Where did you read this? To my understanding, it is purely about the prospect of splitting suture. I think Jaw Hacks discussed this with Dr. Stephen Vaughan and Dr. Richard Ting, but I don't recall which clip it was. Also, if my memory serves me right, they stated that 25 is not a clear cut age, as it is a highly individual matter of the state of ones maxilla. This guy for example documented his MSE journey. He turned out to have a really thick maxilla, so he needed TWO(!) MSE:s, the second finally managing to split his suture.

Otherwise, how are you progressing? I don't remember if you have had any success with mewing or not.

Why do you want to do this treatment? It focuses on splitting the suture but I've seen people in their 40s achieving this with their tongue alone.  In Ronald Ead's case, it expanded his asymmetries as opposed to fixing them. It's an expensive treatment and people who have had it don't look that good, to be honest. If there are relapses in double jaw surgery patients I wouldn't be surprised if there's relapse with MSE treatment, both options fail to address proper oral habits (Tongue posture, chewing, swallowing) and nose breathing.

After making this post, I got a consultation with a leading MSE doctor and they did say that success rates start dropping in the late 20's.  So that's the answer I was looking for in making this thread, at least according to what professionals currently know.

I have seen Evan and the Jaw Hacks channel - they're great.  I believe there was a Jaw Hacks interview with Dr. Ting where he mentioned his youngest failure cases were in patients aged 27 and 29.  So the earlier the better.

Can you link to any examples of people in their 40's achieving suture splits with tongue alone? That's amazing.

I've been religiously correcting orthotropic problems for the last few years but feel like I'm not making much progress.  I do think people who have had MSE look better but more importantly all the successes seem to confirm larger nasal cavities post treatment which is probably the most important thing for me health-wise.

I only know of someone that achieved this with a Starecta Tailored rectifier. He managed to split the transverse palatine suture by wearing the splint. You can find the discussion on the Starecta Community Facebook group if you search "suture" and this was reported in 2015.
