Nasopharyngoscopy is a common method in clinic. Before doing this, the first thing is to remove the fear. This examination is an invasive operation. The patient must actively cooperate with the examination. If the patient moves during the examination, it may cause damage to the nasal mucosa, which may lead to nasal discomfort, or epistaxis. Since vasoconstrictors and surface anesthetics will be sprayed into the nasal cavity before the examination, it is better to have an empty stomach before the examination, or not eat too much, and prohibit eating two hours after the examination, so as not to cause coughing. Attention should be paid to appease children's emotions and let children actively cooperate with inspection and treatment.
