The invention relates to an implant for ventilating the middle ear intended to be implanted into the cortical bone behind the ear. The implant comprises a main body (1, 8) which is made of, or covered by a layer of, a biocompatible material, which is provided with a longitudinal bore (5, 12) and which has a length sufficient to completely penetrate the cortical bone and to come into functional contact with the space wherein the mastoid cell system is located, beneath the cortical bone, when inserted into a hole made through said cortical bone. |
