Summary
Piezosurgery, a novel ultrasonic bone cutting tool, demonstrated excellent control and safety in nasal tumor surgery. This innovative technique minimizes damage to surrounding soft tissues, offering a revolutionary approach for osteotomy procedures.
Area of Science:
- Otolaryngology
- Surgical Technology
- Oncology
Background:
- Piezosurgery is an emerging technology for bone cutting.
- It utilizes ultrasonic frequencies to minimize damage to non-mineralized tissues.
- Its application in nasal surgery has not been extensively studied.
Purpose of the Study:
- To evaluate the efficacy and safety of Piezosurgery as a bony scalpel in nasal surgery.
- To assess its performance in the excision of malignant nasal tumors.
Main Methods:
- A nonrandomized study involving 10 patients with nasal adenocarcinoma.
- Piezosurgery was employed via a paralateronasal approach for tumor excision.
- The piezoelectric device operated at low-frequency ultrasonic waves (24.7-29.5 kHz) with adjustable power.
Main Results:
- Piezosurgery provided excellent surgical control in all cases.
- No bleeding or harmful effects on adjacent structures were observed.
- No adverse events were reported by any of the patients.
Conclusions:
- Piezosurgery is a safe and effective osteotomy technique for nasal surgery.
- Its ultrasonic microvibrations protect soft tissues from inadvertent damage.
- The device is ideal for nasal tumor excision due to its precision and safety profile.
