Lateral Cricoarytenoid injuries – the missed nerve impairments
09-10, 10:45–11:15 (Europe/Istanbul), Laryngology 2

Description:

Evaluation of the cricoarytenoid muscle requires a specific approach to examination including listening to vocal tasks and visually recording respiration and phonation.

Background:

Neurological impairments of the anterior branch of the recurrent laryngeal nerve are the most missed neurologic injuries of the larynx. Motion of the vocal process can be difficult to view, often covered by the arytenoid during endoscopic examinations. Additionally, sudden subtle movement can be missed.

Outcome objectives:

The audience will learn specific visual techniques to identify this recurrent laryngeal nerve injury, including paresis, synkinesis and dyskinesis of the nerve.

  • One of the most important outcomes is to be patient during recording, getting close and recording longer.

  • Slow video review looking for nuances of vocal cord motion, comparing side to side and expected motion reveals important details.

  • Treatment options will also be discussed.

Addressing request for a keynote lecture. I think this is one of the most intriguing topics I am able to present.
James Phillip Thomas

Since 1999, my medical and surgical practice has been limited to voice care. I maintain an

informational web site on voice disorders - voicedoctor.net, preceptor medical students in their

early years at Oregon Health Sciences University, offer an international fellowship in laryngology as

well as short observerships to physicians, speech therapists, voice teachers and interested students.

I produce “voxdoc, the voicedoctor” on YouTube, including Laryngology 101, a series of learning

videos. I published “Why is there a frog in my throat? A guide to hoarseness.” I frequently lecture

internationally on laryngology and phonosurgery. I remain surprised at how much there is still to learn

about the larynx.
