Yes. Both my boys had tongue and lip ties. DS1 wasn't diagnosed till about 2.9 years old, whereas DS2's tongue tie was identified at about 4 days old or so, because I was pretty confident DS1 had one, though it hadn't been diagnosed. DS2 had his TT cut almost straight away at an NHS hospital. Feeding improved, but didn't improve massively.
We then had both boys' lip ties and DS1's tongue tie revised by Malcolm Levenkind (sp?), the private dentist in London who does revisions of ties. DS2's breastfeeding improved noticeably after the lip tie revision, but still wasn't right.
So about a week after the revision we had a few sessions with an osteopath, Camilla Nicholls, who has a practice in London and who is familiar with post-TT babies (from memory, she works with a private lady whose name is fairly familiar here - or was a few years ago - who does baby TT revisions, though I can't remember her name. Diana someone maybe?) After a couple of sessions of seeing her, DS2's feeding improved massively.
In hindsight, I wished I'd done what I'd often heard recommended to do, which was to see an osteopath for 2 or 3 sessions before the TT procedure, and then a couple more the day or two after the TT was cut. I don't know how long after the procedure the osteopathy might help. I've only ever tried osteopathy once before (for my then chronically non-sleeping baby DS1, and it didn't seem to help). It pretty much fixed the residual discomfort with DS2's feeding.
I have heard concerns somewhere (here?) that there might be some negative side-effects from lip tie revision, but I can't remember what they were and I hadn't heard of them at the time. From memory, DS2's lip tie wasn't as bad as DS1's. I should note that although I could tell that DS2's feeding wasn't right, it was mostly just uncomfortable rather than any specific problems. I was on the look-out for it because I'd wondered about DS1 having a tongue tie when he was younger (clicking or slurping sometimes at the breast) and by the time he was a toddler it was obvious he had something wrong with his tongue.
When he was about 2.5 he was diagnosed with verbal dyspraxia (apraxia) and the speech therapist said he had very limited horizontal movement of his tongue. Cutting the TT a few months later did seem to improve his ability to pronounce words a bit; it also completely stopped his constant drooling and improved his ability to chew and swallow food (before, big lumps of things like banana would sit on the back of his tongue rather than being swallowed).
Some TTs can regrow, or if things in the mouth are very tight, I think it's possible for a TT revision not to be able to deal with all of the tongue tie because it's hidden/not available to be seen. I suspect that was the case for DS1, who now still has a tongue tie despite it having been revised before. I don't think it's regrown, but I think that the general muscle tightness in his head/neck might have meant that the dentist couldn't access it all. When he had osteopathy starting a week after the revision, the osteopath said that at the end of the session, his muscles etc would be much looser and more relaxed, but by the start of the next session (the following day) they were back to being just as tight again. My guess is that was because there was still a partial tie there though it couldn't be seen or felt. For DS2, on the other hand, things that became looser stayed looser. I don't know much about the science, though, and I think both of their ties were anterior ones.
