A facial respirator mask having a concave and rigid shell (1) with an aperture for connection to a ventilating apparatus (2), characterised in that the shape of the rigid shell (1) is arranged to encompass, in addition to the nose and mouth, the whole of the adjacent part of the face defined outwardly by the jugal bone, the temporal bone squama and the lower maxilla, so as to provide a continuous engagement between the inner surface of the shell and the bone structure of the face below the forehead. The mask may be made from a material capable of being shaped by moulding on a three-dimensional model of a human face, particularly by direct moulding on the patient's face.
