Here,we investigate the correlation between the newly designed laryngostroboscopy index for unilateral vocal fold paralysis (LSI-UVFP) andan expert group\u2019s rating of voice quality. The LSI UVFP evaluates four key parameters closely related to voice production in UVFPpatients: (1) the vocal fold position, (2) the glottal gap during the closed phase, (3) atrophy of the paralysed vocal fold, and (4) themucosal wave. Each parameter is classified on a four-point ordinal scale: 0 for normal, 1 for mild, 2 for moderate, and 3 for severe. 52video recordings from 26 patients, before and after a voice improving surgery, were evaluated using the LSI-UVFP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The index demonstrates good reliability, with an intra-class correlation coefficient of 0.80. In addition, LSI-UVFP was found to show asignificant correlation with an auditory perceptual rating of voice quality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Thus, rating of laryngostroboscopy by the LSI-UVFP is a valid method for documenting and comparing therapeutic outcomes ininterventional studies for symptomatic UVFP. Its usage enables a meaningful interpretation of videolaryngostroboscopic data withregard to voice quality.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00405-026-10575-4","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T02:35:01Z","timestamp":1789526101000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["An easy-to-use laryngostroboscopy index for unilateral vocal fold paralysis reflects voice quality"],"prefix":"10.1007","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4415-2084","authenticated-orcid":false,"given":"Alexander","family":"Mainka","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-0556-4213","authenticated-orcid":false,"given":"Dirk","family":"M\u00fcrbe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6186-8298","authenticated-orcid":false,"given":"Mario","family":"Fleischer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8103-8542","authenticated-orcid":false,"given":"Tadeus","family":"Nawka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,9,16]]},"reference":[{"issue":"12","key":"10575_CR1","doi-asserted-by":"publisher","first-page":"5459","DOI":"10.1007\/s00405-023-08211-6","volume":"280","author":"JR Lechien","year":"2023","unstructured":"Lechien JR, Geneid A, Bohlender JE, Cantarella G, Avellaneda JC, Desuter G, Sjogren EV, Finck C, Hans S, Hess M, Oguz H, Remacle MJ, Schneider-Stickler B, Tedla M, Schindler A, Vilaseca I, Zabrodsky M, Dikkers FG, Crevier-Buchman L (2023) Consensus for voice quality assessment in clinical practice: guidelines of the european laryngological society and union of the european phoniatricians.
