Cholesteatoma
A cholesteatoma is an abnormal growth of skin cells that develops in the middle ear behind the eardrum. Although it is not cancerous, it can behave like a destructive cyst by gradually enlarging and damaging nearby structures in the ear, including the bones responsible for hearing.
What Causes Cholesteatoma?
A cholesteatoma often develops as a result of repeated middle ear infections or long-term Eustachian tube dysfunction, which can lead to poor ventilation of the middle ear. This may cause part of the eardrum to collapse inward and trap skin cells, which then accumulate over time. In other cases, it may be present from birth, although this is less common.
cholesteatoma symptoms
In its early stages, a cholesteatoma may cause mild or no symptoms. As it grows, it can lead to persistent or recurring ear drainage that may have an unpleasant odor. Other common symptoms include hearing loss, a feeling of pressure or fullness in the ear, ear pain, dizziness, or balance problems. If left untreated, it can cause more serious complications due to ongoing damage to the middle ear structures.
The primary treatment for cholesteatoma is surgery. The goal of surgery is to remove the abnormal skin growth and prevent further damage to the ear. In some cases, a second procedure may be needed to ensure all of the cholesteatoma has been removed or to restore hearing. Antibiotics or ear cleaning may be used to control infection, but they do not eliminate the growth itself.
With appropriate treatment, most patients do well, although long-term follow-up is often needed to monitor for recurrence. Early diagnosis and management provide the best chance of preserving hearing and preventing complications.
