Magnesium therapy in acoustic trauma.
Level 5 - mechanism / opinion, no new human data
Narrative review of animal and human literature without systematic search methodology.
What was done
This narrative review synthesizes mechanisms of noise-induced hearing loss (NIHL) and summarizes findings from animal and human studies regarding magnesium supplementation for NIHL prevention and treatment.
What was found
The abstract provides no numerical data or effect sizes. It reports that acoustic trauma causes mechanical and metabolic injury (ionic imbalance, ischemia, excitotoxicity, and free radical production leading to apoptosis or necrosis) and notes that magnesium crosses the hematocochlear barrier to exert neuroprotective and vasodilatory actions that reduce cochlear damage.
Why it matters
Because magnesium is cheap, widely available, and has a well-characterized safety profile, it represents an accessible candidate for mitigating noise-induced hearing loss if supported by rigorous trials.
Limits
The abstract describes a narrative review without reporting search methods, included study designs, participant counts, or quantitative effect sizes. The described evidence is derived partly from animal models.
Cited by
- context Animal model measurements show that magnesium levels in the cochlea decrease or fluctuate more than any other ion following acoustic trauma.
