Taubheit bei Hunden und Katzen: Ursachen, Diagnostik und Therapie

Zusammenfassung

Taubheit gehört zu den am häufigsten beobachteten sensorischen Defiziten bei Hunden und Katzen. Die Ermittlung des Ausmaßes und der Ursache einer Taubheit kann Aufschluss über eine potenzielle Therapie geben, dem Tierbesitzer den Umgang mit seinem Tier erleichtern und die Entscheidung über die Zuchtverwendung des Tieres beeinflussen. Die Elektroaudiometrie mittels BAER (brainstem auditory evoked response) ermöglicht eine objektive Beurteilung der Hörfunktion. Darüber hinaus können die Otoskopie und verschiedene bildgebende Verfahren wie die Computertomographie bei der Ermittlung der Taubheitsursache hilfreich sein. Während Schallleitungstaubheiten häufig therapierbar sind, gibt es bei sensorineuralen Taubheiten in den meisten Fällen keine zufriedenstellende Behandlungsmöglichkeit. Eine wichtige Aufgabe des Tierarztes besteht hier in der Beratung des Patientenbesitzers im Umgang mit seinem Tier.

Summary

Deafness is one of the most common sensory deficits in cats and dogs. Determining the scope and the cause of deafness is important for a possible therapy and can enable the handling of the animal by its owner as well as influence the decision about breeding with the affected animal. Electrodiagnostic testing using the brainstem auditory evoked response (BAER) enables an objective evaluation of the hearing function. Additionally, otoscopy and various diagnostic imaging techniques, including computed tomography, can help in determining the cause of deafness. While conductive deafness can often be treated, there is normally no satisfactory treatment for sensorineural deafness. In such cases, an important task of the attending veterinarian is to advise the owner on handling his/her animal.
