Introduction
Fiberoptic nasopharyngoscopy is a method that uses fiberoptic equipment and microscopic technology to examine and treat lesions in the nasopharyngeal region. During the procedure, after anesthesia is administered, the fiberoptic nasopharyngoscope is inserted through the mouth, carefully guided and directed under direct vision to reach and examine the nasopharynx. It is recommended that fiberoptic nasopharyngoscopy be performed at a reputable hospital by qualified medical professionals.
Generally, fiberoptic nasopharyngoscopy is a method that uses fiberoptic equipment and microscopic technology to examine and treat lesions in the nasopharyngeal region. The specific procedure is as follows:
1. The patient should fast from food and water for four hours prior to the examination.
2. Topical anesthesia is applied to the mucous membranes of the patient's nose, pharynx, and larynx.
3. After anesthesia, the fiberoptic nasopharyngoscope is inserted through the mouth. Under direct vision, the scope is guided toward the nasopharynx for observation.
4. Upon completion of the observation, the fiberoptic nasopharyngoscope is withdrawn, the patient's face is wiped dry, and the examination concludes.
Fiberoptic nasopharyngoscopy is not suitable for patients with severe heart or lung diseases. It is recommended that patients visit a正规 medical institution where the procedure can be performed by a qualified physician.
