Complications of alloplastic temporomandibular joint (TMJ) prostheses can lead to stress and anxiety for the patient and the surgical team, and prosthesis substitution is sometimes required. The aim of this case report is to describe the surgical finding of synovial entrapment with interposed fibrosis in a postoperative alloplastic TMJ revision, managed effectively with adequate surgical debridement. The authors believe that synovial entrapment needs to be considered as a possible postoperative complication of total joint replacement when no clear symptoms of infection, metal hypersensitivity, osteolysis, or heterotopic bone formation are present.

The present review summarized the current advances and novel research on minimal invasive techniques for musculoskeletal disorders. Different invasive approaches were proposed in the physical therapy field for the management of musculoskeletal disorders, such as ultrasound-guided percutaneous needle electrolysis, dry needling, acupuncture and other invasive therapy techniques, discussing about their worldwide status, safety and interventional ultrasound imaging. Indeed, dry needling may be one of the most useful and studies invasive physical therapy applications in musculoskeletal disorders of different body regions, such as back, upper limb, shoulder, arm, hand, pelvis, lower limb, neck, head, or temporomandibular joint, and multiple soreness location disorders, such as fibromyalgia.

Temporomandibular joint (TMJ) reconstruction with alloplastic prosthesis is a commonly performed procedure, which can be used as a treatment for improving pathologic conditions affecting the TMJ. Depending of the severity of the condition, the patient's ability to eat can be impaired, which in turn can affect their quality of life. Several syndromes can affect the patient's facial features, and some of those also affect TMJ's. Read More

Context: Internal derangements of temporomandibular joint (TMJ) with associated symptoms which do not respond to conservative therapies are refractory cases of temporomandibular joint dysfunction syndrome (TMD). Minimally invasive techniques like arthrocentesis and platelet rich plasma (PRP) injections are usually employed to improve TMJ symptoms and function in these cases.

Aims: To compare PRP with arthrocentesis for evaluating the effectiveness of PRP in relieving symptoms of refractory TMJ pain dysfunction syndrome. Read More

Background: Based on a variety of studies conducted in recent years, some of the factors that might contribute to the negative treatment responses of some TMD patients have been elucidated.

Methods: This paper describes known vulnerability factors that make individuals susceptible to developing temporomandibular disorders (TMDs), as well as those that contribute to the perpetuation of such problems. In addition, the topic of iatrogenesis is discussed as a major contributor to the negative outcomes that can be seen in this field. Read More

Goldenhar syndrome, or oculoauriculovertebral dysplasia, represents approximately 10% of craniofacial microsomia anomalies. These patients have a variety of clinical features that are relevant to anesthesia providers, including a high-arched palate, mandibular hypoplasia, micrognathia, and temporomandibular joint (TMJ) malformation. The oral manifestations of Goldenhar syndrome range from malocclusion to complex TMJ involvement. Read More

Chronic pain syndromes in the neck and shoulder girdle are one of the important clinical problems due to their high prevalence. In addition, it's of great interest to study the mutual influence of the musculoskeletal system pathology, balance organs and dentoalveolar system due to the possible negative impact of these structures on each other which surely affects the treatment timing and its results.

Objective: To develop a diagnostic algorithm and a comprehensive program for the treatment and rehabilitation of patients with cervicobrachialgia combined with pathological dental occlusion. Read More

The article describes case history and multiphase treatment of the patient with attacks of vertigo, initially regarded as the onset of Meniere's disease, but later qualified as secondary positional attacks with combined musculoskeletal pathology of the craniovertebral region and temporomandibular joint. Medicinal, local and surgical treatment led to the perfect result. Thus, the team work of neurologist, otolaryngologist, maxillofacial surgeon and orthodontist led to the successful elimination of vertigo attacks. Read More

Background: The term temporomandibular disorder (TMD) includes disorders of the temporomandibular joints (TMJ), masticatory muscles and adjacent tissues. Several studies have examined the effectiveness of manual therapy (MT) for TMDs by evaluating changes in pain and maximum mouth opening (MMO). Nevertheless, the effectiveness of MT exclusively applied to the craniomandibular structures (craniomandibular manual therapy (CMMT)) on pain and TMJ range of motion remains unclear. Read More

The clinical picture of coronavirus disease 2019 (COVID-19) in various target organs has been extensively studied and described. However, relatively little is known about the characteristics of oral cavity involvement. This is surprising, considering that oral mucosal and salivary gland cells are known targets for the direct replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and that the presence of the virus in saliva is a source of transmission of the infection.

Purpose: Maxillomandibular fusion (syngnathia) is a rare craniofacial anomaly. It occurs as either fibrous (synechiae) or bony (synostosis) fusion of jaw or fusion of mandible to zygoma, tuberosity, hard palate and temporal bone. There are several documentations delineating this condition but owing to its varying presentation, association with both intraoral and extraoral anomalies and syndromes, reviewing it has been as uphill task.
