The hearing loss of 21 patients with hypoparathyroidism was investigated by pure tone audiometry, short increment sensitivity index (SISI) test, Békésy audiometry, speech audiometry, and auditory brain stem response. Sensorineural hearing loss was found in 7 of 21 patients (13 of 42 ears) receiving no treatment for hypoparathyroidism or having chronic hypocalcemia. The high SISI score, presence of recruitment, and prolongation of the wave I (N1) latency suggested that the inner ear is responsible for hearing loss in these cases. Inner ear dysfunction was probably due to the low calcium level in inner ear fluid and/or the direct effect of vitamin D deficiency on the inner ear.
通过纯音听力测定、短增量敏感指数（SISI）测试、贝凯西听力测定、言语听力测定和听觉脑干反应，对21例甲状旁腺功能减退患者的听力损失情况进行了调查。在21例未接受甲状旁腺功能减退治疗或患有慢性低钙血症的患者中，有7例（42耳中的13耳）出现了感音神经性听力损失。高SISI评分、重振现象的存在以及I波（N1）潜伏期的延长表明，在这些病例中，内耳是听力损失的原因所在。内耳功能障碍可能是由于内耳液中钙水平较低和/或维生素D缺乏对内耳的直接影响所致。
