1/7. Mandibular and temporomandibular joint arthropathy in the differential diagnosis of the parotid mass.

    OBJECTIVE: To increase awareness of temporomandibular joint and mandibular disease in the overall evaluation and diagnosis of the parotid mass. STUDY DESIGN: We describe clinical presentations of pigmented villonodular synovitis and synovial chondrocalcinosis of the temporomandibular joint, as well as osteoma of the mandible, as they may initially suggest primary neoplasms of the parotid gland. CONCLUSIONS: Preauricular swelling is a common presenting symptom for patients visiting an otolaryngologist. Often this symptom is suggestive of a parotid mass. However, lesions of the temporomandibular joint and mandible may also present in this fashion.

2/7. Misdiagnosed iuxta-articular osteoid osteoma of the calcaneus following an injury.

    The diagnosis of osteoid osteoma, in usual localizations, is generally simple. In iuxta-articular localizations this tumor may be unrecognized and the diagnosis delayed. Injury has been sometimes correlated with the onset of symptoms and this can make the diagnosis even more difficult. We present a case of osteoid osteoma of the calcaneus iuxta-articular to the subtalar joint in a 17-year-old basketball player. He had a history of initial injury, ankle sprain during training, followed by pain and swelling. He was initially treated for lateral ligament lesion of the ankle with unsatisfactory results. After acute trauma the pain changed becoming chronic and mostly nocturnal disappearing when rofecoxib was taken. Standard x-ray didn't show the lesion. Nuclear Magnetic Resonance (NMR) and scintigraphic results were not well interpreted but these clinical changes and Computed tomography (CT) images supported the diagnosis of osteoid osteoma. The complete resection of the bone lesion resolved all the symptoms and the histological report confirmed the suspected diagnosis.

3/7. The vascularized fibular flap for mandibular reconstruction.

    Vascularized fibular bone grafts have advantages over other bone grafts in the restoration of the contour and function of defective mandibles. The fibular graft can be tailored to fit even major mandibular defects; in combination with preformed temporomandibular joint prostheses total mandibular reconstruction can be performed in a single procedure. The fibular transplant is considered ideal for the insertion of implants to support dental suprastructures to obtain maximal oral rehabilitation. We have used fibular grafts in eight cases for primary or secondary reconstruction of a variety of mandibular defects resulting from cancer, chronic osteomyelitis or gunshot injuries. The results have been most encouraging with respect to function and cosmetic appearance. There have been no transplant failures and minimal donor site complications.

4/7. Osteolipoma arising adjacent to the sternoclavicular joint. A case report.

    A 45-year-old woman presented with one-year history of a mass on her chest. Computed tomography and magnetic resonance imaging demonstrated a tumour near the sternoclavicular joint. The tumour was diagnosed as osteolipoma histologically after resection. Osteolipoma is a rare tumour and this may be the first report of osteolipoma arising adjacent to the sternoclavicular joint.

5/7. Computed tomography in differential diagnosis of temporomandibular joint disorders.

    Computed tomography (CT) has great potential for imaging intra- and extracapsular hard-tissue abnormality of the temporomandibular joint (TMJ). CT is not the best method of imaging disk position and form. For differential diagnosis of TMJ disorders, CT is especially successful in bony lesions. The study includes 16 examples of TMJ hard-tissue abnormality. In the differential diagnosis of all cases, CT played a decisive role.

6/7. Post traumatic osteoma of tibial insertion of medial collateral ligament of knee joint.

    Two cases are presented of post traumatic para-articular osteoma developing at the site of tibial attachment of the medial collateral ligament of knee joint. These occurred after injuries sustained while playing football and in one case the ossified mass was treated with surgical excision for unresolved symptoms after conservative measures. A comparison is made with Pellegrini Stieda disease, which is a similar affection of the femoral insertion of the medial ligament of the knee joint.

7/7. Prosthodontic and surgical management of a patient with an osteoma of the temporomandibular joint.

    Osteomas of the temporomandibular joint are rare. This article presents a case report delineating treatment of a partially edentulous patient using a team approach for an osteoma originating from the anterolateral aspect of the glenoid. The tumor was diagnosed with the aid of a panoramic radiograph and a computerized axial tomograph. Interim prostheses with anterior teeth and posterior teeth with nonanatomic occlusal surfaces were fabricated before surgery. After surgical excision of the osteoma, the interim prostheses were periodically adjusted as the mandibular condyle gradually shifted into the space that was previously occupied by the tumor. Final removable prostheses were fabricated after the condyle had stopped shifting.
