Deng Z, et al. - Researchers sought to examine delayed relief (DR) and its predictors after microvascular decompression (MVD) and/or partial sensory rhizotomy (PSR) which is the most effective surgical treatment for trigeminal neuralgia (TN). In addition, they studied the long-term effects linked with DR. They defined DR as follows: no differences in the Barrow Neurological Institute (BNI) score on the third day following surgery and a BNI score of I-II in the absence of any medication after a period of pain. They performed follow-up for at least 1 year after the operation of 105 patients who underwent MVD and/or PSR for TN by the same surgeon at the China-Japan Friendship Hospital from March 2009 to December 2017. The patients included 20 patients with DR (19%), 78 patients with non-DR (74%), and 7 patients without relief. The DR group had postoperative pain duration of 3–365 days, with an average of 108 days. Outcomes revealed no long-term effects of DR after MVD and/or PSR. Hence they recommend monitoring patients for approximately 3 months after MVD and/or PSR and then evaluating for surgical effects. No immediate reoperations should be undertaken.
