Abstract

To evaluate the overall therapeutic effectiveness of transsphenoidal microsurgery for pituitary adenomas and explore the surgical technique, application of new technology, and postoperative follow-up. The clinical presentation, imaging features, endocrine examination, pathological types, conditions of operation, postoperative complications, and follow-up of 4050 patients with pituitary adenomas who had undergone transsphenoidal microsurgery from December 1981 to January 2004 were analyzed retrospectively. During the past 6 years, total tumor resection (under microscope) has been achieved in 97.3% of the patients with Hardy Grade I adenomas, 95.2% of Hardy Grade II, 90.4% of Hardy Grade III, and 47.4% of Hardy Grade IV. The percentages of total and subtotal resection achieved extended from 87.6% before 1987 to 96.9% in 2003. With the improvement of microsurgical technique and application of novel technology, the indications for transsphenoidal microsurgery for pituitary adenomas were increasingly extended. We believe that more than 90% of pituitary adenomas could be treated by the transsphenoidal approach and totally removed through the microscope. The transnasal perpendicular plate-sphenoid sinus approach will be the dominant m...Continue Reading

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
