We present the case of a 46-year-old man who was involved in a motor vehicle accident in which his forehead struck the dashboard of his semi-tractor trailer. A toggle switch penetrated the anterior and posterior tables of his frontal sinus and lodged in the frontal lobe. The foreign body was not found on physical examination at an emergency care facility. The wound was closed, and the patient was sent home. Severe headaches prompted his return the next day. Skull roentgenograms showed the toggle switch, and the patient was referred to our institution for definitive care. This unusual case serves to emphasize the potential for a foreign body to penetrate the frontal sinus with few physical findings.
