Summary

Genioplasty surgery outcomes vary. Anterior chin repositioning showed predictable soft tissue results, unlike posterior or vertical chin reduction procedures.

Area of Science:

Aesthetic Surgery

Background:

Genioplasty, a surgical procedure to alter the chin, involves bone repositioning.
Understanding soft tissue response is crucial for predicting aesthetic outcomes.

Purpose of the Study:

To evaluate the soft tissue response following different genioplasty techniques.
To assess the predictability of soft tissue changes in relation to bone movement.

Main Methods:

A study involving 65 patients undergoing genioplasty.
Patients were categorized into four groups based on surgical direction: anterior, posterior, vertical reduction, and superior-anterior repositioning.

Main Results:

Soft tissue response predictability varied across genioplasty types.
Anterior repositioning demonstrated soft tissue changes closely matching bone movement.
Posterior repositioning and combined vertical reduction showed less predictable soft tissue outcomes.

Conclusions:

The predictability of soft tissue response in genioplasty is direction-dependent.
Anterior genioplasty offers more predictable soft tissue results compared to other techniques.
