耳蜗植入术是一种用于治疗听力损失患者的外科手术，其中将电极阵列插入耳蜗中。传统的手术方法需要钻掉耳后的大部分骨头，以提供解剖学参考和进入耳蜗。一种称为经皮耳蜗植入术（PCI）的微创技术已经提出，该技术涉及从侧颅骨到耳蜗钻一条线性路径，避开重要结构，并使用钻好的路径插入植入物。安全实现PCI所需的步骤包括：在耳朵周围放置三个骨植入标记物，获得CT扫描，规划耳蜗的手术路径，避免重要解剖结构，设计并制作了一个微立体定向框架，该框架安装在标记物上并将钻头限制在计划的路径上，将框架固定在标记物上，使用该框架钻到耳蜗中，并通过钻好的路径插入电极。为每个标本制作一个定制的固定装置，称为Microtable，这是一种可以在不到五分钟内构建的微立体定向框架，用于到达耳蜗。在所有三个样本上成功进行了插入。插入后CT扫描确认耳蜗内电极的正确放置，而不会对面神经造成任何损伤。
Cochlear implantation is a surgical procedure for treating patients with hearing loss in which an electrode array is inserted into the cochlea. The traditional surgical approach requires drilling away a large portion of the bone behind the ear to provide anatomical reference and access to the cochlea. A minimally-invasive technique, called percutaneous cochlear implantation (PCI), has been proposed that involves drilling a linear path from the lateral skull to the cochlea avoiding vital structures and inserting the implant using that drilled path. The steps required to achieve PCI safely include: placing three bone-implanted markers surrounding the ear, obtaining a CT scan, planning a surgical path to the cochlea avoiding vital anatomy, designing and constructing a microstereotactic frame that mounts on the markers and constrains the drill to the planned path, affixing the frame on the markers, using it to drill to the cochlea, and inserting the electrode through the drilled path. We present in this paper a cadaveric study demonstrating the PCI technique on three temporal bone cadaveric specimens for inserting electrode array into the cochlea. A custom fixture, called a Microtable, which is a type of microstereotactic frame that can be constructed in less than five minutes, was fabricated for each specimen and used to reach the cochlea. The insertion was successfully performed on all three specimens. Postinsertion CT scans confirm the correct placement of the electrodes inside the cochlea without any damage to the facial nerve.
