简要总结
Safety and efficacy of intracochlear injection of glucocorticoid through the round window membrane in patients with profound or complete sudden sensorineural hearing loss
详细描述
- Whether is it safe when profound or complete sudden sensorineural hearing loss patients receive intracochlear injection of glucocorticoid through the round window membrane.
- Whether is it effective in reversing hearing capability when profound or complete sudden sensorineural hearing loss patients receive intracochlear injection of glucocorticoid through the round window membrane.
- Whether is intracochlear glucocorticoid injection more effective than intratympanic glucocorticoid injection for treating profound or complete sudden sensorineural hearing loss.
- Which glucocorticoid intracochlear injection is more effective in patients with profound or complete sudden sensorineural hearing loss.

入选标准
- •Age between 12 and 75 years Unilateral idiopathic sudden sensorineural hearing loss diagnosed by Pure tone test, CT and MRI Symptoms of sudden deafness occur within ≥ 7 days and, after conventional treatment, the average thresholds at 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz are ≥ 80 dBHL
排除标准
- •Bilateral sudden sensorineural hearing loss Hearing loss with known causes (e.g., Meniere's disease, retrocochlear pathology, history of otologic surgery, perilymphatic fistula, barotrauma) History in the past 6 months of ototoxic treatment such as chemotherapy, use of loop diuretics, high dose aspirin, etc.
- •History of sudden sensorineural hearing loss within the past 2 years History of ischemic diseases (cerebral infarction, myocardial infarction, peripheral arterial obstructive disease) Neuropsychiatric disorders (epilepsy, Parkinson's disease, Alzheimer's disease, multiple sclerosis) Severe hepatic or renal insufficiency The CT diagnosis is "abnormality of the round window niche".
