Summary
Mandibular advancement surgery significantly improves facial profiles by straightening skeletal and soft tissues. Soft tissue changes closely follow bone movement, enhancing lower lip posture and overall facial aesthetics.
Area of Science:
- Orthodontics and Dentofacial Orthopedics
- Plastic Surgery
- Cephalometric Analysis
Context:
- Mandibular retrognathism often requires surgical correction.
- Combined orthodontic and surgical approaches are common.
- Predicting soft tissue response to skeletal changes is crucial.
Purpose:
- To analyze soft and dentoskeletal tissue relationships after mandibular advancement.
- To identify cephalometric predictors for surgical outcomes.
- To evaluate changes in facial profile and lip morphology.
Summary:
- Cephalometric analysis of 14 patients undergoing bilateral sagittal split osteotomy for mandibular advancement.
- Skeletal and soft tissue landmarks were measured pre- and post-surgery.
- Statistical analysis (t-tests, correlation, regression) assessed profile changes.
Impact:
- Mandibular advancement osteotomy resulted in significant facial profile improvement.
- Soft tissue movements corresponded closely to skeletal changes (59-122%).
- Improved lower lip posture and a straighter facial profile were observed.
