Abstract
Introduction: A new piezoelectric surgical device, a new system for cutting bone system, has recently been developed. It uses lowfrequency
ultrasonic vibrations to shape and cut bone.
Case Presentation: In this paper, we report the case of a 70-year-old woman affected by (G2, T1, M0) oral cancer treated with osteotomy
performed using this piezoelectric device. The case presents the complete surgical excision of a fornix squamous cell carcinoma
in which the marginal mandibulectomy was effected by a piezoelectric system.
Conclusions: People who have conditions involving bone that need to be surgically removed specifically nearby soft tissues or
important structures (vessels, nerves, or brain), may benefit from this device. In the oral cavity, where the presence of essential
structures may hinder safe osteotomy, the piezoelectric device allows the surgeon to cut bone without damaging nerves, glands,
and vessels, even when in contact with them. The presence of angled inserts is also fundamental and facilitates osteotomies in areas
that are unreachable by conventional cutters and burs.
