PubMed comprises more than 26 million citations for biomedical literature from MEDLINE, life science journals, and online books.

An audiometric finding characteristic of otosclerosis is an increase in bone conduction 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).

Quinn Jr. MD FACS SERIES EDITORS Francis B. … 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.

2013-05-17 · This produces a characteristic loss in bone-conducted (BC) hearing of about 20 dB between 1 and 2 kHz, known as "Carhart's notch", for which the specific mechanisms responsible have not yet been well understood.

Sänkningen av benledningen vid 1.5-2 kHz (Carhart's notch) är skenbar och den sensorineurala funktionen är i själva verket bättre än så.

Delayed facial paralysis following uneventful KTP laser stapedotomy: two case reports and a review of the literature 2013-05-17 2011-03-21 Otosclerosis results in an audiogram with significant loss at all frequencies, often of around 40 dB(HL). A deficiency particularly around 2 kHz (termed a Carhart notch in the audiogram) is characteristic of either otosclerosis or a congenital ossicular anomaly.. Ménière's disease results in a severe loss at low frequencies.. Noise induced deafness or sensorineural loss results in loss at 2020-02-16 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. 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. This article discusses the reason for the presence of carhart's notch in the bone conduction audiogram of patients with otosclerosis 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.
