Zusammenfassung
Die Dehiszenz des superioren Bogengangs ist ein noch nicht allzu lange bekanntes Krankheitsbild mit schall- und druckinduziertem Schwindel, Autophonie, Hörminderung und erniedrigter Knochenleitungsschwelle. Sie stellt eine wichtige Differenzialdiagnose zur Otosklerose und offenen Tube dar. Die Diagnostik besteht in audiometrischen Testungen, der Nystagmusprovokation, einer Feinschichtcomputertomographie und vestibulär evozierten myogenen Potenzialen. Eine Heilung ist durch operativen Verschluss der Dehiszenz möglich. Wir stellen das Krankheitsbild anhand eines typischen Fallberichts vor.
Abstract
Superior semicircular canal dehiscence syndrome is a clinical picture with sound and pressure-induced vertigo, autophony, hearing loss and a lowered bone conduction threshold. It is an important differential diagnosis to otosclerosis and patent eustachian tube. Diagnostic investigations include audiometric testing, nystagmus provocation, computed tomography and vestibular evoked myogenic potentials. Surgical repair of the dehiscence represents a curative therapeutic option. We describe the disease symptoms on the basis of a typical case.
