Ahhh, now this is a different matter.  I've been known to have this problem
myself.  Accordingly, I resist the temptation to put my regulator near my
ears at the surface.  The same hollow head that has led me to dangerous
sports such as motorcycle racing, competitive water and snow skiing and
(shudder) diving, makes things blown out of the ears while blowing the nose
a known risk.  On the other hand, the air I store in my cranium does seem to
help stretch my air supply a bit futher and may even contribute to my highly
developed buoyancy control.  Something similar to the counter lung on a
rebreather, I believe.
