In this paper the following aspects of otospongiosis will be discussed with data. ( A). Carhart's notch;. (B). Sensori-neural deafness in clinical otospongiosis;. (C).

Carhart’s notch was seen at 2 kHz in 28 (93 per cent) patients but at 1 kHz in only two (7 per cent). However, in patients with chronic otitis media, a Carhart’s notch was seen at 1 kHz in 10 (55 per cent) patients and at 2 kHz in eight (45 per cent) patients.

Carhart’s notch is classically seen as a dip centered around 2 kHz range of bone conduction curve audiometery.

Carharts notch

After successful stapes surgery the carharts notch disappears when the conductive hearing improves. This fact shows that carharts notch in no way represents sensorineural reserve of a patient. An audiometric finding characteristic of otosclerosis is an increase in bone conduction (BC) threshold with a peak at 2,000 Hz known as Carhart's notch (Carhart, 1950). Although the notch occurs at 2,000 Hz, a reduction in bone conduction sensitivity is seen from 500 to 4,000 Hz which is, on average, 5 dB at 500 Hz, 10 dB at 1000 Hz, 15 dB at 2000 Hz, and 5 dB at 4,000 Hz (Carhart, 1971).

The Carhart notch, an audiological finding mainly of historical importance, is a dip at 2000 hz in bone conduction without a corresponding dip in air conduction. The Carhart notch is often found in persons with conductive hearing loss, including "glue ear" (Kumar et al, 2003).

A Carhart's notch at 2 kHz indicates stapes footplate fixation, whereas one at 1 kHz indicates a mobile stapes footplate; the footplate mobility can thus be predicted pre-operatively.

Bone conduction is normal in otosclerosis. In some cases there is a dip in bone conduction curve which is maximum at 2000 Hz / 2 KHZ called as Carharts notch. Carhart's Notch Its Implications.

Jul 13, 2020 Loss is always greater at the frequencies 3000-6000 Hz than at 500-2000 Hz. Loss is usually greatest at 4000 Hz. The 4000-Hz notch is often Carhart's notch does not, however, truly represent a drop in cochlear sensitivity at 2000 Hz.

Otosclerosis is not typically illustrated by your loss: more often hearing losses present with a characteristic 2Khz dip (Carharts Notch).

As first described in 1950 by Raymond Carhart, the audiometric profile of classic otosclerosis presumes a "Carhart Notch" (CN) most likely to be found at 2000 Hz. Since that time, there have been multiple reports in the literature reporting CNs likely to be distributed between 500 and 2000 Hz. Perez et al (2009) revisited the issue in a retrospective analysis. They reviewed the records of 122

Bilateral otoskleros . Sänkningen av benledningen vid 1.5-2 kHz (Carhart's notch) är skenbar och den sensorineurala funktionen är i själva verket bättre än så. Det kan man registrera om man opererar och får ett maximalt lyckat operationsresultat.
