30° tilt axial computed tomography imaging of the facial skeleton: Pathologic conditions Academic Article uri icon

abstract

  • The nasal cavity, paranasal sinuses, and the craniofacial junction are an anatomic region in which a variety of congenital, inflammatory, neoplastic, and traumatic lesions occur. Computed tomography (CT) has proved to be valuable in the detection of bone and soft tissue involvement. Contiguous axial and coronal sections are required for proper examinations. However, direct biplane imaging is not desirable in cases of injuries to the cervical spine, cervical degenerative changes, and respiratory failure. 30° tilt axial CT imaging combines axial and coronal incidences, and provides an accurate evaluation of soft tissue and bone. The procedure is done in one setting with the patient supine and without the need of computerized reconstruction. This imaging technique will be described with reference to various clinical conditions that involve the facial skeleton and skull base, and especially in cases of complicated craniofacial trauma.
