Sklar's Cushing-Landolt speculum is a hand held, duck billed neurological instrument used to remove tumors of the pituitary region - adenomas, craniopharyngiomas, biopsies and debulking of large tumors. The Cusing-Landolt is for transphenoidal entry, rather then an open craniotomy. This product is available in three different blade sizes. Teh blades of the Cushing-Landolt have a greater curve than the Hardy and Papavero-Caspar in this same product class.
