Usefulness of transcervical approach for surgical treatment of hypoglossal schwannoma with paraspinal extension: case report.
BACKGROUND
Usefulness of transcervical approach to hypoglossal schwannoma with paraspinal extension is described herein.


METHODS
A 54-year-old woman presented with gradually worsening left hypoglossal nerve palsy. The findings were of a tumor lying in the left hypoglossal canal and paraspinal region and were consistent with hypoglossal schwannoma. Subtotal intracapsular removal of the tumor was performed via transcervical approach. The symptoms improved, and no additional symptoms were noted.


CONCLUSIONS
The transcervical approach and intracapsular removal of the tumor under electrophysiological monitoring provided for successful minimally invasive surgery in this case of hypoglossal schwannoma.
