Fetal laryngoscopy enables direct airway endoluminal visualization of the airway, thereby complementing prenatal imaging to enhance diagnosis and counseling. In this case, CHAOS was diagnosed at 17\u2009weeks of gestation following ultrasound and fetal magnetic resonance imaging, which revealed tracheal dilation and echogenic lungs. Diagnostic fetal laryngoscopy performed at 24\u2009weeks demonstrated a blind\u2010ended trachea that was not amenable to fetal decompression. Despite counseling regarding the limited feasibility of airway establishment, emergent delivery with an ex utero intrapartum treatment (EXIT) procedure was performed at 30\u2009weeks. Airway establishment was unsuccessful, and the neonate died shortly after birth. Significant maternal hemorrhage occurred after delivery, requiring transfusion. This case underscores the complexity of prenatal counseling and family\u2010centered decision\u2010making. Fetal laryngoscopy may be considered an adjunct to improve diagnostic evaluation and counseling, potentially aiding prenatal decision\u2010making in selected cases of CHAOS.<\/jats:p>","DOI":"10.1111\/jog.70383","type":"journal-article","created":{"date-parts":[[2026,6,30]],"date-time":"2026-06-30T00:34:47Z","timestamp":1782779687000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Role
