Carhart’s notch is a mechanical artifact and is not a true representation of cochlear reserve. Evidence that the Carhart’s notch is an artifact is seen in overclosure following stapes surgery.

Treatment There is no known procedure to prevent the bone remodeling process itself. Objective: The hallmark of bone conduction audiometry in otosclerosis is the "Carhart notch."The mechanism for this phenomenon is still not clearly understood. The objective of this study was to describe the pattern of bone-conduction threshold responses preoperatively in patients with otosclerosis and to assess overclosure after laser-assisted stapedotomy.

Popular version of paper 4aPPa2 2013-08-05 Otosclerosis is a condition of the inner ear where one or more foci of irregularly laid spongy bone replace part of normally dense enchondral layer of bony otic capsule in the bony labyrinth.This condition affects one of the ossicles (the stapes) resulting in hearing loss, tinnitus, vertigo or a combination of symptoms. The term otosclerosis is something of a misnomer.

(1) The presence of a refraction of the bone conduction curve with a depth of 10 to 20 dB at a frequency of 2000 Hz (the so-called Carhart notch) in the presurgical tonal audiogram is an unfavorable prognostic factor in relation to closing the cochlear reserve and improving bone conduction after the stapedotomy. 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. 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).
