Ear canal malformations are structural abnormalities in the ear canal, which can affect hearing and ear health. These malformations can occur during fetal development and may involve the outer ear, middle ear, or both. Common types include atresia, where the ear canal is absent or closed, and stenosis, which is a narrowing of the canal. Individuals with ear canal malformations may experience symptoms such as hearing loss, frequent ear infections, or discomfort. Diagnosis typically involves physical examinations and imaging tests. Treatment options vary and may include surgery to reconstruct the ear canal or the use of hearing aids to improve auditory function.
