Dr. Crumley has a lifelong interest in disorders of the Recurrent Laryngeal Nerve (RLN) - the nerve that causes the movement of the vocal cords and allows us to create voice.   Much of this interest is focused on the problem of Vocal Cord Paralysis, and resulted in his initial ground breaking research in laryngeal re-innervation.  This research resulted in a new approach to the management of vocal cord paralysis, by using the a nerve in the neck (ansa cervicalis nerve) to replace the injured/damaged RLN.   This operation, pioneered at U.C. Irvine, results in a re-innervated vocal cord.  Several centers in the U.S., Europe, and Asia have switched to laryngeal reinnervation for management of vocal cord paralysis, (from the previous older techniques of Teflon injection, Fat injection, and Gelfoam injection). Current Dr. Crumley is a  member of a research team studying the effects of reinnervation vs Medialization thyroplasty in a study at UC Irvine, and several other U.S. Universities.
