Most patients achieve smoother, less effortful voicing with standard injection regimens. However, there is a notable failure rate. We performed fine-wire electromyography on 214 consecutive patients with laryngeal dystonia. We correlated voice ratings, stroboscopy data, and fine-wire electromyography data. Videostroboscopy was successful in visually demonstrating most of the audible findings in isolated vocal tremor, but it was much less successful in identifying breaks alone or a combination of breaks and tremor. Fine-wire electromyography revealed that the thyroarytenoid muscle was significantly more likely than the lateral cricoarytenoid muscle to be the predominant muscle associated with adductor spasmodic dysphonia, and that the thyroarytenoid and lateral cricoarytenoid muscles were equally likely to be predominantly involved in tremor spasmodic dysphonia. In addition, several patients in both the adductor spasmodic dysphonia and the tremor spasmodic dysphonia groups presented with interarytenoid muscle predominance. All of the intrinsic laryngeal muscles are capable of being the predominant muscle in laryngeal dystonia, and there are patterns of muscle abnormalities that differ between adductor spasmodic dysphonia and tremor spasmodic dysphonia. Some of the failures in treating adductor spasmodic dysphonia with botulinum toxin, and the greater difficulty with success in treating patients with tremor spasmodic dysphonia, are due to failure to deliver toxin to the appropriate muscles.<\/jats:p>","DOI":"10.1177\/000348940411300802","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:40:52Z","timestamp":1412347252000},"page":"602-612","source":"Crossref","is-referenced-by-count":40,"title":["Findings of Multiple Muscle Involvement in a Study of 214 Patients with Laryngeal Dystonia Using Fine-Wire Electromyography"],"prefix":"10.1177","volume":"113","author":[{"given":"Darrell A.","family":"Klotz","sequence":"first","affiliation":[{"name":"Charlotte, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ariana","family":"Shahinfar","sequence":"additional","affiliation":[{"name":"Charlotte, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicole C.","family":"Maronian","sequence":"additional","affiliation":[{"name":"Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lawrence","family":"Robinson","sequence":"additional","affiliation":[{"name":"Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia F.","family":"Waugh","sequence":"additional","affiliation":[{"name":"Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allen D.","family":"Hillel","sequence":"additional","affiliation":[{"name":"Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2004,8,1]]},"reference":[{"key":"bibr1-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1177\/000348949110000201"},{"key":"bibr2-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1177\/000348948509400614"},{"key":"bibr3-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.124.4.476"},{"key":"bibr4-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198802000-00015"},{"key":"bibr5-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1016\/S0892-1997(05)80168-7"},{"key":"bibr6-000348940411300802","first-page":"5","volume-title":"Spasmodic dysphonia: State of the art 1984","author":"Freeman FJ","year":"1985"},{"key":"bibr7-000348940411300802","first-page":"1","volume-title":"The visible voice","volume":"1","author":"Koufman JA","year":"1992"},{"key":"bibr8-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199810000-00003"},{"key":"bibr9-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1016\/S0892-1997(05)80347-9"},{"key":"bibr10-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199202000-00011"},{"key":"bibr11-000348940411300802","first-page":"187","volume-title":"Clinical voice disorders","author":"Aronson A","year":"1985"},{"key":"bibr12-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1177\/019459989010300515"},{"key":"bibr13-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198301000-00002"},{"key":"bibr14-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198301000-00001"},{"key":"bibr15-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199204000-00006"},{"key":"bibr16-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1990.03450200079035"},{"key":"bibr17-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-089445-1.50028-X"},{"key":"bibr18-000348940411300802","doi-asserted-by":"crossref","first-page":"630","DOI":"10.1288\/00005537-199106000-00010","volume":"101","author":"Troung DD","year":"1991","journal-title":"Laryngoscope"},{"key":"bibr19-000348940411300802","doi-asserted-by":"publisher","DOI":"10.1177\/000348940010900906"},{"key":"bibr20-000348940411300802","doi-asserted-by":"publisher","DOI":"10.3109\/13682829809179445"},{"key":"bibr21-000348940411300802","first-page":"8","volume":"9","author":"American Academy of Otolaryngology-Head and Neck Surgery Policy Statement","year":"1990","journal-title":"In: Bulletin: AAO-HNS Bulletin"},{"key":"bibr22-000348940411300802","unstructured":"National Institutes of Health Consensus Development Conference Consensus Statement.
