Abstract

Introduction and Objetive: We show a new trans-tympanic ventilation tube whose design and mass are intended to solve the undesirable effects that appeared during the insertion of currently commercialized ventilation tubes; We analyze its mechanical behavior in a 3D model of the ear in order to optimize its acoustic behavior. Methods: For the design of the tube an autoCAD software was used; The mechanical behavior was analyzed in a 3D dynamic computerized model of the human ear based on the finite element method (FEM). Results: The new ventilation tube has a size and mass significantly smaller than those currently available in the market, which causes less interference in the vibration of the eardrum-osicular system; Its design facilitates it to remain inserted while the patient's conditions so advise avoiding its fall into the middle ear cavity or its early extrusion. Conclusions: The biological and acoustic advantages of the new developed tube (with less mass and whose design avoids the complications of the current ones) can open a new possibility of treatment of chronic seromucous otitis media.
