EN4.1 | Otalgia — Summary & Reflection

KEY TAKEAWAYS

Otalgia may be primary (otogenic — from the ear itself) or referred (non-otogenic — from distant structures sharing sensory nerve supply). Five nerve pathways mediate referred otalgia: CN V (dental, TMJ), CN VII (Ramsay Hunt syndrome/herpes zoster oticus), CN IX (tonsillitis, oropharyngeal carcinoma), CN X/Arnold's nerve (hypopharyngeal/laryngeal carcinoma), and C2–C3 great auricular nerve (cervical spondylosis). In adults, up to 50% of otalgia cases have no primary ear pathology — referred causes dominate. Examination protocol: otoscopy (both ears) → oral cavity + oropharynx → TMJ palpation → indirect laryngoscopy/fibreoptic nasopharyngolaryngoscopy → neck palpation. The critical rule: unexplained unilateral adult otalgia with normal ear examination = mandatory full H&N examination to exclude malignancy. Key causes by examination: normal ear + dysphagia/weight loss in smoker → hypopharyngeal/laryngeal carcinoma (Arnold's nerve); vesicles EAC + facial palsy → Ramsay Hunt (VZV, geniculate ganglion); pre-auricular pain on jaw movement → TMJ dysfunction (Costen's syndrome); post-tonsillectomy ear pain → referred via CN IX. Myringotomy site: antero-inferior quadrant. Management is cause-directed.

REFLECT

The hook scenario describes a patient whose otalgia was dismissed because his ear examination was normal. Reflect on the following: what systemic factors (time pressure, cognitive shortcuts, prior experience) lead a clinician to stop after a normal otoscopic examination without proceeding to a full head-and-neck examination? What personal safeguards — a mental checklist, an explicit questioning habit — could you build into your clinical practice to prevent this error? Write two to three sentences in your reflective journal describing how you would approach an adult otalgia consultation differently after completing this module.
