    Abstract:
    OBJECT: To improve results of surgical treatment of ventral and ventrolateral tumors of the spinal cord, the authors analyzed surgical approaches, defined the indications for various approaches, and assessed the clinical results. METHODS: Between 1993 and 2004 the authors treated 360 patients: 43 of them had dorsal, 177 dorsolateral, 33 ventral, and 107 had ventrolateral intradural extramedullary tumors. Among 140 patients with intradural extramedullary ventral and ventrolateral tumors, neuromas were seen in 56 and meningiomas in 84. Of the 140 patients studied, tumors were removed totally in 102 (74%), subtotally in 30 (21%), and partially in eight (5%). After ventrolateral and dorsolateral approaches were introduced in 1996, tumors in ventral or ventrolateral locations have been removed totally or subtotally. In the group of patients with meningiomas, 41 of the lesions were the meningothelial type, 22 were transitional, 12 fibroblastic, four psammomatous, three were angiomatous, one was atypical, and one was malignant. Tumors in the neuroma group were schwannomas in 45 patients and neurofibromas in 11. Postoperatively, recovery was observed in 70 patients (50%), improvement in 53 (38%), no change in 10 (7%), and deterioration in seven (5%). At follow-up evaluation recovery was noted in 76 patients, improvement in 58, no change in four, and in two patients the neurological symptoms were worse than before the operation. CONCLUSIONS: Surgical routes to extramedullary tumors should be chosen based on the location of the tumor, its spread, and the region in which it is localized.
