Intraoperative Micro-Measurement in Neurosurgical Microsurgery: A Technical Note

Area of Science:

• Neurosurgery
• Medical Imaging
• Microsurgical Techniques

Background:

• Accurate measurement of microstructures is critical for safe and minimally invasive neurosurgical microsurgery.
• Existing methods may lack precision for sub-millimeter structures.

Purpose of the Study:

• To introduce a simple digital method for measuring microvessel size using a computer-generated microscale.
• To validate the accuracy of this digital microscale for intracranial microstructures.

Main Methods:

• A digital image was converted into a functional microscale on a computer.
• The size of intracranial microstructures was measured using this digital microscale.

Main Results:

• The digital microscale accurately measured the size of the vertebral artery perforator.
• Measurements were precise for structures 1 mm or less.

Conclusions:

• A digital microscale is easily developed and provides accurate measurements of microstructures.
• This method enhances the feasibility of precise measurements for critical neurosurgical targets.
