Prepectoral implant-based breast reconstruction with TiLOOP® Bra Pocket - a single-centre retrospective study.

Background: Prepectoral implant-based reconstruction using synthetic meshes is feasible with good outcomes. We present our data using TiLOOP® Bra Pocket, a novel ready-to-use mesh pocket which acts as an internal bra and prevents the implant from dislocating or twisting.

Materials And Methods: A single-centre retrospective cohort study was performed to assess short-term complication rates and cosmetic outcomes in patients with prepectoral implant-based reconstruction using the TiLOOP® Bra Pocket. The primary endpoint was complication rates during the first 6 months. The secondary endpoint was the cosmetic outcome after 6 to 12 months, which was judged by two breast surgeons using the Harvard score.

Results: A total of 63 breasts (43 patients) were reconstructed using the TiLOOP® Bra Pocket between 2018 and 2020, 57 were immediate reconstructions. The overall complication rate was 30,2% (n = 19/63). Major complications occurred in seven breasts (n = 7/63; 11,1%) and minor complications occurred in 12 breasts (12/63; 19,0%). The unplanned revision rate was 12,7%. The cosmetic outcome was good (Harvard score: mean 3, range 1-4; SD 0,75). Seventeen cosmetic complications were observed (17/63; 27,0%) and six cosmetic revision surgeries were performed (6/63; 9,5%).

Conclusion: The use of the TiLOOP® Bra Pocket is convenient and standardized because the pocket is preformed and does not require to be sewn first. Cosmetic outcome is good; however, the surgical morbidity needs to be addressed in future reconstructions. Careful patient selection and preparation techniques are vital in order to achieve acceptable complication rates and satisfying cosmetic results.
