Abstract
A process for making otoplasty or adaptive ear pieces individually matched to the shape of an auditory canal and consists of the following steps: a) direct or indirect tracing is provided of the shape of the auditory canal and conversion of the values obtained into digital form; b) conversion of the digital representation of this shape into a multi-dimensional computer model of the outer shape of otoplasty or adaptive ear piece; c) selection of the various components/functions for the inside of the computer model with simultaneous establishment of the wall thickness and optimization of the positions of the components/functions for best possible operation and minimum bulk; d) computer controlled production of an otoplasty or adaptive ear piece from the data thus obtained from the optimized, three-dimensional computer representation of the otoplasty or adaptive ear piece.
