Nasopharyngoscopy can be done for nasal turbinate hypertrophy. As a routine ENT examination, nasopharyngoscopy can examine the nasal cavity, as well as the structures of the nasal cavity such as the upper nasal tract, middle nasal tract, lower nasal tract, and olfactory fissure to clarify the condition and provide a basis for subsequent treatment, but it should be noted that the examination should be performed under local anesthesia (surface anesthesia).
