OBJECT: An endoscopic surgical technique utilizing a rollable @entity3324 tube as a surgical corridor is described for removal of third @entity2504 . SURGICAL TECHNIQUE: Transcortical transventricular access is made via a burr hole placed at the point which is one inch lateral from the midline at the coronal suture area. A one-cm-diameter @entity3324 tube is slit longitudinally, rolled like a cigarette, and tied at its ventricular end with a release tie. With image-guided stereotactic assistance, this rolled @entity3324 tube is inserted into the lateral ventricle near the foramen of Monro. When the release tie is untied, the @entity3324 tube expands to its original 10-mm-diameter tube by recoil assisted with a @entity384 technique. Through this tube, a rod-lens endoscope is placed to visualize the surgical target and is mounted to an endoscope holder. Surgical instruments are inserted next to the endoscope for surgical dissection. Compared to endoscopy through fixed working-channel devices, this technique allows increased flexibility for the surgeon when maneuvering surgical instruments for delicate dissection and @entity5 removal. Two @entity1 with @entity2776 and one @entity1 with an epidermoid @entity5 are reported as demonstrative cases. CONCLUSION: An endoscopic technique utilizing a soft @entity3324 tube which can be rolled into a small diameter and then unrolled to its original size by its own recoil when a release tie is removed and by @entity384 , is reported for removal of third @entity2504 .
