Genioplasty is a surgical procedure performed to reshape or reposition the chin. It is commonly done to correct chin deformities, improve facial aesthetics, or address functional issues such as airway obstruction. Genioplasty can be classified into two main types: sliding genioplasty and augmentation genioplasty.

Sliding Genioplasty

Sliding genioplasty is an osteotomy procedure where the chin bone (mandibular symphysis) is cut and repositioned. This technique is especially beneficial for:

• Chin advancement (for a retruded chin)

• Chin setback (for a prominent chin)

• Vertical lengthening or shortening

• Asymmetry correction

Key Techniques for Sliding Genioplasty:

1. Precise Osteotomy Location:

• The osteotomy is typically performed below the mental nerve for nerve preservation.

• Using an oscillating saw ensures a straight and accurate cut.

2. Fixation Techniques:

• Plates and screws are commonly used for stabilization.

• Miniplates or locking plates enhance stability and minimize relapse.

3. Soft Tissue Considerations:

• Tension-free closure to reduce the risk of chin ptosis.

• Adequate release of the periosteum to maintain chin projection.

4. Planning and Simulation:

• Preoperative imaging (CBCT or CT scans) and virtual surgical planning help optimize outcomes.

Important Considerations and Pearls:

• Symmetry Assessment: Preoperative facial analysis is crucial for determining the degree of advancement or augmentation.

• Occlusion and Airway: Addressing occlusal changes and ensuring airway patency are vital.

• Postoperative Monitoring: Early detection of hematoma or nerve injury reduces complications.

• Combining with Other Procedures: Often performed with rhinoplasty or orthognathic surgery for comprehensive facial harmonization.
