Unilateral vocal cord paralysis refers to a medical condition characterized by the paralysis or immobility of one of the vocal cords, which are responsible for producing sound during vocalization. In this condition, only one vocal cord is affected, leading to various voice-related problems and potential difficulty in breathing.
The vocal cords, also known as vocal folds, are located within the larynx and play a vital role in producing voice and speech. They are positioned next to each other and vibrate together to create sound when air passes through them. However, in cases of unilateral vocal cord paralysis, one of the vocal cords is unable to move properly or remains in a fixed position.
The causes of unilateral vocal cord paralysis can vary and may include neurological disorders, trauma or injury to the larynx or vocal cords, tumors or growths, viral infections, or damage to the nerves supplying the vocal cords. Common symptoms include hoarseness of voice, breathiness, reduced vocal volume, and difficulty with vocal projection. In more severe cases, individuals may experience shortness of breath, coughing, choking, or a weak voice.
Treatment options for unilateral vocal cord paralysis depend on the underlying cause and severity of the condition. It may include voice therapy, surgical procedures to reposition the affected vocal cord, or interventions to improve vocal cord function. In some cases, if the paralysis is temporary or has a neurological cause, vocal cord function may recover on its own without the need for specific treatment.
