Summary
This study evaluated the SPOCS Aesculap navigation system for sinus surgery. The system provided constant orientation and identified critical structures, achieving 1-3 mm precision, but increased operation time.
Area of Science:
- Otorhinolaryngology
- Medical Technology
- Surgical Navigation
Background:
- Chronic sinus pathology often requires surgical intervention.
- Intraoperative navigation systems aim to improve surgical accuracy and safety.
- Computed tomography (CT) provides detailed anatomical information for surgical planning.
Purpose of the Study:
- To evaluate the precision and accuracy of the Surgical Planning and Orientation Computer Systems (SPOCS) Aesculap navigation system in sinus surgery.
- To assess the system's utility as a technical aid in ENT sinus surgery.
Main Methods:
- Five patients with chronic sinus pathology undergoing surgery were included.
- The SPOCS Aesculap navigation system with light-emitting diode-fitted instruments was used for intraoperative guidance.
- System precision was measured by landmark identification, and accuracy was assessed using CT scan data and root mean square error.
Main Results:
- The SPOCS Aesculap system demonstrated a precision between 1 and 3 mm.
- The system provided constant intraoperative orientation, aiding in the identification of critical anatomical structures.
- Data transfer via optical disk was practicable, and axial spiral CT offered sufficient resolution.
Conclusions:
- The SPOCS Aesculap computed navigation system is a viable technical aid for ENT sinus surgery.
- The system enhances surgical orientation and decision-making by providing real-time anatomical reference.
- While effective, the navigation system increased operative time by approximately one hour.
