[Two cases of hearing loss following Hashimoto disease].
Hearing loss accompanies some of thyroid gland diseases especially those with hypothyroidism. Some authors state it correlates with autoimmune background of certain thyroid gland disturbances. We present two cases of patients with Hashimoto disease accompanied by fluctuating cochlear hearing loss and peripheral vestibular loss in one of the cases.


METHODS
there was unilateral worsening of bilateral hearing loss diagnosed previously after gentamycine treatment in 16 year old female with Hashimoto disease. There was significant improvement confirmed in audiological tests when the child became euthyroid. Second case presenting hearing loss and vertigo: 16 year old female with hypothyroidism and diabetes mellitus type 1 with high blood concentration of anticytoplasmic immunoglobulins lasting for 2 years. Bilateral cochlear perceptive hearing loss was diagnosed. In summary an association of autoimmune process as well as thyroid hormones blood level with inner ear condition was suggested. Trying to find the reason of observed disturbances one should consider wide differential diagnostics in all the cases of perceptive seemingly idiopathic cochlear hearing loss. The presented problem needs to be further investigated in larger clinical material.
