Because of its superior depiction of bone detail, CT is a useful tool in the characterization of CF deformities and presurgical planning. Modern CT scanners and workstations provide 2D techniques such as multiplanar reformats and 3D techniques, such as MIP and volume renderings, which may be used effectively in the diagnosis and management of patients with CF malformations.

ReviewMalignant tumors of the oral cavity and oropharynx: clinical, pathologic, and radiologic evaluation.
Carcinomas of the oral cavity and oropharynx constitute approximately 2% to 5% of head and neck cancers. Alcohol abuse and tobacco chewing, including chewing Shamma, predispose individuals to the development of cancer in the oral cavity. CT and MR imaging are best suited in the evaluation of cancer of the oral cavity and oropharynx. ⋯ Some malignant lesions may mimic a benign tumor, such as the adenoid cystic or mucoepidermoid carcinoma. Histopathologic diagnosis is therefore necessary for the final diagnosis before treatment by surgery or radiotherapy. PET scanning is indicated in the following instances: in search of an unknown primary tumor in patients who have a neck mass secondary to carcinoma, if a recurrent carcinoma may be present, when there are metastatic N0 lymph nodes in the neck, or where CT is inconclusive for metastatic lymph nodes in the neck.

Diagnostic imaging of TMJ has improved remarkably in the last 20 years. Various abnormalities related patient symptoms. Further studies using the latest imaging techniques will allow a better understanding of the sources of joint pain and the discrepancy between imaging findings and patient symptoms. For clinical practice, appropriate clinical examinations are needed to determine exactly which imaging findings are significant.

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.

ReviewLesions of the maxilla: crossroads of the head and neck.
The maxilla may be involved by a wide range of pathologic conditions. Lesions originating in the maxilla may involve the adjacent orbit, oral cavity, or retroantral spaces. Recognition of this relationship plays an important role in diagnosis, prognosis, and presurgical planning.
