During the last 150 years, thousands of papers focusing on the effects or side effects of magnetic or radiofrequency fields have been published. They can be categorized as incidental and physiological. [2] Contraindications to MRI include most cochlear implants and cardiac pacemakers, shrapnel and metallic foreign bodies in the eyes.
Below are possible preventive measures and treatment methods that could help in cases of acoustic trauma Hyperbaric Oxygen therapy: Only when the case is extremely serious. [3] Corticosteroids drugs: anti-inflammatory drug. [3] Eardrum repair [9] Using technological assistance for hearing loss such as a hearing aids [5] Ear protection [5]
Note: The complete anatomy of the human ear is extensive, and can be divided into the inner ear and outer ear. The remainder of this article mainly references the cochlea, outer hair cells, and organ of Corti. In general, structural damages to any anatomical part of the human ear can cause hearing-related problems.
Since the inner ear is not directly accessible to instruments, identification is by patient report of the symptoms and audiometric testing. Of those who present to their doctor with sensorineural hearing loss, 90% report having diminished hearing, 57% report having a plugged feeling in ear, and 49% report having ringing in ear ().
Ototoxicity is the property of being toxic to the ear (oto-), specifically the cochlea or auditory nerve and sometimes the vestibular system, for example, as a side effect of a drug. The effects of ototoxicity can be reversible and temporary, or irreversible and permanent. It has been recognized since the 19th century. [1]
Delays of one side relative to the other suggest a lesion in cranial nerve VIII between the ear and brainstem or in the brainstem itself. The most reliable indicator for acoustic neuromas from the ABR is the interaural latency differences in wave V: the latency in the impaired ear is prolonged.
Two shots of J&J's vaccine yields fewer side effects than three shots of Pfizer or Moderna, new CDC data shows. One chart shows the most common COVID-19 booster side effects from Pfizer, Moderna ...
As does any object facing a sound, the ear acts as a passive filter, although the inner ear is not an absolute passive filter because the outer hair cells provide active mechanisms. A passive filter is a low pass : the high frequencies are more absorbed by the object because high frequencies impose a higher pace of compression-decompression to ...
