How harmful is cholesteatoma of the external auditory canal?

It may extend periphery, causing intracranial and extracranial complications. It's solved by surgery.

Deafness, facial paralysis, brain injury, as soon as possible**, of course this is a severe case of the face. Generally speaking, earplugs have a headache and can't stand it, I was like this some time ago, I just did it today, and I found Dr. Li Peng of the Department of Otology in the Third Affiliated Hospital of Sun Yat-sen University in Guangzhou, I found several, there are always good people in the world, and I will always meet, Dr. Li is the most professional, friendly and kind one of the four ear doctors I have met, I am very grateful to him. Because the onset is a chronic process, it doesn't feel much at first.

Later on, there will be signs of earache and ear gambling, and it is likely to be misdiagnosed as cerumen embolism at first. Remove the cholesteatoma with an ear fiber endoscope, quickly. There will be pain.

In severe cases, surgery may be required.

The main hazards are extensive destruction of the outer auditory canal, middle ear mastoid process and adjacent bones, causing hearing loss, and even serious intracranial and extracranial complications that are life-threatening. It should be removed promptly.

At present, the most advanced methods of cholesteatoma of the external auditory canal are mainly to remove cholesteatoma, anti-infection, scraping granulation, external auditory canal plasty, and modification of mastoid process**.

If your cholesteatoma is not infected, then cerumen removal is recommended, and if there is an infection, the infection must be controlled first, and the inflammation of the cholesteatoma will be removed only if it is completely removed.

Everyone may behave differently and need to be checked and ** in time.

The so-called cholesteatoma is actually formed due to the accumulation and necrosis of exfoliated epithelial cells, which are like a snowball. The destructive effect of cholesteatoma is to compress and erode the surrounding tissues, resulting in osteonecrosis.

Cholesteatomas are divided into two main categories, one is congenital cholesteatoma, also called primary cholesteatoma. This is due to the presence of epithelial cells in the middle ear mastoid cavity during embryonic development. Due to the metabolism of epithelial cells, they continue to fall off, accumulate and increase in size, forming pressure on the surrounding tissues, causing damage to the mastoid bone, and even invading the brain tissue, causing intracranial complications.

This type of cholesteatoma may not have a history of chronic suppurative otitis media, but may be found in the presence of complications or during other tests. The other type of cholesteatoma is acquired, also called secondary cholesteatoma, the most common is chronic purulent otitis media (cholesteatoma type) secondary to chronic purulent otitis media, which is due to otitis media caused by perforation of the edge or flaccid part of the eardrum, and the epithelial cells of the external auditory canal grow into the middle ear mastoid cavity, and then the epithelium falls off and accumulates; There is also an acquired cholesteatoma otitis media, which is secondary to catarrhal otitis media, which is gradually formed due to the inversion of the loose part of the tympanic membrane caused by the negative pressure of the middle ear. This type of lesion is mostly confined to the upper tympanic cavity and is suitable for extratympanic surgery to enhance hearing.

Diagnosis is confirmed by history and signs, such as a characteristic white cholesteatoma-like mass incarceration in the ear canal, hyperemia, swelling, stenosis, and granulation of the ear canal** on examination of the ear canal. In order to further clarify the staging and guide the progression, high-resolution thin-slice CT examination of the temporal bone should be performed to understand the lesions of the external auditory canal and the extent of bone destruction, the destruction of adjacent tissues, and the relationship between the lesion and the surrounding tissue structure, especially the relationship between the mastoid segment of the facial nerve and cholesteatoma of the external auditory canal. After surgery, cholesteatoma-like tissue is sent for pathological examination to confirm the diagnosis.
