Despite the discomfort that hearing loss might cause, there are strategies to manage the illness through therapy and avoidance. Hearing aids Singapore are one of the ways to relieve the discomfort caused by poor hearing.
People of all ages can experience hearing loss when one or more earpieces are problematic. But it helps to have a fundamental understanding of normal function to comprehend the reasons for hearing loss.
Sound waves that pass through the external ear canal cause the eardrum to vibrate in air conduction. Three tiny bones (ossicles) in the middle ear carry the eardrum’s vibration to the hearing organ’s cochlea. This activates the cochlea’s sensory cells, which subsequently transmit signals to the hearing nerve (also known as the auditory nerve) and the brain.
When sound waves force the skull’s bones to vibrate, the cochlea (the hearing organ) is directly stimulated, producing hearing by bone conduction.
Causes of Hearing Loss
There are two distinct forms of hearing loss, and their causes might vary.
Conductive Hearing Loss
When sound waves from the environment beyond the cochlea are not effectively transferred, conductive hearing loss results. The outer ear canal, eardrum, middle ear bones, or middle ear space may all be the source of the issue. The following are typical causes of conductive hearing loss:
- Wax, a foreign object, or infection are the three common causes of external ear canal obstruction (otitis externa).
- Perforated eardrum: Usually caused by injury or persistent illness.
- Ossicles (malleus, incus, or stapes) that have been dislocated, injured or corrected due to trauma, long-term conditions that erode the ossicles over time, or otosclerosis.
- An otitis media infection typically involves fluid in the middle ear space.
Sensorineural Hearing Loss
When the cochlea or hearing nerve is damaged, sensorineural hearing loss results (auditory nerve). Typical reasons include
- Ageing (presbycusis) (presbycusis)
- The sensory cells in the cochlea may get damaged after both short-term and long-term exposure to loud noise.
- infections of the inner ear caused by bacteria and viruses such the measles, mumps, and influenza
- A condition known as Ménière illness causes tinnitus, hearing loss, and vertigo.
- Acoustic neuroma: a vestibular nerve tumour that interferes with the function of the auditory nerve by growing near to it.
- Medicines that cause hearing loss or damage to the cochlea’s sensory cells are known as ototoxic drugs. Examples comprise:
- Various antibiotics, such as aminoglycosides (gentamicin, vancomycin)
- Frusemide is one kind of diuretic.
- Antineoplastics (cancer medicines) (cancer drugs)
Hearing Loss Symptoms
Hearing loss may affect one or both ears, which can be progressive or abrupt.
The affected person typically laments their inability to carry on a regular conversation, especially in loud settings. Others may have complained that the person speaks more vociferous than usual or does not answer when called.
There could be accompanying signs like vertigo or tinnitus (ear ringing) (spinning sensation).
Ear infections can come with pain and ear discharge.
How to Prevent Hearing Loss
The hearing loss brought on by noise is often permanent and worsens with each exposure. When working near loud noises, especially for extended durations, those who operate heavy machinery or work in the construction business should wear the appropriate ear protection. To ensure that their hearing is not worsening, they should also get frequent hearing exams. Children shouldn’t go to discos or wear headphones.
Hearing tests and the diagnosis of hearing loss
A thorough history, an ENT exam, and proper investigations are required for a diagnosis. The ENT doctor will thoroughly examine your head and neck, particularly your ear canal and tympanic membrane. It is also essential to do an endoscopic examination of the nose and nasopharynx. A neurologic examination will occasionally be performed.
An audiogram will be taken to establish the existence of hearing loss and determine its kind and severity. Tympanograms can also find issues with the middle ear and eardrum. An auditory neuroma may be found via radiological imaging techniques like CT scans or MRIs (magnetic resonance imaging).
Options for Treating Hearing Loss
Health Care for Hearing Loss
The underlying issue determines the course of medical treatment. Treatment options may include monitoring and assurance of drugs and discussing possible surgical procedures. The ENT surgeon can remove the wax and foreign substance in the ear canal under a microscope if it is the source of the hearing loss.
There is a requirement for a topical antibiotic in situations of external ear infections. The underlying condition has to be addressed if the eardrum is perforated. If the ear perforation persists for more than three months or there is an issue with recurring ear infections with ear discharge, surgical correction of the ear perforation may be required.
Presbycusis (old age-related hearing loss) does not require treatment. However, the affected person will be counselled on safeguarding his hearing and assessed to see whether hearing aid assistance is necessary.
Hearing Aids Singapore
Typical hearing aids are amplification devices that pick up on ambient noise and present and magnify it for the external ear canal. Both conductive and sensorineural hearing loss might benefit from them. Modern Hearing aids Singapore range in size from tiny, totally in-canal devices to the more conventional behind-the-ear devices. To get the best possible sound, a qualified audiologist will assist in customising the hearing aid.
Occlusion effect, feedback, and an increased risk of ear infections are some of the negative impacts of hearing aids.
Hearing Implants
Technology advancements have led to the creation of hearing implants. There are primarily two categories of surgical implants. People who have tried hearing aids but cannot use them or do not benefit from them are treated with middle ear implants. Both conductive and sensorineural hearing loss can be treated with it. It consists of a transducer directly attached to the spherical window or the ossicles (part of the cochlea). It causes the middle ear components to vibrate and increases sound transmission.
Cochlear implants are employed when a person has moderate to severe sensorineural hearing loss. To get around any cochlea issues, the ENT surgeon will place the electrical electrode of the implant directly into the cochlea and activate the cochlea’s nerve endings there. Adults and children both utilise cochlear implants.
Summary
People of all ages can experience hearing loss when one or more earpieces are problematic. There are two distinct forms of hearing loss, and their causes might vary. The outer ear canal, eardrum, middle ear bones, or middle ear space may all be the source. Hearing loss brought on by noise is often permanent and worsens with each exposure.
