Botulinum toxin has been used successfully for decades to treat voice disorders such as adductor/abductor laryngeal dystonia, and more recently essential voice tremor. This session will delve into a systematic approach to technical execution and thoughtful analysis of response to treatment with the goal of consistent outcomes. We will focus on starting dose/titration dilemmas, strategies for troubleshooting suboptimal outcomes, and managing complications. Attendees will leave with a working knowledge of the art of using botulinum toxin injections for voice disorders.

Learning Objectives:

Develop a framework for integrating patient factors and goals into selection of a starting dose, appropriate counseling for treatment naive patients, and monitoring treatment response
Navigate dosing dilemmas during titration to an optimal therapeutic dose and modifying injection target/approach based on treatment response
Utilize appropriate strategies for troubleshooting suboptimal outcomes and complications of botulinum toxin injections
