Summary
Computer-aided surgery (CAS) is safe and effective for endoscopic endonasal surgery. This system provides sufficient accuracy for both primary and revision procedures, enhancing patient outcomes.
Area of Science:
- Otolaryngology
- Medical technology
- Surgical navigation
Background:
- Computer-aided surgery (CAS) is increasingly adopted in Ear, Nose, and Throat (ENT) surgery.
- Endoscopic endonasal approaches benefit significantly from advanced surgical navigation.
Purpose of the Study:
- Evaluate the practical utility of a frameless CAS system (SurgiGATE ORL TM) for endoscopic endonasal surgery.
- Assess system setup time, referencing accuracy, and clinical precision.
Main Methods:
- Thirty-two patients underwent endoscopic endonasal surgery utilizing CAS.
- Included 13 revision and 19 primary cases involving sinonasal diseases and tumors.
- Paired points matching was used for referencing, with accuracy measured against CT scan pixel size.
Main Results:
- Mean referencing attempts were 1.8; mean supplementary setup time was 15 minutes.
- Clinical accuracy ranged from 0.5 mm to 2 mm at two confidence points.
- No major complications occurred; one minor tongue edema case was reported due to reference base placement.
Conclusions:
- CAS with optonavigation (SurgiGATE ORL TM) is a safe and efficient tool for endoscopic endonasal procedures.
- The system demonstrates adequate accuracy for both primary and revision rhinologic surgeries.
- Its application is deemed appropriate for enhancing surgical precision in this field.
