The Voice-Restoring Treatment: A New Hope for the Speech-Impaired
By Karl Mercer

"I've never been able to sing, I've never been able to shout - I've just been limited in so many ways."
These words, spoken by David Metherell, resonate deeply with those who have faced speech challenges. David, a 45-year-old critical care nurse, has struggled with speaking since his childhood due to a rare strain of the human papillomavirus (HPV) that damaged his vocal cords. This condition has left him with scarred vocal cords, a croaky voice, and difficulty speaking for extended periods.
During the COVID-19 pandemic, when he wore full-face masks and protective equipment, David's speech challenges became even more apparent. He struggled to project his voice, often feeling like it had suddenly stopped, as if someone had their hand over his mouth.
Referred to the Ear, Nose, and Throat (ENT) Clinic at Guy's Hospital, David became one of the first patients to receive a groundbreaking new treatment involving platelet-rich plasma (PRP). This innovative approach involves extracting plasma from his blood and injecting it into his vocal cords or folds, a technique previously used for tendon or ligament injuries.
The treatment has shown remarkable results. Consultant Shiying Hey and her team have treated 10 patients, all of whom reported significant improvements in their voices. The PRP treatment is not only effective but also cost-effective, as it utilizes the patient's own blood, and it can lead to longer-lasting results by encouraging vocal cord regeneration and accelerating the healing process.
David, after three injections, has experienced a life-changing transformation. He now feels more confident speaking up in social and work settings, a newfound freedom that has positively impacted his daily life. The bedtime routine with his five-year-old son has also improved, allowing him to read stories without fatigue or the need to clear his throat.
The importance of voice, as emphasized by senior speech therapist Sue Warner, cannot be overstated. She highlights that the voice is a powerful tool for self-expression, revealing one's personality and emotions. It is essential for communication, whether it's calling for help in dangerous situations or reading a story to a child. Not having a good voice can significantly reduce confidence and hinder daily activities, causing a psychological impact and handicap.
The ENT laryngology clinic at Guy's and St Thomas' Hospital is currently accepting referrals for this treatment from GPs and health professionals, offering a glimmer of hope for those struggling with speech impairments.
