Abstract
We present a sniffing bead system used to diagnose olfactory dysfunction in coronavirus disease2019 (COVID-19) patients. A 25-year-old male presented with the loss of olfaction oneweek after he was diagnosed with severe acute respiratory syndrome coronavirus 2 (SARSCoV-2). He had no other symptoms such as fever or myalgia but only showed an absence ofrespiratory distress. Nasal endoscopy and paranasal sinus CT showed that the patient had nobilateral sinus diseases; cranial nerve MRI showed no abnormal signal intensity or enhancement.
A sniffing bead system was applied using 2-phenylethyl alcohol for the objective assessmentof olfactory dysfunction to confirm the presence of anosmia. Anosmia was diagnosedearly by objective evaluation using a sniffing bead system and early intervention with olfactorytraining. This case report suggests that a verified, one-off system for objective measurement ofolfactory dysfunction in COVID-19 with olfactory training in patients could facilitate the recoveryof olfactory function.

Sniffing bead system applied to our COVID-19 patient for evaluation of olfactory dysfunction. A sniffing bead system was applied using 2-phenylethyl alcohol for the objective assessment of olfactory dysfunction to confirm the presence of anosmia. Anosmia was diagnosed early by objective evaluation using a sniffing bead system and early intervention with olfactory training.
