Inclusion criteria included a history consistent with neurogenic cough and age\u2009\u2265\u200918. Exclusion criteria included patients with untreated other etiologies of chronic cough (i.e., uncontrolled reflux) and current neuromodulating medication use. Patients were randomized into the treatment (1\u20132\u2009mL of a 1:1 triamcinolone 40\u2009mg: 1% lidocaine with 1:200,000 epinephrines) or placebo (saline) group and received two unilateral injections at approximately 2\u2010week intervals. Outcomes were measured primarily by the Leicester Cough Questionnaire (LCQ) and a patient symptom log including a visual analog scale of cough severity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>17 patients completed the study, including 10 in the treatment group and seven in the placebo group. Eight (80%) patients in the treatment group reported improvement with at least one of the injections, whereas only 1 (14.3%) patient reported improvement in the placebo group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001). Average total LCQ scores increased in the treatment group from 10.09 to 13.15 (<jats:italic>p<\/jats:italic>\u2009=\u20090.03), with the most change occurring in the social domain. There was no statistically significant change in LCQ scores for the placebo group.
