2022 AAO Annual Session - Assessment of Soft Tissue Changes Versus Hard Tissue Following a Functional Genioplasty as an Isolated Procedure

May 22, 2022 9:45am ‐ May 22, 2022 10:15am

Credits: None available.

Standard: $30.00


The aim of this study is to determine the vertical and horizontal soft tissue change versus hard tissue change following isolated functional genioplasty and to revisit hard tissue remodeling at the symphysis. The predictive model reveals that soft tissue change can be predicted with more precision horizontally than vertically. For non-growing patients, the horizontal hard tissue change is stable, and the soft tissue change is 92% of the hard tissue changes. Vertically, the soft tissue change is less predictable. Prediction equations have been calculated. The soft tissue thickness variations after genioplasty in both directions can be explained by skeletal changes and the achievement of an unforced labial occlusion. These results support the functional and aesthetic benefit of this surgery.

Learning Objectives:

  • Understand the indication and surgical planning for a functional genioplasty.
  • Evaluate the short- and long-term soft tissue changes following hard tissue change and the relationship with post up swelling.
  • Evaluate the bone remodeling and long term functional and esthetic change following a functional genioplasty as an isolated procedure.
