Traumatic perforation: determinants of conductive hearing loss
. Int J Otorhinolaryngol Head Neck Surg.
In these evaluations it is necessary to verify if there is auditory alteration, the type of alteration and the degree of the same, being indispensable to differentiate conductive hearing losses
of sensorineural and to determine the thresholds by air and bone pathways.
Hearing loss as confirmed by PTA was found in 89 Percent of otological trauma with 76 cases of conductive hearing loss
, 18 with pure sensory neural and 27 with mixed deafness.
In those patients with conductive hearing loss
, an ossicular abnormality has been shown on only three occasions .
RELATIONSHIP BETWEEN RME & CONDUCTIVE HEARING LOSS
All patients fulfilling the inclusion criteria of being indigenous black South Africans with progressive painless conductive hearing loss
without infection or trauma, normal tympanic membrane and the presence of a Carhart notch on the audiogram, were included.
Otitis media is a conductive hearing loss
that is more prevalent in Aboriginal than non Aboriginal communities, with reports suggesting that up to 70% of Aboriginal children could be affected (Couzos, Metcalf and Murray 2001, cited in Partington and Galloway 2005, p.
Hearing impairment due to conductive hearing loss
can have a devastating effect on children's language development, and consequently educational outcomes, especially for Indigenous students, for whom there may be the additional issue of being educated in their second or third language.
BAHA are surgically implanted into patients who have nerve end conductive hearing loss
, which can be caused by chronic ear infections.
During the conference the newly formed group introduced the SMartTM prosthesis product for surgical correction of conductive hearing loss
When hearing loss is caused by a physical problem in the external ear or in the middle ear, it is referred to as a conductive hearing loss
. Sensorineural hearing loss occurs when a sound is conducted normally from the exterior ear through the eardrum to the middle ear, but the inner ear does not transmit the sound normally to the brain.
Otosclerosis usually causes a conductive hearing loss
, a hearing loss caused by a problem in the outer or middle ear.
