Summary: | Background/Aim. Postoperative condylar position is a substantial concern in
surgical correction of mandibular prognathism. Orthognathic surgery may
change condylar position and this is considered a contributing factor for
early skeletal relapse and the induction of temporomandibular disorders. The
purpose of this study was to evaluate changes in condylar position, and to
correlate angular skeletal measurements following bimaxillary surgery.
Methods. On profile teleradiographs of 21 patients with mandibular angular
and linear parametres, the changes in condylar position, were measured during
preoperative orthodontic treatment and 6 months after the surgical treatment.
Results. A statistically significant difference in values between the groups
was found. The most distal point on the head of condyle point (DI) moved
backward for 1.38 mm (p = 0.02), and the point of center of collum mandibulae
point (DC) moved backward for 1.52 mm (p = 0.007). The amount of upward
movement of the point DI was 1.62 mm (p = 0.04). Conclusion. In the patients
with mandibular prognathism, the condyles tend to migrate upward and forward
six months after bimaxillary surgery. |
