Polymethylmethacrylate filler complications, despite being rare, are often permanent and difficult or even impossible to treat. Safety guidelines should be observed when considering use of polymethylmethacrylate for augmentation.
Background: In advanced head and neck tumors margins are very rarely comprehensively checked by frozen sections. The goal of this study was to analyze a new proposal for harvesting margins using a double-bladed scalpel.Methods:Thirty-eight patients underwent a comprehensive resection of advanced head and neck tumors with a double-bladed scalpel. Margins were mapped and checked by frozen sections, while tumor resection continued. When positive margins were identified, they were excised again, and checked by frozen sections. Results: Thirty-three patients (87%) had clear skin and soft tissue margins at frozen sections. Five patients (13%) had focal skin and soft tissue-positive margins at frozen sections, which were re-excised. Two patients (5%) had skin and soft tissue-positive margins only at permanent sections. One was reoperated and 1 received radiation therapy. The 3-year local control rate was 58%. Conclusions: In this preliminary study, the double-bladed scalpel appeared to be an interesting option for complete intraoperative evaluation of surgical margins of advanced head and neck tumors.
The vertical suture of the rectus abdominis sheaths was stronger than the horizontal suture because of the more transversal arrangement of its aponeurotic fibers. Thus, routine use of the vertical suture in plications of the aponeurosis of the rectus abdominis muscles is suggested.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
