Zusammenfassung. Mastodynie ist ein häufig auftretendes Krankheitsbild, das uns im klinischen Alltag regelmässig begegnet. Da die Ursachenpalette äusserst breit von physiologischen Veränderungen bis Malignität reichen kann, ist die Diagnosefindung nicht immer einfach. Der Ausschluss der Malignität führt bereits bei vielen Betroffenen zu einer grossen Entlastung und zu besserem Umgang mit den Beschwerden. Nach einer sorgfältigen Abklärung kann die adäquate Therapie je nach Form der Mastodynie eingeleitet werden. Grundsätzlich lässt sich sagen: Die medikamentöse Therapie der zyklusunabhängigen Form ist unbefriedigend, operative Vorgehensweisen sind bei symptomatischen Befunden zu diskutieren. Grössere operative Massnahmen stellen hingegen bei der zyklischen Mastodynie keine erfolgversprechende Option dar und hier ist strenge Zurückhaltung geboten. Nicht jede Mastodynie benötigt zwingend ein therapeutisches Vorgehen. Das Konzept muss individuell angepasst an den Leidensdruck festgelegt werden. Bekannt sind Spontanremissionen von ca. 20–30 %. Dabei steht die Remission der zyklischen Mastodynie in Zusammenhang mit hormonellen Ereignissen (z.B. Beginn Einnahme einer Antibabypille, Schwangerschaft, Menopause).
Aim: To evaluate the perioperative outcome and cosmetic outcome of prepectoral implant-based breast reconstruction using the TiLOOP® Bra Pocket.Background: Besides acellular dermal matrix (ADM), synthetic meshes have revealed good surgical and aesthetic outcomes. We present our data using TiLOOP® Bra Pocket, a ready-to-use mesh pocket which is made out of nonresorbable, titanized, lightweight polypropylene with a monofilament structure and designed to ensure optimal fixation of the breast implant following mastectomy. The idea behind the mesh pocket is to fix the implant to the muscle and provide coverage and stabilization for the implant by serving as an ´internal bra´, which will create an inferior and lateral sling to support the position and stability of the implant and prevent it from dislocating or twisting. Materials and Methods: A single-center retrospective study was performed to assess short-term complication rates and cosmetic outcomes in patients with immediate or delayed implant-based breast reconstruction using the TiLOOP® Bra Pocket after nipple- or skin-sparing mastectomy. The primary endpoint was complication rates, which were divided into major and minor complications during the first 6 months. Minor complications were defined as those treated conservatively, major complications were those requiring surgical therapy. The secondary endpoint was short-term cosmetic outcome after 6 to 12 months, which was judged by two professionals using the Harvard score (1 = poor, 2 = fair, 3 = good, 4 = excellent). Results: A total of 63 breasts (43 patients) were reconstructed by implant using the TiLOOP® Bra Pocket between 2018 and 2020, of which 57 were immediate reconstructions. Mean follow-up was 12 months. The overall complication rate was 30,2 % (n = 19/63). Major complications occured in 7 breasts (n = 7/63; 11,1 %) and minor complications occured in 12 breasts (12/63; 19,0 %). 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 6 cosmetic revision surgeries were performed (6/63; 9,5 %). Conclusion: Immediate prepectoral implant-based breast reconstruction with the TiLOOP® Bra Pocket seems to be a feasible method with moderate complication rates and good cosmetic outcomes. Careful patient selection and preparation techniques considering flap viability are vital in order to achieve acceptable complication rates and satisfying cosmetic results. Long-term follow-up is needed. The next follow-up will be performed after 24 months.
