Résumé
The incidence of single-sided deafness（SSD） is increasing year by year. Due to the hearing defects of one ear, the ability of sound localization, speech recognition in noise, and quality of life of patients with single-sided deafness will be affected to varying degrees. This article reviews the intervention effects of different types of bone conduction hearing aids in patients with single-sided deafness and asymmetric hearing loss, and the differences of intervention effects between bone conduction hearing aids, contralateral routing of signal（CROS） aids, and cochlea implant（CI）, to provide a reference for the auditory intervention and clinical treatment of single-sided deafness and asymmetric hearing loss.

Various bone conduction hearing aids have been widely used to improve hearing fuction for the last 30 years. Sophono(R), a newly introduced device without percutaneous abutment, improved disadvantages of previously used bone conduction hearing aids. Recently, we experienced a case of Sophono(R) implantation in a patient presenting with mixed hearing loss followed by tumor surgery. The patient gained air conduction threshold of 60 dB HL compared to preoperative pure tone audiogram and a speech discrimination test in noisy environment showed improved results. Furthermore, the patient has had no cutaneous complications since implantation. The results of this case demonstrate the feasibility of implanting Sophono(R) in patients similar to this case. Considering its advantages of MRI compatibility and non-invasive surgery, as well as esthetical benefit, Sophono(R) implantation could be a preferable option for hearing rehabilitation.
