Glottic insufficiency, or glottic gap as it is commonly called, is a common cause of dysphonia, producing symptoms of soft voice, decreased projection, and vocal fatigue. Treatment of glottic gap can include surgical and behavioral therapies or a combination of the two. When surgery is chosen, closure of the glottic gap is the primary goal. The commercially advertised modalities can cause variable treatment results. This panel will review the etiologies of glottic gap in geriatric, adult and pediatric populations, an evidence-based analysis of the options for treatment of glottic gap in geriatric, adult and pediatric populations, including video presentations of surgical approaches, and patient scenarios illustrating the indications for temporary and permanent injection medialization laryngoplasty, thyroplasty, and other surgical treatment modalities.
