Bony surface registration of navigation system in the lateral or prone position: technical note

Abstract

This is the first report of a registration methodology for a navigation system in the lateral or prone position. This bony surface registration method is useful for navigation system image-guided surgery in the lateral or prone position.

Neuroendoscopy via an Extremely Narrow Foramen of Monro: A Case Report

“…After dural incision and arachnoid coagulation, the lateral ventricle was approached, with ventricular tap needle, under navigational guidance ( BrainLAB, Feldkirchen, Germany ). 4) Only the location of the entry point and the approach trajectory were determined with neuronavigation while the procedure itself was performed under endoscopic visual control. Once the ventricle was cannulated, CSF pressure was measured and samples were sent for further analysis.…”

Real-Time Navigation-Guided Drilling Technique for Skull Base Surgery in the Middle and Posterior Fossae

“…It is an essential technology for skull base surgery in which the operative field is deep and narrow, and has several critical structures, including vessels, and nerves. [1][2][3][4] Facial surface matching registration is difficult in the middle or posterior fossa skull base surgery with the patient in the lateral or prone position because of the direction of the face, skin shifting, and adhesive facial monitoring tape. This represents a very serious problem because accurate registration is essential for precise navigation.…”

“…This represents a very serious problem because accurate registration is essential for precise navigation. 2,3 Therefore, navigation systems are not commonly applied in the middle or posterior fossa skull base surgery with the patient in the lateral or prone position. 1,3 To resolve this problem and facilitate application of navigation systems to skull base surgery in the lateral or prone position, we developed a new bony surface registration method that enables highly precise navigation in the middle and posterior fossa skull base surgery.…”

However, no standardized intraoperative techniques have been developed to protect the labyrinth.…”
