External auditory canal atresia
Also known as: Atresia of the external acoustic meatus · Congenital aural atresia · Gehörgangsatresie · Atresie des äußeren Gehörgangs · Ear canal atresia · …
Overview
What it is
External auditory canal atresia (EACA) is a birth defect of the ear canal where the outer ear opening is partially or completely closed. This structural blockage prevents sound waves from reaching the eardrum and stops the natural drainage of earwax and fluids. Because the canal is sealed, it creates a trapped space prone to severe buildup and pressure.
How it presents
The condition is usually noticed in puppies, who may show signs of hearing impairment or deafness in the affected ear. As fluids build up, the dog may shake its head, scratch at its ear, or show signs of pain and sensitivity when touched around the head.
Treatment
This condition is treatable through a one-time surgical procedure to reconstruct the canal or remove it entirely. This complex surgery typically costs between €1,500 and €5,000.
How it's tested
