Background
Approximately 80% of patients undergoing total mastectomy in the US opt for implant-based
breast reconstruction (IBBR). A two-stage reconstruction with tissue expander (TE)
remains the most common technique. Since the implementation of ADMs, a prepectoral
approach has gained popularity and is becoming the standard of care. Herein, we compared
the surgical and postoperative outcomes of prepectoral versus subpectoral two-stage
IBBR.
Methods
A retrospective chart review was performed between January 2011 and December 2020.
We included female patients undergoing immediate two-stage IBBR. The primary outcomes
of this study were to compare the 30-day morbidity and the overall rate of complications
during the first and second stages of reconstruction, and to compare the time to initiate
postmastectomy radiotherapy (PMRT). Propensity score matching was implemented.
Results
After matching, 154 reconstructions were analyzed, 77 in each group. The two matched
groups exhibited comparable (p > 0.05) characteristics for all analyzed demographic and intraoperative independent
variables. Reconstructions in the prepectoral group had a shortened median time for
drain removal (13-days vs. 15-days, p = 0.001). The intraoperative expansion volumes were higher in the prepectoral group
(300 ml versus 200 ml, p = 0.025). The 30-day morbidity and first- and second-stage complication rates were
not significantly different between groups. The time to start postmastectomy radiation
therapy (PMRT) was not significantly different between groups (134-days versus 126.5-days,
p = 0.58).
Conclusion
Prepectoral and subpectoral TE placement had comparable complication rates during
the first and second stages of IBBR. Timing for TE-to-Implant exchange and initiation
of PMRT were comparable between the two approaches.
