Simpson CB, et al. - Authors presented their outcomes for the treatment of neurogenic cough with localized blockade of the internal branch of the superior laryngeal nerve (SLN). They recorded and analyzed the patient demographics, indications for injection, and response to treatment. Results demonstrated that the patients had undergone an average of 2.4 SLN block procedures. Afer injection, mean follow-up time was 85.4 days. For neurogenic cough, the SLN block was an effective treatment, with average cough severity index (CSI) scores significantly improved following injection.
