We numerically show that zero-energy Majorana surface states are suppressed around a vortex in three-dimensional topological superconductors such as CuxBi2Se3 and Sn1-xInxTe. On the other hand, zero-energy Majorana bound states along the vortex line are robust against a cut on the surface. The suppression of the surface-bound states is similar to that with a magnetic impurity on the surface of a topological insulator. The suppression of the surface-bound states around a vortex can be observed as an unconventional energy dependence of imaging by scanning tunneling microscopy/spectroscopy.
