1. Orbit pterion approach is favorable for exposing aneurysms.

2. Objective:To investigate the feasibility of pterion approach with microsurgery treatment of the anterior circulation aneurysm.

3. Methods: The pterion and the region around it were observed and measured, and the data treated statistically.

4. Methods: Adopting through the pterion the temporal lobe and frontal lobe were divided with vessels protected, then the tumors were removed piece by piece under the microscopy.

5. 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.

6. Methods:The approach via pterion was adopted to treat ICA with clipping of aneurysm. 7 cases of ICA were treated and 10 cases of aneurysm were clipped.

7. Objective:To approach the forte and effects of pterion -temple association approach decompression procedure.

8. Conclusion :The pterion approach is a very useful surgical approach for treatment of anterior circulation aneurysms on the basis of c...

9. A direct blow to the pterion, or even an indirect blow to another part of the skull, may cause a fracture to this weak area, with an associated rupture of the underlying vessel.

10. Objective To investigate the clinical effect of big bone flap craniotomy of partial recovery frontal bone flap and pterion point big bone flap decompression in the therapy of frontal lobe contusion.

11. Objective To analyze the efficacy, reasonability and results of treatment of severe craniocerebral injury on frontal and tempus with enlarged pterion approach and resection of tempus muscle.

12. Objective To evaluate the clinical outcome of microsurgical excision of large sellar region tumors via supra-orbital small craniotomy through pterion al incision.

13. Methods 49 cases of subacute pituitary apoplexy (27 males and 22 females) underwent resection of pituitary adenoma via subfrontal approach, pterion approach, nasal-sphenoidal approach respectively.

13. is a sentence dictionary, on which you can find good sentences for a large number of words.

14. Methods Of the 15 cases of craniopharyngioma, 12 cases underwent total removal and 3 cases received subtotal resection, all through pterion under general anesthesia.

15. Objective To investigate the effect of decompression of optical canal via pterion approach for traumatic optic nerve injury.

16. Conclusion: It is a feasible and effective method to remove the insular tumors through the pterion.

17. Objective:To study the clinical value of the fifth interspace (internal carotid artery upper interspace) by pterion approach for removing sellar tumor.

18. Objective:To sum up the experience of microsurgical removal of the insular tumors through the pterion.

19. The operative approaches included supraorbital keyhole approach in 38, post-mastoidal in 19, pterion in 5, and temporal in 11.
