Summary

This study compares two types of chin surgery—Box genioplasty and Mini-Wing genioplasty—in adults with a receding lower jaw (skeletal Class II deformity) who are also having jaw realignment surgery. The goal is to see which technique better improves the upper airway size and the soft-tissue profile of the chin and neck. By measuring changes on CT scans taken before and six months after surgery, researchers hope to determine whether one method offers superior functional and cosmetic results.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Mini Wing genioplasty or Box genioplasty (surgical procedures on the chin bone)
What this could lead to
If one technique proves superior, it could guide surgeons toward a standard approach that improves both breathing and facial profile for patients with jaw deformities.
What could go wrong
This is a small retrospective study, so results may not apply to all patients. Surgery carries risks like infection, nerve damage, and swelling.
