Abstract
We sought to evaluate the relation of orthognathic surgery and temporomandibular disorders symptoms in patients who performed bilateral sagittal split ramus osteotomy. 111 patients underwent bilateral sagittal split ramus osteotomy in the department of oral and maxillofacial surgery in Chosun University Dental Hospital. Patients were classified according to with or without symptoms before surgery and after surgery, types of temporomandibular disorders symptoms, and the degree of setback. Twelve (16.9%) out of 71 patients presented with clicking sounds and tenderness of temporomandibular joint in no symptom group before surgery, whereas seven (17.5%) out of 40 patients were worsened temporomandibular disorders in symptom group before surgery. The improvement of temporomandibular disorders by the treatment of malocclusion brings a favorable turn in most cases. However, the change for the worse or new symptoms can occur in the small number of patients. So, more investigations over the risk factors and advantages of orthognathic surgery are needed to clearly evaluate the effects on the temporomandibular disorders.
