Non-conductive olfactory dysfunction (OD) is an important extra-pulmonary manifestation of coronavirus disease 2019 (COVID-19). Olfactory bulb (OB) volume loss and olfactory network functional connectivity (FC) defects were identified in two patients suffering from prolonged COVID-19-related OD. One patient received olfactory treatment (OT) by the combination of oral vitamin A and smell training via the novel electronic portable aromatic rehabilitation (EPAR) diffusers. After four-weeks of OT, clinical recuperation of smell was correlated with interval increase of bilateral OB volumes [right: 22.5 mm to 49.5 mm (120%), left: 37.5 mm to 42 mm (12%)] and improvement of mean olfactory FC [0.09 to 0.15 (66.6%)].
非传导性嗅觉功能障碍（OD）是2019冠状病毒病（COVID-19）的一种重要肺外表现。在两名患有长期COVID-19相关OD的患者中，发现了嗅球（OB）体积减小和嗅觉网络功能连接（FC）缺陷。一名患者通过口服维生素A和使用新型电子便携式芳香康复（EPAR）扩散器进行嗅觉训练（OT）相结合的方式接受治疗。经过四周的OT，嗅觉的临床恢复与双侧OB体积的间隔增加[右侧：22.5 mm至49.5 mm（120%），左侧：37.5 mm至42 mm（12%）]以及平均嗅觉FC的改善[0.09至0.15（66.6%）]相关。
