Investigation of the Serum Level of Vitamin D in Patients with Ear Cholesteatoma

Introduction: this study aimed to investigate the serum level of vitamin d in patients with ear cholesteatoma. materials and methods: this cross-sectional study was performed on 62 patients with middle ear cholesteatoma (case group) and 62 patients with simple chronic otitis media (control group). both groups had the same age (32±1 in the case group and 34±1 in the control group; p=0.973) and gender. vitamin d serum level was measured in the two groups. data analysis was conducted using t-test and anova. results: according to the statistical analysis, a significant relationship was observed between the serum level of vitamin d and middle ear cholesteatoma (p=0.000). the results showed that the serum level of vitamin d was lower in the case group, compared to the control group. conclusions: vitamin d serum level was lower in the cholesteatoma group. moreover, it was strongly associated with hearing loss, tinnitus, and vertigo.
