Prospective Analysis of an Evidence-Based Symptom Set in Superior Canal Dehiscence Syndrome.

Introduction: Superior canal dehiscence syndrome (SCDS) is characterized by a defect in the bone overlying the superior semicircular canal. This third mobile window generates an abnormal low-impedance pathway for sound/pressure transmission into the inner ear resulting in the characteristic symptoms.

Objective: To perform a prospective analysis of symptoms in patients with SCDS.

Impact of Superior Canal Dehiscence Syndrome on Health Utility Values: A Prospective Case-Control Study.

Superior canal dehiscence syndrome (SCDS) is a condition characterized by a defect in the bone overlying the superior semicircular canal, creating a third mobile window into the inner ear. Patients can experience disabling symptoms and opt for surgical management. Limited data are available on the impact of SCDS on health-related quality of life (HRQoL) and disease-specific HRQoL more specifically.
