BACKGROUND – Temporomandibular dysfunction is the most common cause of chronic orofacial pain. Modified condylotomy may be indicated in discus dysfunction of the temporomandibular joint, where conservative treatment was insufficient. Modified condylotomy was first described in 1989.
MATERIAL AND METHOD – From 2000 to 2018, 31 patients were treated with uni- or bilateral modified condylotomy. Retrospectively, mouth opening, pain, headache and complications were evaluated.
RESULTS – Twenty-nine patients were treated with unilateral modified condylotomy, and two patients were treated with bilateral modified condylotomy at Department of Oral and Maxillofacial Surgery, Aalborg University Hospital, Denmark. All patients were diagnosed with discus dysfunction had been through conservative treatment without sufficient effect. The post-operative control period was 18.7 15.9 months. Pain decreased statistical significant after treatment with modified condylotomy (P = 0,000). In addition, the maximum jaw opening was statistical significantly increased postoperatively (P = 0,000). Six patients developed paraesthesia of the buccal nerve and one patient developed paraesthesia of alveolar inferior nerve. Additional complications did not occur.
CONCLUSION – Modified condylotomy for the treatment of discus dysfunction of the temporomandibular joint is an alternative treatment option to intraarticular surgery when conservative treatment is insufficient. The procedure results in a reduction in pain intensity and an increase in maximum jaw opening.
