General Otolaryngology – Head and Neck Surgery: Core Principles and Clinical Reasoning
General otolaryngology rewards a disciplined airway-first, anatomy-driven approach. Master the ABCs of the compromised airway (stridor vs. stertor, biphasic vs. inspiratory noise, positioning, and when to move to a surgical airway), the differential of the neck mass by age (congenital/inflammatory in children; neoplastic in adults), and the deep neck space anatomy (retropharyngeal, parapharyngeal, submandibular, peritonsillar, danger space) because spread patterns dictate complications such as mediastinitis, Lemierre syndrome, and airway compromise.
Know the red flags that change management: unilateral nasal obstruction with epistaxis in an adult, a painless hard neck node, hoarseness >3 weeks, dysphagia with otalgia (referred pain), and trismus. Understand the workup hierarchy: history and flexible laryngoscopy first, then imaging (contrast CT for abscess/necrosis; MRI for skull base and perineural disease), then tissue diagnosis.
Traps: equating tonsillitis with peritonsillar abscess (uvular deviation, trismus, hot-potato voice favor abscess); assuming a cystic neck mass in an adult is benign (think HPV-related squamous cell carcinoma); and forgetting that epistaxis control follows a stepwise escalation (pressure, topical vasoconstrictor/cautery, packing, then arterial ligation or embolization). Another trap is attributing referred otalgia to the ear when the primary site is the oral cavity, pharynx, or larynx.
Rule of thumb: In an adult with a persistent unilateral neck mass, the default assumption is malignancy until proven otherwise-obtain fine-needle aspiration and panendoscopy with directed biopsies when indicated.
Worked example: A 55-year-old smoker presents with a 3-cm level II node and a normal oral exam. Flexible laryngoscopy is negative. Next step: contrast CT of neck and chest, FNA of the node, and, if squamous, examination under anesthesia with directed biopsies of the nasopharynx, base of tongue, and pyriform sinus.
