Can an endoscopy see throat problems?

Yes, an endoscopy, specifically a throat or nasal endoscopy (laryngoscopy), can effectively visualize throat problems like inflammation, vocal cord issues, growths, and swallowing difficulties, using a thin tube with a camera to get a detailed view of the voice box and surrounding structures, often to diagnose causes of hoarseness, pain, or trouble breathing. It provides a clear look at the larynx and pharynx, allowing doctors to identify issues like polyps, tumors, or reflux signs, and can even take biopsies if needed.

Can an endoscopy detect throat issues?

Using a scope to get a closer look at your throat.
