Vocal Cord Paralysis:   (Back To Top)  
This section contains six videos showing different types of
laryngeal ( or voice box ) paralysis.  There are five videos with a unilateral paralysis of the true vocal cord, four of these have paralysis of the recurrent laryngeal nerve and one of the superior laryngeal nerve.  One video show a bilateral paralysis due to lung cancer.   Paralysis of the recurrent laryngeal nerve can present in two ways.  One is an adductor muscle paralysis where the cords are abducted or moved away from the midline.   If uncompensated, this type of paralysis produces a weak voice but good airway.  Compensation can produce a stronger voice by the working true vocal cord moving across the midline to meet the lateralized cord, or by phonating with the false vocal cords.    

 If a bilateral adductor muscle paralysis is present, the voice will be weak and breathy but the patient will have a good airway.  The other type of paralysis is abductor muscle paralysis where the paralyzed true vocal cord is adducted or near the midline.  In this case the voice is strong but raspy.  If a bilateral abductor muscle paralysis is present, the voice will be good but serious airway obstruction may occur.  In a superior laryngeal nerve paralysis, the supraglottis is shifted away from the paralyzed side and the true vocal cord is shortened and lax on the innervated side.

Vocal Cord Paralysis Video  (Paramedian Paralysis - Partially Compensated Mildly Weak Voice) This patient is a 44 year old with a 35 pack year history of smoking and a 3 month history of a hoarse voice and mild aspiration of liquids.  This video shows the patient's chest CT scan and the endoscopic video of the patient's larynx during vocalization.  The patient has partially compensated vocal cord function and a paralyzed left true vocal cord in the paramedian position.  This is an extended 93 Second video including the CT Scan and Laryngoscopy Video.

Vocal Cord Paralysis Video  (Abductor Muscle Paralysis  - Strong Raspy Voice)  This patient is a 75 year old with a left true vocal cord paralysis from metastatic breast carcinoma to the mediastinum.  In this area the cancer causes the paralysis by damaging the recurrent laryngeal nerve nerve as it loops around the aortic arch.  It was an abductor muscle paralysis and the left vocal cord had a central position giving the patient a good voice.   Search PubMed for Vocal Cord Paralysis

Bilateral Vocal Cord Paralysis Video  ( Bilateral Adductor Muscle Paralysis - Weak Breathy Voice)  This video shows the function  of a larynx which has paralysis of both true vocal cords.  The patient was a very heavy smoker and developed lung cancer.  First, the patient's left cord became paralyzed and then his right.  As can be seen in the video, the cords quiver but do not consistently touch each other during phonation.  The patient has an adductor muscle paralysis (the true vocal cords are lateral and not touching in midline).  In this type of paralysis, the patient has a good airway but a very weak voice.  If the nerves (recurrent laryngeal nerves) to the vocal cords were completely transected, the patient would have primarily an Abductor Muscle paralysis with the cords touching each other in the midline.  In this case, the patient's voice would be strong but he would have severe airway obstruction.     Search PubMed for Vocal Cord Paralysis
