Abstract
An otoplastic for production of behind-the-ear hearing aids. The hearing aid includes a preferably flexible signal conductor, such as e.g. an acoustic tube positioned in the auditory canal, whereby the otoplastic matches the individual anatomy of the patient and its locating part is in the form of a clip, which, at least partly arched, follows the outer edge of the cavum conchae. A branch which following the edge of the cavum conchae transforms, above the antitragus, into a bent crosspiece traversing the cavum conchae and extending in the direction of the porus acusticus externus. The end section of said crosspiece lies in the upper section of the auditory canal and widens to accept the signal conductor.
