how to recover mesh which is destroyed under pose mode

I have rigged my character with rigify addon, and I saved it after making some poses and closed blender. After when I reopened I found some parts of my character mesh have been gone. I tried to reset the pose by Alt+s, Alt+r, Alt+g but nothing happens. Please help.
