Efficacy and safety of piezosurgery device in the surgical treatment of oral cancer

ntroduction: A new piezoelectric surgical device, a new system for cutting bone system, has recently been developed. It uses low- frequency 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 os- teotomy performed using this piezoelectric device. The case presents the complete surgical excision of a fornix squamous cell car- cinoma 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.
