Skull base surgery (including endoscopic approaches)

Skull base surgery is a highly specialized neurosurgical approach used to access and treat tumors, vascular lesions, and other conditions located at the base of the skull. These areas are often complex and surrounded by critical nerves and blood vessels, requiring precise surgical planning.

Endoscopic skull base surgery is a minimally invasive technique where surgeons use thin, flexible endoscopes through the nasal passages or small openings to reach lesions, reducing the need for large incisions. This approach can shorten recovery time, minimize surgical trauma, and improve cosmetic outcomes while maintaining the highest standards of safety and effectiveness.

Symptoms depend on the location and type of lesion, but may include:

  • Headaches
  • Vision or eye movement changes
  • Loss of smell or taste
  • Hearing loss or ringing in the ears
  • Facial numbness or weakness
  • Difficulty swallowing or speech changes

Comprehensive evaluation is required to plan safe and effective surgery:

  • MRI and CT scans to map the lesion and surrounding structures
  • Angiography for vascular lesions
  • Endoscopic assessment when minimally invasive access is considered
  • Detailed neurological and cranial nerve examinations

This ensures precise surgical planning and optimal outcomes.

Skull base surgery involves careful microsurgical or endoscopic approaches to remove tumors, repair vascular anomalies, or manage other complex lesions. Techniques may include:

  • Traditional open microsurgical approaches for complex lesions
  • Endoscopic endonasal approaches for minimally invasive access
  • Reconstruction of skull base defects when needed
  • Multidisciplinary collaboration with ENT, neurosurgery, and neuro-ophthalmology specialists

Recovery and follow-up depend on the lesion type and surgical approach but typically include imaging and clinical monitoring to ensure complete treatment and functional preservation.
