DIAGNOSTIC NASAL ENDOSCOPY (DNE) is a minimally invasive procedure used to examine the nasal passages, sinus openings, and the back of the nose using a thin, flexible or rigid endoscope fitted with a high-definition camera. The procedure provides a clear and detailed view of the nasal cavity, allowing ENT specialists to accurately assess the condition of the nose and surrounding structures. It is quick, safe, and typically performed under local anesthesia in an outpatient setting.
DNE is commonly recommended for patients with chronic nasal blockage, recurrent sinus infections, nasal polyps, nosebleeds, allergies, or unexplained nasal symptoms. It helps diagnose conditions such as sinusitis, deviated nasal septum (DNS), nasal tumors, and other structural abnormalities. Early and accurate diagnosis through DNE enables timely treatment, improving breathing, relieving symptoms, and promoting better nasal and sinus health.
