Groundbreaking Research and Clinical Trials

Dr. Klein brings to Emory a record of contributions in the field of laryngology that have helped advance the diagnosis and treatment of voice disorders. He was first to describe the use of a unique imaging technology, Polarization-Sensitive Optical Coherence Tomography, in the larynx, to aid in better identification of the pathologic states of the vocal folds.

His research and clinical practice largely focus on the treatment of benign and malignant glottal mucosal disease. He was the first to perform awake laser procedures in Georgia for the treatment of laryngeal disease, and he is currently involved in several clinical trials examining various chemotherapeutic prevention regimens for premalignant and early malignant lesions of the larynx. Dr. Klein also has forged collaborative bridges with scientists at the Georgia Institute of Technology, resulting in several translational research projects, with a focus on vocal fold reanimation.

Another area of interest and accomplishment is in phonosurgical training. Dr. Klein co-authored the first laboratory atlas describing the techniques of phonosurgery (voice surgery). To further improve the skills of other surgeons, he helped to develop and validate a phonomicrosurgical trainer. Currently, he is working on further improvements to this important component of modern day surgical training. In an effort to raise the standard of surgical training outside of the United States, Dr. Klein has created an observational fellowship program for Latin American physicians.

Dr. Klein has a musical background that led him to his profession as a laryngologist. Through his experience as a vocal performer and an otolaryngologist, he recognized that voice disorders were under-diagnosed and poorly addressed so he pursued additional training in the care of voice and voice disorders. In an effort to continue to fill in health care gaps, he started the first pediatric voice clinic in Georgia. Dr. Klein speaks Spanish conversationally, and lectures/teaches throughout Latin and South America.
