Use of a plastic eraser for ear reconstruction training.

BACKGROUND

Microtia reconstruction is a challenging procedure, especially in developing nations. The most complex part is learning how to fabricate a framework from costal cartilage. We herein propose a training regimen for ear reconstruction with the use of a plastic eraser.

MATERIALS AND

METHODS

The texture of a plastic eraser made from polyvinyl chloride is similar to that of human costal cartilage. The first step of the training is carving out the sixth through eighth rib cartilages from a block of plastic eraser. The second step is a fabrication of the framework from plastic rib cartilages, referring to a template from the intact auricle.

RESULTS

As plastic erasers are inexpensive and universally available, inexperienced surgeons can repeatedly perform this framework training. Following several of these training sessions in developing nations, the co-authors and local surgeons successfully performed their microtia reconstructions in a reasonable operative time.

CONCLUSIONS

This realistic carving model allows surgeons to gain experience before performing an actual ear reconstruction, even in resource-constrained circumstances.
