulus and ultimate strength were 10-fold higher along the anteroposterior axis (p disks for either orientation (p > 0.05). The results demonstrated the importance of choosing an orthotropic model for the TMJ disk to conduct finite element modeling, to develop failure criteria, and to construct tissue-engineered replacements. Impact-induced fissuring requires further study to determine if the TMJ disk is orthotropic with respect to fatigue.
