summary

Cholesteatoma otitis media was changed to cholesteatoma in the guideline of clinical classification and surgical classification of otitis media issued by Chinese Medical Association in 2012. Previously, cholesteatoma otitis media was considered to be the most serious type of chronic suppurative otitis media, but in fact, it is the growth of squamous epithelial tissue in the middle ear and mastoid. Its formation mechanism, pathology and prognosis are different from those of chronic suppurative otitis media. The so-called cholesteatoma is the accumulation of exfoliated epithelium. The more it gathers, the bigger it becomes. It expands all around continuously, causing the destruction of adjacent bone and possibly causing complications of surrounding organs. Therefore, the treatment of this disease is a diagnosis should be recommended surgery, and the main purpose of surgery is not to raise high hearing and no pus, but to prevent complications.

When the lesion involved the cochlea, the deafness was mixed. Severe cases may be total deafness.

The relaxation part of tympanic membrane was invaginated and perforated, and the tension part was invaginated and thickened; Or perforation of the upper edge of the posterior tympanic membrane, gray white cholesteatoma scab or red granulation tissue polyp tissue can be seen in the tympanum, often accompanied by purulent secretions.
