TMJ joint surgery in Delhi has become a destination for medical tourism from all parts of the world. The cost of temporomandibular joint surgery in Delhi is a fraction of what it costs in the west. Many patients from western countries combine a holiday with their surgery. It is because of India's excellent reputation for offering quality surgical care. TMJ arthroscopy is used to diagnose TMJ disorder. During this procedure, your surgeon will insert a thin tube called a cannula into the joint area. A small camera, the arthroscope, is put inside to view the area and help to diagnose the condition.
