Temporomandibular joint arthrography without fluoroscopy

Panoramic radiography for temporomandibular joint arthrography: a description of arthropanoramograms

TMJ arthrograms done with panoramic radiography, i.e., arthropanoramography, can demonstrate intracapsular disk displacement and perforation pathoses. These views are very practical for inferior synovial cavity arthrograms performed in the dental operatory since panoramic radiographic machines have become common in modern dental practices. Specific advantages of arthropanoramography include the decreased financial cost and decreased radiation exposure to the patient. Arthropanoramography does not replace tomography or videofluoroscopy in TMJ arthrography. It is, however, described as a simple alternative to the more conventional forms of arthrography.

Temporomandibular joint arthrography: a comparison between a fluoroscopic and a nonfluoroscopic technique

A nonfluoroscopic temporomandibular joint arthrographic technique is contrasted with a more widely employed fluoroscopically guided technique. The nonfluoroscopic technique uses a posterior approach to joint injection, as contrasted with the lateral injection approach of the fluoroscopically guided technique. The advantages of the nonfluoroscopic technique are less radiation dose to the patient, less expensive and less sophisticated imaging equipment, and less potential for neurovascular trauma. The fluoroscopic technique offers greater control of the procedure, less patient and operator time, and the capability for a dynamic videofluoroscopic study. Both techniques appear to be safe and efficacious. Differences in anatomy, imaging modalities, patient radiation exposure, and potential complications are also discussed as part of this comparison.
