    Real-time surgical navigation technology aids cranial base and paranasal sinus surgeries. This frameless stereotactic platform improved accuracy and safety, reducing complications and enhancing patient outcomes in 88 cases.

    Area of Science:

    • Neurosurgery
    • Otolaryngology
    • Medical Imaging

    Background:

    • Accurate three-dimensional understanding of cranial base/paranasal sinus anatomy is crucial for surgical success.
    • Minimizing iatrogenic complications, ensuring complete tumor removal, and optimizing functional results are key surgical goals.
    • Real-time intraoperative localization technology offers a potential solution to enhance surgical precision.

    Purpose of the Study:

    • To report institutional experience with the StealthStation treatment guidance platform for cranial base/paranasal sinus surgery.
    • To evaluate the accuracy, applications, and impact of real-time frameless stereotactic localization in these complex procedures.

    Main Methods:

    • Eighty-eight consecutive patients underwent cranial base/paranasal sinus surgery using real-time frameless stereotactic localization.

  • Preoperative imaging utilized either CT or MRI scans.
  • Data collected included patient demographics, imaging accuracy, surgical approaches, pathology, and complications.

    • Main Results:

    • Procedures were performed on 88 patients (47 female, 41 male; age 6-85).
    • Accuracy of CT and MRI datasets averaged 1.23 mm and 1.57 mm, respectively.
    • Complications occurred in 10 out of 88 patients (11.4%).

    Conclusions:

    • Real-time intraoperative localization is applicable to diverse cranial base surgical scenarios.
    • The technology facilitates pathology localization, enhances operative safety, and reduces morbidity.
    • This navigation system plays an integral role in minimizing complications and improving surgical outcomes.
