Condylotomy for Treatment of Temporomandibular Joint Disorders

Condylotomy for Treatment of Temporomandibular Joint Disorders

The condylotomy is an osteotomy completed in a manner identical to the vertical ramus osteotomy described in  Chapter 25. When used fot treatment of TMJ problemsthe osteotomyis completed, but 110 wireor screw fixation is placed, and the patient is placed into intermaxillary fixation for a period ranging from 2 to 6 weeks. The the ory behind this operation is that muscles attached to the proximal segment (i.e., segment attached to the condyle)
will passively reposition the condyle, resulting in a more favorable relationship between the condyle, disk, andfossa.33 This technique has been advocated primarily for treatment of disk displacement with or without reduction. DJD and subluxation or dislocation have also been suggested
as possible indications for use of this technique .Although this method of surgical treatment has been somewhat controversial, it appears to provide significant clinical improvement in a variety of TMJ disorders.
