Otosclerosis presents in a unique and typical way. Pure stapedial otosclerosis has its unique signature which can be recognized on pure tone and impedance audiometry. Otosclerosis audiogram The audiogram with worse air-conduction thresholds at low frequencies, below 1-2 kHz, is typical for otosclerosis 1). Sometimes, in an audiogram with a drop in bone-conduction thresholds at 2 kHz, a “notch” is noted describing a decrease in cochlear sensitivity. Otosclerosis is a common condition affecting the bone of the otic capsule in 7.3% of Caucasian males and 10.3% of Caucasian females. The condition is rare in non-Caucasians, except East Indians, in whom the incidence is approximately the same as pers 1226 AudiologyOnline Article Otosclerosis, also known as otospongiosis, is a primary osteodystrophy of the otic capsule (bony labyrinth of the inner ear). It is one of the leading causes of deafness in adults.

(B) Pure tone audiogram of a patient who has a central perforation. There is no notch at 2000 Hz. (Adapted from Beales, PH. Otosclerosis . Bristol; John Wright and Sons: 1981. Used with permission.) Carhart’s notch is thought to be typical of otosclerosis (Carhart 1950, 1962). Otosclerosis audiogram The audiogram with worse air-conduction thresholds at low frequencies, below 1-2 kHz, is typical for otosclerosis 1) . Sometimes, in an audiogram with a drop in bone-conduction thresholds at 2 kHz, a “notch” is noted describing a decrease in cochlear sensitivity. 2014-02-25 The first step in a diagnosis is to rule out other diseases or health problems that can cause the same symptoms as otosclerosis.

If an Audiogram results in the hearing threshold greater than 25 dB, then it is abnormal.

Meniere’s disease B. Otitis media with effusion C. TM perforation D. Otosclerosis Question 3:Based on this audiogram and knowing the patient had Ett audiogram, då man får lyssna på toner i hörlurar och markera vilka man hör, kan också visa förändringar som talar för otoskleros. Om det finns misstanke om otoskleros remitteras man till en öron-näsa-hals specialist som kan genomföra ytterligare undersökningar för att fastställa diagnosen. 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. 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).
