Ultra large craniotomy and window implantation

(A) The dorsal skull is thinned along the edges of the cranial window and the suture lines. The skull needs to be thinned until the underlying vasculature pattern becomes clearly visible as shown in the zoomed image.

(B) The split bones will be removed in the ascending order from #1 to #4. Grab the bone with forceps and slowly slide it toward the arrow direction on the image.

(C) After removal of the bones. Dura is kept intact.

(D) A glass plug is pressed on the cortex, and the position is fixed with 3M Vetbond and Krazy glue.

(E) After the glass implantation.
