Hello, I'm glad to answer your question. Both of them are better and more distinctive. I suggest you go to the freshman bar to have a nasopharyngeal laryngoscopy, which is a routine examination in the otolaryngology department. Matters needing attention are as follows: 1. Patients should try to have an empty stomach before doing nasopharyngeal laryngoscopy, because some patients will have nausea or even vomiting when doing this examination. If they do it on an empty stomach, nausea and vomiting will be relieved a lot. 2. Local anesthetics, such as dyclonine mucilage and tetracaine, should be used during inspection. Patients should pay attention to whether they are allergic during the use of anesthetic. After using anesthetic, patients should observe whether there are palpitations, palpitations, itching all over the body and throat discomfort, including dyspnea. 3. When doing electronic fiber laryngoscope, the patient will have pain and discomfort, but it is generally within the tolerable range. Therefore, when doing this examination, patients should try their best to overcome psychological fears, maintain emotional stability and cooperate with doctors. 4. Try not to eat or drink water within 2-3 hours after completing the fibrolaryngoscope, because eating or drinking water will easily suffocate or even suffocate due to the effect of anesthetic. There are many routine examinations in otolaryngology, including electronic nasopharyngoscope and nasal endoscope. There are indirect laryngoscope and electronic laryngoscope in pharynx; In listening, there are pure tone audiology, acoustic immittance and ABR. Mainly for the examination of various specialties in otolaryngology.

In addition, there are general, routine and non-specialist examinations, such as CT, color Doppler ultrasound, magnetic resonance, etc., which can be used as otolaryngology examinations. Some invasive tests, such as angiography and intervention, can also be used in otolaryngology.
