Details and patient eligibility

About

This study is for women scheduled to have immediate breast reconstruction following mastectomy using a tissue expander. The primary purpose of this study is to learn whether there are differences in the outcome between placing the tissue expander above the muscle or below the muscle. The study will evaluate pain, wellbeing, and overall satisfaction with reconstruction. A secondary purpose is to learn whether there are differences in complications and costs between the two locations.
