Iatrogenic asymmetry is a recognized complication of botulinum toxin injections and may cause both functional and emotional distress. Contralateral botulinum toxin adjustment is an accepted corrective strategy, but few case reports have documented its use for toxin-induced asymmetry with photographic evidence. A 44-year-old woman developed facial asymmetry after cosmetic botulinum toxin injections. She presented with upward deviation of the left oral commissure and midface both at rest and during speech, causing psychosocial discomfort. Dynamic assessment showed relative overactivity of the left facial muscles compared with the weakened right side. Targeted contralateral injections of botulinum toxin type A were delivered into the left zygomaticus minor, depressor anguli oris, and mentalis muscles (14 units). At the 2-week follow-up, the patient showed substantial restoration of facial balance with improved commissure position and symmetry. Posttreatment photographs confirmed correction. No adverse events were observed. Contralateral botulinum toxin injection is a possible minimally invasive method for correcting toxin-induced asymmetry.<\/jats:p>\n                  <jats:p>Level of Evidence: 5 (Therapeutic) \u00a0<\/jats:p>","DOI":"10.1093\/asjof\/ojag051","type":"journal-article","created":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T13:00:10Z","timestamp":1773838810000},"source":"Crossref","is-referenced-by-count":1,"title":["Correction of Iatrogenic Facial Asymmetry Caused by Botulinum Toxin Using Contralateral Injection: A Case Report"],"prefix":"10.1093","volume":"8","author":[{"given":"Muhammad Rayyan","family":"Bilal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rana Hassan","family":"Javaid","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Afsheen","family":"Bilal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,3,20]]},"reference":[{"key":"2026041703424361900_ojag051-B1","doi-asserted-by":"publisher","first-page":"1638","DOI":"10.1098\/rstb.2010.0404","article-title":"Facial attractiveness: evolutionary based research","volume":"366","author":"Little","year":"2011","journal-title":"Philos Trans R Soc Lond B Biol Sci"},{"key":"2026041703424361900_ojag051-B2","doi-asserted-by":"publisher","first-page":"659","DOI":"10.3758\/BF03208842","article-title":"Facial symmetry and the perception of beauty","volume":"5","author":"Rhodes","year":"1998","journal-title":"Psychon Bull Rev"},{"key":"2026041703424361900_ojag051-B3","doi-asserted-by":"publisher","first-page":"e137","DOI":"10.1097\/mao.0b013e31827c9f58","article-title":"Contralateral botulinum toxin injection to improve facial asymmetry after acute facial paralysis","volume":"66","author":"Kim","year":"2013","journal-title":"J Plast Reconstr Aesthet Surg"},{"key":"2026041703424361900_ojag051-B4","doi-asserted-by":"publisher","first-page":"e131","DOI":"10.1016\/j.bjps.2013.04.012","article-title":"Botulinum toxin injection of both sides of the face to treat post-paralytic facial synkinesis","volume":"66","author":"Choi","year":"2013","journal-title":"J Plast Reconstr Aesthet Surg"},{"key":"2026041703424361900_ojag051-B5","doi-asserted-by":"publisher","first-page":"417","DOI":"10.1055\/s-0039-3401987","article-title":"The treatment of facial asymmetry with botulinum toxin: current concepts, guidelines, and future trends","volume":"36","author":"Heydenrych","year":"2020","journal-title":"Facial Plast Surg"},{"key":"2026041703424361900_ojag051-B6","doi-asserted-by":"publisher","first-page":"833","DOI":"10.1016\/j.bjps.2017.01.009","article-title":"Botulinum toxin treatment for facial palsy: a systematic review","volume":"70","author":"Cooper","year":"2017","journal-title":"J Plast Reconstr Aesthet Surg"},{"key":"2026041703424361900_ojag051-B7","doi-asserted-by":"publisher","first-page":"1431","DOI":"10.1038\/eye.2012.189","article-title":"Botulinum toxin to improve lower facial symmetry in facial palsy","volume":"26","author":"Sadiq","year":"2012","journal-title":"Eye (Lond)"},{"key":"2026041703424361900_ojag051-B8","doi-asserted-by":"publisher","first-page":"456","DOI":"10.3390\/toxins12070456","article-title":"Effect of botulinum toxin injection on asymmetric lower facial contour","volume":"12","author":"Kim","year":"2020","journal-title":"Toxins (Basel)"}],"container-title":["Aesthetic Surgery Journal Open Forum"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/asjopenforum\/advance-article-pdf\/doi\/10.1093\/asjof\/ojag051\/67424271\/ojag051.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/asjopenforum\/article-pdf\/doi\/10.1093\/asjof\/ojag051\/68100106\/ojag051.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/asjopenforum\/article-pdf\/doi\/10.1093\/asjof\/ojag051\/68100106\/ojag051.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,17]],"date-time":"2026-04-17T07:42:49Z","timestamp":1776411769000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/asjopenforum\/article\/doi\/10.1093\/asjof\/ojag051\/8529767"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":8,"URL":"https:\/\/doi.org\/10.1093\/asjof\/ojag051","relation":{},"ISSN":["2631-4797"],"issn-type":[{"value":"2631-4797","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026]]},"published":{"date-parts":[[2026]]},"article-number":"ojag051"}}
