Association between osteoporosis and otosclerosis in women

Similarities between osteoporosis and otosclerosis have been noted, including a similar association with the COL1A1 gene. Herein, the authors explore the possible clinical relationship between these two common disorders of bone. In this retrospective study, the medical charts of 100 women aged 50 through 75 years who had under,gone stapedectomy for otosclerosis were reviewed and the prevalence of osteoporosis in these women was noted. Similarly, the prevalence of osteoporosis was determined in a control group of 100 women aged 50 to 75 years with presbycusis. Fifteen of 100 women with otosclerosis had a concomitant diagnosis of osteoporosis as compared with four of 100 women with presbycusis, yielding a significant clinical association (p = 0.007) between otosclerosis and osteoporosis. This study suggests an association between otosclerosis and osteoporosis, providing impetus and justification for future prospective clinical studies and related research.
