The depth and extension of the excision were graded according to the European Laryngological Society Classification including 5 types of cordectomy. All patients were subsequently examined every 2 months for a period ranging from 30 to 66 months (mean, 48 months). The rates of 5-year overall survival, disease-free survival, ultimate local control with laser alone, and laryngeal preservation were 85%, 87%, 93%, and 95%, respectively. Sixty-nine patients underwent, at least 1 year after surgery, videolaryngostroboscopy combined with perceptual and objective evaluation of the voice, and spirometry. Acoustic parameters were compared with those obtained in a matched control group by Kruskal-Wallis test. No statistically significant difference was found (p &gt; .05) between patients submitted to subepithelial (type I) and subligamental (type II) cordectomies and controls.\n                  <\/jats:p>","DOI":"10.1177\/000348940311200212","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:40:52Z","timestamp":1412347252000},"page":"174-179","source":"Crossref","is-referenced-by-count":74,"title":["Vocal Outcome after Endoscopic Cordectomies for Tis and T1 Glottic Carcinomas"],"prefix":"10.1177","volume":"112","author":[{"given":"Giorgio","family":"Peretti","sequence":"first","affiliation":[{"name":"Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cesare","family":"Piazza","sequence":"additional","affiliation":[{"name":"Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanna","family":"Cantarella","sequence":"additional","affiliation":[{"name":"Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristiano","family":"Balzanelli","sequence":"additional","affiliation":[{"name":"Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piero","family":"Nicolai","sequence":"additional","affiliation":[{"name":"Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2003,2,1]]},"reference":[{"key":"bibr1-000348940311200212","doi-asserted-by":"crossref","unstructured":"Hirano M, Hirade Y.
