Why do I experience hearing loss and a lack of acoustic reflex in the ear?

Hi,

Welcome to icliniq.com.

Loss of acoustic reflex in one ear usually means some conductive loss, usually in the middle ear. The MRI (Magnetic resonance imaging), including an angiogram of the inner ear, was done to exclude inner ear causes. It would have been helpful if you had included some more information, such as whether you have got any middle ear infection, any trauma over the head or ears, whether it developed gradually or suddenly, and whether your hearing loss is complete or partial. It would be helpful to know whether you have tinnitus or vertigo.

According to the MRI (magnetic resonance imaging), the inner ears look perfect on both sides with no abnormal fluid collection or signal defect and contrast enhancement. The inner ear's nerves (facial, cochlear, vestibular) are properly positioned.

Labyrinthine arteries (that supply the inner ear) arise from basilar on both sides, which is found in about 12 percent of the population and is not considered an anomaly. The right labyrinthine artery forms a loop within the inner ear canal, but it is also not considered to be an anomaly by most doctors and researchers.

In particular, there is no mass lesion, abnormal signal, or contrast enhancement within the brainstem and the nerves mentioned above.

The MRI (magnetic resonance imaging) scan showing the inner ear, including all nerves and arteries, and the brain does not reveal any abnormality. The middle ear, which is the potential location of the causes of your hearing loss, is not very clearly demonstrated in the imaging sequences provided here, so I can not comment on that.

Thank you.
