RT Journal Article SR Electronic T1 Sino-orbital foreign body caused by a slingshot injury in a young boy JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e251214 DO 10.1136/bcr-2022-251214 VO 15 IS 9 A1 Kenneth Lai A1 Juliet Laycock A1 Adam Bates A1 Julian Hamann YR 2022 UL http://casereports.bmj.com/content/15/9/e251214.abstract AB Slingshots or hand catapults, historically used as a military or hunting weapon, are common toys among children and young teenagers. Their use can be dangerous as a strike to the eye or orbit can result in significant injuries including blindness. We describe a rare case of a sino-orbital foreign body caused by a slingshot injury in a young boy. The case was managed by a multidisciplinary team involving ear, nose and throat, ophthalmology and paediatrics, and the foreign body of a metal ball bearing was removed using an endoscopic transnasal approach. Although the patient made a good recovery, the case highlights the danger of slingshot devices misused by children.
