Objective.
The purpose of this study was to investigate postoperative stability and the correlation between hyoid, tongue, and mandible position following surgery for mandibular prognathism.
Materials and Methods.
Thirty-seven patients, treated for mandibular prognathism using intraoral vertical ramus osteotomy (IVRO), were evaluated cephalometrically.
A set of four standardized lateral cephalograms were obtained from each subject preoperatively (T1), immediately postoperatively (T2), six weeks to three months postoperatively (T3), and more than one year postoperatively (T4).
The Student t-tests, the Pearson correlation coefficient, and the multiple linear regression were used for statistical analysis.
Results.
Immediately after surgery, menton (Me) setback was 12.8 mm, hyoid (H) setback was 4.9 mm, and vallecula epiglottica (V) setback was 5.8 mm.
The postoperative stability significantly correlated (r=-0.512, p<0.01) with the amount of setback.
The hyoid bone and tongue did not have significant effects on postoperative stability.
Multiple linear regression model (R2=0.2658, p<0.05) showed predictability: Horizontal Relapse Me (T4-T2) = −6.406 − 0.488Me (T2-T1) + 0.069H (T2-T1) − 0.0619V (T2-T1).
Conclusion.
Mandibular setback surgery may push the hyoid and tongue significantly backward, but this did not correlate with mandibular relapse.
Postoperative stability significantly correlated with the amount of mandibular setback.
