Abstract

The main objective of this study was to evaluate long-term stability of rigid osteosynthesis in the context of advancement genioplasty.

Bone stability was defined as a long-term bone loss of less than 2 mm. Measurements were performed on lateral cephalograms, in the sagittal and vertical planes, at three times: preoperative (T0, less than one month before surgery), early postoperative (T1, at least one month post-operatively) and late postoperative (T2, at least one year after surgery).

25 patients were included in the study, with a mean follow-up of 3.47 years (range 1–9.42 years). The mean sagittal bone advancement at T1 was 4.06 mm ± 1.34, with a bone loss of 0.65 mm at T2 (p = 0.001). The mean vertical bone movement was 1.25 mm ± 0.47 at T1, with a relapse at T2 of 0.34 mm (p = 0.27). The soft-to-hard tissue ratio was 78% in the sagittal plane.

Rigid osteosynthesis offers long-term stability, with very little change in clinical outcome, in advanced genioplasty.
