Summary
This study details planning corrective genioplasty for asymmetric chins, especially with bimaxillary orthognathic surgery. It highlights geometric considerations for precise surgical outcomes in complex cases.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Plastic Surgery
Background:
- Genioplasty (sliding osteotomy of the inferior border of the mandible) is well-documented for symmetrical cases.
- Treatment planning for asymmetric chins, particularly with orthognathic surgery, lacks detailed literature.
- Correcting complex chin asymmetry alongside bimaxillary orthognathic surgery presents significant surgical challenges.
Observation:
- Asymmetric chin correction requires meticulous diagnosis and treatment planning.
- Geometric considerations are crucial for planning corrective genioplasty in asymmetric cases.
- A systematic protocol involving data collection and model surgery aids in planning.
Findings:
- The article presents a protocol for planning corrective genioplasty in asymmetric chin cases.
- It emphasizes geometric principles for achieving millimetric precision.
- A case presentation demonstrates successful application in a patient undergoing orthognathic surgery.
Implications:
- This work addresses a gap in the literature regarding complex asymmetric chin correction.
- It provides a framework for surgeons tackling challenging combined procedures.
- The findings suggest that precise planning can lead to predictable, aesthetic outcomes in complex genioplasty cases.
