DOI: 10.1016/j.otc.2017.11.007 Abstract Diagnostic audiologic procedures for otosclerosis are effective tools in identifying this condition. Audiometric data usually demonstrate a conductive hearing loss at the early stages of otosclerosis.
Carhart notch and electric bone-conduction audiometry
https://pubmed.ncbi.nlm.nih.gov/8085115/
The Carhart notch is a depression in the bone-conduction audiogram of patients with clinical otosclerosis. The middle frequencies from 0.5 to 2 kHz, which correspond to the resonance frequency of the middle ear, can be substantially improved following successful stapes surgery. Twenty-nine consecuti …

The first step in a diagnosis is to rule out other diseases or health problems that can cause the same symptoms as otosclerosis. Next steps include hearing tests that measure hearing sensitivity (audiogram) and middle-ear sound conduction (tympanogram). Sometimes, imaging tests—such as a CT scan—are also used to diagnose otosclerosis.

Los siguientes pasos incluyen pruebas de audición que miden la sensibilidad auditiva (audiograma) y la conducción del sonido en el oído medio (timpanograma). A veces, también se utilizan imágenes diagnósticas, como una tomografía computarizada (computed tomography scan, CT scan) para el diagnóstico de la otosclerosis.

The term cochlear otosclerosis is used to describe the sensorineural hearing loss seen in some patients with otosclerosis. This process can result in profound sensorineural hearing loss. Photo One shows the CT of a normal cochlea. Photo Two shows the temporal bone CT of a woman with bilateral profound sensorineural hearing loss due to otosclerosis.
