Plain skull X-ray revealed an extensive retained blade with subsequent CT imaging revealing the tip of the blade had reached the right styloid process with no neurovascular compromise. Initial concern was primarily for the left eye leading to ophthalmology being the first specialty requested to review the patient. However, once the extent of the injury was established, ophthalmology requested further review from maxillofacial, ENT and neurosurgery. This resulted in an 84\u2009hours wait between the initial injury and the removal of the knife blade. Incredibly, the patient had no initial sequelae from such an extensive injury and had an unremarkable recovery with no further complications aside from a laceration to the left inferior rectus muscle that was conservatively managed.<\/jats:p>","DOI":"10.1136\/bcr-2018-226054","type":"journal-article","created":{"date-parts":[[2018,9,23]],"date-time":"2018-09-23T23:54:26Z","timestamp":1537746866000},"page":"bcr-2018-226054","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["On a knife-edge: clinical uncertainty with an extensive knife blade in situ in the craniofacial region"],"prefix":"10.1136","volume":"2018","author":[{"given":"Dairui","family":"Dai","sequence":"first","affiliation":[{"name":"Department of Medicine, University College London Medical School, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silke","family":"Meyer","sequence":"additional","affiliation":[{"name":"Department of Medicine, Universitatsmedizin Greifswald, Greifswald, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars Christian","family":"Kaltheuner","sequence":"additional","affiliation":[{"name":"Department of Medicine, Universitatsmedizin Greifswald, Greifswald, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Plani","sequence":"additional","affiliation":[{"name":"Trauma Department, Chris Hani Baragwanath Hospital, Johannesburg, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2018,9,23]]},"reference":[{"key":"2025082801343125000_2018.sep22_1.bcr-2018-226054.1","doi-asserted-by":"crossref","first-page":"512","DOI":"10.3171\/jns.1997.87.4.0512","article-title":"Patients with retained transcranial knife blades: a high-risk group","volume":"87","author":"Taylor","year":"1997","journal-title":"J Neurosurg"},{"key":"2025082801343125000_2018.sep22_1.bcr-2018-226054.2","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/650916"},{"key":"2025082801343125000_2018.sep22_1.bcr-2018-226054.3","doi-asserted-by":"crossref","first-page":"bcr-2013-008839","DOI":"10.1136\/bcr-2013-008839","article-title":"Jael syndrome: removal of a knife blade impacted in the maxillofacial region under local anaesthesia","volume":"2013","author":"Dominguete","year":"2013","journal-title":"BMJ Case Rep"},{"key":"2025082801343125000_2018.sep22_1.bcr-2018-226054.4","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-199211000-00012"},{"key":"2025082801343125000_2018.sep22_1.bcr-2018-226054.5","doi-asserted-by":"crossref","first-page":"356","DOI":"10.1055\/s-0035-1546813","article-title":"Penetrating Orbital-Cranial Injuries Management in a Limited Resource Hospital in Latin America","volume":"8","author":"Estebanez","year":"2015","journal-title":"Craniomaxillofac Trauma Reconstr"},{"key":"2025082801343125000_2018.sep22_1.bcr-2018-226054.6","doi-asserted-by":"publisher","DOI":"10.1136\/emj.2004.021923"},{"key":"2025082801343125000_2018.sep22_1.bcr-2018-226054.7","doi-asserted-by":"crossref","first-page":"e41","DOI":"10.1308\/147870810X12699662981672","article-title":"Penetrating knife injury to the frontal lobe--a case report","volume":"92","author":"Gulati","year":"2010","journal-title":"Ann R Coll Surg Engl"},{"key":"2025082801343125000_2018.sep22_1.bcr-2018-226054.8","doi-asserted-by":"publisher","DOI":"10.1016\/S0379-0738(02)00271-2"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2018-226054","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T08:34:38Z","timestamp":1756370078000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2018-226054"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,23]]},"references-count":8,"alternative-id":["10.1136\/bcr-2018-226054"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2018-226054","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,9,23]]}}}
