摘要
External auditory duct prosthesis (10) is in the shape of a trough made from a material capable of plastic deformation with virtually no elasticity, and with sufficient malleability to allow it to be shaped manually, at least at room temperature, using a template with a radius of curvature of at least 5 mm. External auditory duct prosthesis (10) is in the shape of a trough made from a material capable of plastic deformation with virtually no elasticity, and with sufficient malleability to allow it to be shaped manually, at least at room temperature, using a template with a radius of curvature of at least 5 mm. The material used for the prosthesis can be a metal, especially titanium, or an alloy with a shape memory effect, such as a titanium-nickel alloy containing 54.8 - 55.6 wt.% nickel and having a martensitic structure at body temperature. The prosthesis is made by rolling a metal plate with a curved end about its lengthwise axis.
