Endoscopy is a modern medical procedure that allows doctors to see inside the body using a thin, flexible tube with a camera and light. In ENT care, nasal endoscopy and laryngeal endoscopy are commonly used to examine the nose, sinuses, throat, voice box, and upper airway. These procedures help diagnose conditions such as nasal blockage, sinus infection, polyps, voice problems, throat pain, swallowing difficulties, and suspected growths.
Nasal endoscopy involves passing a small scope through the nostril to view the nasal passages and sinuses. Laryngeal endoscopy involves examining the voice box and surrounding structures, either through the nose or mouth. Both procedures are usually quick, well tolerated, and done in a clinic or procedure room. They provide clear, magnified images that help the doctor make an accurate diagnosis and plan treatment.
What is Nasal Endoscopy?
Nasal endoscopy is a procedure where a thin, flexible or rigid tube with a camera and light is passed through the nostril to examine the inside of the nose and sinuses. The tube is called an endoscope. It is connected to a monitor that displays magnified images in real time.
The procedure allows the doctor to see the nasal passages, nasal septum, turbinates, sinus openings, adenoids, and the back of the nose near the throat. It helps identify inflammation, infection, polyps, structural abnormalities, bleeding points, or growths that cannot be seen with a simple torch examination.
Nasal endoscopy is commonly done in an ENT clinic. It usually takes only a few minutes. Most patients tolerate it well with minimal discomfort. It is a key tool for diagnosing chronic sinusitis, nasal polyps, recurrent nosebleeds, nasal obstruction, and suspected tumors.
What is Laryngeal Endoscopy?
Laryngeal endoscopy is a procedure where a thin scope is used to examine the voice box, also called the larynx, and surrounding structures. This includes the vocal cords, epiglottis, and upper part of the windpipe. The procedure helps assess voice problems, throat pain, difficulty swallowing, chronic cough, and suspected lesions.
There are two main types of laryngeal endoscopy. Flexible laryngoscopy is done through the nose using a flexible scope. Rigid laryngoscopy is done through the mouth using a rigid scope, often in an operating room under anesthesia. For most routine evaluations, flexible laryngoscopy in the clinic is sufficient.
Laryngeal endoscopy provides a clear view of the vocal cords in action. The doctor can see how the cords move during breathing and speaking. This helps diagnose vocal cord nodules, polyps, paralysis, inflammation, reflux-related changes, and other conditions affecting the voice and airway.
Why are These Procedures Done?
Nasal and laryngeal endoscopy are done to investigate symptoms, confirm diagnoses, and guide treatment.
