Case report and literature review of subclavian steal syndrome presenting with otologic symptoms as the initial clinical manifestation

This case demonstrates that SSS can present initially with sudden hearing loss and vertigo, underscoring the importance of otolaryngologists maintaining a high index of suspicion for vascular causes in atypical SSNHL. Early vascular imaging and prompt restoration of blood flow are critical to avoid permanent cochlear injury. This report enhances clinical recognition of rare vascular origins of inner ear ischemia and underscores the pathophysiological dissociation between vestibular recovery and auditory outcomes.
