(1) hearing loss: sudden onset; sometimes tinnitus occurs first, followed by hearing loss, which can occur within seconds, or gradually reach the peak within hours, a day or longer; hearing loss is mostly on one side, and the incidence on both sides is less than 7%.

① pure tone audiometry: the hearing curve shows different types of sensorineural deafness.

② acoustic impedance audiometry: the tympanogram is A-shaped, and the emission threshold of stapes muscle is related to hearing impairment, which may have rejuvenation performance.

(3) the auditory threshold of brainstem response was basically consistent with the subjective threshold.

⑤ vestibular function test: the vestibular function of the affected side can be normal or decreased, and the degree of its function loss is related to the severity of hearing loss and vertigo.

[principles of diagnosis and treatment]

< P style = "color:; font family: Arial, Verdana, sans serif;" >
(1) diagnosis: according to the history, clinical manifestations and examination results. It is important to differentiate from other diseases with the same symptoms, such as Meniere’s disease, pons angle tumor, etc.

(2) treatment principle: according to emergency treatment, improve inner ear microcirculation, enhance nerve nutrition, promote energy metabolism, and cooperate with vitamin and hormone treatment. According to the analysis of clinical data, although sudden deafness has a high self-healing rate, the earlier medication is given, the better the effect will be.

(3) factors affecting the curative effect: generally related to the age of onset, the course of disease, hearing loss and whether accompanied by vertigo or chronic disease.

(4) if the hearing loss of both ears is serious and the above treatment is ineffective, the hearing aid can be selected
