Abstract

Multidisciplinary cooperation in health care requires a solid knowledge in the basic sciences for a common ground of communication. In speech pathology, these fundamentals improve the accuracy of descriptive diagnoses and support the development of new therapeutic techniques and strategies. The aim of this study is to briefly discuss the benefits of hands-on education on laryngeal anatomy and voice physiology in Brazilian graduate programs in speech pathology, as well as to describe a simple prototype that can be used as a useful educational tool for this purpose. The laryngeal anatomic support device was designed to provide a vertical frame to hold human or mammalian larynges with no preservation treatment, with the goal of allowing good visualization of the vocal folds during artificial phonation. The device was designed to provide the user the ability to manipulate the soft and cartilaginous structures of the larynx with near-natural biomechanical properties. The description of the project is detailed to allow the reproduction of this simple and inexpensive device. It may be used as an experimental feature in a variety of settings, from high-school programs to experimental research methods, and may suit a wide array of different educational models.
