Figure 1 Case 1—Lower lip entrapment in a motorized electric nail trimmer in a 4-year-old girl and subsequent repair.(A) The device attached to the lower lip in the emergency department, with the lip drawn into the aperture on the underside of the device. The battery had already been disconnected, and a handheld rotary cutting tool (left) was applied to the outer casing away from the entrapped tissue; the surrounding face was protected by gauze. (B) The same device after the casing had been opened, showing the exposed battery and circuit board; the internal wheels were then manually rotated to release the lip. (C) The lower lip immediately after release, showing a deep, jagged, full-thickness laceration with tissue loss. (D) The same lip after irrigation and primary closure with 5-0 absorbable sutures under local infiltration anesthesia. All images were obtained during the index emergency department visit.
