Profound sensori – Neural hearing loss


Severe-to-profound hearing loss has significant impact on children and adults, with respect to their daily lives. Hearing loss can be inherited. It can cause mild to profound sensori-neural hearing loss. Disease like mumps may result in profound sensori-neural hearing loss unilaterally or bilaterally. Profound hearing loss is generally known as deafness. Hearing aids may not be beneficial for particular patients with severe and profound sensorineural hearing loss. Appropriate management uses cochlear implants in individuals with profound sensori-neural hearing loss.

Unilateral sensorineural hearing loss


Unilateral hearing loss or single-sided deafness is a type of hearing impairment where there is normal hearing in one ear and impaired hearing in the other ear. Known causes include physical trauma, acoustic neuroma, measles, microtia, meningitis, Ménière's disease, mumps or Mastoid infection. Foreign bodies in the external auditory canal or congenital cholesteatoma also can cause unilateral conductive hearing loss. Temporal bone fractures can also cause unilateral hearing loss. Profound unilateral hearing loss is a specific type of hearing impairment when one ear has no functional hearing ability. The hearing in background noise will be difficult in this condition.

Sudden Sensorineural Hearing Loss


It involves rapid loss of hearing. SSHL can happen to a person all at once or over a period of up to 3 days. It should be considered a medical emergency. Sudden hearing loss in one ear is the commonest case. Some patients show spontaneous recovery. SHL can affect different people very differently. Sudden deafness in one ear is often accompanied by tinnitus, vertigo or both. Sudden Hearing Loss is defined as a hearing decline in 72 hours or less, resulting in a 30dB hearing reduction, and over at least 3 separate frequencies. The majority of the time, the hearing loss does not occur all at once, but over a period of a few hours.

Endocrine disorders, noise, infection, Head injuries, surgery, barotruma or medications can result in sudden sensori neural hearing loss

Treatment for sudden hearing loss: Treatment with steroids is the most common therapy for SSHL, with an unknown cause. Steroids usually work to reduce inflammation, decrease swelling, and help the body fight illness. Steroid treatment helps SSHL patients who also have conditions that affect the immune system.
A diet low in salt aids people with SSHL who also have Ménière's disease, a hearing and balance disorder. Immunosuppressant therapy should be considered if hearing loss relapses after steroids are stopped.

Weak Tympanic Membrane or Sinus Tympani Retracted Ear Drum


The outward or inward movement of tympanic membrane will depend on the type of pressure on it. The area behind the ear drum, the middle ear space, is filled with fluid in an ear infection. This is positive pressure pushes the eardrum outward. This is a common occurrence in children, especially during a cold. Sometimes the ear drum is retracted because of the scarring from repeated past infections. Blockage or deformities in the eustachian tube that connects middle ear to the nose makes a negative pressure behind the eardrum and the eardrum is sucked backwards. Weakness of the tympanic membrane after the ear drum heals following perforation or tympanostomy tubes, predispose to retraction in these areas. The proliferation and migration of new cells can also result in the expansion of ear drum deeper in to the ear. Treatment options include increasing middle ear pressure with Valsalva maneuver, ventilation tubes, nasal treatments, eustachian tube surgery, retraction pocket surgery and tympanoplasty.
