Independent risk factors for long-term skeletal relapse after mandibular advancement with bilateral sagittal split osteotomy

Independent risk factors for long-term skeletal relapse after mandibular advancement with bilateral sagittal split osteotomy: The purpose of this retrospective cohort study was to identify the independent risk factors for long-term skeletal relapse following mandibular advancement with bilateral sagittal split osteotomy. Univariate and multivariate linear regression analyses were performed including nine common risk factors for relapse as independent variables and horizontal/vertical long-term (≥2 years) skeletal relapse as dependent variables. Ninety-six patients were analyzed; 66 were female (68.8%) and the average age of the patients was 29.7±10.5 years.
