Exploration in neuroendoscopic surgery is occasionally insufficient because of the
structural limitations in endoscope. It is not easy to identify the precise position
of the endoscope during an operation. We here show a coaxial technique for neuroendoscopic
exploration with monitoring by means of a microfiberscope. The endoscopic coaxial
technique consists of two scopes. The microfiberscope has a diameter of 0.75 mm, flexible
body and high-quality image system. We tested its ability to visualize the subject
at several distances and applied this coaxial technique in neuroendoscopic surgery.
The microfiberscope not only visualizes the object but also magnifies it by a distance.
The scope was easy to handle with monitoring of its movement in the endoscopic view.
The technique allowed us to safely explore details which are difficult to approach
with an ordinary fiberscope or rigid-rod scope. The microfiberscope also adjusts to
the neuronal anatomy and many clinical situations. Taken together, the microfiber
coaxial technique might offer new advantages to modern neuroendoscopic surgery.
