Official title

Safety and Efficacy of Intracochlear Injection of Glucocorticoid Through the Round Window Membrane in Patients With Total Sudden Sensorineural Hearing Loss

Overview

This study is a prospective, randomized pilot study. To verify safety and efficacy of intracochlear injection of glucocorticoid through the round window membrane in patients with total sudden sensorineural hearing loss safety and efficacy in total sudden sensorineural hearing loss patients as an early salvage therapy.

Detailed description

The main questions it aims to answer are:

1. Whether is it safe when total sudden sensorineural hearing loss patients receive intracochlear injection of glucocorticoid through the round window membrane. 2. Whether is it effective in reversing hearing capability when total sudden sensorineural hearing loss patients receive intracochlear injection of glucocorticoid through the round window membrane. 3. Whether is intracochlear glucocorticoid injection more effective than intratympanic glucocorticoid injection for treating total sudden sensorineural hearing loss. 4. Which glucocorticoid intracochlear injection is more effective in patients with total sudden sensorineural hearing loss.

Interventions

  • Drug intracochlear triamcinolone acetonide injection
    intracochlear triamcinolone acetonide injection of through the round window membrane
  • Drug intracochlear injection of dexamethasone through the round window membrane
    intracochlear injection of dexamethasone sodium phosphate through the round window membrane
  • Drug intracochlear dexamethasone injection and intratympanic dexamethasone injection
    intracochlear dexamethasone sodium phosphate injection of through the round window membrane, intratympanic dexamethasone sodium phosphate injection through the tympanic membrane
  • Drug intratympanic dexamethasone injection
    intratympanic dexamethasone sodium phosphate injection (10mg/ml) through tympanic membrane,once every other day, for a total of 4 injections.

Primary outcome measures

  • Change from Baseline in pure tone audiometry (PTA) [Time frame: Baseline, Week 2, Week 4, Week12, Week24]
  • Change from Baseline in auditory brainstem response (ABR) [Time frame: Baseline, Week 2, Week 4, Week12, Week24]
  • Change from Baseline in auditory steady state response (ASSR) [Time frame: Baseline, Week 2, Week 4, Week12, Week24]
  • Change from Baseline in speech Discrimination Scores [Time frame: Baseline, Week 2, Week 4, Week12, Week24]
Secondary outcome measures (3)
  • change from baseline in tinnitus handicap inventory [Time frame: Baseline, Week2, Week4, Week12, Week24]
  • change from baseline in dizziness handicap inventory [Time frame: Baseline, Week2, Week4, Week12, Week24]
  • change from baseline in quality of life score [Time frame: Baseline, Week2, Week4, Week12, Week24]

Eligibility criteria

Inclusion criteria

Age between 18 and 65 years Unilateral idiopathic sudden sensorineural hearing loss greater than 95dB at the average of 4 frequencies (500 Hz, 1000 Hz, 2000 Hz and 4000 Hz) in PTA (contralateral hearing is less than 30dB) at the onset of sudden hearing loss Participant who were treated with standard treatment for 14 days, but no recovery was confirmed as type IV (final hearing level with hearing gain of ≤15 dB) at the end of the 14-day treatment

Exclusion criteria

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"

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
