A simple paper model of the auricle (outer ear) can simulate auricular reconstruction. This model highlights the large skin area needed for the helical crus and offers new reconstructive possibilities.

Area of Science:

  • Anatomy
  • Biomedical Engineering
  • Developmental Biology

Background:

  • The auricle (outer ear) presents complex anatomical features.
  • Auricular reconstruction is a challenging surgical procedure.
  • Existing models may not fully capture the auricle's intricate structure.

Purpose of the Study:

  • To develop a simple, fabricated paper model of the human auricle.
  • To assess the model's utility in simulating auricular reconstruction.
  • To explore new reconstructive possibilities and understand developmental compatibility.

Main Methods:

  • Designing a paper model by folding an oval sheet.
  • Centering prominent and hollow parts around the helical crus and concha.
  • Analyzing the model's representation of auricle anatomy.

Main Results:

  • The paper model successfully replicates most parts of the human auricle.
  • A significant skin area requirement for the helical crus was identified.
  • The model's formation process mirrors embryonic auricle development.

Conclusions:

  • The paper model is a valuable tool for simulating auricular reconstruction.
  • It suggests novel reconstructive approaches using flat, large tissue grafts.
  • The model's formation mechanism offers insights into embryonic auricle development.
