Neurological Voice Disorders
Specialized diagnosis and Botox-based treatment for Spasmodic Dysphonia and Essential Voice Tremor.
Overview
Understanding Neurological Voice Disorders
Neurological voice disorders occur when conditions affecting the nerves or muscles of the voice box interfere with normal voice production. Common disorders include Spasmodic Dysphonia, Essential Voice Tremor, and other neurological conditions affecting the vocal cords. Patients may experience a strained, shaky, weak or unstable voice that can significantly impact communication and quality of life.
At Dr. Hans' Voice & Swallowing Centre, patients are evaluated by a fellowship-trained Laryngologist using advanced Video Stroboscopy, Flexible Laryngoscopy and specialized voice assessment to accurately diagnose these complex conditions and provide individualized treatment.

Common Questions
Frequently Asked Questions
Spasmodic Dysphonia is a neurological disorder in which involuntary spasms of the vocal cord muscles cause a strained, broken or effortful voice.
Essential Voice Tremor causes rhythmic shaking of the vocal cords, resulting in a quivering or unsteady voice. It may occur alone or as part of generalized essential tremor.
While these conditions are usually chronic, they can be effectively managed with treatments such as EMG-guided Botox injections and specialized voice therapy, allowing most patients to achieve significant improvement.
The benefits typically last 3–6 months, after which repeat injections may be required to maintain voice quality.
