Abstract：
Owing to recent advances in medical optical technology, a high-definition (4K) three-dimensional (3D) exoscope has been developed as an alternative tool to using conventional microscopes for microscopic surgery, and its efficacy for neurosurgery has been reported. We report a case who underwent simultaneous surgery aiming for en bloc resection of an anterior skull base malignancy with concurrent exoscopic transcranial and endoscopic endonasal approaches using a 4K 3D exoscope. The patient was a 76-year-old woman who underwent en bloc resection for an anterior skull base olfactory neuroblastoma 13 years ago. After confirming the recurrence of progressive olfactory neuroblastoma, tumor resection was again decided to be performed. As with the first procedure, surgery was performed in an en bloc manner, using both transcranial and endonasal approaches. Exoscope provided enough space above the surgical field to allow us to perform transcranial and endonasal surgeries simultaneously. Moreover, the surgeons could maintain a comfortable posture throughout the procedure, and total tumor removal was successfully achieved without any abnormal event. To our knowledge, this is the first report of the introduction of an exoscope aiming for en bloc resection of an anterior skull base malignancy while performing simultaneous surgery with both transcranial and endonasal approaches. We believe that the more cases are accumulated, the more efficacy of a 4K 3D exoscope will be elucidated.
摘要：
由于医疗光学技术的最新进展，已开发出高清（4K）三维（3D）外镜，作为使用常规显微镜进行显微外科手术的替代工具，其对神经外科的疗效已有报道。我们报告了一例同时进行手术的病例，目的是同时进行手术，目的是使用4K3D外镜同时进行外镜经颅和内窥镜经鼻入路切除前颅底恶性肿瘤。该患者是一名76岁的女性，她在13年前接受了前颅底嗅神经母细胞瘤的整块切除术。在确认进行性嗅神经母细胞瘤复发后，再次决定进行肿瘤切除.和第一个程序一样，手术是以整体的方式进行的，使用经颅和鼻内入路。外镜在手术区域上方提供了足够的空间，使我们能够同时进行经颅和鼻内手术。此外，外科医生可以在整个手术过程中保持舒适的姿势，成功实现了肿瘤的全部切除，没有发生任何异常事件。据我们所知,这是首次报道引入的外镜，旨在对前颅底恶性肿瘤进行整块切除，同时进行经颅和鼻内手术。我们相信累积的病例越多,将阐明4K3D外镜的更多功效。
