We report the results of a longitudinal radiographic study of ossification of the stylohyoid ligament in a sample of patients treated for minor malocclusions. The results suggest that the vast majority of ossified sites in the stylohyoid ligaments are established during childhood and adolescence. The mean length of the sites shows a fairly rapid, linear increase with age until the end of adolescence; any further increase is nonlinear and occurs at a much slower rate. In young individuals the ossified sites were predominant in the superior part of the ligament. With increasing age ossified sites became prevalent also in other parts of the ligament. Ossified sites in the inferior part close to the hyoid bone were more common than previously reported.

TFE3 rearrangements characterize histogenetically, topographically, and biologically diverse neoplasms. Besides being a universal defining feature in alveolar soft part sarcoma (ASPS) and clear cell stromal tumor of the lung, TFE3 fusions have been reported in subsets of renal cell carcinoma, perivascular epithelioid cell tumor (PEComa), epithelioid hemangioendothelioma and ossifying fibromyxoid tumors. TFE3 -related neoplasms are rare in the head and neck and may pose diagnostic challenges.

Anterior cruciate ligament reconstruction (ACLR) is one of the more common procedures performed worldwide and perhaps the most widely studied construct in orthopedic literature. Interference screws are reliable and frequently used for ligament reconstruction, providing rigid fixation and facilitates graft incorporation allowing for the physiologic loads of early rehabilitation. The purpose of this study was to determine the bio-integration profile and quality of soft tissue graft when using mineral fiber-reinforced screws in an ACLR interference model.

A 2-year-and-10-month-old boy presented with multiple masses in the neck and chest for over 3 months. The child had a history of unstable walking, with hard lumps visible at the injury sites after falls, which would resolve on their own. Following a recent injury, a mass was discovered in the posterior neck, protruding above the skin surface and accompanied by limited joint movement.

Juvenile ossifying fibroma (JOF) and its variants, including juvenile psammomatoid ossifying fibroma (JPOF), represent rare yet clinically significant benign fibro-osseous lesions that primarily occur in children and young adolescents. They can be found in diverse anatomical sites such as the jaw, nasal cavity, paranasal sinuses, and orbit. JOF exhibits an aggressive nature, necessitating early radiological detection and surgical intervention.
