PROBLEM TO BE SOLVED: To provide a sellaturcicu base prosthesis which can be deformed into a desired shape and size in a short time. SOLUTION: This sellaturuca prosthesis 1 include an approximately semicircular, first plate-shaped member 2a having an operational opening 40a therein an approximately semicircular, second plate-shaped member 2b provided to partially overlap with the first plate-shaped member 2a and having an operational opening 40b therein and a journal part 3 provided on the peripheral edges of the first and second plate-shaped member 2a, 2b at their overlapping portions. In this case, the second plate-shaped member 2b is rotatable about the jornal part 3 relatively to the first plate-shaped part 2a and is approximately circular.
