"Open" transcortical and transcallosal approaches allow gross total colloid cyst resection but require a wider surgical corridor through normal brain tissue compared with endoscopic techniques. Although the use of tubular retractor systems has been previously reported, the minimum required diameter size for the retractor tube has been approximately 16 to 22 mm. Our objective was to explore the use of smaller retractor tubes for total resection of colloid cysts.
A minitubular retractor with a 12-mm diameter was used to access and resect colloid cysts using microsurgical techniques while preserving stereoscopic vision as an alternative to open and endoscopic surgical routes.
This technique was adopted in five patients with larger than 10-mm colloid cysts to allow for gross total resection of the cysts in every case without any complication.
Smaller retractor tubes may be used for resection of colloid cysts while minimizing brain retraction injury and potentially improving outcomes.
“开放式”经皮质和胼胝体入路允许对胶体囊肿进行大体全切除，但与内镜技术相比，需要通过正常脑组织的更宽的手术通道。虽然以前已经报道了使用管状牵开器系统，但牵开器管的最小所需直径约为 16 至 22 毫米。我们的目的是探索使用更小的牵开器管进行胶体囊肿的全切除。
使用直径为 12 毫米的微型管状牵开器，采用显微外科技术，在保留立体视觉的情况下，通过经颅途径进入并切除胶体囊肿，作为开放式和内镜手术途径的替代方法。
该技术在五例直径大于 10 毫米的胶体囊肿患者中得到采用，使所有病例均能进行大体全切除囊肿，且无任何并发症。
在最小化脑牵拉损伤的同时，使用更小的牵开器管可能有助于切除胶体囊肿，从而可能改善患者预后。
