Final answer:
In otitis externa, moving the pinna and tragus causes pain. It's different from otitis media and inner ear conditions like Ménière's disease and tinnitus.
Step-by-step explanation:
In otitis externa, the patient experiences pain when the pinna and tragus are moved. Otitis externa, often referred to as "swimmer's ear," is an inflammation of the ear canal. This condition is quite different from otitis media, which affects the middle ear, or from Ménière's disease and tinnitus, which are related to inner ear issues and hearing disturbances like vertigo, hearing loss, and phantom sounds, rather than to pain from the pressure or movement in the outer ear structures. Ménière's disease is a degenerative condition of the inner ear that can cause hearing loss, tinnitus, vertigo, and increased pressure in the ear. It is not treated with hearing aids but some individuals might be candidates for a cochlear implant.
