Hyperbaric oxygen therapy for sudden hearing loss in enlarged vestibular aqueduct syndrome: A case report and review of literature

A 12-year-old girl with known bilateral enlarged vestibular aqueducts presented with vertigo and sudden profound hearing loss in her only hearing ear after COVID-19 infection. The hearing remained unchanged after systemic steroids, prompting treatment with salvage intratympanic dexamethasone and hyperbaric oxygen therapy with improvement in her hearing. This case report highlights the success of hyperbaric oxygen therapy in treating sudden sensorineural hearing loss and aims to raise awareness on its role in treating sudden hearing loss in patients with enlarged vestibular aqueduct.
