What are the detection methods of auditory neuropathy?

1. Tinnitus is the first symptom, and the hearing on one side gradually decreases to deafness.

2. Typical cerebellopontine angle syndrome: auditory nerve, facial nerve, trigeminal nerve and posterior cranial nerve disorder, cerebellar damage, brain stem compression and other symptoms and signs.

3. Chronic intracranial hypertension: headache, vomiting, papilla edema.

4. The X-ray photos of the skull show the enlargement of the internal auditory canal and the destruction of the rock ridge. Cranial CT showed equal density or low density source of cerebellopontine angle and obstructive hydrocephalus, and enhanced scan showed that the source of the disease was partially enhanced. Cranial magnetic resonance imaging showed that the T 1 weighted image of cerebellopontine angle showed low signal or equal signal, and the T2 weighted image showed high signal occupation, which enhanced the scanning of the disease.

5. Cerebral angiography is an invasive examination, its localization qualitative rate is not as good as that of computed tomography or magnetic resonance imaging, but it can understand the blood supply of tumor and intervene embolization to reduce intraoperative bleeding.

6. The diagnosis is clear, surgery is needed, and basic examination is given priority to.
