[Condylo-pterygo-maxillo-oblique tomography].

This is a new projection method for TMJ examination. In this film, not only the structures of the joint but also the surrounding structures were manifested. These included the internal and external articular tubercles, internal and external poles of the condylar head, pterygoid process, and the posterior portion of dental occlusion. Particularly, the external pterygoid muscle is manifested in this film. The above mentioned features could not be found in Schüller's film. It is obvious that the combined CPMO tomography with Schüller's film will be a perfect method of TMJ examination. The details of the projection technique are described and discussed.
