On physical examination, the patient had a violet-coloured, tense swelling of the left soft palate with uvular deviation, without active bleeding. Nasopharyngolaryngoscopy revealed a bulging of the pharyngeal walls up to the level of the epiglottis, with preserved laryngeal mobility. These findings were compatible with a large expanding post-extraction haematoma and prompted emergent orotracheal intubation in the operating room under visualisation with video laryngoscope for airway protection and surgical exploration for haemostasis. The progressive reabsorption of the haematoma allowed for the patient to be extubated after 5 days and after 1\u2009month he experienced a near full recovery. This case alerts physicians, particularly otolaryngologists for the possibility of life-threatening vascular complications following molar extractions.<\/jats:p>","DOI":"10.1136\/bcr-2024-262785","type":"journal-article","created":{"date-parts":[[2025,7,25]],"date-time":"2025-07-25T09:25:22Z","timestamp":1753435522000},"page":"e262785","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Acute cervical haematoma after tooth extraction: an emergent and life-threatening complication"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8117-5528","authenticated-orcid":false,"given":"Paulo","family":"Pina","sequence":"first","affiliation":[{"name":"Otorhinolaryngology, Vila Nova de Gaia Espinho Hospital Center, Vila Nova de Gaia, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00f3nica","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Vila Nova de Gaia Espinho Hospital Center, Vila Nova de Gaia, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edite","family":"Coimbra","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Vila Nova de Gaia Espinho Hospital Center, Vila Nova de Gaia, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4040-6585","authenticated-orcid":false,"given":"Pedro","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Vila Nova de Gaia Espinho Hospital Center, Vila Nova de Gaia, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,7,25]]},"reference":[{"key":"2025082713013581000_18.7.e262785.1","doi-asserted-by":"crossref","first-page":"75","DOI":"10.17219\/dmp\/127028","article-title":"Analysis of complications after the removal of 339 third molars","volume":"58","author":"Kienca\u0142o","year":"2021","journal-title":"Dent Med Probl"},{"key":"2025082713013581000_18.7.e262785.2","doi-asserted-by":"crossref","first-page":"e230","DOI":"10.18295\/squmj.2019.19.03.009","article-title":"Complications of Third Molar Extraction: A retrospective study from a tertiary healthcare centre in Oman","volume":"19","author":"Sayed","year":"2019","journal-title":"Sultan Qaboos Univ Med J"},{"key":"2025082713013581000_18.7.e262785.3","first-page":"670","article-title":"Life-threatening hemorrhage after extraction of third molars:case report and management protocol","volume":"68","author":"Moghadam","year":"2002","journal-title":"J Can Dent Assoc"},{"key":"2025082713013581000_18.7.e262785.4","doi-asserted-by":"crossref","DOI":"10.1093\/jscr\/rjad082","article-title":"Airway emergency after dental extraction","volume":"2023","author":"Cheng","year":"2023","journal-title":"J Surg Case Rep"},{"key":"2025082713013581000_18.7.e262785.5","doi-asserted-by":"crossref","first-page":"855","DOI":"10.1016\/0278-2391(86)90221-1","article-title":"Complications following removal of impacted third molars: the role of the experience of the surgeon","volume":"44","author":"Sisk","year":"1986","journal-title":"J Oral Maxillofac Surg"},{"key":"2025082713013581000_18.7.e262785.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2003.04.001"},{"key":"2025082713013581000_18.7.e262785.7","doi-asserted-by":"crossref","unstructured":"Roberts G , Scully C , Shotts R .
