Question: A patient is referred to you for hoarseness and breathlessness. Laryngoscopy reveals an immobile right true vocal fold with normal function on the left. The patient has no history of thyroid surgery, thoracic surgery, stroke, or other neurologic diseases. What must you rule out prior to undertaking a medialization procedure? [Answer will be posted with next week's new question]

Answer to last week's question, The First Bite is the Deepest (November 2, 2015):

First bite syndrome is caused by the loss of sympathetic innervation to the parotid gland, resulting in unopposed parasympathetic tone. This causes a vigorous contraction of myoepithelial cells that can be painful.
