A fiberoptic and electronic laryngoscopy usually takes about 2 to 5 minutes. If it is just a simple laryngoscopy, the process is smoother and the patient cooperates better, the examination time will be shorter and usually takes about 2 to 5 minutes. However, laryngoscopy needs to be preceded by preparations such as screening for infectious diseases, a process that takes relatively longer. When laryngoscopy is performed, the laryngoscope passes through the nasal cavity, nasopharynx, oropharynx and laryngopharynx in turn, during which the nasal cavity, nasal septum, adenoids, tonsils, root of the tongue, epiglottis, epiglottic valley, vocal cords, ventricular cords, pyriform fossa and other structures need to be observed in turn, and the whole process takes about 2 to 5 minutes. However, if not only laryngoscopy, but also need to do at the same time pathological examination, vocal cord nodule removal, vocal cord polyp removal, etc., need to do the relevant preparations before the operation, then laryngoscopy process will be longer. If you need to do laryngoscopy, it is recommended that patients make an appointment in advance, consult with a professional doctor in time, and actively cooperate with the examination, and generally the results can be obtained after the examination.
