Vocal cord paralysis

Case contributed by Dr Alexandra Stanislavsky


Patient presents with a hoarse voice. There is a recent history of total thyroidectomy.


The following features of right vocal cord paralysis are demonstrated:

  • dilatation of the right vallecula
  • fullness and medial displacement of the right aryepiglottic fold
  • thickening and medial displacement of the right vocal cord
  • dilatation of the right piriform sinus
  • enlargement of the right laryngeal ventricle.

There are surgical clips indicating prior thyroidectomy, and peri-operative injury to the right recurrent laryngeal nerve is the likely aetiology in this patient.
