According to the extension of the disease, EER can be extended to include the anterior skull base (endoscopic resection with transnasal craniectomy; ERTC). The ethmoid roof is exposed using a drill with a diamond burr. The anterior and posterior ethmoidal arteries are identified, cauterized, and divided. The crista galli is carefully detached from the dura and removed with blunt instruments, preserving the integrity of the dural layer.
