Abstract
dc.description.abstract
The objective of this study was to assess the need for secondary orthognathic surgery in patients undergoing two different condylectomy protocols for active unilateral condylar hyperplasia (UCH). A retrospective cohort study evaluated UCH patients treated by condylectomy. Two groups were established: group 1 comprised those who had undergone a high condylectomy (5 mm removed) and group 2 comprised those who had undergone a proportional condylectomy (removing the difference observed between the measurements of the hyperplastic and the healthy side). Data analysis was done with the Levene test and t-test; a P-value of <0.05 indicated a statistically significant relationship. Forty-nine patients, with an average age of 19.83 years, were analyzed; 11 were included in group 1 and 38 in group 2. There was no statistical difference between the two groups with regard to age or sex (P = 0.781). An average of 5.81 mm was removed in the high condylectomy group:while an average of 9.28 mm was removed in the proportional condylectomy group; this difference was statistically significant (P = 0.042). Comparing the two groups, proportional condylectomy reduced the need for secondary orthognathic surgery (P < 0.001). The proportional condylectomy can be used as the sole surgical treatment in cases of UCH, thus avoiding the need for secondary orthognathic surgery.
The purpose of this study was to measure the changes in facial, occlusal, and
skeletal relationships in patients with active unilateral condylar hyperplasia whose
sole treatment was a low condylectomy. A retrospective ...
