Cholesteatoma is a condition in which a pocket of skin tissue forms in the inner ear, according to MedlinePlus. Specific symptoms of a cholesteatoma include dizziness, hearing loss in one ear, pain or numbness around the ear and drainage from the ear. Surgery is needed to remove the cyst. If not, complications of cholesteatoma can result.
Brain Abscess
A cholesteatoma can lead to a brain abscess. MedlinePlus explains that a brain abscess is a condition in which pus and immune cells actually accumulate in the brain. Some specific symptoms of a brain abscess include reduced sensation, aching of the shoulders, neck or back, confusion, drowsiness, irritability and a headache. A brain abscess also can lead to vomiting, weakness, a lack of coordination, a fever and chills.
MedlinePlus reports that risk factors for developing a brain abscess include a weak immune system, a chronic disease and certain medications such as corticosteroids that suppress the immune system. Treatment for a brain abscess involves taking antibiotic or antifungal medications. Sometimes, surgery may be necessary to relieve the pressure.
Labyrinthitis
Cholesteatoma also can lead to the development of labyrinthitis, an irritation and swelling of the inner part of the ear, MedlinePlus says. Symptoms of labyrinthitis include dizziness, vomiting, hearing loss, nausea, ringing in the ears and trouble focusing the eyes. Labyrinthitis can lead to a sensation that the room is spinning (vertigo).
Some risk factors for labyrinthitis include stress, smoking, fatigue, a respiratory infection, an ear infection and drinking alcohol. Taking such medications as antihistamines, compazine, corticosteroids and sedative-hypnotics can help manage symptoms of labyrinthitis.
Meningitis
A cholesteatoma can lead to meningitis, a condition in which the membranes around the brain and spinal cord become infected. Specific meningitis symptoms include a severe headache, a fever, a stiff neck, light sensitivity, seizures, a skin rash and vomiting. Meningitis can lead to confusion, leg pain and pale skin.
Bacteria, viruses and conditions such as a cholesteatoma can make people susceptible to developing meningitis. Its treatment involves taking antibiotic medications to eliminate the bacteria. Usually, viral meningitis can resolve on its own.
