Real-time endoarticular ultrasound imaging of the TMJ--a new diagnostic possibility? A cadaver study.

Recent advances in ultrasound imaging suggested endoarticular ultrasound imaging of the temporomandibular joint (TMJ) in combination with TMJ-arthroscopy as a new diagnostic method. Our investigations were performed on human cadavers, in combination with traditional TMJ-arthroscopy. During our investigations, the main articular structures were identified: the glenoid fossa of the temporal bone, articular disc, condyle of the mandible, and retrodiscal tissue. The combination of arthroscopy and ultrasound imaging provides more information on position, movement, and pathological changes in joint structures. Although all of the advantages, disadvantages, indications, and complications of this new diagnostic procedure are not yet clear, the authors consider this new method a useful diagnostic procedure for TMJ imaging.
