Comparison of genioplasty using Medpor and osteotomy.
OBJECTIVE
This retrospective study compared genioplasty using Medpor with osteotomy by measuring the amount of anteroposterior change in hard and soft tissue.


METHODS
Thirty-three patients who underwent mentum augmentation and who were followed-up >6 months were included. Subjects were divided into 2 groups: group A, with 14 patients who underwent genioplasty using osteotomy; and group B, with 19 patients who underwent genioplasty using Medpor. Patients chose one of the treatments themselves.


RESULTS
The mean relapse rate of the most prominent or anterior point on the chin in the midsagittal plane of patients who went underwent osteotomy was 18.59%, and the mean relapse rate of patients who went underwent genioplasty with Medpor was 14.56%.


CONCLUSIONS
It was found that the amount of the movement at the time of surgery when checked after surgery did not change in patients who underwent genioplasty using Medpor compared with patients who underwent genioplasty using osteotomy.
