Summary
Computer-assisted surgery (CAS) significantly improves surgical accuracy for inexperienced surgeons performing endoscopic sinus surgery (ESS). This technology reduces the risk of complications and may enhance the learning curve for residents.
Area of Science:
- Otolaryngology
- Surgical Technology
- Medical Education
Background:
- Endoscopic sinus surgery (ESS) requires precise anatomical knowledge.
- Inexperienced surgeons face challenges in identifying critical structures during ESS.
Purpose of the Study:
- To evaluate the efficacy of computed tomographic image-guided computer-assisted surgery (CAS) for novice surgeons performing ESS.
- To assess the impact of CAS on surgical accuracy, operative time, and complication rates.
Main Methods:
- Four otolaryngology residents with no prior ESS experience performed procedures on cadaveric specimens.
- Surgical accuracy, operative time, and complications were compared between procedures with and without CAS.
- Pearson's chi2 analysis was used for statistical comparison.
Main Results:
- CAS group demonstrated significantly higher accuracy (97%) in identifying anatomical landmarks compared to the non-CAS group (76.8%).
- Three major intracranial complications occurred exclusively in the non-CAS group.
- Operative time was slightly longer with CAS, but accuracy was markedly improved.
Conclusions:
- Computer-assisted surgery (CAS) enhances surgical accuracy and reduces the risk of major complications in ESS for residents.
- CAS may improve the learning curve by maintaining high accuracy, potentially reducing operative time.
- A strong understanding of anatomy remains crucial, but CAS serves as a valuable adjunct for surgical training.
