Area of Science:

  • Biomedical Engineering
  • Plastic Surgery
  • Regenerative Medicine

Background:

  • Three-dimensional (3D) digital imaging and printing are increasingly used in microtia reconstruction.
  • Clinical reports on using 3D printed ear subunit models for cartilage framework fabrication are limited.

Purpose of the Study:

  • To evaluate the clinical application of 3D printed ear subunit models for cartilage framework fabrication in microtia reconstruction.
  • To assess the accuracy and aesthetic outcomes of auricle reconstruction using these models.

Main Methods:

  • Retrospective study of patients undergoing auricle reconstruction with 3D templates.
  • Analysis of patient demographics, surgical complications, framework accuracy, and aesthetic outcomes.

Main Results:

  • Twenty cases were included in the study.
  • Complications were minor, with high average scores for framework quality (8.50) and reconstructed auricle aesthetics (8.30).

Conclusions:

  • Custom-printed three-dimensional ear subunit models achieve high framework precision in microtia reconstruction.
  • This technique yields favorable aesthetic outcomes for reconstructed ears.
