Approaches to paraspinal tumours - a technical note.

Neurogenic tumours of the paraspinal space can occur in all age groups. It is common in adult population and relatively rare in elderly group. Usually they are benign, but in children, arising from the autonomic system, tends to be malignant in nature. Usually in adults, they arise from peripheral nerve sheath and are labelled as schwannomas. For a given tumour, determination of a correct surgical approach is mandatory to achieve a successful surgical outcome. Several factors like tumour size, histology, involvement of the bony spinal canal, etc. are some of the deciding factors for a correct surgical approach. Since many such tumours are benign, total excision is possible with a correct surgical approach. If the tumour involves the integrity of the spine then additionally a stabilization procedure may have to be carried out. Unfortunately, there are still no guidelines regarding the choice of surgical approach for the excision of such tumors. Presented here is a series of five patients managed by us over a period of 10 years. Four patients were adults and one female child was three years old. Four patients were operated upon successfully and the fifth one is waiting for surgery.
