In-Office Laryngology Injections.

The ability to perform in-office vocal fold injections has been greatly enhanced by advances in videolaryngoscopy technology. With improved optics and thin, channeled flexible laryngoscopes, in-office laryngeal injections have expanded from vocal fold augmentation for glottic insufficiency, vocal cold immobility, and botulinum toxin injections for spasmodic dysphonia, to vocal fold steroid injections for benign vocal fold lesions and scars and various injections for neurogenic cough. Efficacy, approaches, post-procedure management, and common complications of in-office laryngeal injections are outlined and supporting evidence discussed.
