summary

Otosclerosis is a disease of unknown origin. Pathologically, it is due to the primary localized bone resorption in the bone labyrinth, which is replaced by spongy bone hyperplasia with abundant blood vessels, so it is called "sclerosis". When invading the oval window, it can cause stapes fixation, loss of sound transmission function and progressive hearing loss. Common symptoms of otosclerosis include? Let's talk about it

Common symptoms of otosclerosis include?

Deafness: bilateral or unilateral progressive hearing loss is the main symptom of the disease. Tinnitus: about 20% - 80% of patients have tinnitus. Tinnitus is mostly low-frequency, persistent or intermittent, and high-frequency tinnitus may appear later.

Wechsler's false hearing phenomenon: it is difficult for patients to distinguish speech in general environment, but their ability to distinguish speech is improved in noisy environment. This phenomenon is called Wechsler's false hearing. Vertigo: a small number of patients have transient mild vertigo during head movement.

In the early stage, the hearing loss was characterized by low-frequency decline, flat curve in the middle stage, Carhart notch (y notch) in the bone conduction curve, and mixed hearing loss in the late stage. Gelle's test was negative. Acoustic impedance audiometry showed that the sound order decreased, the tympanometric curve was as type, and the stapes reflex disappeared.

matters needing attention

Surgical treatment is the most effective measure to improve hearing. Stapes shaking has a good short-term effect, but the source of sclerosis can not be controlled, and the long-term effect is poor. Fenestration of the inner ear can also improve hearing, but the long-term effect is poor, which may lead to sensorineural hearing loss. At present, partial or total removal of stapes is commonly used, and then artificial stapes is installed. The operation is carried out under the microscope, which requires certain equipment conditions and technical level.
