Hard and soft tissue changes and long-term stability after vertical height reduction genioplasty using biodegradable fixation

The aim of this work was to analyse the stability of vertical height reduction genioplasty using biodegradable material, as well as to determine vertical changes of hard and soft tissues during this procedure.Forty patients underwent vertical height reduction genioplasty using two types of biodegradable fixation (Biosorb FX® or OSTEOTRANS-MX®), combined with mandibular setback surgery. We assessed lateral cephalographs over time (pre-operation; immediately post-operation; 3 months, 6 months and 12 months post-operation).
