Nasal airway obstruction (NAO) is a common problem that affects patient quality of life. Surgical success for NAO correction is variable. Virtual surgery planning via computational fluid dynamics (CFD) has the potential to improve the success rates of NAO surgery.
To elicit surgeon feedback of a virtual surgery planning tool for NAO and to determine if this tool affects surgeon decision making.
DESIGN, SETTING, AND PARTICIPANTS: For this cross-sectional study, 60-minute face-to-face interviews with board-certified otolaryngologists were conducted at a single academic otolaryngology department from September 16, 2016, through October 7, 2016. Virtual surgery methods were introduced, and surgeons were able to interact with the virtual surgery planning tool interface. Surgeons were provided with a patient case of NAO, and open feedback of the platform was obtained, with emphasis on surgical decision making.
Likert scale responses and qualitative feedback were collected for the virtual surgery planning tool and its influence on surgeon decision making.
Our 9 study participants were all male, board-certified otolaryngologists with a mean (range) 15 (4-28) number of years in practice and a mean (range) number of nasal surgeries per month at 2.2 (0.0-6.0). When examined on a scale of 1 (not at all) to 5 (completely), surgeon mean (SD) score was 3.4 (0.5) for how realistic the virtual models were compared with actual surgery. On the same scale, when asked how much the virtual surgery planning tool changed surgeon decision making, mean (SD) score was 2.6 (1.6). On a scale of 1 (strongly disagree) to 7 (strongly agree), surgeon scores for perceived usefulness of the technology and attitude toward using it were 5.1 (1.1) and 5.7 (0.9), respectively.
Our study shows positive surgeon experience with a virtual surgery planning tool for NAO based on CFD simulations. Surgeons felt that future applications and areas of study of the virtual surgery planning tool include its potential role for patient counseling, selecting appropriate surgical candidates, and identifying which anatomical structures should be targeted for surgical correction.

鼻气道阻塞（NAO）是一种常见的问题，影响患者的生活质量。NAO 矫正手术的成功率存在差异。通过计算流体动力学（CFD）进行虚拟手术规划有可能提高 NAO 手术的成功率。
征求外科医生对 NAO 虚拟手术规划工具的反馈意见，并确定该工具是否会影响外科医生的决策。
设计、地点和参与者：这是一项横断面研究，于 2016 年 9 月 16 日至 10 月 7 日在一家学术耳鼻喉科部门进行了 60 分钟的面对面访谈，受访者为 60 名已通过董事会认证的耳鼻喉科医生。介绍了虚拟手术方法，外科医生可以与虚拟手术规划工具界面进行交互。为外科医生提供了一个 NAO 患者的病例，并获得了平台的开放式反馈，重点是手术决策。
对虚拟手术规划工具及其对外科医生决策的影响收集了李克特量表的反应和定性反馈。
我们的 9 名研究参与者均为男性，均为已通过董事会认证的耳鼻喉科医生，平均（范围）从业年限为 15 年（4-28 年），平均（范围）每月进行鼻手术次数为 2.2 次（0.0-6.0 次）。在 1（完全不）到 5（完全）的量表上，外科医生对虚拟模型与实际手术的逼真程度的平均（标准差）评分是 3.4（0.5）。在同一量表上，当被问及虚拟手术规划工具在多大程度上改变了外科医生的决策时，平均（标准差）评分是 2.6（1.6）。在 1（强烈不同意）到 7（强烈同意）的量表上，外科医生对该技术的实用性和使用态度的评分分别为 5.1（1.1）和 5.7（0.9）。
我们的研究表明，基于 CFD 模拟的 NAO 虚拟手术规划工具得到了外科医生的积极反馈。外科医生认为，该虚拟手术规划工具的未来应用和研究领域包括它在患者咨询、选择合适的手术候选者以及确定应针对哪些解剖结构进行手术矫正方面的潜在作用。
