Summary
Serious complications in endonasal sinus surgery are highest in early stages, decreasing with experience. Direct supervision is crucial for beginners, while experienced surgeons need self-criticism to minimize risks.
Area of Science:
- Otolaryngology
- Surgical Safety
- Medical Education
Background:
- Optical aids in endonasal sinus surgery have not reduced serious intraoperative complication rates as anticipated.
- Understanding the learning curve is vital for improving surgical outcomes and patient safety.
Purpose of the Study:
- To analyze the learning curve for endonasal sinus surgery and identify critical stages for complication risk.
- To evaluate the effectiveness of different support systems for surgeons at various experience levels.
Main Methods:
- Retrospective analysis of 1,500 endonasal sinus surgeries performed by five surgeons, focusing on major intraoperative complications.
- Development of a learning curve based on chronological complication data, categorized into three stages.
- Comparison of experienced surgeons' complication rates with the established learning curve.
Main Results:
- A total of 16 serious complications were recorded across the analyzed surgeries.
- Stage I (1-30 operations) showed the highest risk, particularly dural injuries.
- Stage II (31-180 operations) had a reduced risk with more frequent periorbital injuries. Stage III represented experienced surgeons with the lowest risk, yet surprisingly, serious complications were most frequent in this group.
Conclusions:
- Beginner surgeons benefit most from direct, constant supervision by an experienced surgeon during the initial 30 operations, with availability for the next 70.
- While multimedia software may offer assistance, its definitive value requires further determination.
- Experienced surgeons must maintain rigorous self-criticism to minimize their complication rates.
