Key Teaching Points for RGUHS Exam:
- Trismus is the hallmark - differentiates from retropharyngeal abscess
- Swelling is behind posterior faucial pillar - differentiates from peritonsillar abscess
- CECT neck is gold standard for diagnosis and surgical planning
- NEVER paralyze before securing airway - use awake fiberoptic intubation
- Ampicillin-sulbactam is first-line; moxifloxacin for odontogenic (Eikenella)
- Surgery indicated if no improvement at 48-72 hours of IV antibiotics
- Most feared complications: mediastinitis and carotid artery erosion
