Ultrasound is increasingly used in dermatology, along with the guidance of mini\u2010invasive procedures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aims<\/jats:title><jats:p>To evaluate the role of ultrasound for guiding the application of Botulinum A toxin in patients with cosmetic alterations due to bruxism, correlate the clinical landmarks with the ultrasound findings, and study the effect on the symptoms, cosmetics, and quality of life.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients\/Methods<\/jats:title><jats:p>Twenty individuals with bruxism and cosmetic alterations underwent an ultrasound\u2010guided injection of Botulinum toxin type A in each masseter muscle. Clinical and ultrasound marking of the procedure was compared. Clinical and sonographic evaluation was performed at the time of injection and 3 months later. Ten normal individuals underwent ultrasound of the masseter muscles as a control group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Up to 65% of individuals showed anatomical variants of the salivary glands. The method for clinically marking the skin showed a frequently erroneous location of the anterior point (up to 40% of cases) that was proven by ultrasound to be out of the muscle. In 20% of cases, ultrasound showed that the needle should be longer to enter the muscle. After injection, most of the patients demonstrated a decrease of the symptoms and cosmetic and quality of life improvements.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Ultrasound can be a potent tool for guiding the injection of Botulinum toxin into the masseter muscles. It may contribute to a more personalized procedure, better cosmetic results, and help to avoid potential complications.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jocd.12208","type":"journal-article","created":{"date-parts":[[2016,1,22]],"date-time":"2016-01-22T14:01:26Z","timestamp":1453471286000},"page":"238-244","source":"Crossref","is-referenced-by-count":34,"title":["Comparison of clinical marking and ultrasound\u2010guided injection of Botulinum type A toxin into the masseter muscles for treating bruxism and its cosmetic effects"],"prefix":"10.1111","volume":"15","author":[{"given":"Natacha","family":"Quezada\u2010Gaon","sequence":"first","affiliation":[{"name":"Department of Dermatology Faculty of Medicine Pontifical Catholic University Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ximena","family":"Wortsman","sequence":"additional","affiliation":[{"name":"Department of Radiology and Department of Dermatology Institute for Diagnostic Imaging and Research of the Skin and Soft Tissues Clinica Servet Faculty of Medicine University of Chile Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osvaldo","family":"Pe\u00f1aloza","sequence":"additional","affiliation":[{"name":"Department of Dentistry University Pedro de Valdivia Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Eduardo","family":"Carrasco","sequence":"additional","affiliation":[{"name":"Department of Dermatology Faculty of Medicine Pontifical Catholic University Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,1,22]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"135","volume-title":"Aesthetic Dermatology: Botulinum Toxin","author":"Goodman G","year":"2013"},{"key":"e_1_2_6_3_1","first-page":"79","volume-title":"Toxina Botul\u00ednica: Concep\u00e7\u00e3o de Beleza e da Est\u00e9tica Atual","author":"Tamura B","year":"2007"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-1331.2006.01441.x"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.37.4.616"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.52.5.652"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-200102000-00004"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1524-4725.2003.29117.x"},{"key":"e_1_2_6_9_1","first-page":"223","volume-title":"Topographic Anatomy","author":"Testut L","year":"1981"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1067\/moe.2001.111760"},{"key":"e_1_2_6_11_1","first-page":"878","article-title":"Avaliacao do remodelamento do terco inferior da face ap\u00f3s tratamento da hipertrofia do masseter con toxina botul\u00ednica tipo A","volume":"89","author":"Soza\u2010Klein FHM","year":"2014","journal-title":"An Bras Dermatol"},{"key":"e_1_2_6_12_1","first-page":"185","volume-title":"Cosmetic Use of Botulinum Toxin","author":"Trinidad de Almeida A","year":"2002"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.2012.31.1.97"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.asj.2008.03.003"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1590\/1678-775720130694"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.13286"}],"container-title":["Journal of Cosmetic Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjocd.12208","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjocd.12208","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jocd.12208","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,1]],"date-time":"2023-10-01T09:44:15Z","timestamp":1696153455000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/jocd.12208"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,1,22]]},"references-count":15,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2016,9]]}},"alternative-id":["10.1111\/jocd.12208"],"URL":"https:\/\/doi.org\/10.1111\/jocd.12208","archive":["Portico"],"relation":{},"ISSN":["1473-2130","1473-2165"],"issn-type":[{"value":"1473-2130","type":"print"},{"value":"1473-2165","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,1,22]]}}}
