Break Ya Neck

Question:  A 48 year old man trips near the bottom of his stairs and falls down, striking his anterior neck on the edge of a table.  Immediately he notes a change in voice but no breathing difficulties.  At his wife's urging, he presents to the local emergency department where he is evaluated with a CT of the neck.  This reveals a non-displaced fracture of the thyroid cartilage.  Endoscopic examination reveals a small endolaryngeal hematoma with a mucosal tear.  What is your next step in management?  [Answer will be posted with next week's new question]

Answer to last week's question, Time to Bear Down (Apr 6, 2015): 

Valsalva maneuver for suspected encephalocele.  Expansion of the mass with the subsequent increase in intracranial pressure would constitute a positive Furstenberg's sign.
