Purpose The rates of patients undergoing implant based breast reconstruction following mastectomy is steadily increasing in Australia with studies of the Australian Breast Device Registry showing the majority of prosthetic based breast reconstruction being performed is two-staged or delayed reconstruction with tissue expanders (TE), when compared to direct to implant reconstruction (DTI). The literature shows an overall a decreased patient satisfaction with TE when compared to DTI. Furthermore, there is increasing use of magnetic resonance imaging (MRI) for breast cancer surveillance, and currently available TE contain magnetic ports which make them MRI unsafe. Methodology Retrospective single-centre study at Chris O’Brien Lifehouse of consecutive patients undergoing TE based breast reconstruction within a 24 month period from September 1 2021 - Sept 1 2023. BREAST-Q patient-reported outcome measure (PROMs) are performed at 2-6 weeks and 1 year post-operatively and these outcomes will be reviewed. Method of surveillance imaging use will be collated, with any delay to imaging and diagnosis of recurrence. Results Approximately 60 patients will have undergone TE based breast reconstruction over this period at our institution. The authors are currently collecting the PROM data and data on delay on surveillance imaging. Conclusion. With the increasing rates of post-mastectomy breast reconstruction, and especially TE based reconstruction in Australia it is important to assess patient reported outcomes following surgery, as well as complication rate. Furthermore, with the increasing use of MRI in the surveillance of breast cancer, it is crucial to assess if there is delay to imaging due to the presence of a TE.
