Lack of prenatal symptom and a typical clinical presentation lead to failure to arrive at a correct diagnosis and confusion during resuscitation. We report a case of a newborn male child with type 2 tracheal agenesis. Despite a typical presentation, diagnosis was delayed after unsuccessful intubation, examination under anaesthesia and emergency tracheostomy. The embryology, diagnostic criteria and potential treatment options are discussed. This case report is valuable in increasing awareness of this rare condition and will help us in being better prepared in managing these children. Future studies should aim to find the optimal replacement for the tracheal.<\/jats:p>","DOI":"10.1136\/bcr-2017-224003","type":"journal-article","created":{"date-parts":[[2019,7,15]],"date-time":"2019-07-15T13:22:18Z","timestamp":1563196938000},"page":"bcr-2017-224003","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Tracheal agenesis in a new born: lessons learnt"],"prefix":"10.1136","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2547-7230","authenticated-orcid":false,"given":"P","family":"Naina","sequence":"first","affiliation":[{"name":"Department of ENT, Christian Medical College and Hospital Vellore, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary","family":"John","sequence":"additional","affiliation":[{"name":"Department of ENT, Christian Medical College and Hospital Vellore, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed Abdul","family":"Kathar","sequence":"additional","affiliation":[{"name":"Department of ENT, Christian Medical College and Hospital Vellore, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manish","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Neonatology, Christian Medical College, Vellore, Tamilnadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,6,17]]},"reference":[{"key":"2025082702312138000_2018.jun16_1.bcr-2017-224003.1","doi-asserted-by":"crossref","first-page":"425","DOI":"10.1007\/s00431-011-1563-x","article-title":"Tracheal agenesis: approach towards this severe diagnosis.
