Perda Auditiva Neurossensorial, Condutiva e Mista - Confira Diferenças

Summary

In this video, Clara Viana, a speech therapist specializing in hearing, tinnitus, and dizziness, explains the three main types of hearing loss: conductive, mixed, and sensorineural. She describes how hearing loss can occur in the outer, middle, or inner ear, and the differences in treatment approaches for each type. Conductive hearing loss can often be reversed with treatment, while sensorineural hearing loss is typically irreversible. The mixed type combines both issues. Clara emphasizes the importance of proper diagnosis and collaboration between otolaryngologists and speech therapists to provide the best treatment options for patients.

Takeaways

• 😀 The video introduces Clara Viana, a speech therapist specializing in hearing, tinnitus, and dizziness.
• 😀 The topic of the video focuses on hearing loss and its three main types: conductive, sensorineural, and mixed.
• 😀 Conductive hearing loss occurs when the sound conduction pathway is blocked, affecting the outer and middle ear but not the inner ear.
• 😀 Sensorineural hearing loss is caused by damage to the inner ear or auditory nerve, leading to irreversible damage to the hair cells in the cochlea.
• 😀 Mixed hearing loss is a combination of conductive and sensorineural hearing loss, affecting both sound conduction and the inner ear.
• 😀 Conductive hearing loss can often be treated or corrected, such as with earwax removal or treatment for ear infections.
• 😀 Sensorineural hearing loss is typically irreversible due to damage to the hair cells in the cochlea, and cannot be fixed through medical or surgical means.
• 😀 Most hearing loss cases are sensorineural, affecting a large portion of the population.
• 😀 Proper diagnosis is crucial to determine the cause and treatment plan for hearing loss, which could involve hearing aids, surgery, or medication.
• 😀 It is important for individuals to consult both an ENT doctor and a speech therapist for a comprehensive evaluation and appropriate intervention.

Q & A

What are the three types of hearing loss mentioned in the video?

The three types of hearing loss mentioned are conductive hearing loss, mixed hearing loss, and sensorineural hearing loss.

What causes conductive hearing loss?

Conductive hearing loss occurs when there is a problem in the external or middle ear that affects sound conduction, but the inner ear (cochlea) remains intact.

What is the role of the outer ear (pavilion) in hearing?

The outer ear (pavilion) helps funnel sound into the ear canal, assisting in sound transmission to the middle and inner ear for further processing.

What are the tiny bones in the middle ear, and what is their function?

The tiny bones in the middle ear are the malleus (hammer), incus (anvil), and stapes (stirrup). These bones help transmit sound vibrations from the eardrum to the inner ear.

How is sensorineural hearing loss different from conductive hearing loss?

Sensorineural hearing loss is caused by damage to the inner ear or the auditory nerve, typically involving permanent damage to the hair cells in the cochlea. In contrast, conductive hearing loss is due to problems in the outer or middle ear that impede sound conduction.

Can sensorineural hearing loss be reversed?

No, sensorineural hearing loss is usually irreversible because it involves damage to the hair cells in the cochlea, which cannot regenerate.

What is mixed hearing loss?

Mixed hearing loss is a combination of both conductive and sensorineural hearing loss, where there is an issue in the outer or middle ear along with damage to the inner ear.

What are some common causes of conductive hearing loss?

Common causes of conductive hearing loss include earwax buildup, otitis media (middle ear infections), and damage to the eardrum or ossicles.

Why is a proper diagnosis important for hearing loss?

A proper diagnosis is crucial to determine the exact cause of the hearing loss, which helps in choosing the correct treatment or intervention, such as surgery, medication, or hearing aids.

Who should evaluate and treat hearing loss?

A team involving an otolaryngologist (ENT specialist) and a speech-language pathologist (audiologist) should evaluate and treat hearing loss. The otolaryngologist handles medical treatments or surgeries, while the audiologist assists with hearing assessments and hearing aid fittings.
