A pathological change that occurs in the middle and inner ear, causing progressive impairment of hearing.
A condition in which the ossicles in the middle ear become thicker and the stapes becomes fixed to the oval window leading to deafness.
A type of ear and hearing problem in which one or more bones of the middle ear have excess bone and cannot therefore transmit sound vibrations effectively.
Hereditary condition in which ossification in the labyrinth of the inner ear causes tinnitus and eventually deafness. Surgery to remove the stapes (one of the middle ear bones) is usually successful.
Decreased function or mobility of bones of the inner ear and the oval window, causing conductive loss.
A disorder of the middle ear that causes progressive hearing loss, generally affecting both ears. The disorder results from changes in the composition of the stapes (the sound conducting bone in the inner ear). These changes cause the stapes, a normally movable bone in the middle ear, to become cemented to the surrounding bone and to stop vibrating; the vibrations conduct sound waves that are essential to hearing. Otosclerosis usually develops during the teen or early adult years.
A hereditary disorder causing deafness in adult life. An overgrowth of the bone of the inner ear leads to the third ear ossicle (the stapes) becoming fixed to the fenestra ovalis, which separates the middle and inner ears, so that sounds cannot be conducted to the inner ear. Deafness is progressive and may become very severe, but surgical treatment is highly effective.
Chronic progressive deafness, especially for low tones. It is caused by the formation of spongy bone, especially around the oval window, with resulting ankylosis of the stapes. In the late stages of this condition, atrophy of the organ of Corti may occur. The cause of this condition is unknown, but it may be familial. It is more common in women and may be made worse by pregnancy.
Growth of a spongy bone in the inner ear that results in gradual tinnitus, then deafness.
A condition characterized by the scarring and restriction of movement in the tiny auditory bones within the middle ear, leading to impaired mobility.
A middle ear disorder that leads to gradual hearing loss. Typically, this condition affects both ears.
Otosclerosis happens when excessive bone growth restricts the movement of the stapes, the smallest bone in the middle ear. Consequently, this inhibits the transmission of sound vibrations to the inner ear.
Otosclerosis commonly has a hereditary tendency, and its symptoms typically manifest in early adulthood. This condition is more prevalent among women than men and sometimes emerges during pregnancy.
For someone affected by this condition, sounds may appear muted, yet they can be discerned more readily in the presence of ambient noise.
The loss of hearing advances gradually over a span of 10 to 15 years and is frequently accompanied by tinnitus (a sensation of ringing in the ears) and, on rarer occasions, vertigo (a feeling of dizziness or spinning). A certain level of sensorineural deafness might manifest, making it challenging to perceive high-pitched sounds and leading to the individual speaking loudly.
The diagnosis of this condition involves conducting hearing tests. It can be effectively treated through a surgical technique known as stapedectomy, wherein a small piston replaces the immobilized stapes bone. This piston, passing through a hole made in the inner ear, can freely transmit sound vibrations to the inner ear. Another option for significant improvement in hearing is the use of a hearing aid.
A condition characterized by gradual hearing loss caused by abnormal bone growth within the auditory system, which disrupts the transmission of sound.
