Objectives/Hypothesis: This study examined changes in voluntary cough airflow measures immediately following in-office injection of Radiesse in patients diagnosed with glottic insufficiency. Due to significant comorbidities, these patients were poor candidates for medialization under general anesthesia. Each patient presented with dysphonia and dysphagia and ineffective voluntary cough, resulting in a poor clearing of secretions and a presence of ingested fluids on examination. Study Design: Prospective cohort and case series study. Methods: Three patients with a diagnosis of glottic insufficiency were included for study based on flexible endoscopy and laryngostroboscopic examination. Voluntary cough airflow measures were obtained approximately 30 minutes before and after the Radiesse injections. The airflow measures were: compression phase duration (CPD), expiratory rise time (EPRT), expiratory phase peak airflow (EPPF), and cough volume acceleration (CVA). Results: Injection of Radiesse was found to improve voluntary cough airflow measures. Conclusion: The immediate increase in the objective airflow measures obtained from voluntary cough production after Radiesse injections can be used to document airway protection improvements. Cough airflow is a straightforward measure to obtain and is considered an objective measure of cough function.
