Breast reconstruction with TiLOOP® Bra: Another arrow in plastic surgeons' quiver?

BACKGROUND: The use of lower-pole sling products has made immediate breast reconstruction a feasible option in women undergoing skin-nipple sparing and skin-reducing mastectomies. To date, available data on the comparative efficacy of biological and synthetic meshes regarding postoperative complications are scattered and limited. METHODS: A systematic literature search was performed to screen three different databases (PubMed, Web of Sciences, and Embase) using the following keywords: "breast reconstruction" AND "TiLOOP®" OR "Titanium-Coated Polypropylene Mesh" OR "TCPM". The perioperative and demographic characteristics of patients, complications profiles, and patient-reported outcomes were considered. RESULTS: We initially identified 234 articles, of which only 41, including 3923 patients and 5042 reconstructed breasts, fully satisfied the inclusion criteria. CONCLUSION: TiLOOP® Bra could be considered a safe and aesthetically valid alternative to Acellular Dermal Matrices (ADMs) in non-smokers patients undergoing skin-nipple sparing and skin-reducing mastectomies and immediate reconstruction. In such populations, complications are more likely to develop in patients with extreme body mass index values. The incidence of seroma with TiLOOP® Bra is comparable to that of ADMs as it is the beneficial effect in radiated patients, where TiLOOP® Bra seems superior to implant alone reconstruction. It has a good bio-integration with host tissues and resistance to infections in patients with a weakened immune system as a consequence of oncologic perioperative treatments.

Meshed Dermal Sling for Prepectoral Breast Reconstruction.

The best breast reconstruction solution after mastectomy remains a topic of wide debate. Recently, the focus in the field of implant-based reconstruction has been on the increasing indications for prepectoral reconstruction. This offers undoubted advantages over subpectoral reconstruction, ranging from better aesthetic results and patient comfort to a less invasive procedure that spares the pectoralis major muscle, reducing pain and postoperative recovery time. The dermal sling is a reconstructive variant introduced by Bostwick in the 1990s and is commonly used to complete the subpectoral pocket in one- or two-stage reconstruction, creating a dual-plane reconstruction. This method may be indicated after mastectomy for both therapeutic and prophylactic purposes. It can also be used for unilateral and bilateral reconstructions. We propose a new meshed dermal sling technique that allows complete prepectoral reconstruction without the use of acellular dermal matrix, thus reducing the cost of reconstruction. It also allows the indication for complete prepectoral reconstruction to be extended to patients with medium breast volume and grade 1 or 2 ptosis, without the need to use acellular dermal matrix or the pectoralis major muscle to complete the breast pocket.

Immediate post-mastectomy prepectoral breast reconstruction with animal derived acellular dermal matrices: A systematic review.

BACKGROUND: Animal-derived acellular dermal matrices (ADMs) are increasingly being used in prepectoral direct-to-implant (DTI) breast reconstruction. However, the indications and complication profile associated with this type of reconstruction remain unclear. This study aimed to perform a systematic review of the available literature on the use of animal-derived ADM in prepectoral DTI breast reconstruction. METHODS: Three different literature databases, namely, PubMed, Web of Sciences, and Embase were screened using the following keywords: "immediate" AND "pre-pectoral" OR "prepectoral" AND "ADM breast reconstruction." Animal-derived ADM used (porcine - Braxon® and non-Braxon® - and bovine - Surgimend®) anthropometric information, clinical data, and complications profile were considered. RESULTS: A total of 340 articles were initially identified, of which only 45 articles (5089 patients and 6598 reconstructed breasts) satisfied our inclusion criteria. The most widely used ADM was Braxon® in the context of conservative mastectomies. In most studies, a subcutaneous layer > 1 cm and lack of previous radiotherapy were considered prerequisites for this type of reconstruction. An increased risk of complications was found in smokers, patients who underwent radiation treatment, patients with high breast volumes, and patients with cancers requiring axillary dissection. Data related to the role of diabetes, high body mass index, and breast implant size on surgical outcomes were instead inconcludent. Age was not directly proportional to the complications. CONCLUSION: The complications associated with different animal-derived ADMs are generally comparable. The profile of patients required for eligibility for this type of reconstruction appears to have been identified and is in line with current recommendations.
