Superior laryngeal nerve block for neurogenic cough: A case series

Abstract

Objectives: To demonstrate that an in-office superior laryngeal nerve (SLN) block with lidocaine and steroids is an effective alternative to neuromodulators for patients with neurogenic cough. Study Design: Retrospective study. Methods: A retrospective review of 10 patients who underwent in office nerve block to the laryngeal nerve (SLN) for neurogenic cough. Demographic data and pre- and postcough survey index are the measure outcomes. Follow-up was 3–6 months. Results: We find that all patients in this study that underwent an SLN block showed significant improvement in cough severity index (CSI). The average number of blocks was 2.3. The mean follow-up time from the first SLN block is 3.4 months. The mean CSI improvement 16.30. 95% confidence interval, 11.44–21.16; P
