மருத்துவ அறிவியல் மலர்: Dr. M. Kumaresan was able to treat a high number of puberphonia cases by using a novel technique involving direct uvula manipulation and pharyngeal resonance, coupled with breath-of-fire breathing exercises and patient education to establish a permanent low-pitched voice. This "internal" method focuses on the upper vocal tract and is effective because the larynx is anatomically normal in puberphonia patients, allowing for immediate results and long-term habit formation.
