Nasal endoscopy is a diagnostic procedure that uses a thin, flexible tube called an endoscope, equipped with a light and camera, to examine the nasal passages, sinuses, and upper part of the throat. The procedure allows doctors to get a clear view of these areas to diagnose conditions such as sinusitis, nasal polyps, tumors, structural abnormalities, or chronic nasal obstruction. It is typically performed in a doctor's office under local anesthesia to minimize discomfort. During a nasal endoscopy, the endoscope is gently inserted through the nostril, providing real-time images on a monitor, which helps the doctor assess the anatomy and pathology of the nasal cavity and sinuses.
Nasal endoscopy is often indicated for patients experiencing persistent symptoms such as nasal congestion, sinus pain, recurrent sinus infections, or unexplained nosebleeds. It can help identify the cause of these symptoms and guide further treatment. While nasal endoscopy is generally safe and well-tolerated, there are some potential complications. Patients may experience temporary discomfort, a stinging sensation from the local anesthetic, or a mild nosebleed due to minor trauma to the nasal lining during the procedure. Rarely, more significant bleeding or infection may occur, especially in patients with underlying bleeding disorders or those on blood-thinning medications. To minimize risks, it is important for patients to inform their doctor of their medical history and any medications they are taking. Nasal endoscopy is a valuable tool for accurate diagnosis and effective management of nasal and sinus conditions.
