Diagnostic Criteria for Sudden Deafness
The National Academic Conference on Diagnostic Criteria and Evaluation Criteria for the Treatment of Meniere’s Disease and Sudden Deafness, organized by the Chinese Medical Association Society of Otolaryngology and the Editorial Board of the Chinese Journal of Otolaryngology, was held in Shanghai from October 22 to 24, 1996, and this standard was the standard developed in this conference.
Definition: Sudden onset of sensorineural hearing loss of unknown origin.
Diagnosis basis
1.Sudden onset of non-volatile sensorineural hearing loss, often moderate or severe.
2.The cause is unknown.
3.It may be accompanied by tinnitus.
4.It may be accompanied by vertigo, nausea and vomiting, but not recurrent.
5.No other symptoms of cranial nerve damage except for the VIII cranial nerve.
Treatment principles
Early comprehensive treatment, actively search for the cause of the disease.
1.General treatment: pay attention to rest, appropriate sedation, and actively treat related diseases, such as hypertension and diabetes.
2.Improve inner ear microcirculation drugs.
3.Glucocorticoid drugs.
4.Reducing blood viscosity and anticoagulant drugs.
5.Neurotrophic drugs.
6.Other treatment, such as mixed oxygen, hyperbaric oxygen, etc.
Treatment effect grading
1.Cured: The damaged frequency hearing threshold is restored to normal, or reaches the level of healthy ear, or reaches the level before the disease.
2.Significant effect: the average hearing of the damaged frequency is improved by more than 30 dB.
3.Effective: the average hearing of the damaged frequency is improved by 15-30 dB.
4.Ineffective: the average hearing improvement of less than 15 dB in the damaged frequency.
