The Diagnostic Accuracy of Ankle Audiometry Performed With the B250 for Superior Canal Dehiscence Syndrome in Patients Affected by Pulsatile Tinnitus and/or Autophony Disorders
Starting soon · Not applicable
Conditions studied: Superior Canal Dehiscence Syndrome, Autophony, Pulsatile Tinnitus
In brief
The goal of this clinical trial is to learn if the ankle audiometry test performed with the B250 bone conduction transducer can identify patients with superior canal dehiscence syndrome from those without among subjects presenting with autophony (a hearing condition where you hear your own body sounds) and/or pulsatile tinnitus. The main question it aims to answer: • Can ankle audiometry performed with B250 identify the condition of superior canal dehiscence syndrome among patients with autophony and/or pulsatile tinnitus, with a significance level of 80% and power level of 15%? Study participants will undergo ankle audiometry testing with the B250 and the threshold in dB FL (at the ankle) for which the patient hears the sound in the target ear will be measured.
