Conductive deafness malformed external ear

Conductive Deafness with Malformed External Ear is a medical condition that affects the hearing ability of an individual. This condition is characterized by an impairment in the sound transmission from the external ear to the inner ear, coupled with abnormalities in the structure of the external ear. Conductive deafness occurs when there is a problem conducting sound waves anywhere along the route through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles).

Causes

The causes of Conductive Deafness with Malformed External Ear can vary widely, ranging from congenital abnormalities, such as Microtia or Atresia, to acquired conditions like infections, trauma, or tumors. Congenital conditions are present at birth and may affect the development of the ear's structure, leading to both the malformation of the external ear and conductive hearing loss.

Symptoms

Individuals with this condition may exhibit symptoms such as:

• Reduced hearing acuity
• Difficulty understanding speech, especially in noisy environments
• A feeling of fullness or pressure in the ears
• Visible deformity or abnormality of the external ear

Diagnosis

Diagnosis of Conductive Deafness with Malformed External Ear involves a comprehensive audiological evaluation and physical examination. Tests may include:

• Otoscopy: Examination of the outer ear and eardrum
• Tympanometry: Assessment of the middle ear function
• Pure tone audiometry: Measurement of hearing sensitivity

Treatment

Treatment options vary based on the underlying cause and severity of the condition but may include:

• Surgical reconstruction of the external ear
• Hearing aids or other assistive listening devices
• In cases of infection, medical treatment with antibiotics
• Bone-anchored hearing aids (BAHAs) for those who cannot benefit from conventional hearing aids

Prognosis

The prognosis for individuals with Conductive Deafness with Malformed External Ear largely depends on the cause and the effectiveness of the treatment. Surgical and hearing aid technologies have significantly improved, offering better outcomes for many patients.
