•Adults aged 19 and older, up to 75 years of age, with asymmetric sensorineural hearing loss.
•-Those whose worse ear has a pure-tone average (PTA) hearing threshold of PTA = 70dB at 500, 1000, 2000, and 4000 Hz, with an aided Speech Discrimination Score (SDS) of = 50% (at 60dB), and whose better ear has a hearing threshold of 40dB = PTA <70dB, with an aided SDS of = 80% (at 60dB).
•-Individuals with post-lingual deafness (hearing loss acquired after language acquisition).
•-Those for whom significant improvement in the hearing of the deaf ear through conventional hearing aids is not expected.
•-No contraindications for general or local anesthesia.
•-Patients who voluntarily agree to participate in the clinical study and provide written consent.

•-Individuals with acquired hearing loss (especially if it is caused by sudden deafness, for which there is still a possibility of spontaneous recovery).

•-Any other cases deemed inappropriate for this trial by the clinical trial personnel's judgment.
