What is the symptom of ear cholesteatoma?

summary

The so-called ear cholesteatoma is not a true tumor, but a cystic structure in the middle ear cavity. For the tympanic membrane, external auditory canal stratified squamous epithelium in the middle ear cavity growth, accumulation into a mass, containing cholesterol crystals, so called cholesteatoma. What are the symptoms of ear cholesteatoma? Let's go.

What is the symptom of ear cholesteatoma?

First, chronic simple otitis media belongs to the "safe" type of otitis media, which can be treated conservatively. Perforation of the tympanic membrane is mostly central. The perforation is located in the tension part of the tympanic membrane. There is residual tympanic membrane around it. It is often caused by upper respiratory tract infection invading the middle ear through the eustachian tube. The pathological changes are limited to the mucous membrane and periosteum of the middle ear. Patients may have recurrent otorrhea and hearing loss, CT examination showed no bone destruction and cholesteatoma formation, mastoid for gasification or barrier type.

Second: cholesteatoma type and bone ulcer type (granulation type) otitis media belong to the risk type of otitis media, conservative drug treatment is almost ineffective, neonatal hearing screening, once found only surgical treatment. Tympanic membrane perforation in the relaxation or edge, lesions involving tympanic ossicular chain, serious damage, often pus odor, hearing loss is obvious, prone to serious intracranial, external and temporal bone complications, hearing aid technology application, charity, great harm.

Third: hearing loss may be the only chief complaint of cholesteatoma without infection. In the early stage, most of them were conductive deafness with varying degrees. The upper tympanic cavity cholesteatoma, hearing can be basically normal. Even if the part of the ossicle is damaged, because cholesteatoma can be used as a sound bridge between the ossicles, the hearing loss may not be very serious. When the lesion involved the cochlea, the deafness was mixed. Severe cases may be total deafness.

matters needing attention

The operation should be performed as soon as possible, the focus should be removed thoroughly, the intracranial and extracranial complications should be prevented, and the hearing should be reconstructed.
