If you visit an ENT doctor with sinusitis nasal polyps, or other ENT diseases, the doctor will sometimes recommend that you undergo a sinus endoscopy (nasal endoscopy, nasal endoscopy).
The doctor will usually spray a surface anesthetic, usually 1% cocaine, into the patient’s nasal cavity before performing the endoscopy, and the endoscope will be ready for examination about 5 minutes after the spray.
During the examination, the patient can be seated or semi-recumbent, and the doctor will insert the nasal endoscope into the patient’s nasal cavity, and then carefully examine the parts that need to be understood. For example, the hooks in the middle nasal tract, the sieve vesicle, the opening of the maxillary sinus, the olfactory fissure, the opening of the eustachian tube in the nasopharynx and the adenoid tissue.
In many hospitals, the nasal endoscope can be synchronized with a TV monitor to provide a clearer view. After the examination, some ENT departments will print the results of the examination in the form of pictures and give them to the patient, or save them directly in the computer for information. A camera system can also be used to record the complete examination process.
Nasal endoscopy is important for the early detection of malignant nasal polyps and various nasal sinus diseases, and nasal endoscopy has become an effective tool for ENT doctors to diagnose and treat rhinological diseases.
