A conductive hearing loss is caused by any condition or disease that impedes the conveyance of sound in its mechanical form through the middle ear cavity to the inner ear. The reason for sensorineural hearing loss sometimes cannot be determined, it does not typically respond favorably to medical treatment, and it is typically described as an irreversible, permanent condition. A mixed hearing loss can be thought of as a sensorineural hearing loss with a conductive component overlaying all or part of the audiometric range tested. The conductive component may be amenable to medical treatment and reversal of the associated hearing loss, but the sensorineural component will most likely be permanent.
After initial hearing aid fitting, patients may find that it takes several weeks to adjust to the new hearing. If the hearing loss is profound, that is unaidable with a powerful hearing aid, then the patient may be a candidate for a cochlear implant. If you have any questions about Sensorineural Hearing Loss, treatment, billing, or insurance, please feel free to call Dr.
ENT Loyola UniversityIntroduction:The purpose of this paper is to familiarize audiologists with issues related to vertigo and sensorineural hearing loss, and the potential role of intratympanic therapy in treating specific disorders. Assorted Dizziness Statistics: 1) Dizziness is the most common reasons for a physician visit in patients over age 65 years. A conductive hearing loss can be the result of a blockage in the external ear canal or can be caused by any disorder that unfavorably effects the middle ear’s ability to transmit the mechanical energy to the stapes footplate. Generally, the cause of conductive hearing loss can be identified and treated resulting in a complete or partial improvement in hearing.
The sensory component may be from damage to the organ of Corti, an inability of the hair cells to stimulate the nerves of hearing or a metabolic problem in the fluids of the inner ear. Like conductive hearing loss, sensorineural hearing loss reduces the intensity of sound, but it might also introduce an element of distortion into what is heard resulting in sounds being unclear even when they are loud enough. So, in addition to some irreversible hearing loss caused by an inner ear or auditory nerve disorder, there is also a dysfunction of the middle ear mechanism that makes the hearing worse than the sensorineural loss alone.


Hearing aids can be beneficial for individuals with a mixed hearing loss, but caution must be exercised by the hearing care professional if the conductive component is due to an active ear infection. Sounds waves may travel through the ear but this nerve pathway is unable to send electrical impulses to the brain. The type of hearing aid in terms of power, size, options, and costs are best determined by you and your audiologist. Moreover, with the small discreet hearing aids available today, one is more likely to lose them in their pockets or in the bureau drawer. This surgical implanted device bypasses the nerve endings to stimulate directly the auditory nerve fibers to give hearing. The theory behind intratympanic therapy is that by instilling small amounts (<5 cc) of medication into the middle ear, absorption into the inner ear occurs though the round window. 2) Thirty percent of the population will experience vertigo by the age of 65 3) Ninety million Americans will experience dizziness or vertigo during their lives.
Following the completion of medical treatment for causes of the conductive hearing loss, hearing aids are effective in correcting the remaining hearing loss. The neural or retrocochlear component can be the result of severe damage to the organ of Corti that causes the nerves of hearing to degenerate or it can be an inability of the hearing nerves themselves to convey neuro chemical information through the central auditory pathways.
Once any medically treatable conditions have been ruled out, individuals with a sensorineural hearing loss can be fit with hearing aids to give them access to speech and other important sounds. Your (otologist) physician’s job is to try to establish the cause of your sensorineural hearing loss which then determines its treatment.
Very mild hearing loss may be best managed with Assistive Listening Devices (ALD) and strategic optimization of the listening environment when possible. Vertigo is more specific and refers to a sensation of movement (usually spinning) of the individual or their surrounding.
Benign Positional Paroxysmal Vertigo (BPPV): The most common cause of vertigo is Benign Positional Paroxysmal Vertigo (BPPV).


If the hearing aids are adjustable with hand controls, it may take a few weeks until sufficient dexterity and familiarity with these controls are achieved.
Dizziness can be secondary to neurological, cardiac, metabolic, psychiatric, vestibular, or other disorders. This is characterized by a sensation of spinning lasting only several seconds that occurs with quick movements of the head such as rolling over in bed, looking up, or looking down. BPPV is believed to occur secondary to free floating otoconia (calcium carbonate crystals normally within the utricle and saccule) that break loose (spontaneously, or through trauma) and attach to, or cause stimulation of, the posterior semicircular canal with movement of the head. Many cases resolve spontaneously while others are treated with various particle - repositioning maneuvers. Advances in hearing aid technology and cochlear implants are helping to improve communication for people affected by hearing loss.
You will be asked about other medical conditions and about what over-the-counter and prescription medications you take. You may be asked to cover one ear at a time while listening to sounds at different volumes.
Tests using a tuning fork can check if there is damage to the parts of the middle ear and eardrum that vibrate. However, the doctor will try to identify the cause of your hearing loss before treatment can begin.
