Abstract

Malformed ears of neonates can be effectively treated by employing an orthosis of suitable shape. Currently, we use orthoses made of nitinol shape memory alloy wire and have developed a computer-assisted design system to manufacture the orthosis. Using this method, extracted contours of the helix and auriculotemporal sulcus are approximated to spline, and orthosis shape can be designed by moving the control points of spline with reference to control points of the target auricular shape. The system also functions to evaluate the contact force between the orthosis and auricle. Using this system, orthoses were designed and manufactured for 16 patients with malformed ears. Treatment was more effective in cases where it was necessary to extend the helix.
