Search titles only; Posted by Member: Separate names with a comma. This is really a good find. Mastoiditis is exactly what is sounds like. To really understand T, there needs to be a better imaging process that can look "inside" the cochlea.

Let me just add that I don't like the approach where a slit is made to fold the ear drum flap down. I think they already found it. 0000001888 00000 n

The problem with MRIs (and even CAT scans) is that they cannot see inside the inner ear.

Good example of a normal IAC MRI. [3] This technique has not met with the same clinical success as transtympanic endoscopy because of the small image size provided by the scope, difficult orientation, and poor illumination. Imaging was conducted using a MR device with a power of 1.5 Tesla (1.5T GE Signa HDxt scanner; General Electric Healthcare, Pittsburgh, PA, USA) and a brain coil (8-channel HD Brain Coil). Incidental left posterior temporal lobe developmental venous angioma.

Perpendicular to IAC, oblique-sagittal and mediolateral tilted orientated planning images were obtained. In the practice of neurotology, magnetic resonance imaging (MRI) of the brain and internal auditory canals (IACs) is often employed as a necessary tool in the workup of hearing loss, tinnitus, vertigo and other presenting symptoms. They can only show the structure of the semicircular canals and auditory channel (outer ear). It is the inflammation of the mastoid air cells that are in the temporal bone. The lumbosacral spine is made up of the five lumbar vertebral bones (L1 thru L5), the sacrum (the bony “shield” at the bottom of your spine), and the coccyx (tailbone). 0000005554 00000 n
Magnetic resonance imaging (MRI) has been accepted as a sensitive imaging method to identify lesions in the cerebellopontine angle (CPA), internal auditory canal (IAC), and inner ear in patients with SSNHL.1The American Academy of Otolaryngology—Head and Neck Surgery recommended that patients with SSNHL undergo audiometry and MRI of the middle and inner ear.2

I would much prefer an approach where the endoscope is slid up the Eustachian tube (assuming it could be done without breaking it).In 1989, Kimura introduced the concept of endoscopy of the middle ear through the eustachian tube orifice. To really understand T, there needs to be a better imaging process that can look "inside" the cochlea.The problem with MRIs (and even CAT scans) is that they cannot see inside the inner ear. 0000002357 00000 n

The pathology for the IAC portion I have chosen to do is Mastoiditis which sounds pretty painful. xref
< Chronic mastoiditis usually is latent and does not show up for a while. I think they already found it. 0000002994 00000 n
