VALLEJO-VALDEZATE, Luis A et al. Design, 3D modeling and mechanoacoustical behaviour optimization of a new ventilation tube. Rev. ORL [online]. 2020, vol.11, n.4, pp.413-425. Epub 15-Mar-2021. ISSN 2444-7986. https://dx.doi.org/14201/orl.22759.
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 eardrumosicular 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.
