Unilateral Vocal Cord Paresis is a medical condition that refers to partial paralysis or weakness of one of the vocal cords. The vocal cords, located in the larynx or voice box, are responsible for producing voice by vibrating together as air passes through them. When an individual experiences unilateral vocal cord paresis, only one of the vocal cords is affected, resulting in a disruption of normal vocal cord movement.
This condition can be caused by various factors, including damage to the nerves that control the vocal cord muscles, injury to the vocal cords themselves, or certain medical conditions such as stroke, viral infection, or tumors. The symptoms of unilateral vocal cord paresis may include changes in voice quality, hoarseness, breathiness, difficulty speaking loudly or projecting the voice, and vocal fatigue.
Diagnosis of this condition typically involves a thorough evaluation by an otolaryngologist (ear, nose, and throat specialist) who will examine the vocal cords using specialized instruments. The evaluation may also include additional tests such as laryngeal electromyography to assess the function of the vocal cord muscles.
Treatment for unilateral vocal cord paresis aims to improve vocal cord function and minimize symptoms. It may involve voice therapy to strengthen the unaffected vocal cord and learn techniques to compensate for the weakness of the affected vocal cord. In some cases, surgical intervention may be necessary to address any structural abnormalities or to reposition the affected vocal cord. Overall, the prognosis for individuals with this condition varies depending on the underlying cause and the severity of the vocal cord paresis.
