A cranial prosthesis for implanting over a portion of a patient's skull includes a body having a first major surface configured for positioning against the patient's skull； a second major surface opposite to the first major surface and forming a contour along which the patient's scalp is disposed against； and an outer perimeter defining a boundary between the first and second major surfaces. A cavity is defined along a portion of the first major surface and is configured for receiving and covering a portion of a medical device extending outwardly from the patient's skull. A tapered region extends radially outward along the body toward the outer perimeter and tapers the contour of the second major surface to reduce visibility of bulging along the patient's scalp caused by the portion of a medical device extending outwardly from the patient's skull when the prosthesis is disposed over the implanted medical device.
