Building an Easy-to-Assemble, Low-Cost Phonomicrosurgery Dissection Model: A Technical Report From the University of Cartagena

In otolaryngology, training often involves simulation in animal specimens, human cadavers, and artificial models to facilitate learning surgical procedures, reducing the time needed to acquire essential skills. Simulated training has become integral to medical education, particularly in microsurgical techniques, such as microlaryngeal surgery. These procedures, also known as phonomicrosurgery, are performed on the vocal folds using microscopic visualization and precision instruments with long shafts and millimetric tips. In otolaryngology programs, ear surgeries were the first to be incorporated into temporal bone laboratories, making such training a standard requirement for all teaching institutions. Similarly, laryngeal models have been developed to support phonomicrosurgery training. However, these models are often expensive or technically complex to assemble, limiting their accessibility for many institutions. This report provides a step-by-step guide to building a phonomicrosurgery model designed for practicing various surgical techniques using porcine or human cadaveric larynges. The model reduces costs to approximately 20 USD, is constructed from readily available materials, and can be easily assembled by untrained personnel. It offers an accessible solution for enhancing phonomicrosurgical skills in otolaryngology residency programs.
