Abstract: A prosthetic element enables the stapes footplate to be connected to the foot of a middle ear ossicular prosthesis. The prosthetic connection element is of biocompatible material and forms part of the foot or is connected or connectable to this latter, and includes a body provided with a flat surface intended to rest on the footplate and having an area sufficient to prevent reabsorption of the footplate osseous tissue as a result of the pressure which the ossicular prosthesis exerts on the footplate. The prosthetic element includes at least two pointed projections projecting from the flat surface and to penetrate the footplate.

Abstract: A middle ear prosthetic device including: a columellate prosthesis, one end of which is connectable to the stapes or to its remaining footplate; an annular element of bioinert metal insertable into the auditory tube after suitable milling; an elastic elongated element of bioinert material, disposed transversely to the annular element, a first end of the elongated element being rigid with the annular element while its second end is free and to it there being connected the other end of the columellate prosthesis; for supporting the neotympanum, a tensostructure of wires of non-reabsorbable bioinert material fixed taut to the interior of the annular element to support the neotympanum, the distance between the wires being such as to provide the surgeon with a sufficient view of the surgical field, the elongated elastic element interfering with the tensostructure.

Abstract: The middle ear prosthetic device comprises: a columellate prosthesis arranged to replace the ossicular chain of the middle ear with the exception of the stapes footplate or the entire stapes, a first end of this prosthesis being intended to be inserted into a hole provided in the footplate or to rest on the footplate itself, or to be connected to the stapes capitellum respectively; an annular element of bioinert metal insertable into the auditory tube at the position in which the neotympanum is to be formed; a tensostructure of non-reabsorbable bioinert material, which extends into the interior of the annular element and is fixed to this latter, the tensostructure presenting apertures which provide the surgeon with a sufficient view of the surgical field and allow the required surgical manoeuvres; first and second means for connecting the second end of the columellate prosthesis and the neotympanum to the tensostructure respectively.

Abstract: The middle ear prosthetic device comprises: a columellate prosthesis (22, 22A) arranged to replace the ossicular chain of the middle ear with the exception of the stapes footplate (24) or the entire stapes (36), a first end (30; 30A) of this prosthesis (22; 22A) being intended to be inserted into a hole (32) provided in the footplate (24) or to rest on the footplate itself, or to be connected to the stapes (36) capitellum respectively; an annular element (110) of bioinert metal insertable into the auditory tube at the position in which the neotympanum (18) is to be formed; a tensostructure (115) of non-reabsorbable bioinert material, which extends into the interior of the annular element (110) and is fixed to this latter (110), the tensostructure (115) presenting apertures which provide the surgeon with a sufficient view of the surgical field and allow the required surgical manoeuvres; first (138) and second (142) means for connecting the second end of the columellate prosthesis (22; 22A) and the neotympanum

Abstract: In the middle ear ossicular chain prosthesis, the tympanic end part (12), a face (14) of which makes contact with the tympanic membrane, is formed of ceramic hydroxylapatite. The constituent ceramic hydroxylapatite of the tympanic end part is porous with a pore size of between 100 and 400 micrometres.

Abstract: A middle ear prosthesis comprises a circular ring of substantially rigid synthetic material of a type able to bond to the osseous tissue if placed in contact with it; an elastic membrane of synthetic material compatible with the human body and fixable to the ring to close it; a columellar element of material compatible with the human body comprising a rigid but curvable intermediate portion; first connection means for connecting the intermediate portion to the central region of the membrane; and second connection means for fixing the intermediate portion to the stapes or to that part of it which remains.
