COMPREHENSIVE CLINICAL ANALYSIS OF RHINOSINUSITIS: PATHOPHYSIOLOGY AND MULTI-MODAL TREATMENT

Abstract

Rhinosinusitis represents a widespread and multi-layered inflammatory process of the nasal cavity and paranasal sinuses that imposes a substantial socioeconomic and clinical burden worldwide. This analytical review provides an extensive examination of rhinosinusitis, tracing its trajectory from intricate cellular immunopathology and molecular endotyping to state-of-the-art therapeutic paradigms. We explore the critical synergy between advanced non-pharmacological interventions, conventional topical therapies, and the emerging revolution of "pathway-specific" biologic agents, such as monoclonal antibodies. Furthermore, this review addresses the underlying drivers of clinical heterogeneity, the impact of stubborn microbial biofilms, and the challenges of managing recalcitrant disease variants. By integrating physiological thresholds, anatomical barriers, and host immune responsiveness, this work highlights the clinical necessity of transitioning toward a highly personalized, endotype-driven framework in modern otorhinolaryngology.
