How fast does it grow?

Does anyone know how fast the styloid process “grows”? It it normal, or within the realm of normal" to have a styloid measure 3.0 cm and then 5 months later measure 4.1 cm?

I don’t know, but that sounds alot! I’ve never come across any research into it, I know that EarMom’s son’s grew back pretty quickly, but then he was young & still growing himself.
There could possibly be inconsistencies with the measuring otherwise? Some radiologists count calcified stylo-hyoid ligaments along with the SP measurement, some measure seaorately…
But no, if that’s genuine, I wouldn’t think it was normal!

yeah inconsistencies in measurement of styloid are not new
