Abstract
Otosclerosis, also known as otospongiosis, is a primary osteodystrophy of the otic capsule of the inner ear and one of the leading causes of deafness in adults. The rationale for medical therapy for otospongiosis is to slow down and eventually stop the phase of bone resorption. Conservative treatments include sodium fluoride (NaF), bisphosphonates, and other modern medicines. A systematic review of the existing and published articles and books until April 2021 has been conducted in Medscape, Google Scholar, PubMed, and other databases using appropriate terms. According to the results of the research, the administration of NaF for a period of at least six months stabilizes hearing thresholds (HTs), improves vestibular symptoms, and delays the worsening of tinnitus. The administration of bisphosphonates for a period of at least six months showed significant percentage differences in the improvement of hearing loss, dizziness, and tinnitus remission. In the already existing double-blind studies that were evaluated, groups of patients treated with bisphosphonates for at least 24 months showed greater stabilization of the mean air and bone conduction thresholds than groups of patients treated with a placebo. The new modern medications have not yet been widely administered clinically to draw useful conclusions, although the test results of some of their use are quite encouraging.
