What Is New in Laryngeal Dystonia: Review of Novel Findings of Pathophysiology and Novel Treatment Options

Purpose of ReviewThe aim of this review is to present the current literature on pathophysiology, evaluation, and management of laryngeal dystonia.Recent FindingsRecent evidence suggests loss of cortical inhibition, and sensory dysfunction plays an important role in the pathophysiology of laryngeal dystonia. New treatments addressing these changes include electrical stimulation for neuromodulation of the larynx, vibrotactile therapy, and sodium oxybate. Preliminary investigations are promising and these may impact the future of care for laryngeal dystonia patients.SummaryThe current literature emphasizes a new understanding of the pathophysiology of laryngeal dystonia which has led to investigation of novel therapies.
