Summary

Three-dimensional (3D) printed nasal models significantly improve residents' ability to correlate external and internal nasal anatomy. These models are highly rated for educational use in rhinoplasty training.

Area of Science:

  • Medical Education
  • Surgical Anatomy
  • 3D Printing Technology

Background:

  • Learning rhinoplasty presents challenges in correlating external and internal nasal structures.
  • Accurate identification of nasal anatomy is crucial for successful rhinoplasty outcomes.

Purpose of the Study:

  • To explore the application of three-dimensional (3D)-printed models of nasal bony-cartilaginous structures.
  • To assess the utility of 3D models in improving the understanding of accurate nasal anatomy for surgical trainees.

Main Methods:

  • Otolaryngology-head and neck surgery and plastic and reconstructive surgery residents participated in the study.
  • Participants matched patient photograph models with 3D-printed nasal anatomy models.
  • Pre- and post-activity self-evaluations were completed, focusing on nasal deformity milestones.

Main Results:

  • Residents demonstrated moderate accuracy in matching models and describing nasal anatomy.
  • A statistically significant correlation was found between postgraduate year and performance.
  • Learners rated the 3D models as highly useful (median 85/100) with strong recommendation for future use (median 87/100).

Conclusions:

  • Three-dimensional printed models are valuable tools for enhancing the understanding of nasal anatomy in surgical education.
  • Further standardization of 3D model designs and educational assessments are recommended for wider implementation.
