Abstract:
1. A middle ear prosthetic device, comprising: a columellate prosthesis arranged to replace, in sound wave transmission, an ossicular chain of a middle ear with the exception of a stapes or at least a footplate of the stapes, a first end of the columellate prosthesis being connectable to the stapes or to the footplate; an annular element of bioinert metal insertable, by previous milling, into the an auditory tube at a position in which a neotympanum is to be formed, the neotympanum for functionally replacing a tympanum of the middle ear; an elastic elongated element of bioinert material, disposed transversely to the annular element, a first end of the elongated element being coupled to the annular element while a second end of the elongated element is spaced from the annular element to be free relative to the annular element, the elastic elongated element being connectable to a second end of said columellate prosthesis at or in a vicinity of the second end of the elastic elongated element; a tensostructure of wires of non-reabsorbable bioinert material, which extends through an interior of the annular element and is fixed to the annular element, the tensostructure of wires for supporting the neotympanum on a side of the tensostructure distal to the inner ear when the neotympanum is formed, wherein a distance between the wires being for providing a surgeon with a sufficient view of a surgical field and allowing required surgical maneuvers, the elongated elastic element interfering with the tensostructure; wherein the columellate prosthesis being configured to hang from the elastic elongated element; wherein each said wire of said tensostructure has a first end and a second end, wherein each said wire first end and each said wire second end is directly attached to said annular element to be under tension.
