ABSTRACT
Objective To explore the effect of neuroendoscopic surgery for the removal of medium and large sized tuberculum sellae meningiomas through supraorbital keyhole approach.Methods A retrospective research was performed on 7 case of patients with tuberculum sellae meningioma who underwent endoscopic surgery through supraorbital keyhole approach.The main performance of patients as tumor diameter were 2.8-4.7 cm and the skin incision located at superciliary aich which size of intra-frontal bone window was 3.5 cm× 2.0 cm.Results Total removal was achieved in 7 cases(simpson Ⅰ grade in 2 patients,sirnpson 1Ⅱ grade in 5 patients).Postoperative,the visual outcomes of eyes were showed improvement in 9 eyes,remained steady in 3 eyes,and deterioration in 2 eyes.All patients were followed up for 6-13 months and no recurrence was found.Conclusion Neuroendoscopic surgery through supraorbital keyhole approach is an effective method for the resection of medium and large sized tuberculum sellae meningiomas.
ABSTRACT
Objective To compare the treatment effect of surgically clipping anterior circulation aneurysms by lateral supraorbital approach and supraorbital keyhole approach for guiding the selection of surgical approach for anterior circulation aneurysms.Methods The clinical data of 80 patients diagnosed as anterior circulation aneurysms due to spontaneous subarachnoid hemorrhage from January 2011 to January 2016 were retrospectively analyzed,including the operation time,craniotomy time,cranial closure time,estimated intraoperative blood loss,HCT change before and after surgery,early ambulation time,postoperative hospitalization days,GCS scores at admission and discharge,GOS scores at discharge were compared between the two groups and the literatures were reviewed.Results The operation time and craniotomy time of the lateral supraorbital approach were less than those of the supraorbital keyhole approach,and the differences between the two groups were statistically significant (P＜0.05);the cranial closure time,estimated intraoperative blood loss,HCT change before and after surgery,early ambulation time,postoperative hospitalization days,GCS scores at admission and discharge and GOS scores at discharge had no statistical differences between the two groups (P＞0.05).Conclusion The lateral supraorbital approach has the advantages of shorter operation time and craniotomy time,providing a better surgical field during operation,less intraoperative traction and less postoperative complications,and can serve as an alternative scheme for the supraorbital keyhole approach in clipping anterior circulation aneurysms.

ABSTRACT
Objective To explore the effect and technical skills of neruoendoscope-assisted microneurosurgery via the supraorbital keyhole apporach for giant olfactory groove meningiomas.Methods A total of 12 patients with giant olfactory groove meningiomas(≥7 cm in diameter)received neruoendoscope-assisted microneurosurgery via the supraorbital keyhole approach.Data of the patients were analyzed retrospectively.Results Among the cases,9 achieved complete resection of the tumor,inlcuding 5 cases of SimpsonⅠ and 4 cases of Simpson Ⅱ.The other 3(Simpson Ⅲ)patients underwent subtotal resection.None of the patients died during the operation.Ten of the patients were follwed up for 3 months to 2 years(mean,14 months).During the follow-up,9 of the 10 resumed physical and sporting activities,and the other one retured to normal daily life.MRI examination was prefomred on 9 patients,none of them had recurrence.Conclusions Neruoendoscope-assisted microneurosurgery via the supraorbital keyhole approach is effective and safe for patient with giant olfactory groove meningioma.The tumor should be removed piece by piece during the operation.
