Area of Science:

  • Neurosurgery
  • Medical Technology
  • Image-Guided Therapy

Background:

  • Minimally invasive resection in the central sensorimotor strip is challenging due to the critical function of this brain region.
  • Conventional stereotaxy may have limitations in guiding surgical access to small, deep-seated lesions.

Purpose of the Study:

  • To demonstrate the efficacy of a novel optical navigation device in microsurgical procedures.
  • To assess the feasibility of less invasive resection for subcortical lesions in the sensorimotor strip.

Main Methods:

  • Six microsurgical procedures were performed using a new optical navigation system guided by high-resolution CT imaging.
  • The system utilized light-weight, freehand pointing instruments with +/- 1 mm accuracy for precise lesion localization and removal.

  • Surgical access involved oblique, transsulcal approaches to minimize damage to surrounding brain tissue and vessels.

    • Main Results:

    • Five brain tumors and one cavernous angioma were successfully located and resected with minimal invasiveness.
    • No additional sensorimotor deficits were observed post-surgery.
    • Two patients experienced immediate improvement in pre-operative paresis.
    • Cortical stimulation in three cases identified infiltrating tumors, enabling maximal resection.

    Conclusions:

    • Computer-aided surgery (CAS) with optical navigation provides precise anatomical localization for small central lesions, facilitating minimally invasive neurosurgery.
    • The demonstrated optical navigation system shows significant potential for improving surgical precision, quality control, and training in neurosurgery.
