These fresh cadaver dissections start with an incision across the zygomatic arch and continue to expose the subcutaneous layers and their arteries nerves and veins. Superficial access to the TM joint is demonstrated and the hazards of damaging the facial nerve directly over the lateral pole of the joint. The attachments of the superior fibers of the lateral pterygoid muscle to the disc and or the condyle is demonstrated. A new disc attachment at the medial of the joint is demonstrated as well as a logical ,anatomical reason for disc displacement. A highlight of this Video/CD-Rom is the section demonstrating TM joint arthrokinematics. This and how the structures function throughout the opening and closing movements.
