Yes, while having fixed retainers as well, I went from 38-39 to 42.3 intermolar width. Just know that tip of tongue should be behind the wire.

wow that's great! Do you also have a wire on the 6 front teeth or only 4 like Dr. Mike Mew recommends? And do you know by the way if it is also possible in adults not just to expand your palate but also make the part between nose and lips smaller through good oral posture. My face is really long. 

thanks so much for replying.

What is this retainer that Dr. Mew recommends?

A wire one, it is just a very small wire on the front teeth (on the inside of the mouth not visible). He had recommended to only do the front four teeth.

6 on both top and bottom. The appearance of a small philtrum comes from a forward maxilla, so I think it is possible. I did not really pay attention to my philtrum, so I don't know if it improved, but the front and side part of my cheekbones are much more prominent. The results really only started coming in after I started doing tongue exercises and placed my tip of the tongue in the correct position, so I believe tongue exercises are the best way to help you achieve your goals.
