Figure 1: Simple Line diagrams showing a transverse cut section at the level of tumor prior to laminectomy (a) displaying lamina (1), duramater (2), arachnoidal layer (3), epipial/pial layer (4) & intra-medullary tumor (5); after the laminectomy is performed (b). A midline durotomy is performed and dural edges are help apart using stay suture. (c) Our novel modification of the pial stay suturing technique with enmasse suturing of the dura, arachnoid & epipial/pial layers. It results in a wider exposure of the tumor with better visualization angle (d)
