Adult patients with unexplained cough > ۸wks were included in the study and superior laryngeal nerve block with long acting steroid and local anaesthetic was given. All patients were monitored every two weeks for three months post superior laryngeal nerve block. Pre and post treatment cough severity index (CSI) were compared.Results: In our study of thirty patients, twenty five patients showed subjective symptomatic improvement. Normality of continuous data was assessed using the Shapiro Wilk test. For Intra comparison Paired t-test was used. The mean cough severity index (CSI) score decreased significantly from ۲۴.۵۳۳±۲.۹۰۹ to ۱۶.۱۶۷±۲.۳۶۵ post intervention with p value ۰.۰۰۱ which was found to be highly significant.
