Summary

Image-guided surgical navigation (IGSN) in complex otologic surgery demonstrated high accuracy, potentially improving outcomes and reducing complications. While IGSN is valuable, it complements, not replaces, surgeon expertise.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Medical Imaging

Background:

  • Complex otologic surgeries present significant anatomical challenges.
  • Accurate navigation is crucial for optimal patient outcomes and minimizing morbidity.

Purpose of the Study:

  • To evaluate the efficacy of image-guided surgical navigation (IGSN) in otologic surgery.
  • To establish practice guidelines for IGSN in complex otologic procedures.

Main Methods:

  • Prospective study involving patients undergoing complex otologic surgery.
  • IGSN was offered to patients with chronic otitis media, glomus jugulare, atresia, CSF leak, and petrous apex cholesterol granuloma.
  • Accuracy, operative time, complications, and surgical outcomes were recorded for IGSN procedures.

Main Results:

  • IGSN was utilized in 15 procedures across 13 patients.
  • The mean accuracy error was within 1 mm for 10 of 11 targeted anatomic landmarks.
  • Average additional operative time was 36.7 minutes, with a minimum 6-month follow-up.

Conclusions:

  • IGSN may enhance surgical outcomes and decrease morbidity in complex otologic surgery.
  • Real-time instrument display aids in distinguishing distorted anatomy, potentially justifying costs.
  • IGSN is a valuable tool but does not substitute surgical expertise.
