Abstract：
Recent studies highlighted how exoscopes may be employed to approach the lateral skull base. The use of exoscope-assisted procedures to repair middle cranial fossa (MCF) defects has not been fully explored. The surgical microscope in the same circumstances has been associated with relevant limitations, such as its physical obstruction, among others. The aim of this study was to present a proof of concept of exoscope-assisted surgery for MCF defects.
A detailed step-by-step MCF approach was performed on 2 alcohol-preserved, latex-injected cadaveric specimens under exoscopic magnification. An illustrative clinical case of encephalocele secondary to a spontaneous tegmen tympani defect repaired via an exoscope-assisted MCF approach was presented.
The most common sites of MCF defects, the tegmen tympani and the arcuate eminence, were successfully exposed under exoscopic magnification. Dissection was easily performed; no damage to the dura mater or to vascular or neural structures occurred. In the clinical case, the exoscope-assisted technique demonstrated adequate maneuverability and magnification quality. After localization, the encephalocele was resected, and the MCF defect was repaired. The surgeon\'s position was comfortable, and operative time was not prolonged.
The exoscope allows adequate exposure of the MCF floor with identification and preservation of key anatomical structures. The exoscope represents a valuable alternative to the microscope in reconstruction of MCF defects, offering high-quality magnification and proven maneuverability.

摘要：
背景：最近的研究强调了如何使用外镜来接近侧颅底。尚未充分探索使用镜辅助手术修复中颅窝（MCF）缺损的方法。手术显微镜在相同的情况下也有相关的局限性，比如它的物理障碍，在其他人中。这项研究的目的是提供一个证明的概念，用于MCF缺损的外镜检查辅助手术。
方法：对2醇保存的MCF进行了详细的逐步MCF方法，乳胶注射的尸体标本在镜下放大。介绍了通过外镜检查辅助的MCF方法修复的自发性鼓膜缺损继发脑膨出的说明性临床病例。
结果：MCF缺陷最常见的部位，泰格曼鼓室和弓形突出，在镜下成功曝光。解剖很容易进行；没有对硬脑膜或血管或神经结构造成损害。在临床上，出镜辅助技术显示出足够的可操作性和放大质量。本地化后,切除了脑膨出,并修复了MCF缺陷。外科医生的位置很舒服，手术时间没有延长。
结论：出镜允许充分暴露MCF地板，识别和保留关键解剖结构。在MCF缺陷的重建中，外镜代表了显微镜的有价值的替代品，提供高质量的放大和证明的可操作性。
