Paresis22

• Vocal cord paralysis , or vocal cord paresis, describes an impairment in the ability to control the movement of the vocal cords, resulting in changes in the voice and airway problems (e.g., dyspnea, dysphonia). (ckbhospital.com)
• Vocal fold (or cord) paresis and paralysis result from abnormal nerve input to the voice box muscles (laryngeal muscles). (midwestsinus.com)

• What Nerves Are Involved In Vocal Fold Paresis/Paralysis? (midwestsinus.com)
• Since the cricothyroid muscle adjusts the tension of the vocal fold for high notes during singing, SLN paresis and paralysis result in abnormalities in voice pitch and the inability to sing with smooth change to each higher note. (midwestsinus.com)
• Sometimes, patients with SLN paresis/paralysis may have a normal speaking voice but an abnormal singing voice. (midwestsinus.com)
• Consequently, the recurrent laryngeal nerve is involved in majority of cases of vocal fold paresis or paralysis. (midwestsinus.com)
