Learn More About  Dr. Silverstein's Inventions  and Procedures

Herbert Silverstein, MD, FACS, President and Founder of the Silverstein Institute and the Ear Research Foundation, has consistently been recognized (since 1979) as one the “Best Physicians in the USA.” He has been a leader in Otology/Neurotology (science of the ear and skullbase) for more than 40 years, developing surgical and diagnostic procedures, inventing instruments (such as the facial nerve monitor/stimulator), teaching medical students, residents and fellows, and helping people improve their quality of life. Born in Philadelphia, Dr. Silverstein received his BS degree from Dickinson College (cum laude), and both MS (in physiology) and MD degrees from Temple University Medical School. Before coming to Sarasota in 1973, he served on the teaching staff of Harvard University Medical School, Massachusetts Eye & Ear Infirmary, as director of the Walker Biochemistry Research Laboratory, and as associate professor and director of the Otological Research Laboratory at University of Pennsylvania Medical School.

He is internationally regarded as a leading authority on Ménière's disease, having received the Prosper Meniere’s Society’s prestigious Gold Medal Honor Award in 1996 for his contributions to understanding the biochemistry of Meniere’s disease and his surgical developments to treat the disease. He developed the microsurgical posterior fossa vestibular neurectomy which relieves the patients vertigo attacks while preserving the hearing. He developed a new procedure for otosclerosis to free the frozen stapes bone, the Laser STAMP (Laser Stapedotomy Minus Prosthesis), which does not require a prosthesis to restore the patients’ hearing. He has been a pioneer in developing minimally invasive surgical techniques including laser tympanostomy and the Silverstein MicroWick which allows the patient to deliver medication to the inner ear though the ear canal to treat sudden deafness and Ménière's disease. Recently he has pioneered treating Hyperacusis with a minimally invasive procedure, round and oval window reinforcement which reduces the sound vibrations of the stapes and round window membrane. 

He is Board Certified in Otolaryngology and is a Fellow of the American College of Surgeons. He is an active member of the American Otological Society, AmericanNeurotology Society and the Triologic Society. He is on the active staff at Sarasota Memorial Hospital and Cape Surgery Center.

In 1979, Dr. Silverstein founded the Ear Research Foundation. Today, he serves as its president, as well as its Medical Director. An active researcher, Dr. Silverstein speaks at many international medical meetings and is the author of over 248 scientific papers, textbook chapters and 7 textbooks, and videos. Among his many honors and accolades are the 2nd Howard P. House Award for Excellence in Ear Surgery, and the 10th Prosper Meniere Society Gold Medal Honor Award. He has been elected to the Best Doctors in the U.S.A. repeatedly since 1979. Other honors include President: Otosclerosis Study Group 1998, Guest of Honor: Canadian ENT Society 1999, Guest of Honor: The Triologic Society Southern Section 2002, Presidential Citation: American Academy of Otolaryngology 2002, President : Otosclerosis Study Group 2005, Award of Merit: American Otological Society 2006, and the AAO-HNS Howard House Memorial Lecture, 2017.

Seth I. Rosenberg, MD, FACS, specialist in ear disease and sinus disorders adds a valuable complement to services provided at the Florida Ear & Sinus Center. His special interests include surgical hearing restoration, balance disorders and sinus surgery.

A native of Poughkeepsie, New York, he completed a BS in chemistry, cum laude, at Rensselaer Polytechnic Institute prior to obtaining his MD at State University of New York Upstate Medical Center in Syracuse. His surgical and otolaryngology residencies were also served at SUNY.

Following the completion of his internship and residency, Dr. Rosenberg spent one year of specialized study in otology and neurotology at the Ear Research Foundation. Upon graduating the Fellowship, he was asked to join the staff of the University of Pennsylvania, Department of Otorhinolaryngology, Head and Neck Surgery, as an Assistant Professor. During this time, he quickly developed new surgical techniques and a national level practice in ear and skull base surgery. At the same time the University of Pennsylvania was an original center for endoscopic sinus surgery in the United States, so Dr. Rosenberg also cultivated a special interest in the treatment of paranasal sinus disease.  He brought this technique to Sarasota in 1991. He then went on to develop ways to use the same endoscopes for minimally invasive ear surgery. In 1994, while seeing a need in this community, Dr. Rosenberg introduced various techniques for the treatment of snoring and sleep apnea. One method, the CO2 LASER, is also used for in-office minimally invasive ear surgery.

Since 1991, Dr. Rosenberg has collaborated with Dr. Silverstein in many productive research endeavors. He serves as Vice President and Education Director for the Ear Research Foundation, and has co-authored over 70 scientific publications. He is still a clinical assistant professor at University of Pennsylvania Medical School, Department of Otolaryngology – Head and Neck Surgery. He is also a clinical assistant professor at USF Medical School, Division of Otolaryngology.

Dr. Rosenberg is Board Certified in Otolaryngology (Ear, Nose, and Throat) and a Fellow of the American College of Surgeons. He holds membership in many medical organizations, including the American Academy of Otolaryngology – Head and Neck Surgery. In 2000, he became a member of the prestigious Triological Society, receiving the Mosher Award for his thesis “The Natural History of Acoustic Neuromas”. The following year, he became one of the youngest members of the exclusive American Otological Society. Dr Rosenberg is on the staff of Sarasota Memorial Hospital, Venice Regional Medical Center, Doctors Same Day Surgery Center, as well as The Cape Surgery Center.

Microsurgical ear procedures, Acoustic Neuromas, Cochlear implants and implantable hearing devices, Treatment of dizziness and balance disorders

Jack J. Wazen, MD, FACS - A partner in the practice, Dr. Wazen was also the Silverstein Institute’s first research fellow. He left Sarasota in 1983 to build a successful Ear, Nose & Throat specialty practice in New York and spent 23 years as a researcher, professor and practitioner with Columbia University and the Columbia-Presbyterian Medical Center.

Recognized repeatedly as one of New York’s and America’s “Best Doctors,” Dr. Wazen is one of the nation’s leading authorities on hearing and balance disorders, pioneering new research that expanded treatments for people with single-sided deafness and complex cases of hearing loss. He also is author of the seminal book, Dizzy, providing new treatment options and hope for people affected by balance and hearing disorders.

In addition to providing medical care in the office, Dr. Wazen is an experienced otological/neurotological surgeon trained to restore hearing through microsurgical procedures, such as stapedectomy to correct ear bone degeneration (otosclerosis) and other minimally invasive techniques to cure birth defects, infection or disease (such as Meniere’s). He also specializes in surgical removal of tumors (acoustic neuromas and skull based lesions), as well as insertion of implantable hearing devices and cochlear implants (electrodes placed in the inner ear to restore severly impaired hearing).

Committed to finding new and better cures for hearing and balance disorders, Dr. Wazen serves as the Director of Research for the Institute’s non-profit Ear Research Foundation. Just as past studies uncovered new options to restore hearing, Dr. Wazen believes new and better treatments are imminent for people suffering from debilitating inner ear diseases like tinnitus (ringing in the ears) and dizziness and balance disorders.

Vocal cord paralysis, Spasmodic Dysphonia, Voice and swallowing disorders

John Paul (J.P.) Gniady, MD, FACS - Dr. Gniady was born and raised in New Orleans, Louisiana. He attended Louisiana State University for college and medical school and then went on to complete his residency in Otolaryngology – Head and Neck Surgery at Temple University Hospital in Philadelphia, Pennsylvania. Upon completion of his residency, Dr. Gniady travelled to Boston for a year of additional training in Laryngeal Surgery at Harvard’s Massachusetts General Hospital with the world renowned Dr. Steven Zeitels. Dr. Zeitels is best known for treating famous singers; ranging from The Who’s Roger Daltry, Steve Tyler of Aerosmith, Adele, and numerous operatic stars. He is however best known within the medical community for advancing the science and art of voice preservation and restoration for a variety of both benign and cancerous diseases of the larynx through the development of new surgical instruments and techniques. Dr. Gniady is now able to bring those techniques and technologies developed by Dr. Zeitels to patients across the Gulf South. He now practices with the Silverstein Institute in Sarasota, Florida where he has found a similar spirit of dedication to innovation and the advancement of patient care. When Gniady joined the Silverstein Institute in 2010, he brought a level of training and technology in laryngology that has been sought out by celebrities worldwide. 

Dr. Gniady helps patients with vocal cord paralysis, spasmodic dysphonia, and voice and swallowing disorders associated with Parkinson’s disease. He empathizes with patients who have these difficulties, and enjoys being able to help them, because these issues impact socialization and can cause people to avoid important social interactions like going out to dinner. Dr. Gniady emphasizes the importance of early treatment, which is particularly critical with cancer diagnoses. He encourages those with voice issues lasting more than a few weeks, or which disrupt their lives or work, to see a doctor right away.
Dr. Gniady initially was interested in a career in healthcare policy and decided it would he helpful to attend medical school to gain better insight. Instead, he found he enjoyed the clinical side of medicine. Dr. Gniady received his medical degree from Louisiana State University School of Medicine and his residency training at Temple University Hospital before completing his Harvard fellowship. Having grown up steeped in the musical ambiance of New Orleans, and as a musician himself, Dr. Gniady naturally was drawn to laryngology and still enjoys both the field’s fascinating science and the ability to help improve his patients’ lives.
