Introduction: Rare FGF23-producing mesenchymal tumors lead to paraneoplastic tumor-induced osteomalacia (TIO) presenting with phosphate wasting, hypophosphatemia, chronic hypomineralization of the bone, fragility fractures and muscle weakness. Diagnosis of TIO requires exclusion of other etiologies and careful search for a mesenchymal tumor that often is very small and can appear anywhere in the body. Surgical removal of the tumor is the only definitive treatment of TIO. Read More

There is no accepted method of reporting mandibular fracture that reflects incidence, treatment and outcome for individual cases. As most series include anatomical site only for all fractures, the aim was to establish a new method to report fractures based on a systematic review of the literature and an internal audit. The classification proposed is: Class I; condyle, II; angle, IIc; II+condyle, III; body/symphysis, IIIc; III+condyle, IV; multiple fractures not including condyle, IVc; IV+condyle, V; bilateral condyle±other fracture(s).

Purpose: Decision making in the management of condylar head fractures remains difficult due to its dependency on multiple factors like fracture type, degree of dislocation, patient`s age and dental condition. As open reduction and internal fixation (ORIF) of condylar head fractures (CHFs) becomes more popular, the question of osteosynthesis removal is controversial. So far, information on volumetric changes after ORIF are available for a short-term period (<6 months) only. Read More

Background: Fractures of the mandible are common in elderly patients, and among them, condylar fractures are the most frequent type. A change in occlusion is the most common physical finding in patients with fractures of the mandible. Therefore, it is challenging to identify mandibular fractures in posterior edentulous patients due to the lack of posterior occlusal contacts. Read More

The use of a fibula osteocutaneous flap is currently the mainstay of segmental mandibular reconstruction. This type of flap is used to treat tumors, trauma, or osteoradionecrosis of the mandible. However, a fibula osteocutaneous flap may also be a good option for reconstructing the mandible to preserve oropharyngeal function and facial appearance in cases of pathological fracture requiring extensive segmental bone resection.
