In this episode, Professor Zach Murphy delivers a comprehensive, high-yield breakdown of Upper Respiratory Tract Infections in a fully digital format, bringing together the core frameworks from our prior videos and expanding them into one cohesive approach you can use on exams and in real practice. We connect upper airway anatomy to the symptoms that show up every day, including nasal congestion, facial pressure, sore throat, odynophagia, hoarseness, cough, fever, and stridor, while emphasizing the red flags that signal a possible airway emergency. We begin with rhinosinusitis, building a practical way to separate viral illness from bacterial disease using symptom patterns and timeline. Zach walks through mucosal inflammation, impaired sinus drainage, and secondary bacterial overgrowth, then ties it to the features that matter most, including unilateral facial pain, purulent nasal discharge, worsening after initial improvement, and prolonged symptoms. Next, we move into tonsillopharyngitis, focusing on how to evaluate a sore throat safely without over-treating. You will learn how to distinguish common viral causes from group A streptococcal infection, when testing changes management, and how to recognize complications like peritonsillar abscess when symptoms shift toward a muffled voice, uvular deviation, trismus, and difficulty handling secretions. Then we transition into deep neck infections, where anatomy drives everything. Zach breaks down how infections spread through key fascial planes, highlights presentations you cannot miss, and explains why toxic appearance, neck swelling, voice changes, drooling, and respiratory distress should immediately raise concern for rapid progression. We also cover high-yield complications that show up in clinical practice and on exams, including internal jugular vein thrombosis and mediastinal extension. Finally, we cover laryngeal infections and how to localize disease based on symptom patterns, with a strong focus on when hoarseness, stridor, drooling, and severe odynophagia warrant urgent airway-first decisions. We close with a step-by-step digital diagnostic and management framework that integrates all four topics, including when to treat supportively versus when to use antibiotics, when imaging helps versus when it delays care, and when to escalate early to airway-capable teams for definitive management.
