Article Synopsis
- The study investigates the effects of removing one submandibular gland on the size of the opposite gland in patients who had oral cancer surgeries between 2008 and 2023.
- Using 3D imaging, researchers found that the volume of the remaining gland increased significantly after the excision, suggesting a compensatory adaptation.
- The findings highlight the importance of considering this volume change in post-operative care and surgical planning to improve treatment outcomes for oral cancer patients.
Purpose: This study aimed to evaluate age-stratified radiographic features in temporomandibular joint osteoarthritis using cone-beam computed tomography.
Materials And Methods: In total, 210 joints from 183 patients (144 females, 39 males, ranging from 12 to 88 years old with a mean age of 44.75±19.
Calcium pyrophosphate dihydrate deposition disease in the temporomandibular joint: diagnosis and treatment.
Maxillofac Plast Reconstr Surg
December 2018
Background: Calcium pyrophosphate dihydrate deposition disease (CPDD) is a rare disease in the temporomandibular joint (TMJ) space. It forms a calcified crystal mass and induces a limitation of joint movement.
Case Presentation: The calcified mass in our case was occupied in the left TMJ area and extended to the infratemporal and middle cranial fossa.
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.

Materials And Methods: CT images of skeletal Class III children (7 boys, 9 girls, mean age: 11.4 years) were taken parallel to the Frankfurt horizontal plane.
Purpose: The purpose of this study was to evaluate a new technique for localizing impacted mesiodens using its horizontal magnification ratio on panoramic radiographs.
Materials And Methods: Location-magnification equation of a panoramic equipment was obtained from horizontal magnification ratio of a metal ball which was located variable positions from the center of image layer at interval of 2 mm. Panoramic radiographs were obtained from a skull phantom with a metal ball which was a substitute for impacted mesiodens and was embedded 10mm(Group 1), 15mm(Group 2), and 20mm(Group 3) posterior to the central incisor.
