1. Objective : To study the effectiveness of transsphenoidal surgery for GH, ACTH, and PRL secreting pituitary adenomas.

2. Conclusions The transsphenoidal microsurgery is optimal treatment in children and adolescents with Cushing's disease.

3. Objective To assess the effect of endonasal transsphenoidal surgery for pituitary adenoma.

4. Conclusion The endoscopic endonasal transsphenoidal approach used in treating ophthalmic aneurysms is credible.

5. Using transsphenoidal microsurgery treated 80 cases of Cushing's disease There were 59 cases of microadenoma, 18 cases of macroadenoma and 3 cases of removed anterior pituitary.

6. They underwent transsphenoidal adenomectomies to remove the TSH - secreting pituitary tumors with excellent results.

7. Surgically, the transsphenoidal approach provides a relatively safe route to the intrasellar meningiomas and satisfactory results.

8. Obliteration of empty sellar by transsphenoidal ap - proach is a simple and effective method.

9. Objective:To search for a safe approach for transsphenoidal endoscopic pituitary surgery, so as to avoid injury of intercavernous sinuses during the operation.

10. Objective To study the methods and the experiences of pituitary adenoma resection via direct monorhinic endonasal transsphenoidal approach.

11. Method: Thirty - two patients with pituitary tumour were treated with endoscopic transsphenoidal surgery.

11.

12. AIM To evaluate the efficacy and safety of nicardipine and urapidil in controlling hypotension and their hemodynamic effects during transsphenoidal pituitectomy.

13. Objective : To study the nursing measures of patients with transsphenoidal microsurgery for pituitary adenoma.

14. Subfrontal approach was chosen in 36 cases, anterior interhemispheric fissure approach in 12, pterional approach in 115, transcallosal approach in 20 and transsphenoidal approach in 3.

15. Objective To explore factors influencing the recurrence of patients with Cushing s disease after transsphenoidal surgery.

16. Method Among the 40 cases with craniopharyngioma, pterion approach was performed in 36 cases, subfrontal approach in 2 cases, and transsphenoidal approach in 2 cases.

17. Methods 5 cases were treated surgically, 3 by subfrontal approach, 2 by transsphenoidal approach.

18. Objective To investigate the methods of prevention and repair of cerebrospinal rhinorrhea by transsphenoidal microsurgical approach.

19. Conclusion BIPSS is helpful in the diagnosis and localization of pediatric and hebetic ACTH pituitary microadenoma, and transsphenoidal surgery is the optimal choice of treatment.

20. Objective To supply anatomic landmarks and parameters for subfrontal transsphenoidal pituitary surgery.

21. Abstact: Objective To summarize the experience in reconstructing the skull base in the sellar and parasellar regions via extended endoscopic endonasal transsphenoidal approach.

22. Objective To study the microanatomy on parasella through an extended transsphenoidal approach and provide morphologic foundation for clinical application.

23. Objective To explore the microsurgical skills and clinical value of endoscope-assisted transsphenoidal approach for middle and lower clival extension of pituitary adenomas.

24. Conclusions Preoperative bromocriptine treatment did not affect the outcome of transsphenoidal microsurgery in female patients with prolactinomas.
