It can be diagnosed incidentally by HRCT Anadolu Klin / Anatol Clin 157 Figure1. Pure tone audiogram: moderate-to-severe mixed type hearing loss in the right ear. Figure 2.

Preoperatively, these patients derived no benefits from hearing aids. Carhartz notch:- In pure tone audiogram bone conduction is normal but there is in bone conduction curve which is maximum at 2000 Hz, Called Carhartz notch and dip instead of deep. TREATMENT:- Medical:- Sodium fluoride used to hasten the maturity of active focus and arrest further cochlear loss. Cochlear implantation is rarely a treatment option and often comes only after unsuccessful otosclerosis surgeries. A cochlear implant (CI) is an electronic device that partly brings back sensorineural hearing loss.

Cochlea Redfishmedia. In the absence of cochlear involvement, the pure conductive hearing loss produced by the complete stapes fixation is limited to 60 to 65 dB, with a maximum air-bone gap across the frequency range.

There are 3 tiny bones … 1985-04-01 2012-07-02 2017-09-06 Introduction: Otosclerosis is a bone dysplasia of the optic capsule that promotes progressive metabolic derangement, and can lead to profound hearing loss. Aim: Compare the postoperative results in patients undergoing cochlear implant with otosclerosis compared with patients with other causes of deafness Design: Retrospective cohort study.. Materials and methods: Compare cochlear implant pathological condition of the bony labyrinth of the ear, in which there is formation of spongy bone; may cause bony ankylosis of the stapes, resulting in conductive hearing loss; cochlear otosclerosis may also develop, resulting in sensorineural hearing loss. Otosclerosis is a disease of the middle ear bones and sometimes the inner ear. Otosclerosis is a common cause of hearing impairment and is rarely hereditary.

1 It is an audiogram and the last available audiogram … In clinical practice, cochlear otosclerosis can also be observed. Audiologic rehabilitation of otosclerosis includes fitting of hearing aids and implantable hearing devices. Patients who underwent cochlear implantation after stapes surgery (10 per cent) also demonstrated a good audiological outcome.

Patients who underwent cochlear implantation after stapes surgery (10 per cent) also demonstrated a good audiological outcome. CONCLUSION: Stapes surgery is a suitable treatment option for patients with advanced otosclerosis, and should be considered mandatory, before offering cochlear implantation, for those with a demonstrable conductive component to their hearing loss.

Sometimes, in an audiogram with a drop in bone-conduction thresholds at 2 kHz, a “notch” is noted describing a decrease in cochlear sensitivity. – Describe the audiogram by configuration from least amount of hearing loss to the most (ex: mild to severe) – Pure tone average is 500 Hz, 1000 Hz, and 2000 Hz added and divided by 3. Degree of hearing loss Degree of hearing loss: • 0‐15 dB WNL • 16‐25 dB Slight • 26‐40 dB Mild In cochlear otosclerosis air conduction thresholds continue to worsen and the loss starts to become mixed or sensorineural, with the high frequencies becoming severely affected.
