Clinical Research
Clinical research consists of overseeing clinical studies of patients undergoing new treatments and therapies, and publishing articles in peer reviewed medical journals. Providers who actively participate in clinical research are generally at the forefront of the fields and aware of the most up-to-date advances in treatments for their patients.
Johns Hopkins Outpatient Center
Lee Akst, M.D., specializes in treating the larynx (voicebox), in particular the treatment of voice and swallowing disorders. He is a leading laryngologist in office-based procedures such as vocal fold injection augmentation, pulsed KTP laser treatment, and laryngeal botox injection. In the operating room, Dr. Akst specializes in phonosurgery for the treatment of vocal cord disease, with emphasis on voice restoration and improvement. A strong focus of his practice involves the use of pulsed angiolytic lasers, which allow for subspecialized care of laryngeal papillomas, laryngeal dysplasia, and early vocal cord cancers while preserving the quality and strength of the voice. Dr. Akst is a national leader in the field of laryngology and serves in leadership roles for the American Laryngological Association, the American Broncho-Esophagological Association, and the American Academy of Otolaryngology-Head and Neck Surgery. He lectures extensively on the treatment of laryngeal disease, teaching other physicians how to care for patients with voice and swallowing concerns. His research interests include the development of robotic laryngeal surgery, the study of voice and swallowing complaints in the elderly, and the advancement of pulsed lasers for the treatment of laryngeal diseases with a focus on leukoplakia. This provider is registered with the Florida Department of Health to perform telehealth services for patients in Florida. Dr. Akst is rated as an Elite provider by MediFind in the treatment of Perichondritis. His top areas of expertise are Spasmodic Dysphonia, Laryngitis, Perichondritis, Endoscopy, and Laryngectomy.
Johns Hopkins Outpatient Center
Alexander Hillel specializes in the medical and surgical management of patients who have scar tissue blocking their larynx and/or trachea, a condition called laryngotracheal stenosis. This condition occurs in patients who have had prolonged intubation, an autoimmune disease or a rare disease called idiopathic subglottic stenosis. He also treats patients with voice and throat problems, including spasmodic dysphonia and swallowing difficulty. After he earned his medical degree from the Tulane University School of Medicine, Dr. Hillel completed his residency in otolaryngology–head and neck surgery at the Johns Hopkins University School of Medicine and a fellowship in laryngology and airway surgery at the Emory Voice Center. Dr. Hillel directs a laboratory that seeks to better understand why scar forms in the larynx and trachea. In an effort to improve treatment, he and his team investigate the relationship between the immune system, bacteria and other antigens and scar formation in the airway. He has led a number of clinical trials to improve treatment for subglottic stenosis, including the first interventional study for idiopathic subglottic stenosis. Researchers in Dr. Hillel’s lab are also testing drugs that may halt the progression of, or reverse, scar formation, and they have engineered a drug-eluting stent that is being tested to translate to patients with subglottic stenosis. He holds sponsored grants to conduct his research from the National Institutes of Health, surgical foundations and the medical device industry. In addition to clinical and research work, Dr. Hillel has a leadership role within the Department of Otolaryngology–Head and Neck Surgery, serving as the vice director of education. Dr. Hillel is rated as a Distinguished provider by MediFind in the treatment of Perichondritis. His top areas of expertise are Spasmodic Dysphonia, Subglottic Stenosis, Perichondritis, Laryngectomy, and Endoscopy.
