简要总结

This study is a prospective, randomized pilot study. To verify an efficacy/safety of the mixed drug injectable delivery vehicle for treating intractable hearing loss. Hearing test, endoscopy of tympanic membrane and CT scans will be conducted after intratympanic treatment for evaluation.

详细描述

The goal of this clinical trial (pilot study) is to evaluate the Efficacy and Safety of Combined Hyaluronic Acid and Dexamethasone Treatment in Patients with Hearing Loss. The main questions it aims to answer are: • Q1. Verification of safety, • Q2. Therapeutic effect of drug injection on sensorineural hearing loss. Participants will undergo several assessment tests (Verification of adverse effects in the external and middle ear through endoscopy, Confirmation of adverse effects through imaging, Hearing test to check for additional hearing loss, Check if subjective ear fullness persists for more than a week aside from the drug effect). If there is a comparison group: Researchers will compare dexamethasone and hyaluronic acid to verify hearing improvement and safety.

研究组 & 干预措施

Dexamethasone+Hyaluronic Acid+ICG

Experimental

The experimental group received a single injection of Dexamethasone (5mg/ml) and Hyaluronic acid (D+HA) mixed in a 1:1 ratio (with a possibility of a second injection if necessary). Additionally, two drops of Indocyanine Green (ICG: 25mg) were added, approximately 100μl (2.5mg/ml).

干预措施: Hyaluronic acid (Drug)

Dexamethasone+Saline+ICG

Active Comparator

The experimental group received a single injection of Dexamethasone (5mg/ml) and Saline (D+Saline) mixed in a 1:1 ratio (with a possibility of a second injection if necessary). Additionally, two drops of Indocyanine Green (ICG: 25mg) were added, approximately 100μl (2.5mg/ml).
