Osteotomy in Genioplasty by Piezosurgery.

Area of Science:

• Oral and Maxillofacial Surgery
• Plastic Surgery
• Biomedical Engineering

Background:

• Genioplasty, a common procedure for chin deformities, aims to harmonize facial features.
• Traditional genioplasty techniques using saws and drills carry risks of immediate complications.
• The piezoelectric scalpel offers a novel approach to osteotomy in chin surgery.

Observation:

• Fifty-five patients underwent intraoral genioplasty between 2006 and 2008.
• Procedures involved osteotomies using a piezoelectric cutting device, with grafts used for stabilization when necessary.
• The piezoelectric scalpel was employed for various chin deformity corrections.

Findings:

• Piezosurgery demonstrated fewer postoperative complications, including reduced intraoperative bleeding, nerve injuries, hematomas, and asymmetry.
• The procedural time for genioplasty using piezosurgery was comparable to traditional saw and drill methods.
• The piezoelectric scalpel's selective cutting, precision, and cavitation effect minimize vascular and nerve damage.

Implications:

• The piezoelectric scalpel offers a safer and more precise method for genioplasty, reducing immediate surgical risks.
• This technology can lead to improved patient outcomes and satisfaction in chin augmentation and reconstruction.
• Adoption of piezosurgery in genioplasty may set a new standard for minimizing complications in facial bone surgery.
