A patient reports ear fullness and jaw locking. What is the most likely condition?

• A. Otitis media
• B. Meniere's disease
• C. Sinusitis
• D. TMD

Answer: (D)

Ear fullness combined with jaw locking points to a problem with the temporomandibular joint. The TMJ is located right near the ear, so dysfunction there can produce ear-related sensations such as fullness or pressure even when the inner ear is normal. When the disc is displaced or the jaw muscles are in spasm, the mouth can lock or have limited opening, which is a hallmark sign of a TMJ disorder. Other conditions don’t usually explain both symptoms together: an ear infection would typically bring fever or ear-specific findings; Meniere’s disease causes vertigo and fluctuating hearing loss; sinusitis leads to facial pressure and nasal symptoms. So the presentation best fits a temporomandibular disorder.
