Piezosurgery
Pronunciation: pee-ay-zo-SUR-jer-ee
An ultrasonic bone-cutting technique that uses microvibrations to selectively cut mineralised tissue while preserving adjacent soft tissues such as nerves and blood vessels.
Full Definition
Piezosurgery is a modern surgical modality employing ultrasonic vibrations at a specific frequency (24–29 kHz) to selectively cavitate and cut calcified hard tissues, such as bone and calculus, while leaving soft tissues — including nerves, blood vessels, and mucosa — largely unaffected due to the cavitation effect. In oral and maxillofacial surgery, it is used for sensitive procedures near neurovascular structures, including inferior alveolar nerve repositioning, sinus membrane elevation, and crestal osteotomies. Editors will encounter the proprietary brand name 'Piezotome' in operative notes; this should be genericised to 'piezoelectric device' or 'ultrasonic bone instrument' in academic publications unless brand citation is required. 'Piezosurgery' itself is a registered trademark of Mectron Medical Technology and should be capitalised accordingly in commercial contexts.
Usage
Usage note: 'Piezosurgery' is a registered trademark; in academic writing, prefer 'piezoelectric surgery' or describe the instrument generically. Capitalise if used in a proprietary context.
In Context
- "The surgeon elected to use piezosurgery for the crestal osteotomy to minimize the risk of Schneiderian membrane perforation during the transcrestal sinus lift." — Operative Report
- "The editor replaced the proprietary term 'Piezotome' with 'piezoelectric ultrasonic device' throughout the manuscript in accordance with the journal's genericisation policy." — Journal Manuscript Editing
