This study introduces e-A.L.Ex, a 3D printed model for endoscopic adenoidectomy training. It enhances surgical education by simulating realistic anatomical structures and tissue for improved learning outcomes.

Area of Science:

  • Otolaryngology
  • Medical Education
  • 3D Printing Technology

Background:

  • Adenoidectomy is a common otolaryngology procedure.
  • Endoscopic techniques have advanced adenoidectomy, requiring specialized training.
  • Existing training methods may not fully replicate the complexities of endoscopic adenoidectomy.

Purpose of the Study:

  • To develop and evaluate a novel 3D printing model for endoscopic adenoidectomy training.
  • To create a realistic simulation tool for surgical trainees.
  • To improve the learning curve and outcomes of endoscopic adenoidectomy.

Main Methods:

  • Utilized computed tomography scans to create a 3D model.
  • Employed 3D printing technology for anatomical replication.
