Hearing loss affects millions of people worldwide, and as doctors, we continually search for better ways to help our patients. Recent research from India highlights the potential of gene therapy in treating sensorineural hearing loss (SNHL), a common type of hearing loss caused by genetic mutations and damage to the inner ear.

What Is Gene Therapy for Hearing Loss?

Gene therapy involves replacing, editing, or suppressing defective genes to restore normal function. Unlike current treatments—such as cochlear implants, which can be expensive and sometimes fail to mimic natural hearing—gene therapy targets the root cause of genetic hearing loss. Addressing faulty genes directly could lead to a long-term solution for both genetic and some non-genetic forms of hearing impairment.

Key Research and Advances

Dr. Santosh Kumar Swain, from the Department of Otorhinolaryngology and Head and Neck Surgery at the All India Institute of Medical Sciences in Sijua, Patrapada, Bhubaneswar, Odisha, India, recently shared insights in a review published in Apollo Medicine. In an interview with Medical Dialogues, Dr. Swain explained how gene therapy is emerging as a less invasive alternative to traditional treatments.

The review highlights:

• The Use of Next-Generation Sequencing: Advanced screening approaches help diagnose hearing loss by identifying genetic mutations.
• Vectors for Gene Delivery: Researchers are exploring viral and non-viral vectors to deliver therapeutic genes to the target cells in the inner ear.
• Challenges in Clinical Practice: There is a critical therapeutic time window for interventions, and challenges remain in improving the specificity of gene delivery and understanding immune responses.
• Future Directions: Beyond hair cells, future treatments may also target peripheral ribbon synapses, spiral ganglion neurons, and auditory neurons, which play a role in complex sound processing.

Why Is This Important for Clinical Practice?

Traditional solutions like hearing aids and cochlear implants often fall short in restoring natural sound quality, particularly in noisy environments or when appreciating music. Gene therapy holds the promise of overcoming these limitations by offering a more natural and durable solution. With further clinical trials and technological improvements, this treatment could revolutionize how we manage genetic hearing loss and other forms of sensorineural hearing loss.
