暂无{Abstract}: <B>OBJECTIVE: </B>The aim of this study was to evaluate the safety and efficacy of the piezoelectric knife as a new tool for frontal beak surgery in patients with chronic rhinosinusitis (CRS) both in terms of imaging and perception of symptoms' outcomes.<BR><B>METHODS: </B>The study involved 28 patients with CRS who underwent endoscopic sinus surgery (ESS) using a piezoelectric knife in the frontal recess region. Assessment of sinus imaging and patients' quality of life (QoL) was performed before and after surgery with the Lund-Kennedy and Lund-Mackay systems and the 22-item Sino-Nasal Outcomes Test (SNOT-22).<BR><B>RESULTS: </B>Median scores on the Lund-Kennedy and Lund-Mackay systems decreased within 24 weeks after surgery with piezo knife assistance by 4 and 5 points, respectively. QoL improved with SNOT-22 scores decreasing by 35.5 points.<BR><B>CONCLUSIONS: </B>ESS with the piezoelectric knife used for frontal beak reduction turned out to be a safe procedure. In the studied group of patients, the improvement was observed in terms of imaging, patients' perceptions of symptoms, and QoL outcomes. Therefore, the piezoelectric knife might be a valuable supporting tool in ESS in patients with CRS, although further observation is needed.
