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. Characteristic abnormalities appear on tympanometry, acoustic reflexes, and the pure-tone audiogram.

Audiometric data usually demonstrate a conductive hearing loss at the early stages of otosclerosis. Modern middle ear analysis procedures are becoming more popular in the better diagnosis of otosclerosis. Otosclerosis cannot be seen on an office examination. The audiogram indicates a conductive type of hearing loss. A special type of testing, stapedial reflexes, indicates limited or no movement of the bones of hearing. Otosclerosis usually causes conductive hearing loss, which means there is a problem with how the ear transmits sound vibrations.

Otosclerosis usually causes conductive hearing loss, which means there is a problem with how the ear transmits sound vibrations. In a normal ear, sound vibrations are funneled by the outer ear onto the ear drum, or “tympanic membrane.” 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. #carhart #notch #otospongiosisDip at 2000Hz Bone Conduction frequencyPlaylist https://www.youtube.com/playlist?list=PLKKWBex6QaMCojCF2tDToiD-nNhVZbIyO A Brigham and Women’s Hospital otolaryngologist will first conduct a thorough medical history and physical examination to rule out other diseases or health problems that can cause the same symptoms as otosclerosis. Next steps will include hearing tests that measure hearing sensitivity (audiogram) and middle-ear sound conduction (tympanogram). Audiograms, in addition to medical history and physical examination, have traditionally been used for diagnosis of otosclerosis.

Audiograms, in addition to medical history and physical examination, have traditionally been used for diagnosis of otosclerosis. 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.

The Carhart notch is a depression in the bone-conduction audiogram of patients with clinical otosclerosis. The middle frequencies from 0.5 to 2 kHz, which correspond to the resonance frequency of the middle ear, can be substantially improved following successful stapes surgery.

Otosclerosis is a condition in which there's abnormal bone growth inside the ear. It's a fairly common cause of hearing loss in young adults. There are 3 tiny bones deep inside the ear that vibrate when sound waves enter. They transmit sound waves to the cochlea (inner ear), which converts them into signals that are sent to the brain.
