Lateral and superior-lateral dislocations of the intact condyle are a rare complication, following traumatic insult to the mandible. We report an unusual case of a 54-year-old male patient who experienced both types of dislocations of the intact condyles with symphysis fracture following a road-traffic accident. Under general anesthesia, conventional manipulation was unsuccessful in relocating the condyles into the glenoid fossa. After applying a percutaneous traction force, using a bone traction hook placed at the sigmoid notch, the displaced intact mandibular condyles were repositioned, and the symphyseal fracture was finally reduced and fixed. The mouth opening was within normal limits, and favorable occlusion was confirmed one month postoperatively. To our knowledge, this is the first case of dislocation of both intact condyles--associated with symphysis fracture--being reduced with bone traction hook.
Sclerosing polycystic adenosis (SPA) is an uncommon salivary gland lesion similar to fibrocystic disease and adenosis of the mammary glands. To our knowledge, 51 cases of SPA have been reported in the literature to date. Sclerosing polycystic adenosis is well circumscribed, yet not encapsulated, and has sclerotic and irregularly defined lobules composed of abundant hyalinized collagen with ductal, acinar hyperplasia and areas of apocrine metaplasia. Focal cystic spaces within a dense fibrotic stroma are also characteristic features of this lesion. Most of the known cases occurred mainly in the parotid gland. In this article, we describe a case of SPA occurring in the parotid gland of a 47-year-old male patient.
Tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis, continues to be a major health problem worldwide. Primary TB infection is mostly pulmonary, but it may also occur in the lymph nodes, abdomen, skin, meninges, joints, and central nervous system. TB in the head and neck region usually occurs in the cervical lymph nodes, but is extremely rare in the temporomandibular joint (TMJ). This rarity increases the risk for not considering TB in the differential diagnosis of patients presenting with TMJ pain. This article describes an unusual case of a 53-year-old man with painful swelling in the right preauricular area accompanied by difficulty in mouth opening. After surgical exploration, histopathologic findings revealed TB in the TMJ. The findings of this case highlight the importance of considering TB in the differential diagnosis of TMJ pain, especially for patients from endemic areas, patients who have lived or visited those areas, or patients with a preauricular swelling in the TMJ area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
