A therapy for this muscle disorder is the injection of botulinum toxin (BTX), of the LPM. However, there is a potential risk of side effects with the injection guide methods currently available. In addition, they do not permit appropriate differentiation between the two bellies of the muscle. Herein, a novel method is presented to provide intraoral access to the superior head of the human LPM with maximal control and minimal hazards.<jats:italic>Methods.<\/jats:italic>Computational tomography along with digital imaging software programs and rapid prototyping techniques were used to create a rapid prototyped guide to orient BTX injections in the superior LPM.<jats:italic>Results.<\/jats:italic>The method proved to be feasible and reliable. Furthermore, when tested in one volunteer it allowed precise access to the upper head of LPM, without producing side effects.<jats:italic>Conclusions.<\/jats:italic>The prototyped guide presented in this paper is a novel tool that provides intraoral access to the superior head of the LPM. Further studies will be necessary to test the efficacy and validate this method in a larger cohort of subjects.<\/jats:p>","DOI":"10.1155\/2014\/432635","type":"journal-article","created":{"date-parts":[[2014,5,18]],"date-time":"2014-05-18T17:04:53Z","timestamp":1400432693000},"page":"1-8","source":"Crossref","is-referenced-by-count":7,"title":["A Novel Method for Intraoral Access to the Superior Head of the Human Lateral Pterygoid Muscle"],"prefix":"10.1155","volume":"2014","author":[{"given":"Aleli T\u00f4rres","family":"Oliveira","sequence":"first","affiliation":[{"name":"Orofacial Pain and Masticatory Dysfunction Clinic, Dental Clinic Department, School of Dentistry, Federal University of Rio de Janeiro, Avenida Carlos Chagas Filho 373, Centro de Ci\u00eancias da Sa\u00fade, Bloco K, 2\u00b0 Andar, Sala 56, Ilha da Cidade Universit\u00e1ria, 21941-902 Rio de Janeiro, RJ, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anderson Aparecido","family":"Camilo","sequence":"additional","affiliation":[{"name":"Renato Archer Information Technology Center (CTI), Rodovia Dom Pedro I (SP -
