Artroscopic surgery of the TMJ has been a successful mode of surgery.Eliminating the need for physical contact with the diseased tissue the trauma to surrounding synovial tissue and articular cartilage. Laser use can also provide rapid coagulation with minimal thermal damage allowing better visualization of the surgical field and decreased hemarthrosis. Laser surgery is much more precise and can be more easily manipulated in the narrow joint space. The Ho:YAG laser is minimally absorbed by water and therefore transmits its energy directly to the desired tissue. Arthroscopic procedures are typically performed under general anaesthesia with naso tracheal intubation. Procedures such as diskectomy,diskoplasty, synovectomy, hemostasis, posterior attachment contraction, anterior release and debridement of fibrous ankylosis can be performed.
