Summary
This study developed a semi-automatic algorithm for preoperative planning of endoscopic stapes surgery. The algorithm showed 70% accuracy in predicting scutum removal, aiding surgical feasibility assessment.
Area of Science:
- Otolaryngology
- Medical Imaging
- Surgical Simulation
Background:
- Endoscopic stapes surgery is a complex procedure.
- Accurate preoperative assessment is crucial for surgical success.
Purpose of the Study:
- To evaluate the accuracy of a semi-automatic algorithm for preoperative assessment of endoscopic stapes surgery.
- To determine the algorithm's ability to predict surgical feasibility and complexity.
Main Methods:
- A semi-automatic algorithm was developed for 3D simulation of endoscopic stapes surgery.
- CT scans of cadaveric heads were used for segmentation and 3D reconstruction.
- Algorithm-based planning was compared against actual surgical outcomes.
Main Results:
- The algorithm achieved 70% accuracy in predicting the need for scutum removal.
- Endoscopic surgery was feasible in all cases, with landmarks adequately visualized as predicted.
- Mean scutum removal volume was 0.5 mm³.
Conclusions:
- Preoperative planning models can aid ENT surgeons in assessing endoscopic stapes surgery.
- These models have the potential to improve predictive accuracy and patient outcomes.
