Abstract In this study, the critical role of epipharynx in managing long-term coronavirus disease 2019 (COVID-19), and particular, how residual SARS-CoV-2 RNA affects signalling pathways were investigated via spatial gene expression analysis (Visium HD). Moreover, we hypothesize that epipharyngeal abrasive therapy (EAT) targeting could improve long COVID symptoms by modulating local inflammation expression. We conducted a comparative profiles three patients with two control individuals without COVID-19. Residual was detected COVID, along activation epithelial immune cells. After EAT, viral either completely cleared or significantly reduced. T-cell receptor suppressed; levels proinflammatory cytokines, such as interleukin-6 tumour necrosis factor-α, reduced; excessive antibody production mitigated. Histology showed EAT effectively eliminated inflamed, dysfunctional ciliated epithelium. This study clarifies has effects on response epipharynx, emphasizing need to focus chronic epipharyngitis potential cause COVID. Furthermore, may offer promising approach alleviating persistent symptoms.

Post/Long COVID (syndrome) is defined as a condition with symptoms persisting for more than 12 weeks after the onset of SARS-CoV-2 infection that cannot be explained otherwise. The prevalence self-reported otorhinolaryngological high. aim this review was to analyze current literature regarding actual prevalence, knowledge etiopathology, and evidence-based treatment recommendations otorhinolaryngology-related symptoms. A systematic search articles published since 2019 in PubMed ScienceDirect performed resulted 108 articles. These were basis formed comprehensive series consented therapy statements on most important Otorhinolaryngological did not appear isolated but part multi-organ syndrome. Self-reported often confirmed by objective testing. estimated anosmia, dysgeusia, cough, facial palsy, hoarseness/dysphonia, acute hearing loss, tinnitus, vertigo/dizziness about 4%, 2%, 4-19%, 0%, 17-20%, 8%, 20%, 5-26%, respectively. There are manifold theoretical concepts etiopathology different symptoms, there no clear proof. This certainly contributes fact effective specific option any mentioned. Healthcare pathways must established so can recognized evaluated otorhinolaryngologists provide counseling. would also help establish selectively include patients clinical trials investigating therapeutic concepts.
