The ENT specialist Dr. Christopher Chang describes the various anatomy objects he encounters during a trans-nasal endoscopy: " This procedure is also called rhinoscopy. These exams are performed without any sedation and are easily tolerated by patients as young as 5 years of age with their full cooperation. Prior to examination, the nose is decongested and anesthetized with a nasal spray."
