Abstract：
OBJECTIVE: 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.
METHODS: 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).
RESULTS: 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.
CONCLUSIONS: 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.

摘要：
目的：本研究的目的是评估压电刀作为慢性鼻-鼻窦炎（CRS）患者额喙手术的新工具的安全性和有效性，包括影像学和对症状的感知结果。
方法：该研究涉及28例CRS患者，他们在额隐窝区域使用压电刀进行了内窥镜鼻窦手术（ESS）。在手术前后使用Lund-Kennedy和Lund-Mackay系统以及22项鼻窦结果测试（SNOT-22）进行鼻窦成像和患者生活质量（QoL）评估。
结果：在使用压电刀辅助的手术后24周内，Lund-Kennedy和Lund-Mackay系统的中位数得分降低了4分和5分，分别。QoL改善，SNOT-22得分下降35.5分。
结论：使用压电刀进行正面喙复位的ESS被证明是一种安全的手术。在研究的患者组中，在成像方面观察到改善，患者对症状的感知，和QoL结果。因此,压电刀可能是CRS患者ESS中一种有价值的支持工具，尽管需要进一步观察。
