I have read that PAH is less rare since using the new CoolSculpting applicators?

The condition itself - PAH - is quite rare in general. I don't think the new applicators have changed the statistical likelihood of getting PAH.

The company reports a much reduced incidence of PAH (paroxysmal adipose hypertrophy) using the new applicators though in my practice I have only seen 1 case of PAH in 5 years.

I have not seen any PAH with CoolSculpting using the new applicators.  To be fair though, I also did not see any with the old applicators, although I know some physicians did.  

Hi, thanks for the question.
No, I have not seen PAH with the new applicator.  I think the reduction in the vacuum pressure has reduced the incidence, although I have not seen any studies on it.
Best of luck,

Thus far, there have been no reported true cases of PAH after being treated with the Cool Advantage Coolsculpting Applicators. Even with the legacy suction applicators, PAH was very rare occurring in just .025% of treated patients. There are now protocols in place to correct PAH.
