09-12, 10:45–11:15 (Europe/Istanbul), Laryngology 2
Description: The Neurolaryngology Study Group and the American Academy of Otolaryngology – Head & Neck Surgery has published recommendations on the use of Laryngology Electromyography (LEMG). We will discuss traditional and innovative applications of LEMG, like diagnosing vocal fold paralysis, predicting vocal fold recovery, guiding botulinum toxin injection for spasmodic dysphonia and performing vocal fold injections of temporary fillers for glottic insufficiency. We will share tips for integrating this technology into clinical practice, based on our experience published in peer reviewed literature. Pros and cons of LEMG will be reviewed.
Outcome Objectives:
- To examine the traditional applications for laryngeal electromyography, like diagnosing vocal fold paralysis and guiding botulinum toxin injection for spasmodic dysphonia
- To explore innovative ways to use laryngeal electromyography, like guiding filler injections for vocal fold paralysis and glottic insufficiency.
- To discuss the pros and cons of integrating laryngeal electromyography into clinical practice
Structure of the session:
Three expert laryngologists will discuss their experience with LEMG in their respective practices in Taiwan and Canada. Lectures will be based on their peer-reviewed publications in the literature.
