Otalgia or ear pain is a multifaceted condition categorized into primary and secondary otalgia. Primary otalgia originates directly from an ear pathology, while secondary otalgia results from referred pain from extraneous sources. The differential diagnoses and evaluation strategies are extensive due to the intricate neural network responsible for ear sensations. Cranial nerves V, VII, IX, and X, and cervical plexus branches C2 and C3, innervate the ear and adjacent structures. The auricle, ear canal, tympanic membrane, and middle ear all receive sensory input from these nerves, creating a complex network allowing for multiple different causes of ear pain. Understanding the relevant neural connections is pivotal for diagnostic accuracy and management effectiveness.Cranial nerve V, encompassing ophthalmic, maxillary, and mandibular divisions, plays a crucial role in sensory innervation to the face, sinuses, palate, and teeth, making it a common culprit in dental and temporomandibular joint pathology. Cranial nerve VII, responsible for taste sensation and facial muscle control, is implicated in geniculate neuralgia when the nervus intermedius is inflamed. Cranial nerves IX and X contribute to otalgia through their connections to the oropharynx, larynx, and distant organs. The activity underscores the collaborative role of the interprofessional team in diagnosing and managing otalgia, considering the diverse neural pathways involved in this intricate sensory experience.
