transsphenoidal การใช้

Pituitary radiation therapy is another option for treatment of postoperative persisting hypercortisolemia following unsuccessful transsphenoidal surgery.
The transsphenoidal and intracranial approaches to pituitary tumors began in the 1800s but with little success.
On March 16, 1907 Schloffer performed the first transsphenoidal surgery for removal of a pituitary adenoma at the University of Innsbruck.
Transsphenoidal surgery ( removal of the tumor by an operation through the nose and the sphenoidal sinuses ) may, apart from addressing symptoms related to the tumor, also improve pituitary function, although the gland is sometimes damaged further as a result of the surgery.
For that reason, says Dr . Beverly M . K . Biller, an endocrinologist at Massachusetts General Hospital, it is crucial to find a neurosurgeon who has done " hundreds and hundreds " of the surgeries, usually a procedure called a transsphenoidal adenomectomy, in which the tumor is removed through the nose or an opening below the upper lip.
