The coronavirus disease 2019 pandemic has led to concerns over transmission risk from head and neck operations including facial cosmetic surgeries. To quantify droplet and aerosol generation from rhinoplasty techniques in a human anatomic specimen model using fluorescein staining and an optical particle sizer. Noses of human anatomic specimens were infiltrated using 0.1% fluorescein. Droplets and aerosols were measured during rhinoplasty techniques including opening the skin-soft tissue envelope, monopolar electrocautery, endonasal rasping, endonasal osteotomy, and percutaneous osteotomy. No visible droplet contamination was observed for any rhinoplasty techniques investigated. Compared with the negative control of anterior rhinoscopy, total 0.300-10.000 μm aerosols were increased after monopolar electrocautery ( < 0.001) and endonasal rasp ( = 0.003). Opening the skin-soft tissue envelope, endonasal osteotomies, and percutaneous osteotomies did not generate a detectable increase in aerosols ( > 0.15). In this investigation, droplets were not observed under ultraviolet light, and aerosol generation was noted only with cautery and endonasal rasping.
2019 年冠状病毒病大流行引发了人们对包括面部整容手术在内的头颈部手术传播风险的关注。本研究旨在使用荧光染色和光粒子计数器，在人体解剖标本模型中量化鼻整形术中的飞沫和气溶胶产生情况。使用 0.1%荧光素对人体解剖标本的鼻子进行渗透。在鼻整形术中测量了包括打开皮肤-软组织包膜、单极电凝、经鼻刮除、经鼻截骨和经皮截骨在内的技术产生的飞沫和气溶胶。未观察到任何鼻整形技术有可见的飞沫污染。与前鼻镜检查的阴性对照相比，单极电凝（ < 0.001）和经鼻刮除（ = 0.003）后总 0.300-10.000 μm 气溶胶增加。打开皮肤-软组织包膜、经鼻截骨和经皮截骨均未产生可检测到的气溶胶增加（ > 0.15）。在本研究中，紫外线下未观察到飞沫，只有电凝和经鼻刮除才会产生气溶胶。
