Voice Disorders
Voice disorders (pronunciation: /vɔɪs dɪsˈɔːrdərz/) are a category of pathological conditions that affect the vocal cords and other structures within the larynx (pronunciation: /ˈlærɪŋks/), which can result in a change in vocal quality, volume, pitch, or flexibility.
Etymology
The term "voice disorders" is derived from the Middle English word "vois", which means sound or tone, and the Latin word "disordine", which means irregularity or disturbance.
Types of Voice Disorders
There are several types of voice disorders, including:
- Vocal cord nodules and polyps: These are noncancerous growths on the vocal cords that can cause a raspy or breathy voice.
- Vocal cord paralysis: This occurs when one or both vocal cords cannot move. It can cause a soft, breathy voice and swallowing problems.
- Spasmodic dysphonia: This is a neurological disorder that causes involuntary movements of the vocal cords during speech.
- Laryngitis: This is an inflammation of the vocal cords, usually caused by a virus, which can result in a hoarse voice or temporary loss of voice.
