Exploratory tympanotomy is used when the diagnosis is in doubt and it is felt that direct microscopic visualization will significantly aid diagnosis and enhance planning of middle ear surgery. To detect conductive hearing loss caused by ossicular fixation, incus discontinuity and otosclerosis is easier with 3D CT imaging. No need of exploratory tympanotomy for diagnostic purpose alone, but can be useful if surgery is considered at the same time. Otosclerosis is a condition that affects the stapes, one of the tiny bony ossicles in the middle ear. 3D CT proved valuable in detecting otosclerosis, foci of demineralization, and changes in bony texture and enables the easy recognition of subtle radiographic findings. 3D CT proved valuable in determining otosclerotic changes of the oval window and otic capsule. Hearing aids can be very helpful and it makes sense to try them before considering surgery. Dr Paulose FRCS, DLO is a Consultant ENT Plastic & Laser Surgeon with over 38 years of world class experience in Ear, Nose, Throat and Laser Surgery treating patients across the world from UK, US, Middle East to Asia. When you come in to see us for a hearing test, we put you in the sound booth and put foam insert earphones in your ears. However, if you are like me, you will see that the line starts high, and then drops as it runs to the right. That means that the high tones have to be quite a bit louder before I hear them, so I’m not hearing the birds chirping or the water running, and the high notes of music are thin. A successful evening with a full-house at Chears Audiology listening to Katherine Bouton discuss living with hearing loss and being an advocate.


Anyone who has a child understands the frustration that occurs when a child does not reach a milestone, whether it be hitting the growth chart at the appropriate level, saying his first word, or running across the hall. Some hearing loss causes include damage to the inner ear, a buildup of earwax, infections and a ruptured eardrum. Hearing occurs when sound waves reach the structures inside your ear, where the sound wave vibrations are converted into nerve signals that your brain recognizes as sound.
Attached to nerve cells in the cochlea are thousands of tiny hairs that help translate sound vibrations into electrical signals that are transmitted to your brain.
Damage to the inner ear. Aging and prolonged exposure to loud noise may cause wear and tear on the hairs or nerve cells in the cochlea that send sound signals to the brain.
A gradual buildup of earwax. Earwax can block the ear canal and prevent conduction of sound waves.
Ear infection and abnormal bone growths or tumors. In the outer or middle ear, any of these can cause hearing loss. Ruptured eardrum (tympanic membrane perforation). Loud blasts of noise, sudden changes in pressure, poking your eardrum with an object and infection can cause your eardrum to rupture and affect your hearing. MSHA has developed a series of presentations that can be used by the mining community as a training resource in the area of noise and hearing loss prevention.
In patients who presents with conductive hearing loss due to middle ear abnormalities can be diagnosed by 3DCT imaging.
To have normal hearing, the ossicles need to be able to move freely in response to sound waves. Bone is continually being broken down and remodeled but the remodeling process of the stapes becomes faulty.


The stapes footplate is fixed when the spongiotic focus expands and invades the oval window. However, otosclerosis will continue to progress and hearing aids will not stop you developing profound deafness in the long term.
However, if you suffer from tinnitus, surgery may not relieve this and if your inner ear is also affected, surgery may not improve your hearing either.
The intention of the microphone is to bring the source of speech closer to the person who is using the hearing aid. The vibrations of different sounds affect these tiny hairs in different ways, causing the nerve cells to send different signals to your brain. When these hairs or nerve cells are damaged or missing, electrical signals aren’t transmitted as efficiently, and hearing loss occurs. When the tympanic membrane is intact, the only way to find out the state of the middle ear structures are by doing an operation called exploratory tympanotomy. The eardrum and three small bones of the middle ear — the hammer, anvil and stirrup — amplify the vibrations as they travel to the inner ear.
There, the vibrations pass through fluid in the cochlea, a snail-shaped structure in the inner ear. This abnormal bone reduces the movement of the stapes, which reduces the amount of sound that is transferred to the cochlea.
