Novel Oro-Nasal Drainage for Long COVID: Proposed Mechanisms – Case Report

Long COVID, potentially emerging post COVID-19 infection, involves extreme health challenges. Based on the current literature in the field, we propose a novel approach to Long COVID treatment based on epipharyngeal abrasive therapy targeting ostia of the oral and nasal mucosa, having been identified for the first time. The presented case report documents the application of innovative Oro-nasal Drainage (OND), a novel treatment integrating physiological, biochemical, and fluid mechanical components simultaneously. OND led to remarkable improvements and even remissions of various symptoms, along with enhanced hand blood circulation. While the case suggests a potential in Long COVID therapy, it is crucial to acknowledge inherent limitations.
