Abstract [en]

The aim of this study was to retrospectively analyze the outcome of patients operated with discectomy and to compare the short-term findings to already existing results in literature. 64 patients who underwent discectomy at the Department of Oral and Maxillofacial surgery, Umeå University hospital in Sweden, between 1988 and 1998 were included. The mean age was 37 years. 55 of the patients were women and 9 were men. 48 patients underwent unilateral surgery and 16 patients underwent bilateral surgery (14 women/2 men). Six months after the surgery, 70 % of the patients reported no pain from the temporomandibular joint area, compared to 10 % prior to surgery (P-value < 0.001). The patients had a mean opening of 36,7 mm before surgery and a mean opening of 41,8 mm after surgery (P-value = 0.001). TMJ crepitation was found in 36 % of the joints before surgery respectively 34 % of the joints six months after surgery (P-value = 0.125). TMJ clicking was found in 43 % joints before surgery, and in 6 % after surgery (P-value < 0.001). Locking occurred in 59 % of the TMJ prior to surgery and in 11 % after surgery (P-value < 0.001). Surgical removal of the disc in the temporomandibular joint reduces pain and increases mouth opening. The result from our study is consistent with other studies and recognizes discectomy as an effective treatment of persistent pain and/or limitation of mouth opening.
