The shape of the plot reveals the degree and nature of hearing loss, distinguishing conductive hearing loss from other kinds of hearing loss. A conductive hearing loss is characterized by a difference of at least 15 decibels between the air conduction threshold and bone conduction threshold at the same frequency. On an audiogram, the "x ...
PTA can be used to differentiate between conductive hearing loss, sensorineural hearing loss and mixed hearing loss. A hearing loss can be described by its degree i.e. mild, moderate, severe or profound, or by its shape i.e. high frequency or sloping, low frequency or rising, notched, U-shaped or 'cookie-bite', peaked or flat.
Air conduction: Sound propagated from a sound source through the air is received by the outer ear, and then transmitted via the ear drum, middle ear, and inner ear. Bone conduction: Sound from a vibrator oscillates the skull bone, and the vibration is transmitted directly to the inner ear without passing through the ear drum and middle ear.
Hearing loss that results from changes in the middle ear is called conductive hearing loss. The middle ear contains three tiny bones that help transfer sound from the eardrum to the inner ear. Some forms of nonsyndromic deafness involve changes in both the inner ear and the middle ear; this combination is called mixed hearing loss.
Conductive deafness-ptosis-skeletal anomalies syndrome, also known as Jackson Barr syndrome, [1] is a rare presumably autosomal recessive genetic disorder characterized by conductive hearing loss associated with external auditory canal-middle ear atresia which aggravates during ear infections, ptosis, and skeletal anomalies which consist of clinodactyly of the fifth fingers, radial head ...
A bone-anchored hearing aid (BAHA) [2] is a type of hearing aid based on bone conduction.It is primarily suited for people who have conductive hearing losses, unilateral hearing loss, single-sided deafness and people with mixed hearing losses who cannot otherwise wear 'in the ear' or 'behind the ear' hearing aids.
Conductive hearing loss may also result from middle ear inflammation causing fluid build-up in the normally air-filled space, such as by otitis media. Tympanoplasty is the general name of the operation to repair the middle ear's eardrum and ossicles.
The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
