ABSTRACT:
An otoplasty for behind-the-ear provisions for hearing aids, with which a preferably flexible signal conductor coming from the behind-the-ear device, such as a sound tube, can be positioned in the auditory canal. The otoplasty is individually adapted to the anatomy of the patient. Its fixing part is essentially in the form of a hook that follows the outer edge of the patient's cavum conchae in an arch, at least in some areas. A limb that follows the edge of the cavum conchae becomes a bent transversal section above the patient's antitragus, traversing the cavum conchae, extending in the direction of the patient's porus acusticus externus and expanding at its end section which comes to rest in the upper area of the auditory canal, to receive the signal conductor.
