Improved stem of the prothesis for the reconstruction of the ossicular chain

An improved Total Ossicular Replacement Prosthesis (TORP) for reconstruction of an ossicular chain, said improved TORP comprising:

• a head formed by a single cartilaginous block and is provided with a first hole;
• a base formed by another cartilaginous block, provided with a second hole, comprising a same thickness as the head but with a smaller surface;
• a synthetic stem of cylindrical shape which comprising two sides and two blunt tips, wherein each blunt tip is provided on one side of said two sides, such that a first blunt tip is on a first side of the synthetic stem and a second blunt tip is on a second side of the synthetic stem that is opposite to said first side, wherein said two blunt tips are inserted, respectively, said first hole of the head and said second hole of the base;
• wherein said improved TORP is configured in such a way as to be able to position, respectively, said head under a tympanic membrane and said base above a plate of a stapes;
• such that, during a healing process, a perichondrium of the head is welded to the tympanic membrane and a perichondrium of the base is welded to a mucosa of the plate.
