Summary

This comprehensive lecture by Professor Zach Murphy covers deep neck infections, emphasizing anatomy, pathophysiology, clinical presentation, and management. It begins with a detailed mapping of the deep neck spaces, including peritonsillar, parapharyngeal, retropharyngeal, and submandibular spaces, and explains how infections spread through fascial planes. The lecture highlights the classic tetrad of symptoms: sore throat, drooling, muffled voice, and fever. It then discusses specific infections: peritonsillar abscess, parapharyngeal abscess, retropharyngeal abscess, and Ludwig’s angina, detailing their causes, clinical features, and potential complications such as airway compromise, mediastinitis, and carotid sheath involvement. The diagnostic approach emphasizes airway assessment and CT imaging, while management includes antibiotics and surgical drainage. The lecture concludes with red flags and the importance of urgent consultation.
