Shortening and lengthening the chin

Area of Science:

• Oral and Maxillofacial Surgery
• Plastic Surgery
• Aesthetic Surgery

Background:

• Altering the vertical dimension of the chin is a common procedure in reconstructive and aesthetic surgery.
• Traditional methods for chin augmentation or reduction have varying degrees of success and predictability.

Purpose of the Study:

• To discuss methods for modifying the chin's vertical dimension.
• To highlight advancements in chin lengthening techniques.

Main Methods:

• Review of surgical techniques for chin vertical dimension alteration.
• Discussion of bone grafting materials and fixation methods.

Main Results:

• Miniplate fixation has significantly improved the results of chin lengthening procedures.
• The current preferred technique involves interpositional bone grafting from the outer table of the calvarium.

Conclusions:

• Chin lengthening can be reliably achieved with modern surgical techniques.
• Calvarial bone grafting combined with miniplate fixation represents the state-of-the-art for chin augmentation.
