Complications decrease with advanced technology. Studies confirm its efficacy in acromegaly treatment.
Historical Development of the Surgery
Pioneers developed transsphenoidal hypophysectomy in the early 1900s. Harvey Cushing refined the technique initially. He performed it on numerous patients successfully. Microscopes improved precision in the 1960s. Endoscopes revolutionized access in the 1990s. Modern navigation systems enhance safety now. Surgeons adapt it for various tumor sizes. Historical data shows reduced mortality rates. Innovations continue to minimize risks. Global adoption increases yearly.
Anatomical Considerations
The pituitary sits in the sella turcica. Sphenoid bone houses this structure securely. Nasal passages provide direct entry points. Surgeons navigate through the ethmoid cells. Optic nerves lie adjacent to the gland. Carotid arteries border the surgical field. Precise dissection prevents vascular injuries. Bone removal exposes the dura mater. Tumor resection follows careful planning. Postoperative imaging verifies complete removal.
Indications for Transsphenoidal Hypophysectomy
Doctors indicate this for pituitary adenomas. It treats prolactinomas resistant to medication. Cushing’s syndrome patients undergo it often. Acromegaly cases benefit from growth hormone reduction. Non-functioning tumors require excision too. Craniopharyngiomas sometimes necessitate this approach. Rathke’s cleft cysts get drained effectively. Hypopituitarism correction follows tumor removal. Invasive adenomas demand aggressive resection. Pediatric cases adapt the technique safely.
Hormonal Imbalances Addressed
Excess cortisol production prompts surgical intervention. Prolactin elevation causes infertility issues. Growth hormone oversecretion leads to gigantism. ACTH-secreting tumors disrupt metabolism.
