Letter to the Editor. Gamma Knife surgery for trigeminal pain due to benign and malignant skull base tumors

Restricted access

TO THE EDITOR: We have read with great interest the recent article by Phan et al.,5 discussing the role of Gamma Knife surgery (GKS) for trigeminal neuralgia (TN) secondary to recurrent malignant skull base tumors (Phan J, Pollard C III, Brown PD, et al: Stereotactic radiosurgery for trigeminal pain secondary to recurrent malignant skull base tumors. J Neurosurg [epub ahead of print April 27, 2018. DOI: 10.3171/2017.11.JNS172084]). The authors nicely discuss tumor control, symptom palliation, and opioid use/dependency.

The authors’ study highlights several important aspects. First, it underlines the role of single-fraction GKS as
