Olfactory dysfunction is commonly seen in COVID-19 patients; however, little is known about the pathophysiology and management. The present study aimed to report a series of cases in which three protocols of intranasal photobiomodulation therapy (PBMT) were used for COVID-19-related olfactory dysfunction. Irrespective of the PBMT protocol, olfaction recovery was noted in all cases but with varying degrees of improvement. Although intranasal PBMT seems to be a promising therapeutic modality, more research is needed to better define effectiveness.
嗅觉功能障碍在 COVID-19 患者中较为常见；然而，其病理生理学和治疗方法知之甚少。本研究旨在报告一系列使用三种经鼻光生物调节疗法（PBMT）方案治疗 COVID-19 相关嗅觉功能障碍的病例。无论采用哪种 PBMT 方案，所有患者的嗅觉恢复情况均有改善，但改善程度不一。虽然经鼻 PBMT 似乎是一种很有前途的治疗方式，但仍需要更多的研究来更好地确定其疗效。
