Hearing Loss and Oxidative Stress: A Comprehensive Review

Area of Science:

• Otorhinolaryngology
• Neuroscience
• Biochemistry

Background:

• Hearing loss affects millions globally and is increasingly linked to oxidative stress.
• Reactive oxygen species (ROS) play a critical role in cochlear damage and auditory system dysfunction.
• The cochlea's high metabolic rate and limited blood supply render it vulnerable to oxidative injury.

Purpose of the Study:

• To comprehensively review the relationship between oxidative stress and hearing loss.
• To explore the mechanisms of oxidative damage in the auditory system.
• To evaluate the efficacy of antioxidant interventions for hearing loss.

Main Methods:

• Systematic review of existing literature on oxidative stress and hearing loss.
• Analysis of studies investigating ROS in cochlear damage.
• Evaluation of data on antioxidant therapies and other interventions.

Main Results:

• Oxidative stress is implicated in age-related, noise-induced, and ototoxic hearing loss.
• Antioxidant treatments demonstrate potential in preclinical and clinical studies for mitigating hearing loss.
• Novel approaches like targeted drug delivery and gene therapy are emerging.

Conclusions:

• Oxidative stress is a key factor in multiple types of hearing loss.
• Antioxidant interventions offer a promising therapeutic avenue.
• Further research into personalized treatments is crucial for effective hearing loss management.
