A promising new development are lightweight implants, whose filler material is one third lighter than conventional silicone gel. While these implants have been used primarily for aesthetic augmentation, a benefit could be expected particularly in post-mastectomy reconstruction. Materials and Methods: Since 2019, 92 operations using lightweight implants have been performed at our clinic, 61 of them for breast reconstruction after mastectomy. These have been compared to 92 breast reconstructions using conventional silicone implants. Results: The average volume of the lightweight implants was 30% higher than of the conventional implants (452\u200aml resp. 347\u200aml), whereas the implant weight was comparable in both groups (317\u200ag resp. 347\u200ag). Grade 3-4 capsular fibrosis was seen in 6 cases in both groups; revision was required 9 times (lightweight implants) and 7 times (conventional silicone implants) during the follow-up period. Discussion: To our knowledge, this is the first study to investigate the use of lightweight implants in breast reconstruction. With exception of the filler material, the implants used in the two groups were comparable in shape and surface. The inserted lightweight implants had a greater volume but nearly the same weight as the conventional implants and were used in patients with a higher body mass index. Thus, lightweight implants were preferred in patients whose reconstruction required a larger implant volume. Conclusion: Lightweight implants are a new alternative for breast reconstruction especially in case that larger implant volume is demanded. The increased complication rate has to be verified in further studies.<\/jats:p>","DOI":"10.3233\/ch-239101","type":"journal-article","created":{"date-parts":[[2023,3,21]],"date-time":"2023-03-21T12:11:27Z","timestamp":1679400687000},"page":"103-109","source":"Crossref","is-referenced-by-count":2,"title":["Lightweight implants in breast reconstruction"],"prefix":"10.1177","volume":"84","author":[{"given":"Norbert","family":"Heine","sequence":"first","affiliation":[{"name":"University Center for Plastic, Reconstructive, Aesthetic and Hand Surgery, University Hospital Regensburg and Caritas Hospital St. Josef, Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vanessa","family":"Brebant","sequence":"additional","affiliation":[{"name":"University Center for Plastic, Reconstructive, Aesthetic and Hand Surgery, University Hospital Regensburg and Caritas Hospital St. Josef, Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephan","family":"Seitz","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Caritas Hospital St. Josef, University of Regensburg, Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreas","family":"Eigenberger","sequence":"additional","affiliation":[{"name":"University Center for Plastic, Reconstructive, Aesthetic and Hand Surgery, University Hospital Regensburg and Caritas Hospital St. Josef, Regensburg, Germany"},{"name":"Medical Device Lab, Regensburg Center of Biomedical Engineering (RCBE), Faculty of Mechanical Engineering, Ostbayerische Technische Hochschule Regensburg, Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lukas","family":"Prantl","sequence":"additional","affiliation":[{"name":"University Center for Plastic, Reconstructive, Aesthetic and Hand Surgery, University Hospital Regensburg and Caritas Hospital St. Josef, Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vanessa","family":"Tessmann","sequence":"additional","affiliation":[{"name":"University Center for Plastic, Reconstructive, Aesthetic and Hand Surgery, University Hospital Regensburg and Caritas Hospital St. Josef, Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"issue":"2","key":"10.3233\/CH-239101_ref1","doi-asserted-by":"publisher","first-page":"441","DOI":"10.1016\/s0039-6109(16)39388-4","article-title":"Augmentation mammaplasty","volume":"51","author":"Cronin","year":"1971","journal-title":"Surg Clin North Am"},{"issue":"35","key":"10.3233\/CH-239101_ref2","first-page":"427","article-title":"Retromammary prosthesis","volume":"1965","author":"Arion","journal-title":"C R Soc Fr Gynecol"},{"issue":"3","key":"10.3233\/CH-239101_ref3","doi-asserted-by":"publisher","first-page":"220","DOI":"10.1097\/00006534-197209000-00003","article-title":"Clinical trial and evaluation of a proposed new inflatable mammary prosthesis","volume":"50","author":"Regnault","year":"1972","journal-title":"Plast Reconstr Surg"},{"issue":"3","key":"10.3233\/CH-239101_ref4","doi-asserted-by":"publisher","first-page":"681","DOI":"10.1097\/00006534-199909030-00010","article-title":"Radiotransparency of the triglyceride mammary prosthesis: a quantitative analysis with mastectomy specimens,","volume":"104","author":"Garc\u00eda-Tutor","year":"1999","journal-title":"Plast Reconstr Surg"},{"issue":"3","key":"10.3233\/CH-239101_ref5","doi-asserted-by":"publisher","first-page":"1024","DOI":"10.1097\/01.prs.0000105650.09456.86","article-title":"Trilucent breast implants: Voluntary removal following the Medical Device Agency recommendation","volume":"113","author":"Gherardini","year":"2004","journal-title":"Report on 115 consecutive patients.
