Bilateral Cord Dysfunctions: Abductor Type Spastic Dysphonia

UCLA School of Medicine

Abstract

Unlike cord approximation disorders such as adductor type spastic dysphonia and vocal cord paralysis, which have been well defined, abductor type spastic dysphonia has received limited attention. This report presents voice symptoms, spectrographic data, indirect laryngoscopic observations, and case histories of two cases. Questions are raised as to whether there is a spastic component to this disorder, and if there is a specific age group affected.
