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.
This type of presentation was common prior to development of antibiotic treatments, and is now a rare complication. [citation needed] In persons with longstanding ear infection and typical symptoms, medical imaging such as CT or MRI of the head may show changes that confirm disease involvement of the petrous apex of temporal bone. [citation needed]
There can be damage either to the ear, whether the external or middle ear, to the cochlea, or to the brain centers that process the aural information conveyed by the ears. Damage to the middle ear may include fracture and discontinuity of the ossicular chain. [77] [78] Damage to the inner ear (cochlea) may be caused by temporal bone fracture ...
In January 2024, BMJ Public Health published a systematic review of 14 studies investigating associations between sound-induced hearing loss and playing video games and esports that found a significant association between gaming and hearing loss or tinnitus and that the average measured sound levels during gameplay by subjects (which averaged 3 ...
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.
Low-frequency conductive hearing loss is present in many patients with SCDS and is explained by the dehiscence acting as a "third window." Vibrations entering the ear canal and middle ear are then abnormally diverted through the superior semicircular canal and up into the intracranial space where they become absorbed instead of being registered ...
Nearly one billion Gen Z and Millennials are at risk of hearing loss due to excessive headphone use. Learn the pros and cons of noise-canceling earbuds (or headphones), and how to prevent hearing ...
Cochlear hydrops preferentially affects the apex of the cochlea where low-frequency sounds are interpreted. Due to the fluid imbalance in this area, parts of the cochlea are stretched or under more tension than usual, which can lead to distortions of sound, changes in pitch perception, or hearing loss, all usually in the low frequencies.
