After performing multiple unconditional logistic regression analyses, significant risk factors associated with the microtia group included maternal history of miscarriage\/stillbirth (adjusted odds ratio [AOR]\u2009=\u20094.74-4.96), diabetes (AOR\u2009=\u20096.46), hypertension (AOR\u2009=\u20094.18), maternal smoking (AOR\u2009=\u20092.06), paternal smoking (AOR\u2009=\u20092.42-2.83), lack of TORCH vaccination (AOR\u2009=\u20091.59-2.02), and family history (AOR\u2009=\u20095.36), all with\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      value\u2009&lt;\u2009.05.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Microtia in Indonesia reflects global patterns, with male predominance and right-sided unilateral cases. Associated risk factors include parental smoking, maternal comorbidities, lack of TORCH vaccination, and genetic predisposition. Public health strategies should promote smoking cessation, prenatal care, and vaccination. Further studies should ensure matching between the control and microtia groups, minimize recall bias, and explore genetic links.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10556656251378594","type":"journal-article","created":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T04:52:56Z","timestamp":1758603176000},"page":"2421-2429","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Analytical Study of Microtia Risk Factors in Indonesia"],"prefix":"10.1177","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2578-808X","authenticated-orcid":false,"given":"Jilvientasia Godive","family":"Lilihata","sequence":"first","affiliation":[{"name":"Airlangga University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7209-6206","authenticated-orcid":false,"given":"Imaniar Fitri","family":"Aisyah","sequence":"additional","affiliation":[{"name":"Institut Teknologi Sepuluh Nopember"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-1062-1297","authenticated-orcid":false,"given":"Magda Rosalina","family":"Hutagalung","sequence":"additional","affiliation":[{"name":"Airlangga University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4725-4676","authenticated-orcid":false,"given":"Pudji","family":"Lestari","sequence":"additional","affiliation":[{"name":"Airlangga University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6668-6496","authenticated-orcid":false,"given":"Indri Lakhsmi","family":"Putri","sequence":"additional","affiliation":[{"name":"Airlangga University"},{"name":"Plastic Reconstructive and Aesthetic Surgery Unit, Airlangga University Hospital, Surabaya, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,9,22]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-35683-4"},{"key":"e_1_3_4_3_2","unstructured":"Lin SJ.
