This manuscript reports the case of a 30-year-old Caucasian with a knife blade lodged in the maxillofacial skeleton. Following clinical and radiographic exams, it was determined that the object had penetrated through the left nostril and nasal septum, in the direction of the right maxillary sinus, and remained impacted without causing injury to important anatomical structures. After systemic assessment and determination of the exact location of the knife blade, the object was removed in an outpatient setting under local anaesthesia. This manuscript aims to report a rare case of a transfacial penetrating injury involving a knife blade that was removed in an outpatient setting while also discussing the proper conduct and treatment options for similar cases in the context of a brief literature review.<\/jats:p>","DOI":"10.1136\/bcr-2013-008839","type":"journal-article","created":{"date-parts":[[2013,4,11]],"date-time":"2013-04-11T05:58:19Z","timestamp":1365659899000},"page":"bcr-2013-008839","source":"Crossref","is-referenced-by-count":5,"title":["Jael syndrome: removal of a knife blade impacted in the maxillofacial region under local anaesthesia"],"prefix":"10.1136","volume":"2013","author":[{"given":"Paulo Roberto","family":"Dominguete","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruno Figueiredo","family":"Matos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tufi Neder","family":"Meyer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucinei Roberto","family":"Oliveira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,4,10]]},"reference":[{"key":"2025042707160983000_2013.apr10_1.bcr-2013-008839.1","first-page":"55","article-title":"Penetrating stab wound injuries to the face","volume":"2013","author":"Daya","year":"2004","journal-title":"SADJ"},{"key":"2025042707160983000_2013.apr10_1.bcr-2013-008839.2","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1007\/s10006-009-0144-x","article-title":"Migration of tip knife blade through middle-third facial tissues","volume":"2013","author":"Chrcanovic","year":"2009","journal-title":"Oral Maxillofac Surg"},{"key":"2025042707160983000_2013.apr10_1.bcr-2013-008839.3","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1016\/j.injury.2009.05.003","article-title":"Knife inflicted penetrating injuries of the maxillofacial region: a descriptive record-based study","volume":"2013","author":"Meer","year":"2010","journal-title":"Injury"},{"key":"2025042707160983000_2013.apr10_1.bcr-2013-008839.4","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1016\/0278-2391(86)90108-4","article-title":"Penetrating injuries to the maxillofacial region","volume":"2013","author":"Cohen","year":"1986","journal-title":"J Oral Maxillofac Surg"},{"key":"2025042707160983000_2013.apr10_1.bcr-2013-008839.5","doi-asserted-by":"crossref","first-page":"51","DOI":"10.1097\/00063110-200103000-00010","article-title":"Injury caused by deeply penetrating knife blade lodged in infratemporal fossa","volume":"2013","author":"Cosan","year":"2001","journal-title":"Eur J Emerg Med"},{"key":"2025042707160983000_2013.apr10_1.bcr-2013-008839.6","doi-asserted-by":"crossref","first-page":"1221","DOI":"10.1053\/joms.2001.26730","article-title":"Impacted knife injuries in the maxillofacial region: report of 2 cases","volume":"2013","author":"Shinohara","year":"2001","journal-title":"J Oral Maxillofac Surg"},{"key":"2025042707160983000_2013.apr10_1.bcr-2013-008839.7","doi-asserted-by":"crossref","first-page":"258","DOI":"10.1016\/0266-4356(86)90090-2","article-title":"A severe craniofacial impalement injury (Jael's syndrome)","volume":"2013","author":"Mckechnie","year":"1986","journal-title":"Br J Oral Maxillofac Surg"},{"key":"2025042707160983000_2013.apr10_1.bcr-2013-008839.8","doi-asserted-by":"crossref","first-page":"1404","DOI":"10.1097\/SCS.0b013e31821cc53e","article-title":"Impacted foreign bodies in the maxillofacial region-diagnosis and treatment","volume":"2013","author":"Santos Tde","year":"2011","journal-title":"J Craniofac Surg"},{"key":"2025042707160983000_2013.apr10_1.bcr-2013-008839.9","doi-asserted-by":"crossref","first-page":"60","DOI":"10.1016\/S1010-5182(88)80019-2","article-title":"Deliberately inflicted penetrating injuries of the maxillofacial region (Jael's syndrome).
