Migration of tip knife blade through middle-third facial tissues.
OBJECTIVE
The aim of this paper is to report a case of knife aggression with a spontaneous migration of a tip blade lodged in deep tissues 6 months after trauma.


METHODS
An 18-year-old woman that was a victim of impalement injury with a knife by her boyfriend on the glabella region with a blade fracture and tip lodging into middle-third facial tissues.


RESULTS
After conservative management of a knife tip, a spontaneous migration occurred with its exposition on the zygomatic area, possibly due to a functional treatment to improve mouth opening.


CONCLUSIONS
Fracture of knife blade with a tip retained deeply into the tissues is considered foreign body, and its removal must be considered. Nevertheless, the basis for this removal takes account the cost-benefit ratio, and if a conservative management was chosen, the clinical and radiological accompanying is mandatory to prevent and to treat its possible complications.
