To investigate the importance of anatomical variation in acquiring skills in virtual reality cochlear implant surgery.
Eleven otolaryngology residents participated in this study. They were randomly allocated to practice cochlear implant surgery on the same specimen or on different specimens for four weeks. They were then tested on two new specimens, one standard and one challenging. Videos of their performance were de-identified and reviewed independently, by two blinded consultant otolaryngologists, using a validated assessment scale. The scores were compared between groups.
On the standard specimen, the round window preparation score was 2.7 ± 0.4 for the experimental group and 1.7 ± 0.6 for the control group (p = 0.01). On the challenging specimen, instrument handling and facial nerve preservation scores of the experimental group were 3.0 ± 0.4 and 3.5 ± 0.7 respectively, while the control group received scores of 2.1 ± 0.8 and 2.4 ± 0.9 respectively (p < 0.05).
Training on temporal bones with differing anatomies is beneficial in the development of expertise.
探讨解剖变异在虚拟现实人工耳蜗植入手术技能获取中的重要性。
11名耳鼻喉科住院医师参与了本研究。他们被随机分配在四周内对同一标本或不同标本进行人工耳蜗植入手术练习。然后，他们在两个新标本上接受测试，一个是标准标本，一个是具有挑战性的标本。他们手术表现的视频经过去识别处理后，由两名不知情的耳鼻喉科顾问医生使用经过验证的评估量表进行独立审查。对两组的分数进行比较。
在标准标本上，实验组的圆窗制备分数为2.7±0.4，对照组为1.7±0.6（p = 0.01）。在具有挑战性的标本上，实验组的器械操作和面神经保留分数分别为3.0±0.4和3.5±0.7，而对照组的分数分别为2.1±0.8和2.4±0.9（p < 0.05）。
