22 Symptoms Common to Patients with Superior Canal Dehiscence Syndrome

What are the main evidence-based symptoms reported by patients with superior canal dehiscence syndrome (SCDS) before surgery and without concomitant pathology?

Bottom line
This systematic review identified a 22-item common symptom set that can be used to create an evidence-based patient-reported outcome measure to evaluate health-related quality of life in SCDS.

Background: In SCDS, an absence of bone overlying the superior semicircular canal creates a third mobile window into the inner ear, contributing to a wide variety of auditory and vestibular symptoms, including hearing loss, autophony, pulsatile and nonpulsatile tinnitus, aural fullness, bone conduction hyperacusis, imbalance, vertigo, and oscillopsia. No scale currently exists that captures the broad variety of patient complaints in SCDS.

Study design: Database search of 66 articles describing 431 patients with SCDS performed on May 17, 2017.
