Safety of a simple asymmetric jaw technique in the treatment of head and neck cancer.
We reviewed our experience treating head and neck malignancies junctioning over the spinal cord using asymmetric collimation. The mean dose delivered to the cord was 43.28 Gy above to the junction, 40.36 Gy below it. With a median follow-up of 20 months, none of our 32 patients developed radiation myelitis.
