Piezoelectric surgical units operate with a vibration in the range of 25 to 35 KHz, offering several advantages including high precision, selective cutting of bone while limiting damage to the surrounding soft tissues, less trauma to neurovascular tissues, reduced hemorrhage, and improved healing. Manual bone-cutting instruments operate at a high speed and can lead to thermal injury to the bone, severe damage to blood vessels, nerves, and soft tissues, and increased pain following bone surgery. This step-by-step manuscript describes the use of a piezoelectric surgical unit to perform a segmental (central) maxillectomy.
