Objective: To evaluate the diagnostic application of external ear canal sound measurements in pulsatile tinnitus (PT).
Study Design: Retrospective chart review on a prospective series of sound measurements.
Setting: Tertiary referral center.
Objectives: This study aims to determine how prevalent suspected cognitive impairment is in older people visiting hearing aid dispensers, and to assess whether hearing aid dispensers' judgment on cognition was in accordance with the outcome of a cognitive screening.
Design: This observational study was conducted between April and May 2022.
Setting And Participants: Four private hearing aid retail stores in the Netherlands, where cognitive impairment was screened in people aged ≥60 years.
Objective: Patients with pulsatile tinnitus (PT) are often referred for digital subtraction angiography (DSA) to exclude cranial dural arteriovenous fistula (DAVF). Because DSA is not without risk, the authors studied the sensitivity and specificity of an automated detection algorithm that analyses external ear canal sound measurements to evaluate the presence of DAVF in PT patients.
Methods: Between 2015 and 2021, external ear canal sound measurements of 72 PT patients were collected prospectively at our tertiary tinnitus clinic preceding referral of these patients to the neurosurgical department for counseling about DSA.
Objectives: In this paper we describe an automated detection algorithm that objectively detects pulsatile tinnitus (PT) and investigate its performance.
Design: Sound measurements were made with a sensitive microphone placed in the outer ear canal in 36 PT-patients referred to our tertiary clinic, along with a registration of the heart rate. A novel algorithm expressed the coherence between the recorded sound and heart rate as a pulsatility index.
