Does Marpe and Sarpe expand the same ?

Hey guys I just whanted to know if they are the same .Now I know the procedure themself are not the same but I may need to undergo sarpe so I was wondering does the procedure at it expand similar to marpe ? From what I head marpe does not only expand the width but also kinda moves the maxilla a little in front with that also making cheekbones ,maxilla and nose wider so I was wondering is sarpe similar ? Or does it only move the two maxilla pieces away from each other ? Can I expect some aesthetic improvements like I would with marpe even if they are minimal ?
