ReviewThe temporomandibular joint: clinical and surgical aspects.
Advances in imaging techniques have greatly enhanced the ability to visualize the internal anatomy of the temporomandibular joint and have increased understanding of the etiology of many temporomandibular disorders. When used together with careful history and physical examination, this knowledge can contribute to better treatment outcomes.

Vascular interventions are important and helpful for treatment of various pathologies of the head and neck. Interventional neuroradiology of the head and neck includes image-guided biopsies, vessel occlusion, and local chemotherapy. Knowledge of anatomy, functional relationships between intra- and extracranial vessels, and pathology are the basis for therapeutic success. ⋯ Avoiding complications, handling unavoidable problems, and dealing with complications is a skill founded on knowledge and experience. Continuing education is a firm basis to push the limits of interventions and expand benefits without increasing risk for the patient. Nevertheless, state-of-the-art external carotid intervention should, in skilled hands, have a permanent morbidity far below 1% and no mortality.

Malignant tumors of the mandible and maxilla are grouped into primary tumors that originate within the mandible and secondary lesions, predominantly oral cancers and metastatic lesions, that involve the mandible secondarily. The most common malignant tumors of the mandible represent SCCs of the oral cavity, notably carcinoma of the floor of the mouth and gingiva that invade the mandible secondarily. Metastatic disease, most commonly from the breast and lung, are not an uncommon malignant lesion in the mandible and may be the first manifestation of a malignant lesion outside the head and neck. ⋯ CT is indicated for assessment of bone destruction in the mandible before surgery or radiation therapy. MR imaging is the optimal modality for the assessment of marrow involvement and evaluation of the extraosseous soft tissue component. Finally, conventional films, frequently a Panorex view, are the initial radiographic examinations in suspected lesions.

ReviewCysts and tumors of the oral cavity, oropharynx, and nasopharynx in children.
A wide variety of developmental and neoplastic lesions arise in the oral cavity, oropharynx, and nasopharynx in children. The clinical manifestations and cross-sectional imaging findings provide complementary information, which is used to establish a probable or definitive diagnosis. This article describes imaging techniques and findings for developmental cystic masses and solid tumors in the pediatric population.
