Traditional techniques for removing stuck backings involve forceful manipulation, resulting in pain, scarring, and suboptimal cosmetic outcomes.</p></div><div><h3>Discussion</h3><p>In this technique description, we present an alternative atraumatic technique for the removal of stuck ear-piercing backings. The technique involves injecting a mixture of local anesthetic and a vasoconstrictor, around the backing to create a fluid pocket that loosens the earring post. A special maneuver is then applied using a needle driver allowing for easy gentle removal. If the backing remains embedded, gentle pressure on the earlobe reveals a loop that can be threaded with a syringe needle to propel the backing out.</p></div><div><h3>Conclusions</h3><p>The proposed atraumatic technique for removing stuck ear-piercing backings offers a satisfactory and less stressful experience for pediatric patients while reducing the need for emergency department referrals. Given the lack of consensus on extraction methods, this technique provides a valuable alternative in the absence of a widely agreed-upon approach. Further research is needed to establish standardized protocols. Nevertheless, adopting this technique has the potential to enhance patient satisfaction and improve outcomes.</p></div>","PeriodicalId":73546,"journal":{"name":"JEM reports","volume":"3 2","pages":"Article 100091"},"PeriodicalIF":0.0,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S277323202400021X/pdfft?md5=c09da96c1cc33eddfa73b391fa97d56f&pid=1-s2.0-S277323202400021X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140820148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
