Abstract

BACKGROUND:

Surgical treatment of extramedullary craniovertebral and upper cervical tumors differs essentially, depending on the peculiarities of their localization.

MATERIALS AND METHODS:

In the Spinal Department of the Institute of Neurosurgery during the period from 2000 to 2010, 96 patients with ventral and ventrolateral intradural extramedullary craniovertebral tumors and tumors of upper cervical localization were examined and operated.

RESULTS:

The patients were distributed as follows. Tumors of the craniovertebral localization: These are neoplasms spreading in rostral direction up to the boundary of the lower third of the clivus and in caudal direction up to the upper edge body of the axis (C0-C1) - 12 patients; tumors at the C1-C2 level: 28 patients; and tumors at the C1-C2-C3 level: 56 patients. The tumors were divided into ventral (60) and ventrolateral (36).

CONCLUSION:

Therefore, the adequate choice of a surgical approach first depends on the localization of the tumor, its size and the extent to which it has spread. In most cases of extramedullary ventrolateral tumors of craniovertebral and upper cervical localization, far lateral and posterolateral approaches are the most optimum and the least traumatic. The extreme lateral approach is advisable in cases of big size ventral craniovertebral tumors.

KEYWORDS:

Extreme lateral approach; far lateral; ventral tumor; ventrolateral tumor
