Aphonia paralyticas, also known as vocal cord paralysis, is a condition in which one or both vocal cords are unable to move. The resulting hoarseness or complete loss of voice can be caused by nerve damage or injury to the vocal cords. Some other terms for this condition include laryngeal paralysis, vocal fold immobility, and paresis of the larynx. Treatment options may include speech therapy, medication, or surgery depending on the severity and cause of the paralysis. It is important for individuals with aphonia paralyticas to seek medical attention as it can impact their ability to communicate effectively and may have underlying health implications.
