An ossicular prosthesis including a head portion and a shaft portion, each formed of a biocompatible material, preferably a susceptible to human tissues adhesion, and an intermediate portion formed of a bendable biocompatible material. The intermediate portion includes a first end connected to the head portion, a second end connected to the shaft portion, and a bendable shank which permits adjustable of the angular orientation of the shaft portion with respect to the head portion, allowing the prosthesis to be implanted in a human ear with the head portion contacting the tympanic membrane or the malleus of the ear and with the shaft portion contacting the arch or limbs or the footplate of the stapes. The prosthesis head portion and shaft portion are preferably made of hydroxylapatite, to which human tissue adheres, aiding in securing the prosthesis in the middle ear.
