GTR is associated with better [[QoL]] using the general QoL measures [[SF-36]] and [[PROMIS]]-10 and the disease-specific [[PANQOL]], even after controlling for baseline and outcome differences. This is especially significant in the assessment of mental health, indicating there may indeed be a psychological advantage to the patient that translates to overall well-being to have the entire tumor removed if microsurgical [[resection]] is undertaken ((Link MJ, Lund-Johansen M, Lohse CM, Driscoll CLW, Myrseth E, Tveiten OV, Carlson ML.
