otosclerosis surgery after partial stapedectomy, total stapedectomy and pattern of the cochlea. The typical pattern of cochlear otosclerosis in the early stages is the “cookie bite” pattern , where the greatest degree of hearing loss occurs in the midfrequency hearing range and is characteristically a mixed hearing loss (Hannley 1993). Tinnitus is usually present in a large percentage of patients. When pure stapedial otosclerosis is present, the most prominent audiologic signs are elicited in response to the use of low-frequency stimuli, reflecting the effect that increased stiffness has on the transfer function of the middle ear.

4 • Otic capsule The embryonic cartilage capsule that surrounds the inner ear mechanism and develops into bony tissue. 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. The audiological signature pattern of fenestral otosclerosis include the following: Conductive hearing loss with Carhart’s notch at 2KHz. Excellent speech discrimination scores (Also seen in cochlear otosclerosis) Low compliance on Impedance (immitance) audiometry (less than 0.3cc) Seen in fenestral as well as cochlear otosclerosis. 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 resulting in hearing loss, tinnitus, vertigo or a combination of symptoms.

On audiometry, the hearing loss is characteristically low-frequency, with higher frequencies being affected later.

Otosclerosis is a disorder of bone that affects human beings only and involves the otic capsule (bony labyrinth) and primarily the stapes bone of the middle ear. It is the slow progressive fixation of the stapes bone in the oval window which usually causes the clinical symptoms to become noticed in the form of a conductive hearing loss.

The prosthesis preferred at the Tampa Bay Hearing and Balance Center is a cup shaped prosthesis. On audiometry, the hearing loss is characteristically low-frequency, with higher frequencies being affected later. Sensorineural hearing loss (SNHL) has also been noted in patients with otosclerosis; this is usually a high-frequency loss, and usually manifests late in the disease.

otosclerosis audiological findings: audiogram the first affect of otosclerosis: conductive loss below 1kHz progression to the cochlea may result in increased bone conduction thresholds- high frequencies affected because the disease is usually adjacent to the basal turn of the cochlea

These patterns can extend to the associated immit-tance and speech testing. For example, patients with otosclerosis will have a conductive hearing loss noted in the involved ear.

An audiogram and tympanogram can be used by an audiologist or otologist to determine the degree of hearing sensitivity and conductivity. A CT scan can give a definitive diagnosis of otosclerosis by showing the level of bone overgrowth which would differentiate this disorder from other causes of hearing loss.

17 An audiogram measures air and bone conductions and interactions throughout various frequencies (Hz) at various loudness levels (dB). An audiogram that results in hearing thresholds greater than 25 dB is abnormal. Pattern recognition can also help guide inter-pretation of the remainder of the audiogram data. These patterns can extend to the associated immit-tance and speech testing. For example, patients with otosclerosis will have a conductive hearing loss noted in the involved ear.
