Modification of the Cushing speculum used for transsphenoidal pituitary surgery. Technical note.
A modification of the original Cushing speculum used in the sublabial-transseptal-transsphenoidal approach to the pituitary is described. Although the modified speculum has smaller dimensions, it allows better visualization of the surgical field, while a new expanding device permits easier opening of the speculum.
