Background and Objectives Capsular contracture is one of the most common complications of implant-based breast reconstruction and may result in breast deformity, pain, stiffness, and the need for revision surgery. Acellular dermal matrices (ADMs) may provide valuable support in revision procedures. The aim of this study was to evaluate the clinical outcomes of Braxon Fast in revision breast reconstruction and to compare outcomes associated with B-Lite lightweight breast implants with those of a historical control group treated with conventional implants. Materials and Methods A comparative observational cohort study was conducted, including a prospective group of 13 patients (15 breasts) undergoing revision breast reconstruction with B-Lite implants and a retrospective historical control group of 16 patients (20 breasts) treated with conventional implants. In both groups, the implants were wrapped with Braxon Fast ADM. Minor and major postoperative complications, including recurrent capsular contracture, were assessed, together with patient-reported outcomes using the BREAST-Q. Results In the B-Lite group, four cases of mild capsular contracture (26.7%) were observed, including one bilateral case; one patient required surgical revision without implant replacement. One case of Red Breast Syndrome (RBS) and one case of edema were also recorded, both managed conservatively. No skin ulceration or wound dehiscence occurred. In the historical control group, four cases of skin ulceration (20%) were observed; one required outpatient suturing, while another subsequently developed an infection requiring surgical revision and implant replacement. Two cases of mild capsular contracture, three cases of RBS, and one case of mild edema were also reported and managed conservatively. In both groups, BREAST-Q assessment showed an overall improvement in patient-reported outcomes postoperatively compared with preoperative assessment. Conclusions The use of Braxon Fast in revision breast reconstruction showed favorable preliminary clinical outcomes, particularly in the management of capsular contracture. No skin ulceration was observed in the B-Lite group, compared with 20% of breasts in the historical control group. However, the small sample size, non-randomized study design, retrospective nature of the control group, and potential heterogeneity between groups limit comparability and preclude attributing the observed differences to implant type. These findings should therefore be considered exploratory and require confirmation in larger prospective studies with standardized follow-up.
Background e obiettivi La contrattura capsulare rappresenta una delle principali complicanze della ricostruzione mammaria protesica e può determinare deformità, dolore, rigidità e necessità di revisione chirurgica. Le matrici dermiche acellulari (ADM) possono rappresentare un valido supporto nella chirurgia di revisione. Obiettivo dello studio è stato valutare gli esiti clinici dell’impiego di Braxon Fast nella ricostruzione mammaria di revisione e confrontare gli outcome associati a protesi a peso ridotto B-Lite con quelli di un gruppo storico trattato con protesi convenzionali. Materiali e metodi È stato condotto uno studio osservazionale comparativo di coorte, comprendente un gruppo prospettico di 13 pazienti (15 mammelle) sottoposte a revisione ricostruttiva con protesi B-Lite e un gruppo di controllo storico retrospettivo di 16 pazienti (20 mammelle) trattate con protesi convenzionali. In entrambi i gruppi la protesi è stata rivestita con ADM Braxon Fast. Sono state analizzate le complicanze postoperatorie minori e maggiori, inclusa la recidiva di contrattura capsulare, e gli outcome riferiti dalle pazienti mediante BREAST-Q. Risultati Nel gruppo B-Lite sono state osservate quattro contratture capsulari lievi (26,7%), comprendenti un caso bilaterale; in una paziente è stata necessaria una revisione chirurgica senza sostituzione protesica. Sono stati inoltre registrati un caso di Red Breast Syndrome (RBS) e un caso di edema, entrambi trattati conservativamente. Non si sono verificate ulcerazioni cutanee o deiscenze. Nel gruppo di controllo sono state osservate quattro ulcerazioni cutanee (20%), una delle quali ha richiesto sutura ambulatoriale e mentre l’altra si è successivamente complicata con infezione, rendendo necessaria una revisione chirurgica con sostituzione protesica. Sono state inoltre riscontrate due contratture capsulari lievi, tre casi di RBS e un edema lieve, gestiti conservativamente. In entrambi i gruppi il BREAST-Q ha mostrato un miglioramento complessivo degli outcome riferiti dalle pazienti nel postoperatorio rispetto alla valutazione preoperatoria. Conclusioni L’impiego di Braxon Fast nella chirurgia ricostruttiva di revisione ha mostrato risultati clinici preliminari favorevoli, in particolare nel trattamento della contrattura capsulare. Nel gruppo B-Lite non sono state osservate ulcerazioni cutanee, rispetto al 20% delle mammelle del controllo storico. Tuttavia, la ridotta numerosità campionaria, il disegno non randomizzato, la natura retrospettiva del gruppo di controllo e la potenziale eterogeneità tra i gruppi, limitano la comparabilità e non consentono di attribuire le differenze osservate alla tipologia di protesi. Questi risultati devono pertanto essere considerati esplorativi e necessitano di conferma mediante studi prospettici su casistiche più ampie e con follow-up standardizzato.
