Study Notes

Outer Ear Conditions

Exostoses are bony growths in the ear canal caused by prolonged exposure to cold water. They can lead to ear infections and blockage.
Keloids are abnormal scar tissue growths that form after ear trauma, such as piercings, surgery, or injuries.
Ear cysts are fluid-filled sacs that can develop within or around the ear. Sebaceous cysts are the most common type.

Middle Ear Conditions

Otitis media (middle ear infection) can be caused by viral or bacterial infections.
Mastoiditis is a complication of otitis media where the mastoid air cells become inflamed. It can lead to meningitis or intracranial abscess if left untreated.
Ménière's disease is characterized by endolymph fluid buildup in the inner ear, resulting in vertigo, hearing loss, and tinnitus.

Inner Ear Conditions

Vestibular paroxysmia is a rare condition that causes sudden and intense episodes of dizziness and vertigo.
Cochlear nerve deficiency includes cochlear nerve hypoplasia (underdevelopment) and aplasia (complete absence).
Labyrinthitis is inflammation of the inner ear, often caused by viral infections or bacterial infections.
Vestibular neuritis (vestibular neuronitis) is inflammation of the vestibular nerve, which affects balance and causes dizziness.
Ramsay-Hunt syndrome is caused by reactivation of the varicella-zoster virus, leading to ear pain, hearing loss, facial paralysis, and a rash.
