TMJ Metastasis: Evaluation of 3 Patients.

Metastases of the articular process, temporomandibular joint (TMJ), are rare findings. Their frequency is around 5% of patients with metastatic involvement of the mandible. The most common primary tumor is adenocarcinoma of the lung in women and adenocarcinoma of the prostate in men.

Micro-computed tomography evaluation of bone architecture in various forms of unilateral condylar hyperplasia.

Condylar hyperplasia is one of the causes of facial asymmetry and malocclusion, characterized by enlargement of the lower jaw due to excessive condyle growth activity. The aim of this study was to use micro-computed tomography (micro-CT) to evaluate the bone architecture of the condylar head and determine whether there are differences between patients with various forms of unilateral condylar hyperplasia (UCH): hemimandibular hyperplasia, elongation, and mixed form. The cohort consisted of 28 patients with a mean age of 21.

The Manifestations of Covid-19 Infection. Manifestations in Patients with Temporomandibular Joint Disorders.

The authors present a group of patients who were treated for exacerbation of temporomandibular joint disorders (TMD) following Covid-19 infection and who in the past had successfully undergone surgery of the temporomandibular joint (TMJ). The group consisted in total of 21 patients who relapsed after contracting Covid-19. There were 4 men and 17 women, the average age was 45.

Reconstruction of Temporomandibular Joint and Skull Base Defect Following Osteosarcoma Resection.

Osteosarcoma of the jaw is uncommon, occurring in about 6% to 8% of cases. The authors present the case report of a (woman 72-year-old) with osteosarcoma involving the temporomandibular joint (TMJ). Radical surgery was chosen with resection of the tumor together with the condyle, the coronoid process, the zygomatic arch and eroded bone of the skull base at the site of the joint cavity.

A Complex Evaluation of the In-Vivo Biocompatibility and Degradation of an Extruded ZnMgSr Absorbable Alloy Implanted into Rabbit Bones for 360 Days.

The increasing incidence of trauma in medicine brings with it new demands on the materials used for the surgical treatment of bone fractures. Titanium, its alloys, and steel are used worldwide in the treatment of skeletal injuries. These metallic materials, although inert, are often removed after the injured bone has healed.
