Reduce Revisions with Image-Guided Surgery

Whether you're performing functional endoscopic sinus surgery (FESS) or operating in the skull base, meta-analyses on commercial image-guided navigation systems, like StealthStation™ ENT system, suggest a reduction in major complications during endoscopic sinus surgery compared with non-image guided procedures.1-3

Image-Guided Surgery and FESS

Image-guided surgery has become an industry standard for many endoscopic sinus surgeries. The American Academy of Otolaryngology – Head and Neck Surgery (AAO-HNS) endorses the use of image-guided surgery for procedures including4:

  • Revision sinus surgery
  • Distorted sinus anatomy of development, postoperative, or traumatic origin
  • Extensive sino-nasal polyposis
  • Pathology involving the frontal, posterior ethmoid and sphenoid sinuses
  • Disease abutting the skull base, orbit, optic nerve, or carotid artery
  • Cerebrospinal fluid rhinorrhea or conditions where there is a skull base defect
  • Benign and malignant sino-nasal neoplasms 

Additional Products for FESS

Medtronic offers powered and manual instruments that are specially designed for a broad variety of FESS procedures. Learn more about our additional products for FESS and their potential benefits for you and your patients.

Image-Guided Surgery in the Skull Base

Image-Guided Surgery in the Skull Base

Image-guided surgery with the StealthStation™ ENT Navigation System can be used to surgically navigate tumors and lesions affecting the anterior and lateral skull base. This is accomplished through:

  • Scanning and registration protocols that enable accuracy
  • StealthMerge™ ENT software that fuses different imaging modalities (CT, MRI) together for improved visualization
  • Instruments that are designed and calibrated for use in image-guided surgery

Benefits of image-guided surgery for ENT procedures

Benefits of image-guided navigated surgery include improvements in visualization, enabling surgeons to work within complex sinus anatomy and optimize surgical strategies for their patients.5-9

Patient benefits include:

  • Image-guided navigation systems used in endoscopic sinus surgery have shown a reduction in the need for revision surgeries.1-3
  • Meta-analyses on commercial image-guided navigation systems suggest a reduction in major complications during endoscopic sinus surgery compared with non-image guided procedures.10-13
