Brief summary
This is the first prospective randomized and controlled study on the efficacy and safety of TiLOOP® Bra mesh in patients with expander-implant breast reconstruction. The investigators hypothesize that incoporating TiLOOP Bra mesh with tissue expanders will reduce the rates of capsular contraction, improve the efficiency of expansion and provide better aesthetic result.
Interventions
The tissue expander is inserted with TiLoop Bra mesh in the first stage of reconstruction immediately after nipple/skin-sparing mastectomy. The tissue expander is placed sub-pectoral.
The tissue expander is inserted without TiLoop Bra mesh in the first stage of reconstruction immediately after nipple/skin-sparing mastectomy. The tissue expander is placed sub-pectoral and covered by muscle/fascia.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Complication Rates | up to 24 months after surgery | complications related to the reconstructed breast, including flap complications, capsular contracture, surgical site infection, prosthetic malposition/extrusion, reconstruction failure, etc. |
| Expansion Efficiency | through study completion, an average of 1 year | percentage of average injected saline volume to total volume (E=average volume/ total volume)through study completion, an average of 1 year |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| psychological evaluation by Breast-Q questionnaire | from the completion of expander exchange up to 24 months after surgery | We use the Breast-Q questionnaire to evaluate patients' satisfaction via the reconstruction module of BREAST-Q. |
| total cost | from expander implation up to the completion of expander exchange,through study completion, an average of 1 year | total cost in RMB per captia |
| number of revision surgery | from the completion of expander exchange up to 24 months after surgery | To record the rate of surgical revision events on the breast including but not limited to fat tranplantation, reduction mammoplasty/mastompexy, contralateral augmentation, |
| number of occurrence of non-surgical site infection | from expander implation up to the completion of expander exchange, through study completion, an average of 1 year | post-operative occurrence of non-surgical site infection including but not limited pneumonia, urinary tract infection, etc. |
| number of occurrence of deep venous thrombosis | from expander implation up to the completion of expander exchange, through study completion, an average of 1 year | post-operative occurrence of deep venous thrombosis |
| aesthetic outcome graded by Harris evaluation score and Breast-Q questionaire | from the completion of expander exchange up to 24 months after surgery | Harris evaluation score was used to evaluate the aesthetic outcome of patients' reconstructed breasts, which was scored as excellent, good, fair, poor. Breast-Q questionaire was also used to evaluate the aesthetic outcome of patients' reconstructed breast. |
