Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Background:

  • Image-guided surgery (IGS) enhances precision in otological procedures.
  • Accurate patient-to-image registration is crucial for IGS effectiveness.
  • The registration centroid's accuracy significantly impacts surgical outcomes.

Purpose of the Study:

  • To develop an optimized registration procedure for enhanced accuracy in image-guided otological surgery.
  • To investigate the impact of registration centroid weighting on accuracy.
  • To determine the optimal distribution of fiducial points for improved registration.

Main Methods:

  • A head phantom was utilized to measure target registration error (TRE).
  • Surface-matching registration was performed using a commercial surgical navigation system.
  • Registration was tested using symmetrical and asymmetrical weighting ratios (0:100, 25:75, 50:50, 75:25) of bilateral ear data.

Main Results:

  • Overall TRE was minimized with equal weighting (50:50) of bilateral data.
  • TRE at depths of 20-50 mm was significantly reduced with asymmetrical weighting (75:25), favoring the operating side.
  • Asymmetrical weighting demonstrated statistically significant improvements in registration accuracy at specific depths.

Conclusions:

  • Surgical navigation accuracy in otological procedures can be enhanced through strategic planning of the registration process.
  • A registration ratio of 75% from the operating side and 25% from the contralateral side yields accurate image-guided surgery in the middle and inner ear.
  • Careful consideration of registration point distribution optimizes IGS accuracy without altering the core procedure.
