The article provides data on the anatomical features of temporomandibular joint in the second trimester of fetal development, certain methods of anatomy, morphometry and craniometry. The glenoid fossa in fetuses aged 4-6 months was found to be flat. The bone substance in the glenoid fossa is thin. One can see the development of the elements of the synovial membrane in the articular capsule. In the lower and upper parts of the articular cavity, the folds and ligaments of the connective tissue plate are identified, and the capillaries grow into the synovial membrane. In some places there are connective tissue membranes between the surfaces of the temporal bone and the articular disk, the articular disk and the head of mandible. Macroscopically, the articular disk has a dense structure, it is arranged between the articular surfaces, from the back surface of the articular disk to the inner surface of the articular capsule the taenia of the connective tissue is identified. Anteriorly, the articular disk is attached in the area of the future articular tubercle. The right and lefts temporomandibular joint are of the same size. In the dynamics of the second trimester of intrauterine development, the temporomandibular joint is characterized by the presence of a flat glenoid fossa and the absence of an articular tubercle. An increase in all craniometric indices is observed, indicating an increase in the total bone mass of the skull and an increase in the size of the temporomandibular joint.

Malignant (invasive) otitis externa (MOE) is an infection involving the external auditory meatus (EAM), most often found in elderly diabetics, which carries a high morbidity and mortality. In advanced cases it may give rise to osteomyelitis and cranial neuropathies. This is a case of MOE, which invaded the posterior wall of the right temporomandibular joint (TMJ), resulting in severe trismus and pain. Subsequently, this required treatment by replacement of the glenoid fossa with a Silastic® prosthesis.

Joint Treatment

Synovial chondromatosis is an uncommon disease of cartilaginous transformation of synovial membrane with formation of loose bodies within the joint space. A case involving the temporomandibular joint (TMJ) is presented. In the TMJ, this disorder occurs more often in females and is usually on the right side. Symptoms include preauricular swelling, pain, and tenderness. Radiographs of the TMJ may be normal, but frequently show multiple, partially calcified loose bodies within the joint. Treatment consists of removal of the loose bodies together with all affected synovium. If the meniscus is excised, reconstruction with a Silastic prosthesis is recommended.

Synovial chondromatosis is a condition in which loose fragments of cartilage develop in the synovial membrane of joints due to metaplasia of the subsynovial connective tissue. The resulting symptoms are similar to those of temporomandibular joint (TMJ) dysfunction. Clinical diagnosis can therefore be challenging. Synovial chondromatosis rarely occurs in the TMJ as its predilection is towards larger joints. A systematic review up until June 2010 reported a total 241 cases of TMJ synovial chondromatosis. We present two cases of TMJ synovial chondromatosis seen and treated in our department. CPD/Clinical Relevance: Awareness of TMJ synovial chondromatosis can enable patients to receive appropriate management before progression of the condition.

One of the most common causes of chronic pain in the facial region, including in the trigeminal nerve link, which is not associated with dental diseases, is pain dysfunction of the temporomandibular joint. At the same time, there is evidence in the literature that there are relationships between pain dysfunction of the temporomandibular joint, abnormal occlusion, cervical-muscular tonic phenomena, postural disorders, dysfunction of the Autonomous nervous system and cochleovestibular manifestations. At the same time, neurophysiological indicators of functional disorders in the maxillofacial region and intersystem interactions in pain dysfunction of the temporomandibular joint are insufficiently studied.Goal. The aim of the work is to evaluate the neurophysiological features of trigeminal afferentation in terms of trigeminal somatosensory evoked potentials (TSWP) and the auditory conducting system of the brain in terms of acoustic stem evoked potentials (ASVP) in distal occlusion of the dentition with pain dysfunction of the temporomandibular joint (TMJ) in comparison with physiological occlusion in students 18-21 years old. Material and methods. The main study included 41 students with distal occlusion (21 girls and 20 boys), (grade II Engl, symmetrically right and left in 14 people, and grade II Engl on the left and grade I on the right in 12 people, grade I on the left and grade II on the right in 15 people). All respondents with distal occlusion and who were practically healthy signed an informed consent to participate in the study. We used complex orthodontic methods of examination, subjective degree of severity and intensity of pain in the TMJ, assessment of the Autonomous nervous system (samples and tests), and neurophysiological methods for assessing TSVP and ASVP. Results. Significant differences in ASEP parameters were found in the group of respondents with distal occlusion in the form of a decrease in the latency period of peak I, III, and V compared to physiological occlusion, that correlated with the subjective assessment (in points) of cochleovestibular disorders. According to the TSVP study, a decrease in the duration of latent periods was found, which indicates an increased excitability of non-specific brain stem structures at the medullo-ponto-mesencephalic level compared to the control group. Conclusions. The results obtained are supposed to be used for differential diagnostics, including such dental diseases as TMJ pain dysfunction, occlusion abnormalities accompanied by pain syndrome. Additional functional diagnostics of multi-modal VP of the brain (acoustic evoked potentials, trigeminal evoked potentials) can be performed in conjunction with indicators of autonomic nervous system dysfunction, with parameters of severity of clinical symptoms of cochleovestibular disorders, musculoskeletal dysfunction the maxillofacial area, with indicators of pain, which will determine the tactics and effectiveness of subsequent treatment.

Abstract Background Otomastoiditis is a very frequent affection and a current complication of mal-treated benign ear infections in children. However, this a very rare case of the association of two rare complications of otomastoiditis in a newborn. On the one hand, septic arthritis of the temporomandibular joint which is a very rare condition that is difficult to diagnose, and when unrecognized or not treated accordingly, it can resolve in serious infectious complication and or definitive injury to the temporomandibular joint. On the other hand, osteomyelitis of the clavicle is also very rare, and only a few cases have been cited in the literature concerning infants. Case presentation This 46-day-old infant was brought to pediatric emergency consultation for 2 swelling inflammatory bulges, one in the right mastoid and pre-auricular regions, and another in the right basi-cervical area. The infant was hypertrophic febrile, hypotonic, and pale. He had preserved archaic reflexes. Besides, blood test showed an inflammatory syndrome, inflammatory anemia, and no other abnormalities. Upon supplementary computed tomodensitometry exam, the diagnosis of a combination of septic arthritis of the right temporomandibular joint and sub-periosteal abscess of the ipsilateral clavicle in a context of hypotrophy and malnutrition was suspected. A pus sample was obtained for bacteriological evaluation, after which the infant had a course of intravenous associated antibiotics, along with nutritional assessment and management. Surgical drainage of both collections was performed. The 6-month follow-up was satisfactory, without clinical signs of functional impact on temporomandibular joint, or acromioclavicular joint. Conclusion This work stresses the necessity of thorough clinical examination of infants even in cases of benign ear infections, as well as the importance of adapted treatment and follow-up, which could allow early diagnosis, appropriate treatment, or even prevention of severe complications that can be associated with such benign conditions.

(1) Background—The aim of the present study was to evaluate the correlation between the temporomandibular joint (TMJ) osseous morphology of normal skeletal pattern individuals with different dental malocclusions by using cone-beam computed tomography (CBCT). (2) Methods—The CBCT images of bilateral TMJs in 67 subjects with skeletal class I and average mandibular angle (26 males and 41 females, age range 20–49 years) were evaluated in this study. The subjects were divided into class I, class II division 1, and class II division 2 according to the molar relationship and retroclination of the maxillary incisors. Angular and linear measurements of TMJ were evaluated and the differences between the groups were statistically analyzed. (3) Results—Intragroup comparisons showed statistical differences for articular eminence inclination, the width of the glenoid fossa, the ratio of the width of the glenoid fossa to the depth of the glenoid fossa, the condylar angle, and the intercondylar angle between the malocclusion groups. The measurements of the glenoid fossa shape showed no significant difference between the left and right sides. Females showed more differences in the morphological parameters of TMJ between the three malocclusion groups than the males. (4) Conclusion—The present study revealed differences in the TMJ osseous morphology between dental class I and class II malocclusions in the normal skeletal pattern.

Abstract Objectives The purpose of this study was to evaluate the short-term effect of active skeletonized sutural distractor (ASSD) appliance on temporomandibular joint morphology of class III malocclusion subjects. Materials and Methods This was a prospective interventional study. Cone-beam computerized tomography (CBCT) images of 22 patients were taken before and after treatment by using Planmeca Promax 3D CBCT machine version 2.9.2 (Planmeca OY Helsinki, Finland). The condylar width, height, length, roof of glenoid fossa thickness, and all joint spaces were measured. The condylar position was determined based on Pullinger and Hollander formula. The condylar shape was determined as per Kinzinger et al. The condylar volume was calculated by using Mimics software (Materialize, Belgium). Statistical Analysis Data analysis was performed by using SPSS software version 24. Wilcoxon paired signed-rank test was used to compare the difference in temporomandibular joint morphology and condylar volume between pre- and post-treatment measurements. Chi-square test was used to compare the condylar position and shape. Results The superior (p = 0.000 on the right side, p = 0.005 on the left side) and posterior joint spaces (p = 0.000 on both sides) were decreased after the treatment, respectively. The condyles were rotated upward and backward, thereby increasing the anterior joint spaces (p = 0.000 on both sides) after the treatment. The condylar volume increases after treatment, but no significant differences were observed (p = 0.903 on the right side, p = 0.062 on the left side). Conclusion The significant changes were observed in joint spaces. The condyles were more anteriorly placed before treatment. Condylar position and shape alter in response to ASSD treatment. The condylar volume did not show any significant change.

Background. HFM patients’ reconstruction has always been a challenge for maxillofacial surgeons, and numerous reconstructive techniques have been described. Surgical treatment depends on the patient’s age and contemplates Temporomandibular Joint (TMJ) reconstruction in conjunction with orthognathic surgery, usually necessary following completion of growth to maximize the functional and esthetic results. Distraction osteogenesis had gained popularity as valid alternative in growing patients, but the two primary methods to reconstruct the TMJs involve the use of autogenous, using free or microvascular bone grafts, or alloplastic graft, but there is no widely accepted method. Methods. The increasing use of temporomandibular prosthesis for temporomandibular problems has led us to use them even in HFM. A case of female nongrowing patients with HFM type IIb treated with temporomandibular prosthesis in an all-in-one protocol is presented. Results. Incisal opening, measured with BioPAK system (Bioresearch Inc., Milwaukee, USA), was 21.4 mm in the presurgical period and 32.2 mm after all-in-one procedure, for an increase of 50.5%. Excursive movement to the right side was 2.2 mm in the presurgical period and was 1.5 mm after surgery, for a decrease of 31.8%. Left excursion movement changed from 5 mm to 6.1 mm, for an increase of 22.0%. Conclusions. The TMJ Concepts patient-fitted TJP in conjunction with orthognathic surgery for TMJ and jaw reconstruction is a valid option for patients with HFM.

Prolonged submergence imposes special demands on the cardiovascular system. Unlike the situation in diving birds and mammals, crocodilians have the ability to shunt blood away from the lungs, despite having an anatomically divided ventricle. This remarkable cardiovascular flexibility is due in part to three anatomical peculiarities: (1) an 'extra' aorta (the left aorta) that leaves the right ventricle and allows the blood from the right ventricle to take an alternative route into the systemic circulation instead of going to the lungs; (2) the foramen of Panizza, an aperture that connects the right and left aortas at their base immediately outside the ventricle; and (3) a set of connective tissue outpushings in the pulmonary outflow tract in the right ventricle. Using high-resolution angioscopy, we have studied these structures in the beating crocodile heart and correlated their movements with in vivo pressure and flow recordings. The connective tissue outpushings in the pulmonary outflow tract represent an active mechanism used to restrict blood flow into the lungs, thus creating one of the conditions required for a right-to-left shunt. We observed that the foramen of Panizza was obstructed by the medial cusp of the right aortic valve during most of systole, effectively differentiating the left and right aortic blood pressure. During diastole, however, the foramen remained open, allowing pressure equilibration between the two aortas. Contrary to current theories, we found that the left aortic valves were unable to cover the foramen of Panizza during any part of the cardiac cycle, supporting the reversed foramen flow hypothesis. This would ensure a supply of blood to the coronary and cephalic circulation during a complete shut-down of the left side of the heart, such as might occur during prolonged submergence.
