Eustachian tube dysfunction can be caused by a number of factors. Some common causes include the flu, allergies, a cold, and sinus infections. [6] In patients with chronic ear disease such as cholesteatoma and chronic discharge, studies showed that they have obstructive pathology at the ear side of the Eustachian tube.
In more solid tissues there may be mechanical damage, and the presence of mobile bubbles in the fluids of the inner ear may cause abnormal stimuli. The pathogenesis remains elusive, [13] and may have more than one mechanism. Development of the inner ear injury has been attributed to a vascular mechanism. [13]
Patulous Eustachian tube is a physical disorder. The exact causes may vary depending on the person and are often unknown. [5] Weight loss is a commonly cited cause of the disorder due to the nature of the Eustachian tube itself and is associated with approximately one-third of reported cases. [6]
What causes vertigo and dizziness? ... Peripheral vertigo is caused by a problem in the part of the inner ear that controls balance. (This is the nerve between the inner ear and the brain stem ...
A healthy middle ear is filled with air, not fluid. Having fluid in there can be uncomfortable, serve as a breeding ground for infection, and not to mention cause a lot of pressure and pain in the ...
Endolymphatic hydrops is a disorder of the inner ear. It consists of an excessive build-up of the endolymph fluid, which fills the hearing and balance structures of the inner ear. Endolymph fluid, which is partly regulated by the endolymph sac, flows through the inner ear and is critical to the function of all sensory cells in the inner ear.
Labyrinthitis is inflammation of the labyrinth, a maze of fluid-filled channels in the inner ear. Vestibular neuritis is inflammation of the vestibular nerve (the nerve in the ear that sends messages related to motion and position to the brain). [2] [3] [4] Both conditions involve inflammation of the inner ear. [5]
Ménière's disease (MD) is a disease of the inner ear that is characterized by potentially severe and incapacitating episodes of vertigo, tinnitus, hearing loss, and a feeling of fullness in the ear. [3] [4] Typically, only one ear is affected initially, but over time, both ears may become involved. [3]
