Nasal endoscopy, a member of the endoscopic family, is a new technique on the rise of nasal surgery. In order to examine the deep cavities of the nasal cavity, the pioneers of otorhinolaryngology have been exploring better and more effective methods. Initially, cystoscopy was applied to examine the nasal cavity, and then it was developed to a nasal endoscope for rhinology, during which nearly half a century has passed. The nasal endoscope is a rigid tuboscope that has different views and its good optical magnification imaging system makes it more visual and accurate for the diagnosis of nasal cavity, sinus and nasopharyngeal diseases.
The nasal endoscopy system mainly consists of: nasal endoscope, light source, camera system, monitor, video and hard disk storage system, etc. The combination of nasal endoscopy system and computer technology, imaging and image storage and analysis system provides a new way to accumulate clinical data and carry out research and teaching.
The application of nasal endoscopy is like a doctor’s eye entering the patient’s nasal cavity. Its good illumination and optical magnification imaging system can detect the lesions in the nose and nasopharynx timely and accurately, such as nasopharyngeal cancer, nasal sinus tumor, nasal polyp, sinusitis and the site of nasal bleeding, in order to treat them timely and effectively. It can be said that nasal endoscopy is the “patron saint” of nasal health.
