Comparison of six three-dimensional navigation systems during sinus surgery.

Area of Science:

• Neurosurgery
• Otolaryngology
• Medical Technology

Background:

• Three-dimensional (3D) navigation systems are integral to various surgical specialties, including skull base, neurosurgery, maxillo-facial, and endoscopic sinus surgery.
• These systems offer potential benefits such as improved 3D orientation, enhanced surgeon confidence, more precise surgical approaches, and reduced operation times.

Purpose of the Study:

• To compare the performance of six different brands of 3D navigation systems.
• To determine if significant performance differences justify the substantial financial investment in these systems.
• To assess the impact on surgical interventions and expected benefits.

Main Methods:

• A comparative study involving six brands of 3D navigation systems.
• Testing was conducted during endoscopic sinus surgery on 26 patients with chronic sinusitis.
• Key metrics evaluated included system accuracy, surgeon confidence, anesthesia duration, cost, personnel requirements, and technical resources.

Main Results:

• No major performance differences were observed among the six evaluated 3D navigation system brands.
• All systems demonstrated high, albeit variable, precision.
• Surgeons reported increased confidence, but anesthesia time was prolonged by 5-15 minutes.
• A well-trained operating staff is essential for effective use.

Conclusions:

• The study found no substantial performance disparities between the evaluated 3D navigation system brands for endoscopic sinus surgery.
• While surgeon confidence may increase, the prolonged anesthesia time and need for skilled personnel are important considerations.
• The financial justification for purchasing these systems requires careful evaluation beyond initial cost, including ongoing personnel and time expenses.
