How Much Saline is Placed in Expander at Time of Surgery?

As noted, this may vary greatly depending upon a number of factors at the time of surgery and your anatomy.  In general, more fluid may be able to be placed if an ADM (acellular dermal matrix) product was used.  This may allow complete coverage of the tissue expander with a larger initial volume forming more of a breast mound at the time of surgery.  This is quite variable and varies among surgeons.

The amount of saline injected into a tissue expander at the time it is placed can vary depending on many factors: amount of coverage of the expander by the pectoralis major, viability of the mastectomy skin flaps, whether it is a delayed vs immediate reconstruction, etc.  Most often, less then 100 cc's of saline are placed, but like I said, that will vary bsaed on the judgment of the surgeon

A tissue expander is a temporary implant, which has a "port" where saline can be injected into it at regular inervals to expand skin. With breast reconstruction, the initial volume of saline placed depends on several factors. It is imprtant to avoid putting any tension on the overlying skin, so judgment is used on a case by case basis.
