摘要

Objective

This study introduces a hybrid training model for endolaryngeal surgeries integrating a porcine larynx into a plastic airway manikin. The study explores interventions with a conventional rigid laryngoscope as well as with the novel hyperangulated laryngoscope for surgery (sMAC).

Methods

We integrated a porcine larynx into a plastic airway manikin with blue markings on vocal folds simulating lesions and utilized a conventional rigid laryngoscope and the sMAC for endolaryngeal cordectomies and biopsies.

Results

The setup provided clear visual exposure of the glottic plane, enabling precise surgical interventions. Trained surgeons and residents successfully performed cordectomies and biopsies on the model.

Conclusion

The hybrid model offers a realistic, cost-effective solution for training and testing endolaryngeal surgical procedures, particularly with the sMAC. Despite anatomical differences between porcine and human larynges, the model’s affordability and tissue similarity render it a valuable training tool. Further studies are warranted to evaluate its efficacy for training.
