A study of surgical treatment for unilateral anterior disc displacement without reduction

Objective To preliminarily evaluate the surgical treatment for anterior disc displacement without reduction (ADDwR) . Methods Fifty-four patients with ADDwR received disc repositioning and fixation via open anchorage surgery from October 2012 to October 2013 were enrolled. They were distributed into three groups according to the course of disease: 12 months (17 cases) . The follow-up time was 1-12 months and the clinical effects of each group were compared. Results The postoperative clinical effect was significantly improved, such as maximum interincisal opening (MIO) and pain release (P 12 m (P 12 m (P < 0.05) . Conclusions With the accurate diagnosis and appropriate selection of indications, disc repositioning and fixation via open anchorage surgery should be an effective procedure for ADDwR, especially in the cases treated within 12 months. Earlier treatment means better prognosis. Key words: Temporomandibular disorders; Anterior disc displacement without reduction; Disc anchorage
