Naomi - Thanks for the question. It is a challenging one.
The reason it is so hard to answer is there are many unanswered questions -
These include:
What was the size and shape of the tissue expander? How much was it over inflated?
What is the shape and position of your other breast?
Are you planning on surgery on the other breast?
What is your normal breast diameter?
It would be simply a wild guess to provide you numbers without an examination.
Sorry we can't provide more information.
