The repetitive neuromusculoskeletal demands of operatic singing, together with suboptimal technique, intensive training, and psychological strain, may be associated with TMD-related symptoms. Knowledge of TMD and awareness of warning signs may support appropriate health-seeking behaviours. This study aimed to assess self-reported TMD-related symptoms and selected aspects of TMD-related knowledge among Polish opera singers. Methods: An online cross-sectional survey was conducted in 2024 among 241 adult Polish classically trained singers, including professional opera singers and vocal students (90 men and 151 women; age range, 20\u201373 years). Data were collected using an author-developed questionnaire and the Fonseca Anamnestic Index (FAI), a self-report screening instrument for TMD-related symptoms and symptom severity. Results: FAI scores were within the lowest symptom category in 21.6% of participants, within the mild category in 50.6%, within the moderate category in 24.5%, and within the severe category in 3.3%. Overall, 87.1% rated their TMD-related knowledge as poor or sufficient, although 89.6% recognised that TMD may adversely affect vocal technique. Conclusions: Self-reported TMD-related symptoms were frequently observed in this study sample, and responses to individual questionnaire items indicated gaps in selected areas of TMD-related knowledge. A self-reported previous diagnosis of TMD was associated with greater FAI-assessed symptom severity, whereas self-assessed TMD knowledge was not. These findings may support further evaluation of targeted education and access to appropriate clinical assessment for classically trained singers.<\/jats:p>","DOI":"10.3390\/jcm15134980","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T08:43:57Z","timestamp":1782463437000},"page":"4980","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Self-Reported Temporomandibular Disorder Symptoms and Related Knowledge Among Polish Opera Singers"],"prefix":"10.3390","volume":"15","author":[{"given":"Cezary","family":"Roman","sequence":"first","affiliation":[{"name":"Department of Clinical Phonoaudiology and Speech Therapy, Faculty of Health Sciences, Medical University of Bialystok, 15-295 Bialystok, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5116-3497","authenticated-orcid":false,"given":"Mateusz","family":"Cybulski","sequence":"additional","affiliation":[{"name":"Department of Integrated Medical Care, Faculty of Health Sciences, Medical University of Bialystok, 15-096 Bialystok, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7021-2592","authenticated-orcid":false,"given":"Anna","family":"Zalewska","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, Faculty of Health Sciences, University of Lomza, 18-400 Lomza, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1023-3057","authenticated-orcid":false,"given":"Bo\u017cena","family":"Czarkowska-P\u0105czek","sequence":"additional","affiliation":[{"name":"Department of Clinical Nursing, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Marchewka","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, University of Physical Education, 31-571 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5589-4978","authenticated-orcid":false,"given":"Krystyna","family":"Ro\u017cek-Piechura","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy in Internal Medicine and Oncology, University of Health and Sport Sciences, 51-612 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,26]]},"reference":[{"key":"ref_1","first-page":"63","article-title":"Charakterystyka schorze\u0144 staw\u00f3w skroniowo-\u017cuchwowych","volume":"64","author":"Pihut","year":"2016","journal-title":"Dent.
