Olfactory Groove Meningioma Choice Of Surgical Procedure And Evaluation

Objective to acquire the best therapeutic effect of the olfactory groove meningioma,and compare the selective merit and shortcoming of the operative approach in the different information.Methods review the diagnostic and therapeutic information of the 38 olfactory groove meningioma between the Jan.2003 and the Dec. 2008 in one accessory hospital which belongs to the Medical University of Guangxi.Mainly based on the clinical reflect,and the imageology characteristic,choose the different operational approach,and there is to carry out the compared analysis in the all kinds of therapeutic effect of the all kinds of operative approach,the complication after the operation and the relapse rate.Result According to the Simpson class in all cases of a particular disease the tumors are excisional all.The approach below the forehead is better to improve the patients' olfactory abnormality than the approach at the pterion.The approach at the pterion is better to improve the patients' ocular abnormality than the approach below the forehead.There are averagely small cases in the approach below the forehead and the approach at the pterion,which have the complication of the different degree.There is no difference in the incidence rate and recurrent rate of the two kinds of operational approach complication.Conclusion The approach below the forehead is the classical operative approach of the olfactory groove meningioma,in the clinic which the neurosurgery colleagues favor,and the operative effect is confirmed.Along with the further development in the micrological technology and the promotion of the human requiring the life quality,the approach at the pterion becomes the more predominant operative approach to solve the back superior growth of the olfactory groove meningioma.The way acquires the colleagues' identification.The choice of the operative approach is tightly relative to the tumorous position,size, growing direction,texture and blood supply,etc.
