Postviral Olfactory Disorder / 대한이비인후과학회지

ABSTRACT

Postviral olfactory disorder (PVOD) is a sensorineural olfactory loss following an upper respiratory tract infection (URTI) and there is a close temporal connection between PVOD and URTI. PVOD is more common in women over 50 years of age. A thorough otolaryngologic evaluation including history, physical examination, neurologic assessment, and olfactory function test is mandatory to diagnose PVOD. Spontaneous recovery might occur in some patients from 6 months to several years. Although many drugs have been tried to treat it, no effective medical treatment exists. Patients should be counseled regarding safety issue and quality of life issue.
