Hearing impairment in idiopathic hypoparathyroidism and pseudohypoparathyroidism

Sensorineural hearing impairment is a lesser known feature of hypoparathyroidism. The hearing of 20 patients with idiopathic hypoparathyroidism was investigated by pure-tone audiometry. Bilateral sensorineural hearing loss was found in three (15%). Sensorineural hearing loss is considered to be associated with a prolonged low calcium level in the inner ear fluid and is a possible complication of hypoparathyroidism.
