Summary
Computer-assisted surgery (CAS) enhances endoscopic sinus surgery by providing intraoperative localization. This system improves surgical field clarity, aiding diagnosis and minimally invasive treatment of nasal and sinus diseases.
Area of Science:
- Otolaryngology
- Medical Imaging
- Surgical Technology
Background:
- Endoscopic sinus surgery enables minimally invasive diagnosis and treatment of sinonasal diseases.
- Maintaining a clear surgical field during these procedures can be challenging.
- Computer-assisted surgery (CAS) systems offer intraoperative localization to address this limitation.
Purpose of the Study:
- To adapt and evaluate CAS for endoscopic sinus surgery.
- To explore various visualization techniques for integrating CAS with endoscopy.
- To determine the most effective display method for combined endoscopic and CAS navigation.
Main Methods:
- Adapted a CAS system, functioning as an intraoperative localizer, for endoscopic sinus surgery.
- Utilized preoperative CT scans for 3D reconstruction and superimposed endoscope positioning.
- Tested conventional endoscopes as localizing probes.
- Developed and assessed dual-display and single-display visualization techniques.
Main Results:
- CAS provides continuous orientation during endoscopic sinus surgery using preoperative CT data.
- A single-display technique, integrating both endoscopic video and CAS navigation on one monitor, emerged as the most promising visualization method.
- This approach effectively combines endoscopy with intraoperative CT-image-guided localization.
Conclusions:
- Computer-assisted surgery significantly improves orientation and surgical field clarity in endoscopic sinus procedures.
- The single-display visualization technique offers an effective solution for integrating navigation data with the endoscopic view.
- This technology enhances the precision and safety of minimally invasive sinonasal surgery.
