nasolaryngoscopy

Nasolaryngoscopy is a diagnostic procedure used to examine the nasal passages, pharynx (throat), and larynx (voice box). It involves the use of a flexible or rigid endoscope, a thin, lighted tube with a camera. The endoscope is typically inserted through the nostril and advanced down into the throat and larynx.

The procedure is performed by trained medical professionals, usually an otolaryngologist (ear, nose, and throat doctor). Local anesthetic spray may be applied to the nasal passage to numb the area and reduce discomfort. The patient is usually asked to breathe normally through their nose during the examination.

Nasolaryngoscopy is used to diagnose a variety of conditions affecting the nose and throat. This can include nasal obstruction, chronic sinusitis, nasal polyps, voice disorders, difficulty swallowing, and suspicion of tumors or other growths in the upper airway. It allows for direct visualization of tissues that are not easily seen with standard examination techniques.

The examination is generally well-tolerated and is an outpatient procedure. Recovery is typically quick, with patients often able to resume normal activities shortly after the examination. Potential risks are minimal but can include temporary nasal irritation or bleeding. The information gathered from a nasolaryngoscopy aids in accurate diagnosis and the development of an appropriate treatment plan.
