Short forceps were used in 60 (61.2\u202f%), vacuum extraction in 25 (25.5\u202f%), and breech extraction in 13 (13.3\u202f%) births. Transcutaneous bilirubin levels at 48\u202fh of life did not differ significantly between extraction techniques. Phototherapy was required in 8.3\u202f% of neonates following forceps, in 20.0\u202f% following vacuum, and in none following breech extraction; these differences were not statistically significant. After adjustment for surgeon experience, the use of forceps or vacuum was not independently associated with transcutaneous bilirubin levels or phototherapy requirement. In contrast, procedures performed by highly experienced obstetricians were associated with a significantly lower likelihood of phototherapy requirement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_jpm-2026-0181_abs_004\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In cesarean births complicated by difficult fetal extraction of an unengaged fetal head, neonatal bilirubin levels and phototherapy requirement were not associated with extraction technique but were associated with surgeon experience.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1515\/jpm-2026-0181","type":"journal-article","created":{"date-parts":[[2026,5,22]],"date-time":"2026-05-22T11:02:46Z","timestamp":1779447766000},"page":"1029-1035","source":"Crossref","is-referenced-by-count":0,"title":["Forceps, vacuum, and breech extraction for difficult delivery of an unengaged fetal head during cesarean birth: a retrospective cohort study"],"prefix":"10.1515","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8013-4732","authenticated-orcid":false,"given":"Marcos Javier","family":"Cuerva","sequence":"first","affiliation":[{"name":"Department of Obstetrics , Hospital Universitario La Paz , Madrid , Spain"},{"name":"Departamento de Obstetricia y Ginecolog\u00eda, Facultad de Medicina , Universidad Aut\u00f3noma de Madrid , Madrid , Spain"},{"name":"Facultad de Ciencias Biom\u00e9dicas y de la Salud , Universidad Alfonso X el Sabio (UAX) , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beatriz","family":"Garcia","sequence":"additional","affiliation":[{"name":"Departamento de Obstetricia y Ginecolog\u00eda, Facultad de Medicina , Universidad Aut\u00f3noma de Madrid , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alicia","family":"Ramirez-Castan","sequence":"additional","affiliation":[{"name":"Department of Obstetrics , Hospital Universitario La Paz , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Defarges","sequence":"additional","affiliation":[{"name":"Department of Obstetrics , Hospital Universitario La Paz , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta","family":"Cortes","sequence":"additional","affiliation":[{"name":"Department of Obstetrics , Hospital Universitario La Paz , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Lopez-Magallon","sequence":"additional","affiliation":[{"name":"Department of Obstetrics , Hospital Universitario La Paz , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos","family":"Zozaya","sequence":"additional","affiliation":[{"name":"Department of Neonatology, Pediatrics , Hospital Universitario La Paz , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisco","family":"Lopez","sequence":"additional","affiliation":[{"name":"Department of Obstetrics , Hospital Universitario La Paz , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Luis","family":"Bartha","sequence":"additional","affiliation":[{"name":"Department of Obstetrics , Hospital Universitario La Paz , Madrid , Spain"},{"name":"Departamento de Obstetricia y Ginecolog\u00eda, Facultad de Medicina , Universidad Aut\u00f3noma de Madrid , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2026,5,25]]},"reference":[{"key":"2026070714574614356_j_jpm-2026-0181_ref_001","doi-asserted-by":"crossref","unstructured":"Ammitzb\u00f8ll, ILA, Andersen, BR, Lange, KHW, Clausen, T, L\u00f8kkegaard, ECL.
