目的认为SARS-CoV-2的主要传播方式是通过呼吸道飞沫传播。本研究的目的是调查由普通内镜内镜手术引起的液滴和飞溅模式。研究设计：尸体模拟系列。专门的外科实验室。实验对象和方法将2例尸体头部标本灌注荧光素溶液后，系统地进行内镜下鼻内操作，评估每个实验条件下液滴和飞溅的数量、大小和距离。结果鼻内窥镜检查、鼻中隔成形术（微清鼻翼辅助成形术）、冷钢功能内镜鼻窦手术（FESS）和超声吸引器的所有实验条件下，均未观察到荧光素液滴或飞溅。微清氧剂FESS(2滴，
ObjectiveThe primary mode of viral transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is thought to occur through the spread of respiratory droplets. The objective of this study was to investigate droplet and splatter patterns resulting from common endoscopic endonasal procedures.Study DesignCadaver simulation series.SettingDedicated surgical laboratory.Subjects and MethodsAfter instilling cadaver head specimens (n = 2) with fluorescein solution, endoscopic endonasal procedures were systematically performed to evaluate the quantity, size, and distance of droplets and splatter following each experimental condition.ResultsThere were no observable fluorescein droplets or splatter noted in the measured surgical field in any direction after nasal endoscopy, septoplasty with microdebrider-assisted turbinoplasty, cold-steel functional endoscopic sinus surgery (FESS), and all experimental conditions using an ultrasonic aspirator. Limited droplet spread was noted with microdebrider FESS (2 droplets,
