Abstract
Objective: To demonstrate a practical and inexpensive surgical simulator model for the practice of tympanotomy with grommet tube placement. Methods: Experimental development of a model for surgical training, built from an infrastructure with two wooden platforms, one as a base and one as a support for the mold, interconnected by a hinged metal rod. The mold was formed from sawed syringes at a length of 2.5 cm, with a vinyl polychloride membrane ring fixed with a plastic tie at its tip, simulating respectively external ear canal and tympanic membrane. Results: The simulator after mounting allows the practice of the desired procedure, as well as others such as aspiration, removal of cerumen and foreign bodies from the external ear canal, and can be performed with the aid of both the microscope and rigid endoscope. Conclusion: The model is a cheap and practical alternative to tympanotomy training with grommet tube placement and other routine otorhinolaryngological procedures, and training using the simulator allows the user to master the necessary skills and become familiar with the equipment and instruments to perform these procedures in the real surgical environment.
