Profound sensorineural hearing loss (PSHL) is not uncommonly encountered in otology. In clinics, there is a high incidence of otolithic damage in patients with PSHL, but relevant reports are few. Sharing a continuous membranous structure and similar receptor cell ultrastructures, the cochlea and vestibule may be susceptible to the same harmful factors. Disorders of the inner ear may result in a variety of manifestations, including vertigo, spatial disorientation, blurred vision, impaired articulation, and hearing impairment. Considering the diversity of clinical symptoms associated with PSHL with otolithic dysfunction, it may be frequently misdiagnosed, and objective means of testing the function of otolithic organs should be recommended for hearing-impaired patients. Vestibular-evoked myogenic potentials (VEMPs) via air-conducted sound are of great importance for the diagnosis of otolithic function. Hearing devices such as cochlear implants are commonly accepted treatments for PSHL, and early identification and treatment of vestibular disorders may increase the success rate of cochlear implantation. Therefore, it is necessary to increase awareness of otolithic functional states in patients with PSHL.
重度感音神经性听力损失(PSHL)在耳科学中并不罕见。在临床上,PSHL患者中耳石损伤的发生率很高,但相关报道较少。耳蜗和前庭共享连续的膜性结构且受体细胞超微结构相似,可能易受相同有害因素影响。内耳疾病可能导致多种表现,包括眩晕、空间定向障碍、视力模糊、言语不清和听力障碍。考虑到PSHL伴耳石功能障碍相关临床症状的多样性,其可能经常被误诊,对于听力受损患者应推荐客观的耳石器官功能检测方法。经气导声音诱发的前庭肌源性电位(VEMPs)对耳石功能诊断具有重要意义。人工耳蜗等听力设备是PSHL常用的治疗方法,早期识别和治疗前庭疾病可能会提高人工耳蜗植入的成功率。因此,有必要提高对PSHL患者耳石功能状态的认识。
