The authors prospectively analysed 50 patients with chronic anterior disc displacement without reduction, who underwent arthroscopic lysis and lavage of the temporomandibular joint (TMJ). Patients with symptoms lasting less than 1 year were assigned to Group A (n = 28) and patients with symptoms lasting more than 1 year to Group B (n = 22). The most common problems were inflammatory changes of synovial and retrodiscal tissue (Group A, 71%; Group B, 82%). Fibrous adhesions were present in 14% of Group A patients and 45% of Group B patients. Degenerative changes of the disc and articular surface were present in 4% of Group A patients and 32% of Group B patients. Mouth opening increased 123% from baseline in Group A, and 112% in Group B (P < 0.05). Pain decreased significantly in both groups (Group A, 2.5 points; Group B, 1.68 points; P < 0.05). In conclusion, almost all patients with chronic anterior disc displacement without reduction benefited from arthroscopic lysis and lavage of the TMJ. Patients with a shorter duration of symptoms problems benefited more than those with a longer duration. Arthroscopic lysis and lavage of the TMJ is safe and beneficial in chronic anterior disc displacement without reduction.
