Sorry, no etymologies found.
The evidence of otosclerosis on the CT scan was very subtle, so it is not surprising that the general radiologist was not able to identify the pathology.
In this case, the radiologist read the CT scan as normal and not showing signs of otosclerosis.
Our radiologist located the otosclerosis adjacent to the stapes.
Other conditions can also cause tinnitus, such as otosclerosis where the bones in the middle ear become stiff, a build-up of ear wax, middle-ear infections, a head injury and a perforated ear drum.
Other problems associated with tinnitus include wax build-up and other obstructions in the outer ear, fluid accumulation, a ruptured eardrum, an infection in the middle ear, and excess bone growth (known in the medical field as otosclerosis).
While at Radcliffe, she experienced permanent hearing loss, diagnosed as otosclerosis.
A gene responsible for the single most common cause of hearing loss among white adults, otosclerosis, has been identified for the first time, a scientist told the annual conference of the European Society of Human Genetics in Nice, France.
Ms Thys and her team decided to study a gene called TGBF1 which they already knew had non-genetic indications of involvement in otosclerosis: it plays a role during embryonic development of the ear and is expressed in otosclerotic bone.
Ms Melissa Thys, from the Department of Medical Genetics, University of Antwerp, Belgium, said that this finding may be a step towards new treatments for otosclerosis, which affects approximately 1 in 250 people.
When I was about ten years old the first signs of deafness (from otosclerosis) became noticeable.
