In this lecture, Professor Zach Murphy delivers a comprehensive, high-yield breakdown of Laryngeal Infections, building a simple but powerful framework for recognizing the dangerous causes of throat and voice symptoms and managing them safely in real patients and on exams. We start on the whiteboard by defining the larynx and the surrounding airway structures, then connect the anatomy to why hoarseness, stridor, dysphagia, and respiratory distress can signal anything from a self-limited illness to an impending airway emergency. We begin by mapping the major infectious patterns that involve the larynx, then walk through the core pathophysiology that drives symptoms, including mucosal inflammation, edema, airway narrowing, impaired vocal cord vibration, and reactive secretions. From there, Zach breaks down acute laryngitis, explains why most cases are viral and improve with supportive care, vocal rest, and hydration, and highlights the key features that should make you pause and think beyond routine laryngitis. Next, we cover supraglottic infections, with a high-yield focus on epiglottitis and how it presents differently across ages. You will learn the clinical warning signs that matter most, including rapid onset fever, severe odynophagia, muffled voice, drooling, tripod positioning, and stridor, and why agitation and repeated throat exams can be dangerous when the airway is unstable. We then transition to croup and bacterial tracheitis, explaining how to distinguish them clinically and why their management differs. Zach ties the symptoms to airway level involvement and emphasizes the exam patterns that help you separate a barking cough with inspiratory stridor from a toxic appearing child with progressive airway obstruction and thick secretions. Finally, after the whiteboard, we build on a digital diagnostic and management framework that walks you step by step through evaluation and treatment. You will learn how to prioritize airway assessment, when to escalate early to airway-capable teams, when imaging can help versus when it delays care, and how to choose therapies like nebulized epinephrine, corticosteroids, and appropriate antibiotics when bacterial disease is suspected.
