Objective:

To evaluate the effect of vitamin D supplementation on hearing recovery in patients with sudden sensorineural hearing loss and vitamin D deficiency.

Approach:

Key Findings:

• Patients receiving vitamin D showed greater improvement in hearing at 2000 Hz and 4000 Hz compared to the placebo group.
• No significant advantage of vitamin D was observed at lower frequencies (500 and 1000 Hz) or at 6000 Hz.
• Both groups improved in hearing over 30 days, consistent with corticosteroid treatment expectations.

Interpretation:

The study suggests that vitamin D supplementation may enhance recovery of hearing at specific frequencies crucial for speech perception, although the overall contribution of vitamin D remains unclear.

Limitations:

• Small sample size.
• Single-center design.
• Short follow-up period.
• Inability to isolate the effects of corticosteroids, spontaneous recovery, and vitamin D.

Conclusion:

Further studies with larger sample sizes and extended follow-up are needed to confirm the potential benefits of vitamin D in auditory recovery.
