OBJECTIVE: To determine the effect of injection augmentation of the vocal folds on chronic cough symptoms in patients with glottic insufficiency.
METHODS: Medical records from 146 consecutive patients who underwent vocal fold injection augmentation by a fellowship-trained laryngologist between 2013 and 2015 were reviewed. Twenty-three patients (12 male) met inclusion criteria of a vocal fold augmentation injection, cough symptoms lasting more than 8 weeks, and glottic insufficiency as determined by shortened closed phase on stroboscopy. Exclusion criteria included lack of cough complaints, diagnosis of vocal fold immobility, previous history of vocal fold augmentation, and incomplete data sets. Data collected included age, gender, pre- and 1-month postinjection Cough Severity Index (CSI) scores, location of injection (unilateral or bilateral), and patient statement of percent change in symptoms that was recorded at 1-month postinjection visit.
RESULTS: Paired t test indicated a significant decrease in CSI scores from pre- (m = 18.5) to 1-month postinjection (m = 12.1) (P = 0.004). Eighteen patients (78.2%) reported a 50% or greater improvement in cough symptoms at the 1-month postinjection visit.
CONCLUSION: Injection augmentation of the vocal folds in the presence of glottic insufficiency appears to improve cough symptoms, as was reported by CSI in patients who are refractory to other medical and behavioral treatments.
