The first choice is to make a surgical incision to remove the glass slag. If the glass slag is superficial and its shape can be felt in the epidermis, it can be removed by making an incision after local anesthesia is given, but if the glass slag is inserted deeper and can’t be felt in the epidermis, local X-ray can be taken, and the Plexiglas or toughened glass can be visualized under the X-ray, and can be localized according to the photograph. Plexiglass or tempered glass can be visualized under X-ray film, and can be localized according to the photo so as to cut and take it out. If the glass residue is very small and broken, it can’t be taken out by surgical method, and can only be left inside the flesh, waiting for local inflammation and pus, after pus, the glass residue is in the middle of the pus spot, and the glass residue can be discharged by incision and drainage of pus.
