Summary
Acupuncture on voice-related acupoints improved vocal function and quality of life in patients with vocal fold lesions. Genuine acupuncture also led to significant structural healing of these lesions.
Area of Science:
- Integrative Medicine
- Otolaryngology
- Acupuncture Research
Background:
- Phonotraumatic vocal fold lesions are common causes of dysphonia.
- Current treatment options may have limitations, necessitating exploration of alternative therapies.
Purpose of the Study:
- To evaluate the efficacy of acupuncture in treating phonotraumatic vocal fold lesions.
- To assess acupuncture's impact on vocal function, quality of life, and lesion morphology.
Main Methods:
- A randomized controlled trial involving 123 individuals with benign vocal pathologies.
- Participants were assigned to genuine acupuncture, sham acupuncture, or no treatment for six weeks.
- Vocal function, quality of life, and endoscopic data were collected and analyzed.
Main Results:
- Both genuine and sham acupuncture groups showed significant improvements in vocal function and perceived quality of life compared to the no-treatment group.
- Only the genuine acupuncture group exhibited significant structural improvements, with a reduction in vocal fold lesion size.
Conclusions:
- Acupuncture targeting voice-related acupoints can enhance vocal function and promote healing of vocal fold lesions.
- Genuine acupuncture demonstrates potential for structural recovery of vocal fold pathologies.
