Markerless registration using the auricle can simplify computer-assisted lateral skull base surgery. However, auricular deformation during CT scanning can impact accuracy, necessitating modifications to head supports for consistent results.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Background:

  • Markerless registration methods can streamline logistics for computer-assisted lateral skull base surgery.
  • Previous markerless methods primarily utilized the facial skin surface, excluding areas near the lateral skull base.

Purpose of the Study:

  • To evaluate the auricle as an accurate spatial reference for markerless patient registration in image-guided lateral skull base surgery.

Main Methods:

  • A prospective clinical study involving ten patients undergoing image-guided surgery for cranial pathologies.
  • Markerless patient registration was performed using laser-scanning with the SSN++ navigation system.
  • Periauricular and oral evaluation markers were used to assess registration precision.

Main Results:

  • High accuracy (mean target detection error of 0.9 mm ± 0.3 mm) was achieved using the auricle for markerless registration.
  • Temporary auricular deformations caused by conventional CT head supports in 50% of patients led to impossible laser-scan registration.
  • Accuracy was maintained when the auricle was not deformed during CT imaging or laser scanning.

Conclusions:

  • Automated laser registration of the auricle reduces logistical requirements for computer-assisted lateral skull base surgery.
  • Accuracy comparable to marker-based methods can be achieved with markerless auricular registration.
  • Modifications to CT head supports, including an opening at the auricular level, are crucial to prevent deformations and ensure consistent, accurate results.
