Cricopharyngeal dysfunction and vocal cord palsy cause dysphonia and recurrent aspiration pneumonia. Cricopharyngeal dysfunction may result from cerebrovascular disorders, pharyngolaryngeal tumor, muscular dystrophy, gastroesophageal reflux and trauma, and is caused by failure of cricopharyngeal relaxation during swallowing.

The cause of vocal cord palsy divided into two groups: 1) central orign, 2) peripheral orign. Among these peripheral origns, the most common cause is the surgical and non-surgical trauma, and cause dysphonia and aspiration due to injury of pharyngeal plexus.

Recently, authors have experienced a case of cricopharyngeal dysfunction and vocal cord palsy due to stab wound on neck, which was treated by cricopharyngeal myotomy and thyroplasty.
