Unilateral hearing loss is a special case of hearing loss. For hearing aids for patients with unilateral hearing loss, there are some very noteworthy places!
First, unilateral suppurative otitis media:
Suppurative otitis media is usually caused by a cold or other respiratory infection causing bacteria entering the middle ear cavity through the eustachian tube. The disease may be acute (severe but short duration) or chronic (long duration).
Suppurative otitis media in one ear causes a more severe hearing loss, starting with a simple conductive hearing loss, but as the disease progresses, the inflammation gradually affects the cochlea and then gradually develops a sensory change, which may eventually develop into a severe or even severe mixed hearing. loss.
Due to the asymmetrical hearing of the ears, there is a bone conduction defect in the affected ear, and gas bone conduction masking is needed in pure tone audiometry. For more serious conditions, care should be taken to avoid excessive masking.
Usually suppurative otitis media should avoid wearing hearing aids. However, if surgery and medical treatment have basically dried the ear, you should consider the choice of hearing aids as early as possible to establish a balance of binaural hearing function.
It is emphasized here that during the wearing of the hearing aid, it is necessary to go to the hospital to follow the middle ear condition frequently, and if necessary, preventive drops should be taken to maintain the dry ear state.
Second, unilateral sensory hearing loss:
Unilateral sensorineural hearing loss is severe and lasts for a long time (up to several decades). There are many causes, such as mumps or abruptness in childhood. Most patients find themselves when using a phone or earphone. One ear can’t hear the sound.
Poor ear hearing ability, listening almost completely rely on better ears, so better ears due to long-term listening and excessive fatigue, resulting in secondary sexy hearing loss. These patients areHearing lossTinnitus often occurs before, and hearing loss occurs after a long period of tinnitus.
Third, asymmetric sensory hearing loss:
This type of patient may initially have a unilateral sensorineural hearing loss, but did not wear the hearing aid in time, and decided to have hearing loss in the ear when the hearing aid was fitted. It may also be bilateral hearing loss, and the hearing loss on one side is severe and the appearance time is long. The other side of the ear has a lower degree of hearing loss and a shorter appearance time.
In the face of such hearing loss, the fitter often chooses to use a hearing aid for better ear detection. The initial listening effect is better and the success rate of the fitting is also high. However, after the follow-up, it is found that the ear wearing the hearing aid is unstable in hearing, and Tinnitus often occurs, the hearing function of the ears is severely unbalanced, and even the hearing of the good ears is getting worse.
This may be due to the increased hearing burden of the ear after wearing the hearing aid, making it overworked and causing hearing loss.
If the hearing aid is fitted to a poor ear, the initial listening effect may be very poor, and the situation may be “audible but inaudible”, but after wearing for a period of time, the tinnitus of the better ear will weaken or even disappear, and the long-term wear will be maintained. And rehabilitation training, hearing of both ears have different degrees of response, speech resolution is significantly improved.
In summary, unilateral deafness must establish a balanced binaural hearing function as early as possible. As soon as possible, hearing aids for patients with unilateral hearing loss can avoid or slow down the hearing loss of better ears. At the same time, the poor ear can be exercised through moderate sound stimulation, and the potential auditory function is restored to some extent.
