I've been in practice for 29 years now, and I don't think there's an 
increase in tongue-tie in that time, but I do THINK I'm seeing more 
torticollis, which I think is the major confounder to tt. The babies who 
come to me only after an unsuccessful frenotomy (GRR!) mostly have 
torticollis, which also stiffens the floor of the mouth on the affected 
(tilt) side. I wonder if the increase in sitting/standing and decrease 
in walking/squatting for work is behind this?

It can be really hard to tease out the strands. We have seen immediate 
changes in baby's sucking on ultrasound after frenotomy, and sustained 
changes 2 weeks later. Even 3-4 month olds change their sucking pattern 
relatively quickly if tongue tie is the only issue.  So far we've only 
published our methodology and sample results, but we hope to get back to 
work (COVID derailed all research at Columbia University) and keep 
collecting data.

So no real answer, except that if frenotomy works, it is likely that 
either it substantially changed the baby's ability to latch, or their 
ability to suck, or both.
