Temporomandibular Joint Disorder with Eustachian Tube Dysfunction

Clinical Presentation and Diagnosis

The American Academy of Otolaryngology-Head and Neck Surgery recommends that TMJ syndrome is the most common cause of referred otalgia when the ear canal appears normal without middle ear disease 1
Patients with TMJ commonly report pain radiating to the periauricular area and may have a history of bruxism or gum chewing 1
On examination, these patients are tender over the affected TMJ and may have associated crepitus 1

The American Academy of Otolaryngology-Head and Neck Surgery suggests prescribing analgesics based on symptom severity (acetaminophen or NSAIDs for mild-moderate discomfort) 4
Consider muscle relaxants for masticatory muscle tension associated with bruxism 3
Recommend jaw exercises and physical therapy for TMJ rehabilitation 3

The American Academy of Otolaryngology-Head and Neck Surgery advises against prescribing topical or systemic antibiotics, as the clear ear canal without inflammation rules out acute otitis externa, and there is no evidence of middle ear infection 1, 4
Do not miss underlying malignancy, and older patients with persistent otalgia, normal ear examination, and history of tobacco/alcohol use require complete head and neck examination with visualization of mucosal surfaces 1, 2
Do not overlook dental pathology, and in addition to TMJ evaluation, assess for dental caries, impacted molars, or recent dental procedures that could cause referred otalgia 1

Otolaryngology referral is recommended if symptoms persist beyond 2-4 weeks despite conservative TMJ management 3
Urgent ENT evaluation is necessary if cranial nerve deficits, facial paralysis, or severe headache develop 5, 2
Return for re-evaluation if true otalgia, otorrhea, or hearing loss emerges 6, 5
