I am committed to recognizing patients’ individual values and preferences towards a shared goal of improving their symptoms and quality of life. I strive to provide compassionate, evidence-based care and use a team-based approach. It is my mission to improve my patients' hearing, as I share Helen Keller’s view that 'Blindness separates us from things, but deafness separates us from people'.
Dr. Sagiv’s clinical interests include treatment of chronic ear diseases, including tympanic membrane perforation, cholesteatoma, and chronic mastoiditis. Dr. Sagiv masters both the traditional, microscopic approach for ear surgeries and the minimally invasive endosopic approach. Dr. Sagiv also focuses on hearing rehabilitation surgeries such as ossicular chain reconstruction, stapedectomy (otosclerosis), and implantation of both cochlear implants and bone anchored hearing aids. His clinical practice encompasses medical and surgical treatment for vestibular disorders including BPPV, Ménière's disease, and superior semicircular canal dehiscence. In the field of lateral skull-base surgeries, Dr. Sagiv specializes in repair of CSF leak and encephalocele, and the management of acoustic neuroma and meningioma (both surgical and radiation treatments).
During his entire career, Dr. Sagiv combined research with his role as a clinician and a surgeon. This unique combination has allowed him to identify clinical needs during clinic visits and surgeries, and has led to numerous clinical trials and basic research projects that provided evidence-based answers to different clinical dilemmas. His studies have been presented in the highest impact international meetings in the field of Otolaryngology.
Dr. Sagiv's main research interest is the regeneration of the tympanic membrane (ear-drum). He conducts translational studies, from bench to bedside, in which he combines regenerative medicine methodologies and surgical needs with an ultimate goal to improve the healing rate of tympanic membrane perforation. Dr. Sagiv is currently developing a novel protocol that will enable production of a neo-tympanic membrane from the patient's own cells.
Dr. Sagiv's research topics also include cochlear implantation, endoscopic ear surgeries, infectious diseases of the ear, anatomy, trauma, treating the geriatric population, and head & neck oncology diseases.
