nasendoscopy

Nasendoscopy is a diagnostic procedure used to examine the nasal passages, pharynx, and larynx using a specialized endoscope called a nasendoscope. This minimally invasive technique allows healthcare professionals to visualize the internal structures of the nose and throat in real-time, aiding in the diagnosis of various conditions such as nasal obstructions, sinus diseases, vocal cord problems, tumors, and structural abnormalities.

The procedure typically involves inserting a thin, flexible or rigid tube equipped with a light and camera through the nasal cavity, usually via the nostril. Local anesthesia or topical anesthetic sprays are often used to minimize discomfort. Patients are usually awake during the procedure, which is performed in outpatient settings. The process is generally well-tolerated, with discomfort limited to the brief insertion and inspection phase.

Nasendoscopy provides valuable information beyond what can be observed externally, enabling targeted biopsy, assessment of the sinuses and nasopharynx, and evaluation of auditory and airway functions. It is commonly used by otolaryngologists, otolaryngology specialists, and ENT surgeons. The procedure is also instrumental in preoperative planning, postoperative assessments, and routine examinations for patients with chronic nasal or throat conditions.

Potential risks are minimal but can include nasal bleeding, discomfort, or a vasovagal reaction. Proper technique and patient preparation help minimize these risks. Overall, nasendoscopy is a safe, effective, and essential tool in the diagnosis and management of nasal and upper airway disorders.
