Over the last 10 years, immediate implant‐based breast reconstruction has become increasingly popular, with the aim to reduce the number of operations, operating times and days of convalescence, as well as to improve quality of life and cosmetic outcomes.1
With the development of new biomaterials, the creation of a submuscular pocket is possible, even without an expander.4 These developments allow for aesthetically pleasing, immediate breast reconstruction (with definitive implants) in only one operation (i.e. the one‐step technique).7
Compared with the expander‐assisted technique, the advantages of one‐step breast reconstruction have been widely proved and have demonstrated excellent cosmetic results and reduced capsular contracture, as well as reduced hospital length of stays and no additional surgery costs.9 Nevertheless, several complications may occur because of the release of the pectoralis major muscle, and physiotherapy rehabilitation is frequently required.11 The detachment of the pectoralis muscle with the aim of placing an expander/implant under the muscle can cause prolonged post‐operative pain.12
We propose a new conservative surgical technique that preserves the pectoralis major muscle. This new muscle‐sparing technique is possible due to the Braxon® non‐cross‐linked acellular dermal matrix (ADM) produced by Medical Biomaterial Products (mbp) GmbH, Neustadt‐Glewe, Germany, under the license of Decomed S.r.l., Marcon‐Venezia, Italy. The Braxon® pre‐shaped matrix wrap‐around breast implant is sutured with absorbable stitches to the superficial surface of the pectoralis major, avoiding the detachment of the muscle.
Therefore, this approach may offer the improved cosmetic outcomes that are associated with an ADM sling, without the surgical morbidity associated with creating a subpectoral pocket. Furthermore, there may be financial benefits associated with shorter operating times and reduced hospital stays. Thus, this innovation has the potential to improve patient care.
We performed a retrospective, three‐centre, proof‐of‐concept study (IDEAL stage 1)13 with a highly selected patient cohort; the objective of this study was to evaluate the new muscle‐sparing technique for breast reconstruction using a shaped ADM for total implant coverage.
