Office-Based Laryngology.

Injection laryngoplasty was first described by Dr Charles Bruening in 1911 with the injection of paraffin for vocal cord paralysis. The most common indication for injection laryngoplasty is glottic insufficiency causing dysphonia and/or dysphagia and aspiration. Etiologies of glottic insufficiency include vocal fold immobility, vocal fold hypomobility, sulcus vocalis/vocal scar, and vocal fold atrophy. In-office laryngology procedures, made possible by advancements in equipment and endoscopy, offer numerous benefits including cost-effectiveness, avoidance of general anesthesia, efficiency, and a high safety profile. These procedures can be easily performed in carefully selected patients.
