There are various types of laryngoscopes in clinical practice, such as indirect laryngoscope, direct laryngoscope, supported laryngoscope, and fiberoptic laryngoscope. Indirect laryngoscopes and fiberoptic laryngoscopes are commonly used in outpatient clinics. If only the tonsils, soft palate and epiglottis need to be viewed, the doctor can observe them with the tongue depressor or indirect laryngoscope when the patient opens his mouth, and fiberoptic laryngoscopy is not necessary. However, if you need to see the nasopharynx, hypopharynx and larynx due to certain diseases such as swollen lymph nodes in the neck, blood in the snot, hoarseness, obstruction of swallowing, difficulty in breathing, etc., you need to do fiberoptic laryngoscopy. The fiberoptic laryngoscope has a certain magnification, which enables a more careful observation and a clear diagnosis before further symptomatic treatment.
