What does cholesteatoma operation have commonly?

If the external auditory canal is not completely blocked by the instrument, the cerumen hook can be used to slowly extend into the inner side of the cholesteatoma along the wall of the external auditory canal and hook it out. Because of the poor sensitivity of the posterior superior wall of the external auditory canal, cholesteatoma can be removed from the posterior superior wall first. This method is not suitable for cholesteatoma mass close to tympanic membrane or children who can not cooperate, so as to avoid damage to the external auditory canal and other important structures of middle ear.

If the cholesteatoma is hard and difficult to be removed by instruments, ear drops of 3% - 5% sodium bicarbonate solution or boric acid glycerin can be used first, 3-4 times a day. After 3 days, the softened cholesteatoma can be rinsed once or several times with a rinser. When washing, attention should be paid to the patients with acute or chronic suppurative otitis media and tympanic membrane perforation; The irrigating fluid should be close to the body temperature. If it is too cold or too hot, it may cause labyrinthine irritation and cause dizziness; The direction of flushing must be inclined to the posterior wall of the external auditory canal. If it is straight to the tympanic membrane, it may cause damage to the tympanic membrane. If it is straight to the foreign body, it may be flushed to the deep part of the external auditory canal and more difficult to remove. Patients with infection should be given anti-inflammatory treatment first. 3% boric acid glycerin or 4% phenol glycerin can be dripped several times a day. If necessary, antibiotics should be taken orally or intravenously. After the inflammation is controlled for 3-4 days, the drug can be removed. But it is difficult to control the inflammation completely. According to the experience, it is best to control the infection and remove the cholesteatoma gradually.

Under general anesthesia, endoscopic or microsurgical removal can be considered for patients with severe infection and difficult removal.
