A more targeted iSLN injection approach could provide greater effectiveness. This study prospectively evaluated whether transnasal endoscopic iSLN injections that target the internal iSLN as it transverses the piriform sinuses was effective at treating laryngeal neurosensory disturbances.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This was a prospective cohort analysis performed at a single tertiary care center. Patients with laryngeal neurosensory disturbances underwent transnasal endoscopic iSLN injections bilaterally using triamcinolone-40\u2009mg\/mL. Demographics, clinical history, and exam findings were recorded, along with post-injection complications. The primary outcomes were the Leister Cough Questionnaire (LCQ), Reflux Symptom Index (RSI), and the Voice Handicap Index-10 (VHI-10) collected at pre-injection, 3-weeks post-injection, and 2-months post-injection that were examined with linear mixed modeling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Eighteen patients with laryngeal sensory disturbances (11 with chronic cough and 7 with globus sensation) underwent the procedure.
