DESCRIPTION: Injection laryngoplasty is a technically demanding procedure requiring precise localization of the injection needle as well as knowledge of the vocal fold anatomy. We present a novel instructional model that combines light-guided visualization with a 3D-printed laryngeal framework using inexpensive materials. This model allows learners to practice injection techniques in a low-risk setting, with real-time feedback through direct visualization

OUTCOME OBJECTIVES: By the end of this lecture, attendeses should be able to:

A. Identify key laryngeal landmarks relevant to injection laryngoplasty

B. Know what materials are needed to build their own injection laryngoplasty trainer

C. Learn how to create a 3D printed laryngeal model

D. Utilize light-guidance to enhance needle placement accuracy
