I have made no secret of the fact that I firmly believe in the existence of
lactiferous sinuses,
Dear Colleagues:
My understanding of what happened back in the 1800s is that anatomists
injected liquid wax into the ductwork through the nipple and when the wax
hardened, the shape of what was then called "sinuses" was seen.
To me, the only way to reconcile what I have seen and experienced with
the ancient anatomical work and Ramsey Geddes' new study is that the ducts near
the areola are capable of swelling temporarily to accomodate an intermittent
filling and emptying. That's why those places could be filled with wax, that's
why they aren't seen as structures during ultrasound, and that's why I had
little doughnuts around my nipples before feeds.
A sinus is a pocket, with firm walls. Lactiferous sinuses have flexible
walls, capable of more expansion than the other parts of the duct.
What do you all think?
warmly,
