[Hearing and balance in metabolic bone diseases].

There are reports that hearing loss is one of the clinical manifestations of metabolic bone diseases. Demineralization can lead to a reduction in ossicular mass. Paget's disease can reveal loss of mineral density of the cochlear bone. Ear bone remodeling in osteoporosis is similar to the changes in otosclerosis. Moreover, osteoporosis, osteogenesis imperfecta and otosclerosis have a similar genetic mechanism. According to some researchers osteopenia and osteoporosis may well be associated with idiopathic benign positional vertigo (BPV). Dysfunction of the organ of hearing and balance in patients with renal insufficiency may be due to disturbances in calcium phosphate balance and renal osteodystrophy in the course of the disease. Proving the presence of hearing loss in patients with metabolic bone diseases may lead to determining the new indications for bone densitometry in some patients with hearing impairment. Furthermore, audiological examination in patients with osteoporosis may be important because of the impact of hearing loss on prognosis for patients with metabolic bone diseases.
