Cholesteatoma Surgery (Infection of Inner Ear)


Ear infection problems are most common conditions suffered by individuals. Cholesteatoma is a destructive and expanding growth in the middle ear and/or mastoid process, characterized by keratinizing squamous epithelium. The enzymes released by the cholesteatoma actively erode bone once activated by moisture; eventually cause infection of inner ear. The outcome of this erosion is the nerve loss, deafness, severe imbalance and dizziness. The cholesteatoma also erode the thin plate of bone that separates the roof of the ear from the brain. In extreme cases, the exposure of the covering of the brain can lead to brain infection and other severe complications. Cholesteatoma are not cancerous but are benign tumors. The improper function of the Eustachian tube may contribute to the formation of a cholesteatoma. If the Eustachian tube does not fails to equalize the pressures in the middle ear due to allergy, a cold, or sinusitis, negative pressure may build up behind the ear drum. This retraction of the drum leads to the formation of a pocket. Deepened pocket gets trapped in the ear as a skin cyst or sac. The fallen dead skin cells expand the sac and a cholesteatoma develops.

Cholesteatoma may be congenital or acquired. Baby ear infections are mostly congenital cholesteatoma; epidermal cysts are formed due to developmental abnormality. Acquired cholesteatoma are more common form of adult ear infections, can be caused by a tear or retraction of the ear drum due to middle ear inflammation or implantation following trauma.

Signs of ear infection: Ear infections are common with cholesteatoma and can lead to granulation tissue and foul smelling discharge that may contain blood. Often the debris is infected with Pseudomonas aeruginosa or other bacteria or organisms. A cholesteatoma cyst consists of peeling layers of scaly or keratinized layers of epithelium, which may also contain cholesterol crystals.

Ear infection symptoms: The majority of patients with cholesteatoma have ear discharge or hearing loss or both in the affected ear. Other common symptoms of infection may include: balance disruption, tinnitus, ear ache, headaches and bleeding from the ear. There can also be facial nerve weakness and dizziness.

Treatments for ear infection: Cholesteatoma is a serious condition and requires prompt treatment. Medical treatments for ear infection concentrate on drying the infection within the ear. Antibiotics are given both by mouth and drops in the ear to treat infection. The cleaning of the ear Cholesteatoma under the surgical microscope, is one of the preliminary and important remedies for ear infection. Cholesteatoma surgery is performed to remove the sac of squamous. The majority of cholesteatoma require that an incision be made behind the ear to expose the affected area adequately. The primary purpose of surgery is to remove the cholesteatoma to eliminate the infection and create a dry ear.
