Objective: Spinal tumours are mostly benign, having devastating effects on patients in terms of patient’s dis-ability, morbidity and mortality. Depending upon their site, size and growth potential, they have different clinical effects on the patients. We are presenting a case series of 138 patients managed in neurosurgery department Mayo hospital from Nov 2011 to Sept 2014.metastatic bony spinal lesions were not included in this study . The objectives of my study are to determine: Types of spinal tumours treated in this setting. Common and differenti-ating clinical features among subjects, different locations of the same types and the role of microsurgery. Materials and Methods: It is a retrospective study. 55 Schawanomas, 34 Menengiomas, 15 Ependimomas, 06 Dermoids, 17 Astrocytomas, 07 Plasmacytomas, 02 Aneurysm bone cyst and 02 Teratomas were managed surgi-cally. Schwanoma and meningioma’s prevalence was more in cervical and dorsal areas. plasmacytomas mainly affected dorsal spine, astrocytomas and ependymomas hade different locations. Teratomas occupied conus medu-llaris. Multiple laminectomies and laminotomies were performed according to situation. Radical resections for intradural extramedullary and gross total debulking for intramedullary lesions, under high resolution Microscope was done. Post operative improvements and complications were noted. Results: A radical resection of these tumors results in a good long-term outcome, since the majority is histolo-gically benign. For intradural intramedullary tumours gross total debulking is more appropriate. Adjuvant radi-ation therapy should only be administered for the high grade or malignant tumor. Malignant tumors have a dismal outcome and surgery in these patients should be a conservative debulking. Open door laminotomies are preferable in intradural extramedulary lesions and does not cause post op spinal deformity. Conclusion: Radical surgery for spinal tumors with laminotomies gives good results in terms of patient’s func-tionality and spinal stability.
