TO THE READERSHIP: An error appeared in the article by Kim et al. (Kim TY, Jackson CM, Xia Y, et al: Retrosigmoid approach for glycerin rhizotomy in the treatment of trigeminal neuralgia without overt arterial compression: updated case series. J Neurosurg [epub ahead of print March 8, 2019; DOI: 10.3171/2018.12.JNS182572]).
Due to a production error, the legend for Fig. 1 was not updated in the online ahead-of-print article prior to its publication. The figure appears here with the correct legend.
Kaplan-Meier pain recurrence rate in patients who experienced pain recurrence after MVD only and MVD+glycerin injection treatment. No statistical significance was found (p = 0.08). Figure is available in color online only.
We apologize to the authors for this oversight. The article has been corrected online as of March 29, 2019.
