Audiological evaluation in patients with vitamin D deficiency

Abstract

Background: Vitamin D status has been linked to proper hearing and vestibular functions. Vitamin D deficiency was correlated with ear, nose, and throat patients. Also, several studies suggested the possible relationship between vitamin D deficiency and hearing loss primarily of sensorineural type.
Methods: The current study was performed on Seventy-five subjects, the cases were allocated into two groups; control group (of 25 healthy subjects with Serum level of 25(OH) D (>20 ng/mL)), and study group consisted of 50 adults which were divided equally into two subgroups, subgroup I; adults with serum level of 25-hydroxy vitamin D <12 ng/ml, and subgroup II; adults with serum level of 25-hydroxy vitamin D=12-20 ng/mL. All cases were subjected to basic audiological evaluation.
Results: There were no statistically remarkable variations between study and control groups in pure tone threshold at different frequencies, speech reception thresholds, and word discrimination scores.
Conclusions:  The present study demonstrated that hearing sensitivity was not affected by vitamin D status.
