Frontal beak reduction remains one of the most technically demanding steps in endoscopic sinus surgery (ESS) for chronic rhinosinusitis. Conventional high-speed drills are widely used but may cause thermal injury and soft-tissue trauma, prompting interest in piezoelectric devices that enable selective ultrasonic bone cutting with greater precision. To address this, a study compared piezoelectric surgery with conventional drilling in 43 adults undergoing ESS.
While both procedures demonstrated significant post-operative improvements in Lund–Mackay and Sino-Nasal Outcomes Test (SNOT)-22 scores, the piezoelectric group achieved significantly lower Lund–Kennedy scores at week 1, indicating better mucosal healing. Notably, correlations between ostium dilatation and improved Lund–Mackay and SNOT-22 scores were observed in the piezoelectric group at 24 weeks. However, no significant…
