Translation, validation and cross\u2010cultural adaptation were carried out according to generally accepted methodology. Validation study of the Lithuanian version of NLDO\u2010SS (L\u2010NLDO\u2010SS) was performed, and short\u2010 and long\u2010term results of EN\u2010DCRS procedure were evaluated according to symptoms. In total, 44 patients were evaluated 2\u00a0weeks before the surgical intervention, a day before the surgery and 41 patients 2\u00a0months after the surgery, and again 10\u00a0months later.<\/jats:p><\/jats:sec><jats:sec><jats:title>Main outcome measures<\/jats:title><jats:p>We analysed the internal consistency and test\u2010retest reliability of the L\u2010NLDO\u2010SS questionnaire. Cronbach's alpha was used to represent and evaluate internal consistency for ordinal responses. Validity was assessed by comparing scores between a control group of volunteers without NLDO and the NLDO group using Mann\u2010Whitney test. To test the limiting score on which the sensitivity and specificity curves cross in identifying patients with NLDO, receiver operating characteristic (ROC) curve analysis was used. The pre\u2010 and post\u2010operative scores were compared using the paired t\u2010test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results showed an acceptable internal consistency of L\u2010NLDO\u2010SS questionnaire, with Cronbach's alpha\u2014.73 in the initial test group and .71 in the retest group. Pearson's correlation coefficient was .94 (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001), revealing good correlation between the initial scores and the retest scores. Our sample of healthy individuals had a mean L\u2010NLDO\u2010SS score of 11.42 (\u00b112.69) points, and patients being scheduled for EN\u2010DCRS had a mean L\u2010NLDO\u2010SS score of 27.45 (\u00b19.81) points. Post\u2010operatively mean L\u2010NLDO\u2010SS scores improved from 27.45 (\u00b19.81) points to 4.45 (\u00b16.29) points in the short term and to 5.83 (\u00b14.17) in the long term, demonstrating the statistically significant responsiveness of the instrument over both timescales.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Lithuanian version of NLDO\u2010SS questionnaire is a valid instrument for assessing patients with NLDO in the Lithuanian population.
