혈액 투석 중 양측 돌발성 난청이 순차적으로 발생한 만성신부전 환자 1예

Hemodialysis (HD) is a valid treatment modality in patients with chronic renal failure (CRF). Both CRF and HD have been noted as a possible cause of tinnitus, vertigo and sensorineural hearing loss (SNHL). There have been many efforts to elucidate the etiologic factors of hearing impairment in patients with CRF who underwent HD. But, it is difficult to explain association between them. Especially, sudden SNHL (SSNHL) in patients with CRF who underwent HD is highly unusual. We report, with a review of literatures bilateral SSNHL associated with CRF and HD as its treatment. At first, patient developed profound SSNHL in right side with benign paroxysmal positional vertigo (BPPV) after HD for 18 months. In spite of the treatment with systemic steroid and intratympanic dexamethasone injection (ITDI) hearing result was poor. And then SSNHL occurred in left side after 6 months. Hearing result was poor.
