The aim of this study was to evaluate functional results of medialization thyroplasty using a hydroxyapatite implant (VoCoM).<\/jats:p><jats:p><jats:bold>Study Design<\/jats:bold>: Prospective observational cohort study.<\/jats:p><jats:p><jats:bold>Methods<\/jats:bold>: Between 1999 and 2003, a total of 26 patients (19 men, 7 women) undergoing medialization thyroplasty using a hydroxyapatite implant because of unilateral vocal fold paralysis were enrolled in the study. To evaluate voice function, the following parameters were measured preoperatively and postoperatively: mean fundamental frequency, mean sound pressure level, frequency and amplitude range (voice range profile), and maximum phonation time. A perceptual assessment of hoarseness was conducted using the Roughness, Breathiness, Hoarseness scale. Furthermore, the magnitude of voice related impairment of the patient's communication skills was rated on a 7\u2010point scale. A combined parameter called the Voice Dysfunction Index (VDI) was used to rate vocal performance.<\/jats:p><jats:p><jats:bold>Results<\/jats:bold>: All patients showed a statistically significant improvement in the VDI, in perceptual voice analysis, in maximum phonation time, and in the dynamic range of voice. One patient experienced a postoperative wound hemorrhage as a minor complication. No further complications or implant extrusions were observed.<\/jats:p><jats:p><jats:bold>Conclusions<\/jats:bold>: Medialization thyroplasty using a hydroxyapatite implant is a secure and efficient phonosurgical procedure. Voice quality and patient satisfaction improve significantly after treatment.<\/jats:p>","DOI":"10.1097\/mlg.0b013e318041f6ed","type":"journal-article","created":{"date-parts":[[2007,4,5]],"date-time":"2007-04-05T08:05:12Z","timestamp":1175760312000},"page":"1118-1122","source":"Crossref","is-referenced-by-count":31,"title":["Functional Outcome of Vocal Fold Medialization Thyroplasty With a Hydroxyapatite Implant"],"prefix":"10.1002","volume":"117","author":[{"given":"Claudio","family":"Storck","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meike","family":"Brockmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elvira","family":"Schnellmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandro J.","family":"Stoeckli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Schmid","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,1,2]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"1265","article-title":"Plastik am Schildknorpel zur Behebung der Folgen einseitiger Stimmbandl\u00e4hmung.","volume":"43","author":"Payr E","year":"1915","journal-title":"Dtsch med Wschr"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.3109\/00016487409126379"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s004050000299"},{"key":"e_1_2_6_5_2","first-page":"305","article-title":"Empfehlung der UEP: Standardisierung Stimmfeldmessung\/Phonetographie.","volume":"7","author":"Seidner W","year":"1982","journal-title":"HNO Praxis"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-996925"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1080\/000164800750000748"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199812000-00001"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348949910800112"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200304000-00008"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1067\/mhn.2000.102574"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlg.0000168059.12949.a6"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200108000-00003"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199305000-00008"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1010-7940(02)00839-4"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348949610500303"}],"container-title":["The Laryngoscope"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1097%2FMLG.0b013e318041f6ed","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1097\/MLG.0b013e318041f6ed","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,10]],"date-time":"2023-10-10T02:42:07Z","timestamp":1696905727000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1097\/MLG.0b013e318041f6ed"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,6]]},"references-count":15,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2007,6]]}},"alternative-id":["10.1097\/MLG.0b013e318041f6ed"],"URL":"https:\/\/doi.org\/10.1097\/mlg.0b013e318041f6ed","archive":["Portico"],"relation":{},"ISSN":["0023-852X","1531-4995"],"issn-type":[{"value":"0023-852X","type":"print"},{"value":"1531-4995","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,6]]}}}
