Osteotomy in Genioplasty by Piezosurgery

Area of Science:

• Plastic Surgery
• Oral and Maxillofacial Surgery
• Medical Technology

Background:

• The chin's prominence is crucial for facial harmony.
• Traditional genioplasty carries risks of immediate complications.
• Piezoelectric scalpel offers a novel approach to chin deformity correction.

Purpose of the Study:

• To evaluate the efficacy of piezoelectric scalpel in chin surgery.
• To compare complication rates between piezoelectric and traditional genioplasty.
• To assess patient outcomes and satisfaction with piezoelectric chinplasty.

Main Methods:

• Fifty-five patients underwent intraoral chinplasty using a piezoelectric cutting device.
• Procedures were performed between January 2006 and April 2008.
• Osteotomies were performed with piezoelectric tools, with optional interpositional grafts for stabilization.

Main Results:

• Piezosurgery demonstrated fewer postoperative complications, including reduced intraoperative bleeding, nerve injuries, hematomas, seromas, and asymmetry.
• The procedure time using piezosurgery was comparable to traditional saw and drill methods.
• The piezoelectric scalpel provided a blood-free surgical site and enhanced precision.

Conclusions:

• Piezoelectric scalpel use in genioplasty minimizes immediate complications such as mental nerve injury and bleeding.
• The technology's microvibrations and cavitation effect reduce risks to vascular and nervous structures.
• This technique improves surgical precision and patient outcomes in chin augmentation and reconstruction.
