A fully retained knife blade within the face
Penetrating knife injuries to the face are uncommon, even rarer are impacted knife blades. Published in the Oral and Maxillofacial Surgery Cases, the authors present the case of a 25 year old gentleman admitted with a penetrating knife injury to the orbit and a 10.6cm retained blade.

Management included multidisciplinary evaluation of the patient, radiological assessment of bony and vascular injury, and removal of the blade under general anaesthetic. Despite such a gruesome injury, all visual parameters were fully restored on discharge.

Removal of the retained knife blade was performed under general anaesthetic jointly with ophthalmology. The existing laceration was used for access and upon retraction the blade was visualised.

A bony window was produced within the infraorbital rim periosteum in order to better visualise and access the blade. The blade was extracted in the opposite direction of entry. Heavy artery forceps were attached to the knife blade and a mallet was used to uneventfully tap it out of the maxillofacial skeleton.
