Study Of Convex Meningioma Endocranium's Invasion

Objective:To discuss convex meningioma endocranium's invasion degree, by its drafts, the dropsy around meningioma , the tumor pathology minute with the meninx tail, the immunity group's relevance, plans to determine in the technique the endocranium best excision scope.Methods:Selections convexes meningioma Simpson 1 level excises 27 examples, in the technique excises nearby the lump in 3cm the endocramium, and stochastically extracts 0.5, 1.0, 1.5, 2.0, 2.5, the 3cm good pathological section inspection, simultaneously if the image study material, the tumor pathology corresponding change compares, and carries on statistics analysis.Result:In 27 examples meningiomas patient 7 examples pathology prompt tumor corrosion lump Zhou Yingmo, accounts for 25,9%, in 0.5cm is corroded 6 examples (6/27,22.22%);In 1cm is made a sneak invasion 5 examples (5/27,18.52%);In 1.5cm endocramium 3 examples (3/27,11.11%);In 2cm 1 example;In 2.5cm 1 example (1/27,3.7%) The endocramium is corroded the group with not to corrode in the group and the lump week dropsy, the lump the low density stove has significance the difference, if the degree presents the correlation;But with the tumor spot, the size, the pathology rank and the endocramium tail drafts and the immunity group not obvious relevance.Conclusion:Convex meninx surgery Simpson 1 level of excisions at the same time, should excise at least 2.1cm the endocramium and the accumulation arachnoid, regarding the lump memory in the low density stove and obvious dropsy should be excised mostly, reduces recurrence rate.
