In all the patients treated, the characteristics of the ultrasonic frequencies allowed rapid and easy intraoperative management, without any visible injury to the adjacent soft tissue. No side effects were detected.
The piezoelectric device is a new and revolutionary bony scalpel using the microvibrations at ultrasonic frequency so that soft tissue will not be damaged even on accidental contact with the cutting tip; this renders the piezoelectric device ideal for otologic bone surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
