Foramen magnum area, upper cervical area, glomus jugulare area are sugical complex area. We have treated 15 Foramen magnum area, upper cervical area, glomus jugulare area tumors.
We assess the effect of the Gamma knife radiosurgery for upper cervical area.
We have treated 15 patients with Gamma-plan during the last 14 years .The 15 patients were comprised of five men and ten women, their ages ranging from 25 to 77 years(mean age:51 years). The histologic diagnoses are 4 glomus jugulare tumor, 2 cervicomedullary hemangioblastomas, 3 meningiomas,3 astrocytomas, 1 hemangioma, 1 ependymoma, 1 hypoglossal tumor.
Preradiosurgical surgical intervention was performed in 4. Mean maximal dose was 21.6 Gy Mean marginal dose was 10.8 Gy.
Mean follow up period is 41 months (19-108 months).
This is a retrospective study.
Gamma Knife radiosurgery is very effective for upper cervical tumor, foramen magnum tumor, glomus jugulare tumor patients without neurological deficit or minimal deficit.
Further clinical experience is warranted. Project Roles:
