Segmental (Central) Maxillectomy Using a Piezoelectric Surgery Unit in a Dog.

Area of Science:

• Oral and Maxillofacial Surgery
• Biomedical Engineering
• Surgical Technology

Background:

• Traditional manual bone-cutting instruments risk thermal injury and damage to vital structures.
• Piezoelectric surgical units (PSUs) utilize ultrasonic vibrations (25-35 KHz) for precise osteotomies.
• PSUs offer advantages like selective cutting, reduced neurovascular trauma, and minimized hemorrhage.

Purpose of the Study:

• To describe the step-by-step application of a piezoelectric surgical unit for segmental (central) maxillectomy.
• To highlight the benefits of PSUs in complex maxillofacial procedures.

Main Methods:

• Detailed procedural description of segmental maxillectomy using a PSU.
• Focus on the precise osteotomy and tissue-sparing capabilities of the piezoelectric device.

Main Results:

• Demonstration of selective bone cutting with preservation of adjacent soft tissues.
• Reduced intraoperative bleeding and trauma to neurovascular bundles.
• Facilitation of a less invasive surgical approach for maxillectomy.

Conclusions:

• Piezoelectric surgical units provide a safe and effective method for segmental maxillectomy.
• PSUs enhance surgical precision, minimize collateral damage, and potentially improve patient recovery in maxillofacial surgery.
