Penetrating injuries, especially those involving the palate intraoral region, often occur in children. This is because when children begin to walk, their range of action increases but is unstable; moreover, children frequently play with something stuck in their mouth. Penetrating injuries of the facial region are rare. Many patients recover without brain trauma. We report a case of a penetrating injury of the facial region. A 4-year old girl fell down, and a pair of tweezers penetrated her left cheek and temple. The tweezers was used to feed tropical fish. She was taken to the emergency room without removal of the tweezers. Her consciousness was clear, but she had impaired movement of the left eye and a left-side nosebleed. After a radiographic examination, the tweezers were removed under a local anesthesia. The deep penetration caused cerebrospinal fluid leakage. The bleeding volume was small. The wound was compressed after being sutured. A computed tomographic scan showed no brain injury. Antibiotics were prescribed for several days. As of 22 months after injury, there have been no complications and the outcome is good.
