Sensorineural Hearing Loss:

  • Definition:

    • Sensorineural hearing loss is a type of hearing impairment that occurs due to damage to the delicate hair cells within the inner ear or damage to the auditory nerve pathways, both of which play a crucial role in transmitting sound signals to the brain.

  • Causes:

    • The causes of sensorineural hearing loss can be diverse and include:

    • Genetic factors
    • Aging (presbycusis)
    • Prolonged exposure to loud noises
    • Infections (such as meningitis or labyrinthitis)
    • Trauma to the head or ears
    • Tumors
    • Autoimmune diseases
    • Ototoxic medications
  • Symptoms:

    • Individuals with sensorineural hearing loss may experience the following symptoms:

    • Difficulty understanding speech, especially in noisy environments
    • Muffled or distorted sounds
    • Tinnitus (ringing, buzzing, or roaring noises in the ears)
    • Sensitivity to loud sounds
  • Treatment:

    • While sensorineural hearing loss is typically permanent, there are various treatment options available to manage the condition:

    • Hearing aids: These devices amplify sounds, making them easier to hear.
    • Cochlear implants: Surgically implanted devices that directly stimulate the auditory nerve to provide sound perception.
    • Assistive listening devices: These devices help in specific listening situations, like watching TV or talking on the phone.
    • Aural rehabilitation: Programs that help individuals with hearing loss improve their communication skills and adjust to their hearing impairment.
