However, the Open Quotient remained lower than pre-surgery levels at the 3-week follow-up, indicating a lasting change in glottal function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Vocal fold oscillation recovers relatively quickly after blue light laser treatment, generally returning to baseline within 24\u2009hours.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Relevance<\/jats:title>\n                    <jats:p>This study highlights the temporary nature of vocal fold impairments following blue light laser surgery, providing insights for patient recovery expectations and voice rest recommendations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Trial<\/jats:title>\n                    <jats:p>\n                      German Clinical Trials Register, number DRKS00035411\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/www.drks.de\/DRKS00035411\">https:\/\/www.drks.de\/DRKS00035411<\/jats:ext-link>\n                      .\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/19160216251409743","type":"journal-article","created":{"date-parts":[[2026,1,24]],"date-time":"2026-01-24T04:07:56Z","timestamp":1769227676000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Vocal Folds\u2019 Oscillatory Characteristics After Photoangiolytic Laser Treatment Using the Blue Light Laser\u2014A Pilot Study"],"prefix":"10.1177","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0095-5360","authenticated-orcid":false,"given":"Matthias","family":"Echternach","sequence":"first","affiliation":[{"name":"Division Phoniatrics and Pediatric Audiology, Department of Otolaryngology, Munich University Hospital and Faculty of Medicine (LMU Munich), Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"D\u00f6llinger","sequence":"additional","affiliation":[{"name":"Division of Phoniatrics and Pediatric Audiology, Department of Otolaryngology Head &amp; Neck Surgery, University Hospital Erlangen, Friedrich-Alexander-University Erlangen-N\u00fcrnberg, Erlangen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1497-559X","authenticated-orcid":false,"given":"Bernhard","family":"Richter","sequence":"additional","affiliation":[{"name":"Freiburg Institute for Musicians\u2018 Medicine, University of Music Freiburg, Medical Center and Faculty of Medicine \u2013 University of Freiburg, Freiburg Centre for Music Research and Teaching, Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5827-0781","authenticated-orcid":false,"given":"Marie","family":"K\u00f6berlein","sequence":"additional","affiliation":[{"name":"Division Phoniatrics and Pediatric Audiology, Department of Otolaryngology, Munich University Hospital and Faculty of Medicine (LMU Munich), Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,1,23]]},"reference":[{"key":"e_1_3_3_2_2","volume-title":"The Science of the Singing Voice","author":"Sundberg J.","year":"1987","unstructured":"Sundberg J.
