Why one ear does not hear well, the reasons for the declinehearing in adults and children

Update: October 2018

Hearing is an important tool for connecting a person to the outside world. With
impaired hearing capacity is reduced load on the brain

learning).

In addition, reduced hearing causes problems when communicating with others.

consultation to the otolaryngologist (ENT specialist).

Hearing loss is otherwise called hearing loss. condition
differentiated by degrees, depending on how far
man hears spoken language.

Degree of hearing loss

Threshold of sound perception Distance of speaking
Easy – 1 degree 26-40 decibel 4-6 meters
Medium – 2 degree 41-55 decibel 1-4 meters
Heavy – 3 degree 56-70 decibel 0.25-1 meter
Deep hearing loss – grade 4 71-90 decibel
Deafness > 91 децибелла

Why hearing is reduced

About 8% of the world’s population has hearing problems, in fact
In fact, this figure is underestimated. Since not everyone treats this
problem to specialists. Men suffer from hearing loss more often.

after 50 years.

The organs of hearing are represented by:

  • peripheral part (outer, middle ear), conducting
    sound
  • sensory epithelium of the inner ear, perceiving the signal
  • auditory nerve transmitting impulse
  • and the central part analyzing the incoming information
    (cortical analyzer or part of the cerebral cortex in the temporal
    lobe).

Hearing loss may be due to damage or
diseases of any part of the auditory pathway. In addition, frequent

Conductive hearing loss

and middle ear, talk about conductive hearing loss.

  • External auditory canal can be closed by sulfur plugs.

Sulfur is the natural secret of the outer ear, which when bad
hygienic care, frequent inflammatory diseases of the ears or
mechanical stimulations of the ear can accumulate in the form of dense

  • Otitis

Middle catarrhal or purulent otitis media (inflammation of the middle ear)
due to effusion can significantly reduce hearing with both one and
two sides (see otitis symptoms in children). If on the drum
membrane opens the abscess, and a hole is formed, then to
the moment of its healing or operative recovery, hearing can
completely absent on one or both ears. If healing
eardrum will occur with the formation of a large or coarse
then it will cause a persistent hearing loss on
affected ear.

  • Mechanical injury of the eardrum

This is the result of mindless tinkering in the ears. Barotrauma this

Most often, it is received by those who are struck on the ear, hunters,
who shot over the ear, as well as divers – losers.

  • The furuncles of the auditory canal with significant size and due to
    swelling can also lower hearing.

Neurosensory causes

Sensorineural or neurosensory hearing loss – consequence
problems with the host: inner ear, 8 pair
cranial nerve or cortical and
stem centers of the auditory analyzer.

Congenital variants of neurosensory hearing loss – they are most often
appear with underdeveloped sensory epithelium of the inner ear.

Congenital hearing loss in a child

  • With внутриутробном заражении краснухой ребенок может родиться с
    Greg’s triad (deafness, heart disease and eye damage).
  • Fetal syphilis also leads to deafness.
  • Vertical infection with chlamydia during childbirth can be
    cause of hearing loss in the newborn.
  • Deep prematurity (up to 32 weeks) does not allow
    neurosensory apparatus to develop and leads to hearing loss.
  • In alcoholic mothers and drug addicts because of ototoxic
    actions taken substances children are often born with reduced
    by hearing.
  • Congenital Inherited Malformations – Snail Aplasia and
    Labyrinth: Mondini Shaybe, Michael, – causes of congenital deafness.
    Syndromes of Gervella (hearing loss and heart disease), Pendred
    (hyperplasia of the thyroid gland and deafness), Ushera (retinitis and
    hearing loss), Wardenburg (eyes of different colors, accrete eyebrows,
    gray strand over forehead and hearing loss), Stickler (strong myopia,
    gothic sky, early cataract, hearing impairment) – also
    hereditary congenital diseases.
  • Children with Down syndrome are often deaf already from
    of birth.

Sensorineural hearing loss

Neurosensory hearing loss can be purchased in children’s or
adulthood. In the first place of its causes – hygiene violations

    ведет к нарушению восприятия soundов высокой частоты.
  • Elderly people suffer from presbyacusis, that is, degeneration

  • The abuse of headphones affects the auditory nerves and is known
    as the “telephone operator disease”. Pathology is associated with a violation
    myelin sheath of the auditory nerve. It is actually chronic.

  • Низкие частоты восприятия soundов выпадают при болезни Меньера,
    accompanied by frequent systemic vertigo and loss
    equilibrium, hearing loss and tinnitus.
  • Traumatic injuries of the temporal bone, snail. 8 pairs
    cranial nerves, cerebral cortex in the auditory centers can
    cause a secondary neurosensory hearing loss with one or
    both sides.
  • Viral infectious diseases (measles, mumps,
    herpes, rubella. flu) can damage the auditory nerves.
  • Bacterial lesions of the maze, temporal bone, Eustachian
    tubes or meninges lead to hearing loss or deafness.
  • Autoimmune diseases (eg, Wegener’s granulomatosis)
    become the primary cause of otosclerosis and hearing loss.
  • Chronic allergic rhinitis causes catarrhal
    chronic otitis, which often leads to hearing loss in children
    age
  • Otosclerosis or growth of bone and connective tissue in

  • Tumors of the pre-vesicular nerve (neuroma), neoplasm
    pectoralis or brain meninges can lead to

A variety of drugs have an ototoxic effect.

  • Aminoglycosides (kanamycin, gentamicin, streptomycin, amikacin)
    особенно в сочетаниях с фуросемидом дают снижения hearing
  • The diuretics themselves are, like the macrolide antibiotics
    (josamycin, azithromycin), nonsteroidal anti-inflammatory may
    cause reversible hearing loss after abolition
    drugs.

Hearing loss on the background of circulatory disorders

Often to neurologists, in addition to complaints of pain in the head or neck, noise
in the ears and ringing in the temples, sleep and memory disorders can be heard
from patients: “I hear badly with one ear”. A patient with similar
complaints, in addition to a routine inspection of the ENT is shown more in-depth
examination of neck vessels (USDG) and spinal images in two
projections.

Correction of neurosensory hearing loss

Only the acute form of neurosensory can be cured completely.

understand the hearing loss that developed acutely within 72 hours and
affected one or both ears. Often patients complain: “I hear badly
after a cold. ”

Although up to two thirds of patients can continue to receive
improvement without therapy, otolaryngologists consider waiting
tactics wrong. With этом с самых первых дней лечения

    hearing loss on the background of circulatory disorders (strokes).
  • With болезни Меньера эффективными бывают Бетасерк и Идебенон, а
    also diuretic, reducing the number of endolymph in the cochlea.
  • With хронических формах тугоухости наиболее часто приходится
    resort to hearing aids. In first place today especially in
    children’s practice go cochlear implants – hearing aids,
    which can be installed inside the ear for constant wear. They have
    small size, do not cause discomfort and directly stimulate
    auditory nerve.
  • Hearing aids of various modifications from ear to ear
    require individual selection and a certain time for
    addictive. Many patients, especially older ones, refuse
    hearing aids due to poor device selection and
    inconvenience when wearing it.

Alternative ways to restore hearing

  • Massage auricles can improve blood flow
    inner ear and cerebral cortex. Its variety is
    acupuncture massage or qigong techniques borrowed from
    Chinese medicine. ATспомогательное средство. Which by itself
    does not solve the problem.
  • Microcurrent reflexology – physiotherapy, not decisive

  • Методика М. Норбекова с произношением согласных soundов,
    pushed from the oropharynx into the ear, as well as training with
    soundовоспроизводящими устройствами – невредное развлечение на этапе
    self-study. From the moment of attraction to the paid courses –
    sectarianism, harmful to health and pocket.

Thus, hearing loss is a serious problem with which
